Servonaut

dev.servonautPublished by servonaut.devv2.32.0Updated Nov 6, 2026

Manage AWS, Hetzner, OVH and SSH servers: status, logs, CloudWatch, IP bans, safe command exec.

Overview

AI-generated overview

Servonaut's MCP server gives an AI assistant tools to inspect and operate AWS, Hetzner, OVH and custom SSH servers: status, logs, IP bans and guarded command…

What you can do
  • List and search a multi-provider fleet (AWS EC2, Hetzner, OVH, custom SSH hosts) and run lifecycle actions
  • Run remote commands, stream logs, browse files, transfer files over SSH/SCP and probe system health
  • Browse CloudWatch Logs and CloudTrail, analyze top IPs and ban IPs via WAF, security groups or NACLs
  • Inspect Docker, manage SSH keys, query cached server memory and use an authenticated REST proxy
  • Analyze logs with an AI provider and resolve database credentials from a local vault
When to use it
Useful when you want a coding agent to diagnose or operate real servers — checking instance state, tailing logs, running commands or triaging security events — without switching to a terminal. It is aimed at agent and headless setups; the project says humans should use its TUI instead.
Requirements
Local Python 3.10+ install (pipx or pip, e.g. the servonaut[mcp] extra) run as a stdio process; AWS CLI credentials in ~/.aws/credentials and ~/.aws/config with at least ec2:DescribeInstances and ec2:DescribeRegions, plus extra permissions for CloudWatch, CloudTrail and IP-ban features; an SSH client; optional OVH or Hetzner API credentials and AI provider keys in ~/.servonaut/config.json.
Before you install
Tools can change infrastructure: lifecycle actions (create, stop, reboot, delete), IP bans, SSH-key changes and remote command execution. Guard levels (readonly, standard, dangerous) and a JSONL audit trail apply, but confirm the level in use. AWS, OVH, Hetzner and AI provider credentials are read from local config; keep them out of the config file via environment-variable or file references. Optional hosted features need a Servonaut account login.

Installation

In SourceWeft

  1. Open Servonaut in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

Quick Install

Linux / macOS:

bash
curl -fsSL https://github.com/zb-ss/servonaut/releases/latest/download/install.sh | bash

Windows (PowerShell):

powershell
irm https://github.com/zb-ss/servonaut/releases/latest/download/install.ps1 | iex

The scripts come from the latest stable release and install Servonaut from PyPI with pipx. Every release carries them with install-scripts_SHA256SUMS, to check a downloaded copy before you run it.

Or install directly via pipx / pip:

bash
pipx install servonaut

Desktop app (preview), Linux: download the .deb from servonaut.dev/download, and see the Linux desktop preview notes before you install it.

Desktop app (preview), macOS 13 or later: releases that carry it have a signed and notarized disk image for Apple silicon (macos-arm64.dmg) and one for Intel Macs (macos-x64.dmg) on the releases page; see the macOS desktop preview notes. Both desktop previews tell you when a newer one is out, and never install it by themselves.

Try a release candidate

Each release is published as a release candidate (for example 2.28.0rc1) a few days before the stable release. Candidates are for people who want the next release early and will report what goes wrong. pip and pipx install one only when you ask for it.

bash
# The newest candidate, with the install scriptcurl -fsSL https://github.com/zb-ss/servonaut/releases/latest/download/install.sh | bash -s -- --pre
# With pipx: a specific candidate, or the newest onepipx install --force 'servonaut==2.28.0rc1'pipx install --force 'servonaut>=0rc0'
# With pippip install --upgrade 'servonaut>=0rc0'
# Try one without changing your installationpipx run --spec 'servonaut==2.28.0rc1' servonaut
# Go back to the newest stable release (your configuration is kept)pipx install --force servonaut

On Windows, run $env:SERVONAUT_PRE = "1" before the PowerShell installer. Avoid pip install --pre and pipx install --pip-args=--pre: they also install pre-release versions of Servonaut's dependencies, and some of those do not work with it.

