AI-generated overview

Provisions a reproducible OpenCode development workstation on a local or SSH-reachable Linux box: inspect, plan, clone, verify, and manage components and…

What you can do
  • Describe the bundled Workbench profile and its component tiers and optional MCP add-ons
  • Inspect a local or SSH target for OS, toolchain, Docker and which credentials are present (names only)
  • Plan and apply a full profile clone, then verify per-component results
  • Install, update or remove individual components such as OpenCode, pnpm, MCP servers, skills and Docker containers
  • List required credentials and get acquisition guidance for each missing one
When to use it
Use it when you want to rebuild or standardize an OpenCode setup with its MCP servers, skills and plugins on a fresh or existing Linux machine, locally or over SSH, and want a read-only plan before anything changes.
Requirements
Runs as a remote streamable HTTP endpoint or locally via npx from the npm package (Node.js). Targets must be Linux, reachable locally or over SSH with the user's credentials. The profile references many provider keys (for example DEEPSEEK_API_KEY, OPENCODE_API_KEY, GITHUB PAT, PERPLEXITY_API_KEY, BROWSERLESS_TOKEN); the server only checks whether they are set.
Before you install
apply_clone, install_component and update_component write to the target: they overwrite the OpenCode config file, copy AGENTS.md, reset an existing profile repo to origin/main and run global installs. apply_clone is consent-gated and needs confirm:true. SSH access and privileged commands may be used. The README says secret values are never read or transmitted and only an empty env template is written, but the target machine and its configuration are modified.

Installation

In SourceWeft

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

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.ascent-partners%2Fopencode-workbench/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

OpenCode Workbench

A reproducible, self-documenting, and recoverable OpenCode development workstation — configuration, agent skills, MCP stack, and an MCP server that clones the entire setup onto any Linux machine (locally or over SSH).

Overview

This repository is the single source of truth for a complete cloud development workstation. Everything needed to rebuild from scratch is versioned here:

  • Workstation configuration and automation
  • OpenCode configuration (model, providers, MCP servers)
  • Agent skills (76 reusable AI instructions across research, dev, data, science and ops)
  • Operational prompts (disaster recovery, backup, security)
  • Recovery procedures (playbook, checklist, gap analysis)
  • Security governance (secret management, threat model)
  • OpenCode sandbox (bubblewrap) — run the agent with a read-only system and no secret mounts
  • opencode-workbench — an MCP server that installs this profile on any Linux box

No important knowledge exists only in human memory.

Clone This Workbench to Another Linux Machine

Register the MCP server with OpenCode:

json
{  "mcp": {    "opencode-workbench": {      "type": "local",      "command": ["npx", "-y", "@simonmak-ascent/opencode-workbench"],      "enabled": true,      "timeout": 600000    }  }}

Then ask the agent to run inspect_target → plan_clone → apply_clone { confirm: true } → verify_clone, for { "mode": "local" } or { "mode": "ssh", "host": "<your-box>", "user": "<your-user>" }. apply_clone is consent-gated: without confirm:true it returns a plan (components + privileged-command preview) and changes nothing. Run list_required_credentials to see which keys the box still needs and how to acquire them, and bash scripts/selftest/run-selftest.sh to verify it works. See mcp-server/README.md and docs/architecture/clone-mcp.md.

The clone is key-resilient: with no model key it still boots on the OpenCode Zen free floor, and MCP servers whose credentials are absent are disabled and reported (not left to fail at runtime).

The connector never reads or transmits secret values; it writes an empty ~/.env.workbench template for you to fill in.

Quick Start (≤ 5 minutes)

Fastest path: no box required — register the MCP server with npx -y @simonmak-ascent/opencode-workbench (config in Clone This Workbench); or provision a fresh box:

bash
# Create a new build boxgh SWAS create --repo simonmak-ascent/opencode-workbench --machine basicLinux32gb
# Wait for postCreate (3-5 min) — installs everything automatically# Then start coding:opencode

Workstation Governance

This workstation operates under a formal charter. Key principles:

  • Single Source of Truth: Runtime must match repository. Drift is a bug.
  • Secrets Never Touch Disk: All secrets flow through the build box Secrets.
  • Immutable History: Changelog is append-only. Every change is traceable.
  • Documentation Lives With Code: Docs describe the system as it is, not as imagined.

