EVC Team Relay - MCP Server

[Install via Spark]
Give your AI agent read/write access to your Obsidian vault.
Your agent reads your notes, creates new ones, and stays in sync — all through the Team Relay API.
Works with Claude Code, Codex CLI, OpenCode, and any MCP-compatible client.

Quick Start
1. Install
Option A — from PyPI (recommended):
No installation needed — uvx downloads and runs automatically. Skip to step 2.
Option B — from source:
2. Configure your AI tool
Add the MCP server to your tool's config. Choose one authentication method:
Agent key (recommended) — create a key in the Obsidian plugin → Team Relay settings → Agent Keys. Supports read and write: list_files, read_file, tr_search, and upsert_file all work with a single key. Quickstart →
Email + password — use a dedicated agent account on your Relay instance.
Claude Code — agent key
Add to .mcp.json in your project root or ~/.claude/.mcp.json:
Claude Code — email/password
Codex CLI
Add to your codex.json:
OpenCode
Add to opencode.json:
From source (all tools)
If you installed from source instead of PyPI, replace "command": "uvx" / "args": ["evc-team-relay-mcp"] with:
Environment variables:
Ready-to-copy config templates are also in config/.
3. Use it
Your AI agent now has these tools:
Typical workflow: list_shares -> list_files -> read_file / upsert_file
Authentication is automatic — the server logs in and refreshes tokens internally.
Tool availability matrix
Not every tool works in every auth mode, and one group doesn't work in
either mode — these are two unrelated facts, so don't conflate them:
- Write access requires an agent key:
upsert_file is the only write tool with a working backend route, and it
only writes when an agent key (RELAY_AGENT_KEY / RELAY_AGENT_KEYS) is
configured. JWT mode calling upsert_file raises a clear ValueError
naming agent-key mode as the fix, instead of a confusing 404.
read_document, write_document, and delete_file are a separate,
independent gap — the control plane has no backend route for them at
all, in agent-key mode either. Switching to an agent key will not
make them work: doc-share live content is CRDT/WebSocket-only (no REST
bridge), and per-file delete has no DELETE route server-side yet. If
routes for these are ever added, they'd still follow the agent-key-only
write policy above — JWT would stay read-only.
Remote Deployment (HTTP Transport)
For shared or server-side deployments, run as an HTTP server:
By default the server binds to 127.0.0.1 (localhost-only) — the endpoint is not
reachable over the network even if the host has a public IP. This matches the common
case of a single MCP client on the same machine as the server.
Then configure your MCP client to connect via HTTP:
Remote access via SSH tunnel (recommended)
If your MCP client runs on a different machine than the server, tunnel to the
localhost-bound port instead of exposing it publicly:
Then point the client config at http://127.0.0.1:8888/mcp as above — traffic
goes through the SSH tunnel, and the server's bind address never needs to change.
Public / reverse-proxy binding (opt-in)
If you genuinely need the server to accept connections from other hosts directly
(e.g. it sits behind a reverse proxy that terminates TLS and handles auth), pass
--host explicitly:
Only do this behind a reverse proxy or firewall — the MCP HTTP endpoint itself
has no built-in authentication, so binding it to 0.0.0.0 on an open network
exposes every relay tool call to anyone who can reach the port.
Security
The MCP server provides significant security advantages over shell-based integrations:
- No shell execution — all operations are Python function calls via JSON-RPC, eliminating command injection risks
- No CLI arguments — credentials and tokens are never passed as process arguments (invisible in
ps output)
- Automatic token management — the server handles login, JWT refresh, and token lifecycle internally; the agent never touches raw tokens
- Typed inputs — all parameters are validated against JSON Schema before execution
- Single persistent process — no per-call shell spawning, no environment leakage between invocations
Note: If you're using the OpenClaw skill (bash scripts), consider migrating to this MCP server for a more secure and maintainable integration.
How It Works
The MCP server wraps Team Relay's REST API into standard MCP tools. Team Relay stores documents as Yjs CRDTs and syncs them to Obsidian clients in real-time. Changes made by the agent appear in Obsidian instantly — and vice versa.
Prerequisites
- Python 3.10+ with uv (recommended) or pip
- A running EVC Team Relay instance (self-hosted or hosted)
- A user account on the Relay control plane