While you run a candidate, the update check offers newer candidates and then the stable release. A stable installation is only ever offered stable releases. Please report problems in GitHub issues. Details: Release candidates.

Standalone CLI preview

Standalone console-only archives are being validated for Windows x64, macOS Intel and Apple Silicon, and Ubuntu x64. They are not published or downloadable yet. Until signed release installers are available, install Servonaut with pipx or pip.

Manual install from source:

bash
git clone https://github.com/zb-ss/servonaut.gitcd servonautpipx install .

Set up with an AI agent

Prefer to let an AI agent do the whole thing? Paste this prompt into Claude Code, Cursor, or any coding assistant — it installs Servonaut, generates the config, and walks you through AWS / SSH / bastion / custom-server / AI-provider setup plus the MCP server.

Copy-paste setup prompt
Install and configure Servonaut, a TUI for managing servers (AWS EC2, OVHcloud, Hetzner Cloud, and custom SSH servers).
1. Install with all optional features: `pipx install 'servonaut[all]'`   (bundles the MCP server + OVH/Hetzner SDKs + keyring; AI log analysis needs no extra. Use plain `pipx install servonaut` for a minimal install.)2. Run `servonaut` once to generate ~/.servonaut/config.json3. (Optional) If I have a Servonaut account, run `servonaut login` to unlock the hosted features: Servonaut AI (chat with my fleet, no local API key), config sync across machines, Memory Sync, and proactive monitoring (Findings). Servonaut works fully offline against my own credentials if I skip this.4. Read ~/.servonaut/config.json and help me configure:   - AWS regions to scan (default scans all, set `regions` array to limit)   - Default SSH username (`default_username`, default "ec2-user")   - Cache TTL (`cache_ttl_seconds`, default 3600)   - Terminal emulator if not auto-detected (`terminal_emulator`)5. If I use bastion/jump hosts, help me set up `connection_profiles` and `connection_rules`6. If I have non-AWS servers, help me add them to `custom_servers`7. If I use OVHcloud or Hetzner Cloud, help me add the API credentials so those instances merge into the fleet8. For AI log analysis or chat with my own model (instead of Servonaut AI), help me configure `ai_provider` (openai/anthropic/gemini/ollama)   - Each provider has its own key field (`openai_api_key`, `anthropic_api_key`, `gemini_api_key`, `ollama_api_key`); local Ollama needs none   - Key fields support `$ENV_VAR` and `file:~/.secrets/key` syntax so secrets stay out of the config file9. Install the MCP server into my coding agent: `servonaut --mcp-install claude` (or `cursor`, `windsurf`, `opencode`, `vscode`, `codex`, `agy`, `gemini`, `all`)10. (Optional) To let AI agents/teammates reach this machine over the relay — and to run proactive Findings scans — start it with `servonaut connect`
After setup, launch with `servonaut` and walk me through the key features, including the Findings inbox if I enabled the hosted features.

Features

Badges: Solo+ = included with paid Solo/Teams plans.

Core & connectivity

  • Interactive TUI — mouse + keyboard, powered by Textual.
  • Multi-provider fleet — AWS EC2, OVHcloud (dedicated / VPS / Public Cloud), Hetzner Cloud, and custom servers from any provider (DigitalOcean, on-prem, …) — listed and searchable in one view across all regions.
  • Multiple accounts per provider — several AWS accounts (named profiles), Hetzner projects and OVH accounts in the same fleet; servers show as account/name and every action runs in the server's own account. → docs
  • Per-instance dashboard — click a server for a Server Actions view: a memory snapshot (OS, disk, web stack, databases, runtimes, containers) plus an opt-in live resource monitor (L — CPU / RAM / load / disk / uptime, polled only while open).
  • SSH & SCP — one-key SSH in a new terminal window (auto-detected emulator); upload/download files and directories.
  • Run remote commands — overlay panel with real-time streaming output, history, and saved favorites.
  • Remote file browser — interactive file-tree navigation, inline in the dashboard or full-screen.
  • Real-time log viewer — stream logs via tail -f with pause, search, and log switching.
  • Robust SSH — bastion / jump-server (ProxyJump / ProxyCommand), keepalives on by default (tunable), per-host extra_ssh_options for legacy boxes, and key auto-discovery.
  • SSH host-key checking — trust on first use: the first connection records a server's host key, and a later connection presenting a different key is refused, with the exact command that removes the old key once you have confirmed the change. → docs