Read the full charter: docs/WORKBENCH_CHARTER.md

Backup Workflow

bash
# Master backup — full inventory, security scan, commit prepbash scripts/backup/run-master-backup.sh
# Quick backup — save state before risky operationsbash scripts/maintenance/sync-runtime-config.sh && \  git diff > /tmp/quick-backup-$(date +%Y%m%d).diff

Or use OpenCode prompts:

  • docs/prompts/RUN_MASTER_BACKUP.md — execute backup via AI
  • docs/prompts/QUICK_BACKUP.md — rapid state preservation

Recovery Workflow

Assume the build box is deleted. Only Git repo + build box Secrets survive.

bash
# 1. Create new build boxgh SWAS create --repo simonmak-ascent/opencode-workbench --machine basicLinux32gb
# 2. Wait for automation (3-5 min)
# 3. If needed (usually done by setup.sh):npx playwright install chromium# Vercel MCP uses VERCEL_ACCESS_TOKEN (token auth — no OAuth step)
# 4. Validate recoverybash scripts/recovery/validate-recovery.sh

describe_workbench

Workbench server info

Describe this MCP server from its bundled profile without contacting any target or making a network call: repository URL, the default component set, components grouped by tier (required/core/optional), and optional MCP add-ons. It takes no parameters, is always safe, and returns instantly. Use it first to resolve a component id for install_component/remove_component/update_component or to see available add-ons; use inspect_target for a machine's live state.

Takes no parameters.

inspect_target

Inspect a Linux target

Probe one Linux machine — this host (`local`) or a remote host over SSH (`ssh`) — and report its OS, kernel, architecture, package manager, Node/npm, OpenCode, Docker, and per-tool detection flags, plus the names (never values) of credentials present. Read-only: it runs one shell probe as the target user (over SSH when `mode:ssh`), installs nothing, writes nothing, contacts no external service, and can take a few seconds per hop. Parameter semantics: `target.mode` selects local vs ssh (default `local`); `target.host` is required only for ssh; `target.user` defaults to the ssh config/current user; `target.cwd` sets the directory for relative checks; `target.port`/`identityFile` pass straight to ssh. Use it to see what a clone would touch, then plan_clone to turn that into an ordered plan and apply_clone to perform it.

Parameterstargetrequired

plan_clone

Plan a Workbench clone

Return a read-only plan for a target: compare it against the Workbench profile and list each component as `install`, `present`, or `manual`, with the commands that would run. It still runs a detection probe on the target (same access as inspect_target) but clones nothing and writes nothing. Parameter semantics: `components` restricts the diff to those ids (default: required+core); `workspace` sets the expected profile path on the target (default `~/opencode-workbench`); `profileUrl` overrides the git remote. Use it to preview before apply_clone, which performs the changes.

ParametersdryRuntargetrequiredskipRepoworkspacecomponentsprofileUrl

apply_clone

Apply a Workbench clone

Apply the Workbench profile to a target: clone the repo and install missing components (OpenCode CLI, Node/pnpm, MCP servers, skills, plugins, optional Docker). It OVERWRITES `<home>/.config/opencode/opencode.json`, copies `AGENTS.md`, resets an existing profile repo to `origin/main`, and runs global installs that need write permission (plus SSH for `mode:ssh`) and can take minutes. Writes a names-only `~/.env.workbench` (mode 600); never secret values. Consent-gated and idempotent: without `confirm:true` it returns the plan and changes nothing. Parameter semantics: `components` defaults to required+core; `workspace` defaults to `~/opencode-workbench`; `skipRepo` skips the clone/update; `profileUrl` overrides the git remote; `dryRun` returns the plan. To preview only, use plan_clone.