Cloud provider management

  • OVHcloud — OVH → ⚙ Manage: create / start / stop / reboot / delete (Cloud / VPS / dedicated), a region-first create wizard with API-backed pricing, plus DNS, IP blocks & failover IPs, snapshots, block storage, and billing.
  • Hetzner Cloud — Hetzner → ⚙ Manage: full lifecycle + project SSH-key registry, with an equivalent CLI (servonaut hetzner …). Auto-registers new servers. → docs

Observability & security

  • Proactive monitoring — Findings (Solo+) — cloud-side detectors surface fleet issues (disk, failed services, slow queries, credential-scanning cross-referenced with fail2ban, container health, TLS expiry, pending updates) as triageable cards, with gated one-click remediation (server-signed preview → human confirm → verb-allowlisted executor; block IP or renew a cert). → guide
  • CloudWatch Logs browser — log groups with Top-IPs analysis, IP geolocation, and AbuseIPDB lookups.
  • CloudTrail browser — AWS CloudTrail events with region / time / event / user filters.
  • IP ban manager — ban IPs via AWS WAF, Security Groups, or NACLs, with an audit trail.
  • Keyword server scanning — search file contents across instances.

AI

  • Servonaut AI (Solo+) — hosted AI gateway; chat with your fleet with no local API key. The model can tail logs, run commands (with confirmation), and triage incidents over the relay — credentials and SSH keys never leave the CLI. Quota inline / servonaut ai quota.
  • Bring your own key — OpenAI / Anthropic / Gemini / Ollama keys configured per-provider in Settings → AI Provider (local Ollama needs none). All coexist with Servonaut AI, switchable per-session.
  • Built-in AI chat — LLM assistant with tool-calling against your instances (the same MCP tool surface below).
  • AI log analysis — analyze logs with OpenAI, Anthropic, Gemini, or Ollama, with cost estimation.
  • Voice — dictate into the chat panel with ctrl+t, have replies read aloud, or go fully hands-free with conversation mode (ctrl+n): the mic stays open between turns and replies are spoken — with optional barge-in (headphones mode) to interrupt a reply by talking over it. Transcription and speech synthesis run entirely on your machine, so audio never leaves the workstation. Opt-in — nothing is downloaded until you enable it in Settings. → docs

Memory & secrets

  • Server memory — persistent per-server cache of OS / runtime / service / web-stack / log / database / container / git / disk facts; optional background fleet auto-scan. → docs
  • Memory Sync (Solo+) — end-to-end-encrypted backup of fleet memory to servonaut.dev (X25519 + AES-256-GCM, your passphrase), with drift detection, cross-device history, and optional auto-sync. ☁ Memory Sync in the sidebar.
  • Database credential vault (Solo+) — scan a server for the DB credentials its apps already use, store the password in your secret vault under a per-site label, and let the db_* tools resolve it by name — no password in config or agent context. → docs

Agents & automation (MCP)

  • MCP server — ~80 tools for Claude Code, Cursor, Windsurf, etc.: instance ops, AWS / Hetzner / OVH lifecycle, S3, log analysis & IP banning, Docker inspection, system-health probes, SSH-key CRUD, memory queries, and an authenticated REST proxy — behind a three-tier guard (readonly / standard / dangerous) with a JSONL audit trail. → details below
  • MCP relay — servonaut connect (or TUI autostart) holds a Mercure SSE connection open so agents and team-mates can dispatch tool calls to this machine. Tokens never leave the CLI.
  • Team agent rules (Teams plan) — team owners and admins decide what members' AI agents may do on the team's shared servers: a level per role and per server, allowed commands and blocked patterns. The rules are signed by servonaut.dev and checked by every member's Servonaut, for the AI chat with any provider, relayed Servonaut AI tool calls and every MCP agent; rules that cannot be checked leave the team's servers read-only. → docs
  • Team vault keys (Teams plan) — team owners and admins bind SSH keys from the team's vault to its shared servers, one server at a time or all at once with Auto-bind; members connect with them without holding the keys. → docs
  • Servonaut Cloud account — optional servonaut login unlocks config sync across machines and the MCP relay.
  • Config sync — client-side-encrypted snapshots of your config.json synced via servonaut.dev, paired with a passphrase you control.

Convenience

  • Instance caching — stale-while-revalidate for fast startup.
  • Auto-update — startup check + one-click update (servonaut --update). Stable installations are offered stable releases only; see Release candidates.
  • Terminal shortcut — servonaut --install-desktop adds a launcher that opens the TUI in a terminal: Servonaut (terminal) on Linux, Servonaut Terminal in ~/Applications on macOS.
  • Fully configurable — everything in ~/.servonaut/config.json.

Prerequisites

  • Python 3.10+
  • AWS CLI configured (~/.aws/credentials and ~/.aws/config)
  • SSH client (standard on Linux/macOS, OpenSSH on Windows)
  • pipx for isolated installation (recommended)

Your AWS credentials need ec2:DescribeInstances and ec2:DescribeRegions permissions. Additional permissions needed for optional features:

FeatureRequired Permissions
CloudTrail browsercloudtrail:LookupEvents
IP ban (WAF)wafv2:GetIPSet, wafv2:UpdateIPSet
IP ban (Security Groups)ec2:AuthorizeSecurityGroupIngress, ec2:RevokeSecurityGroupIngress, ec2:DescribeSecurityGroups
IP ban (NACLs)ec2:CreateNetworkAclEntry, ec2:DeleteNetworkAclEntry, ec2:DescribeNetworkAcls
CloudWatch Logslogs:DescribeLogGroups, logs:FilterLogEvents
Verify host keys in Auto-bindec2:GetConsoleOutput
OVHcloud (optional)OVH API credentials — 3-key (application key / secret / consumer key) or OAuth2. Set up via servonaut --setup-ovh or in Settings.

Getting Started

bash
servonaut

That's the whole interface. The TUI is the primary and recommended way to use Servonaut — every feature (fleet view, SSH, remote commands, logs, IP banning, AI chat, server memory, provider management) is reachable from the sidebar, with full mouse and keyboard support.

A few flags you may want on day one:

bash
servonaut --update                # Check for updates and upgradeservonaut --install-desktop       # Add a launcher that opens the TUI in a terminal (Linux/macOS)servonaut --setup-ovh             # Guided OVHcloud credential setupservonaut --debug                 # Verbose logging to stderr

Headless & automation: every major feature also has a scriptable CLI (servonaut connect, servonaut memory, servonaut ai, servonaut hetzner, servonaut secrets) for CI runners, cron jobs, and boxes without an interactive session — see the CLI Reference.

What You Can Do

The TUI opens to a unified instance list (AWS + OVH + Hetzner + custom servers in one searchable table). The collapsible left sidebar groups everything else by purpose:

Core

  • 📋 Instances — search and SSH the unified fleet
  • 💻 Custom Servers — add / edit / remove non-AWS servers (DigitalOcean, on-prem, etc.)
  • 🔑 SSH Keys — configure default and per-instance keys

Logs & Security

  • 📊 CloudWatch — browse AWS log groups with Top IPs analysis, action filter (All/Allowed/Blocked), IP geolocation, AbuseIPDB lookup
  • 🔒 IP Ban Manager — ban IPs via WAF, Security Groups, or NACLs
  • 🔍 CloudTrail — audit AWS API activity with filters