ParametersdryRuntargetrequiredconfirmskipRepoworkspacecomponentsprofileUrl

verify_clone

Verify a Workbench clone

Re-check a target after a clone: return a per-component `present`/`missing` list plus whether `opencode.json` and `~/.env.workbench` exist. Read-only and idempotent: it runs a detection probe (SSH or local) and checks files, writing nothing. `target` selects the machine (`local` or SSH) and its `home` is where the `opencode.json` and `~/.env.workbench` checks run; `components` restricts the check to those ids (omit it to check every component, the default); `workspace` sets the profile path used by component checks. Use it after apply_clone and after component changes; for a pre-clone preview use plan_clone.

ParametersdryRuntargetrequiredskipRepoworkspacecomponentsprofileUrl

install_component

Install one Workbench component

Install a single Workbench component by id (e.g. `node`, `opencode`, `npm-mcps`, `skills`) on a target; `component` must be an id from describe_workbench. Overwrites that component's files when present (e.g. `skills`/`plugins` replace the copies under `<home>/.config/opencode`); global installs need write permission and can take minutes. Idempotent and consent-gated: without `confirm:true` it returns the plan. Parameter semantics: `component` is required; `workspace` defaults to `~/opencode-workbench`; `confirm` defaults to false (plan only). Use it for one targeted component; use apply_clone to install the full default set.

Parameterstargetrequiredconfirmcomponentrequiredworkspace

remove_component

Remove one Workbench component

Uninstall one Workbench component by id from a target — the inverse of install_component — for a bounded, documented subset with an automated uninstall (e.g. `opencode`, `pnpm`, `npm-mcps`, `skills`, `docker-containers`); `component` must be an id from describe_workbench. Idempotent: an already-absent component reports `absent`; a component with no automated uninstall (system packages such as git/curl/node) reports `manual`. Destructive and consent-gated: without `confirm:true` it returns a preview and changes nothing, and it deletes only that component's files — never `opencode.json` or the profile repo. Parameter semantics: `workspace` sets the profile path some removals need; `dryRun` reports without changing. Use it to tear down one component; for several, call it per id.

ParametersdryRuntargetrequiredconfirmcomponentrequiredworkspace

update_component

Update one Workbench component

Update one Workbench component in place by id: re-run its install script to fetch the current version (e.g. `opencode` re-runs the official installer; `npm-mcps` reinstalls the latest globals). It OVERWRITES the component's files, needs write permission, and can take minutes for global installs; the resolved version may change. Parameter semantics: `component` must be an id from describe_workbench; `workspace` defaults to `~/opencode-workbench`; `dryRun` previews; `confirm` defaults to false — set `confirm:true` to apply. For the whole profile use apply_clone.

ParametersdryRuntargetrequiredconfirmcomponentrequiredworkspace

list_required_credentials

List required credentials

List the credentials the profile references, which the target already provides, and how to acquire each missing one. Value-blind: it reads only whether each env var is set — no values, no network, no writes — via one read-only probe. Parameter semantics: `target` selects the machine (`local` or SSH) and its `home` sets the returned `template` path and the env file the presence check reads; there are no other parameters. Returns `present`/`missing` var-name arrays plus one guidance record per credential (`var`, `purpose`, `url`, `method`, `command`). Use it after plan_clone to see what would degrade; act on one credential with run_auth_flow.

Parameterstargetrequired

run_auth_flow

Acquire one credential (best-effort)

Return the acquisition plan for one credential on a target: the provider URL, the exact non-interactive command when one exists (e.g. `opencode auth login`, `opencode mcp auth vercel`, `gh auth login`), and whether it is already present. Read-only and value-blind: it emits guidance and re-checks presence with one read-only probe; it does not run the commands or handle secret values. Parameter semantics: `var` must be an env var name returned by list_required_credentials (unknown names error); `target` selects the machine and its `home` is where the value should be written. Use it for a single credential; it does not replace that listing.