Tools

  • 🧠 Fleet Memory — scan / refresh / inspect the AI-queryable fact cache, with an optional scheduled background auto-scan (bulk scans run in the background and survive leaving the panel)
  • ☁ Memory Sync — encrypted backup of fleet memory across devices (Solo+)
  • 🛡 Findings — proactive-monitoring inbox: scan, review, and triage server-detected issues fleet-wide (Solo+; Free shows an upgrade card)
  • 🔄 Sync Config — encrypted config snapshots (Solo+)
  • 🔧 Settings — configuration, scan rules, AI provider, AbuseIPDB key

OVH (visible when configured)

  • ⚙ Manage — table of OVH instances with state-aware lifecycle toolbar (Create / Start / Stop / Reboot / Delete)
  • 🔑 SSH Keys — project-level SSH key registry (the one the create wizard injects from)
  • DNS Zones · IP Management · Block Storage · Billing

Hetzner (visible when configured)

  • ⚙ Manage — table of Hetzner servers with full lifecycle toolbar (Create / Power on / Shutdown / Reboot / Delete)
  • 🔑 SSH Keys — Hetzner Cloud project SSH key registry

Account

  • Login · Teams · Bug Reports

Server Actions — clicking any instance row opens a per-instance dashboard: the detail pane shows the server's identity, a memory snapshot, and an opt-in live resource monitor (L), and the action rail covers:

  • Browse Files (inline) · Run Command · SSH Connect · SCP Transfer
  • View Scan Results · View Logs (tail -f) · AI Analysis · Monitoring (F)
  • Ban IP · Manage/Verify SSH Ref

The SSH Ref editor pairs with a Bitwarden vault — pick an SSH key from a list instead of pasting a UUID, or import keys straight from ~/.ssh (passphrase-protected included), so a machine with no local keys can still connect. The TUI, CLI, and MCP agents all resolve the key from your vault at connect time (Solo+). → docs

Command history persists across sessions — Ctrl+R to search history and saved commands, Ctrl+S to save favorites.

Instance Caching

ScenarioBehavior
First launch (no cache)Fetches from AWS with progress indicator
Restart within TTL (default 1h)Instant load from cache
Restart after TTLShows stale data immediately, refreshes in background
Press RForce-refresh from AWS

Configuration

All configuration lives in ~/.servonaut/config.json, created automatically on first run.

See Configuration Guide for the full reference including connection profiles, custom servers, scan rules, and match conditions.

SSH keepalives: all connections send keepalives by default so long or idle agent-driven sessions don't get dropped. Tune globally via the ssh block in config.json (server_alive_interval, server_alive_count_max, tcp_keepalive, connect_timeout).

Legacy / special-case SSH hosts: connection profiles and custom servers both accept an extra_ssh_options array that appends arbitrary -o KEY=VALUE flags per host — use it to talk to ancient OpenSSH boxes (HostKeyAlgorithms=+ssh-rsa), override keepalives, or set connect timeouts without weakening your global SSH defaults. See Per-host SSH tuning.

Secrets: API keys in config.json support $ENV_VAR and file:~/.secrets/key syntax so the config file stays secret-free. You can also create ~/.secrets/servonaut.env with KEY=value pairs — loaded automatically on startup.

Optional Dependencies

bash
# MCP server for AI agents (name any other extras you use, e.g. 'servonaut[mcp,ovh]')pipx install --force 'servonaut[mcp]'# or: pip install 'servonaut[mcp]'
# Hetzner Cloud / OVHcloud provider SDKspip install 'servonaut[hetzner]'pip install 'servonaut[ovh]'
# Voice — all processed locally, nothing sent to a speech servicepip install 'servonaut[voice]'            # voice input, batch enginepip install 'servonaut[voice-streaming]'  # voice input, live text as you speakpip install 'servonaut[voice-output]'     # spoken replies / conversation mode
# Install everythingpip install 'servonaut[all]'

The batch voice engine (servonaut[voice]) needs Python 3.14 or earlier for now: its speech runtime publishes no Python 3.15 build yet. On 3.15, servonaut[all] installs everything else, including the streaming engine and spoken replies.

Voice also needs the PortAudio system library (sudo apt install libportaudio2, brew install portaudio) and one-time model downloads, both surfaced in Settings → AI → Voice Input. See docs/voice.md.

AI log analysis (OpenAI, Anthropic, Gemini, Ollama) needs no extra install — httpx ships as a base dependency.

MCP Server for AI Agents

This section is for wiring up AI agents (Claude Code, Cursor, Windsurf, …) — not day-to-day interactive use. If you're a human operating your fleet, the TUI above is the recommended interface.

Servonaut includes an integrated MCP server that exposes tools to AI agents like Claude Code:

bash
# Auto-install into a coding agentservonaut --mcp-install claude     # Claude Codeservonaut --mcp-install cursor     # Cursorservonaut --mcp-install windsurf   # Windsurfservonaut --mcp-install opencode   # OpenCodeservonaut --mcp-install vscode     # VS Code Copilotservonaut --mcp-install codex      # Codex CLIservonaut --mcp-install agy        # Antigravity CLIservonaut --mcp-install gemini     # Gemini CLIservonaut --mcp-install all        # All of the above
# Run MCP server manually (stdio transport)servonaut --mcp

Re-running an installer updates only Servonaut's launch command and required environment forwarding. Other MCP servers and user-owned settings such as timeouts, trust, tool filters, and custom environment entries are preserved. Secret values are never copied into agent configuration: supported clients use references, variable-name allowlists, or inherited environment to supply SSH/Bitwarden state, AWS credentials, Servonaut endpoints, and $ENV_VAR references found in the local Servonaut config. Invalid agent JSON is refused instead of overwritten, and config writes are atomic without replacing symlinked dotfiles.

If you change how Servonaut is installed (for example from pipx to the desktop app) and remove the old copy, the TUI and desktop app point agent entries that still name the removed command at the running installation when they start, and tell you which agents to restart. servonaut --mcp-repair runs the same check from the command line. See Switching how Servonaut is installed.

SSH-backed MCP tools first use the configured local or vault key. If that key cannot authenticate and SSH_AUTH_SOCK was forwarded, Servonaut retries once using the agent without forcing the configured identity. Authentication failures are returned and audited as failures, never as successful tool calls.

Agent-only / headless install

You don't need the TUI to use Servonaut as an agent toolbox. The MCP server runs fully headless — servonaut --mcp never loads the terminal UI (this is enforced by a regression test), so you can install it on a server or CI box purely as an MCP backend for your coding agent:

bash
pipx install 'servonaut[mcp]'servonaut --mcp-install claude   # or cursor, windsurf, opencode, vscode, codex, agy, gemini, all

Configure credentials and servers the same way as a TUI install ( ~/.servonaut/config.json, $ENV_VAR / file: secret syntax — see Configuration Guide). For Servonaut Cloud features (relay, config sync, hosted AI), servonaut login runs the device-flow sign-in fully headless — approve from a browser on any device. Everything an agent does goes through the same guard levels and is logged to ~/.servonaut/mcp_audit.jsonl.

SSH keys from Bitwarden (no keys on the box). If your instances have a Bitwarden SSH ref saved, the SSH-backed tools (run_command, get_logs, transfer_file, …) resolve the private key from your vault at connect time instead of needing it in ~/.ssh — so an agent on a fresh server or CI box can connect with no local keys at all. Because a headless process can't prompt for your master password, unlock the vault once and export the session into the environment the MCP server (or servonaut connect) runs in:

bash
export BW_SESSION=$(bw unlock --raw)   # unlock once; stays valid until you `bw lock` or the shell exitsservonaut --mcp                         # child inherits BW_SESSION

The key is written to a private, 0600 temporary file only for the duration of each command and deleted immediately after. If the vault is locked or bw isn't installed, the tools fall back to local keys — a working local setup is never affected.

The tool list is filtered to what's actually usable: OVH and Hetzner tools appear only when those providers are configured, the ip_ban_* tools only when at least one IP-ban target is defined, and the *_server_memory* tools only when the memory subsystem is enabled. CloudWatch/CloudTrail and the core instance tools are always available (AWS is the base provider).

  • cloudwatch_top_ips parses WAF/ALB structured logs to rank client IPs with allowed/blocked counts — pair it with cloudtrail_lookup_events to corroborate, then ip_ban_set to block via WAF, a security group, or a NACL.
  • whoami returns session metadata — the OAuth bearer is never exposed.
  • api_request lets an agent make authenticated REST calls against servonaut.dev with automatic 401 refresh and a CLI-side rate limit (30/min). The bearer stays on the CLI.
  • mcp_tool_call wraps a JSON-RPC 2.0 tools/call envelope against the hosted MCP at mcp.servonaut.dev — used for premium tools when your plan includes them.
  • get_server_memory(id) returns the cached fact snapshot — agents call this BEFORE any SSH round-trip so they answer most OS / runtime / service questions without run_command. Pass format='context_block' to get back a <CONTEXT> envelope for direct prompt injection.

Guard levels: readonly (list/status/introspection only — includes CloudWatch/CloudTrail and ip_ban_list_* queries), standard (read + safe commands + authenticated REST + power management — start / stop / reboot / shutdown + S3 download), dangerous (everything, including create_server / delete_server / transfer_file / ip_ban_set / aws_terminate_instance / aws_run_instances / S3 mutations (s3_create_bucket, s3_delete_bucket, s3_upload_object, s3_delete_object, s3_copy_object, s3_move_object, s3_generate_presigned_url)). Dangerous shell commands (rm -rf, shutdown, reboot, etc.) are always blocked regardless of guard level. Mutating tools carry an explicit "confirm with the user before calling" cue in their descriptions; the top-level MCP instructions document the three-step protocol (summarise → state args → wait for affirmative reply). All operations are logged to ~/.servonaut/mcp_audit.jsonl.

Servonaut Cloud account

Optional — Servonaut works fully offline against your own AWS / OVH credentials. Signing in at servonaut.dev unlocks:

  • Config sync — push/pull an encrypted snapshot of your config.json between machines. The passphrase never leaves your client; the server only sees ciphertext. Sidebar entry 🔄 Sync Config opens the snapshot manager directly (Pull Latest / Push New / Restore / Rename / Delete).
  • MCP relay — a Mercure SSE channel that lets AI agents and team-mates dispatch MCP tool calls to this machine. While the relay is connected, https://servonaut.dev/account reports your CLI as online, and hosted agents can reach it.
  • Memory Sync (Solo+) — encrypted fleet memory backup with drift detection. Open the ☁ Memory Sync sidebar entry, click Unlock Memory Sync, and enter a passphrase. The same screen handles first-time enrolment AND post-restart unlock — your private key is wrapped with the passphrase locally, so the server never sees it. After unlock, click Sync now to push every cached server's memory modules as encrypted envelopes, or flip on auto-sync to drain the queue in the background so the server-side copy (and weekly digests) stay current. Unlock survives restarts: tick Remember on this device to silently re-unlock from your OS keychain on the next launch (re-prompted after 30 days, or Forget on this device to clear it). If you decline, Memory Sync stays dormant until you next open a memory section. Per-feature settings (digest cadence, Mercure push, AI consent) live at the bottom of the Settings panel and are stored on your servonaut.dev account.

Sign in from the TUI's Account / Login screen. After a successful device-flow authentication, the TUI auto-starts an in-process relay listener and the sidebar indicator flips to ● connected.

The listener is tied to the TUI window — closing the TUI drops the connection after ~60 s. For always-on reachability (CI runners, headless boxes), use servonaut connect --bg instead; the CLI and TUI cooperate over ~/.servonaut/relay.lock so they can't run at the same time. The TUI shows external listener (PID N) when a --bg listener is holding the connection.

bash
servonaut connect                 # Foreground relay (Ctrl+C to stop)servonaut connect --bg            # Detach; writes ~/.servonaut/relay.pidservonaut connect --status        # Local + backend view with divergence warningservonaut connect --stop          # SIGTERM the background listenerservonaut connect --reconnect     # Heal a stale SSE socket (stop+start)servonaut connect --force-bg      # Take over from a TUI's in-process listener

See CLI Reference → servonaut connect for full flags.

Tokens are stored at ~/.servonaut/auth.json with mode 0600, written atomically via tmp + os.replace(). If an older build left the file world-readable, the next run auto-fixes it.

Proactive monitoring — Findings (Solo+)

Server-side detectors scan your fleet for problems and post each one as a triageable finding card: severity, description, evidence, and remediation options. Detection runs in the Servonaut cloud; this client only runs read-only probes over your relay connection and renders the results — nothing is analysed or decided locally.

  • Fleet inbox / per-instance — 🛡 Findings in the sidebar for the whole fleet, F (Monitoring) on any server for that instance.
  • Scan now (s) — dispatches read-only probes over the relay (servonaut connect or the TUI autostart must be running); inapplicable detectors report the reason instead of failing silently.
  • Triage — acknowledge (a), resolve (r), or suppress (x); status syncs server-side.
  • Gated one-click remediation — automatable fixes run only on an explicit click, from a server-signed preview, through a verb-allowlisted executor (typed confirmation for state changes, dry-run first, fully audited). Fixes today: block a source IP (AWS WAF / Security Group / NACL, or the box's own firewall — nftables / ufw / firewalld) and renew a TLS certificate.

Secrets management (Solo+)

Centralise SSH keys + other named secrets behind a pluggable provider backend. Day-to-day this is invisible: once configured, SSH key resolution checks your provider automatically on every connect — you keep clicking SSH in the TUI and it just works. The commands below are one-time setup. MVP supports two backends:

  • LocalProvider — keys live in ~/.servonaut/secrets.json (mode 0600, atomic write, same trust model as auth.json). Always available on Solo and Teams plans.
  • BitwardenProvider (bws) — keys live in your team's Bitwarden Secrets Manager project. Team admin configures the project from https://servonaut.dev/account/teams/<slug>/secrets; CLI fetches the metadata and reads/writes through the local bws binary using your own access token. The token never leaves your machine — servonaut.dev only stores the project ID and the name of the env var holding the token.

To use Bitwarden as your team's backend:

bash
# 1. Install the bws CLI (one-time)servonaut secrets install bws         # macOS: brew · Linux: cargo# Windows / other → prints upstream install URL.
# 2. Mint a BWS access token (https://bitwarden.com/help/personal-access-tokens/)#    and export itexport BWS_ACCESS_TOKEN=<your-token>
# 3. Verify wiringservonaut secrets status              # your plan and where secrets are kept (--json for scripts)
# That's it — SSH key resolution now checks Bitwarden first, ~/.ssh as# fallback. Push a key into BWS with `bws secret create`:bws secret create "$(basename ~/.ssh/prod-server)" \                  "$(cat ~/.ssh/prod-server)" \                  --project-id <project-uuid-from-status>

Key resolution order on every SSH connect:

  1. Active provider (Bitwarden, if configured) looked up by key name.
  2. ~/.ssh discovery (existing patterns + fuzzy match).
  3. The path stored in config.json::instance_keys[<id>] or config.default_key.

Free-tier users get the legacy ~/.ssh-only flow with zero behaviour change. Provider-supplied keys land in ~/.servonaut/keys/<name> at mode 0600.

Threat-model + design notes are pinned in the codebase via inline docstrings on services/secret_provider.py, services/bitwarden_provider.py, and services/secret_provider_resolver.py.

Database credential vault

The same secret store also backs a database credential vault: scan a server for the DB credentials its apps already use — .env / DATABASE_URL (including DATABASE_URL_PROD / _STAGING variants), wp-config.php, configuration.php, Magento env.php, and docker-compose environment: blocks, with a read-only sudo -n fallback so root-owned files and containerized stacks are covered. Store the password under a per-site label and the db_processlist / db_top_queries tools resolve it by name — the password never lands in your config or in an AI agent's context. A Secrets → DB coverage view lists which instances are covered per site, with in-place label and remove. Full docs
