Switchboard MCP
When to Use
- When connecting Claude Desktop (or any other MCP-only chat host that has no shell/filesystem) to a Switchboard workspace.
- This skill is for filesystem hosts (Claude Code, Antigravity) that honor the MCP server's
instructions field and can read this SKILL.md. Claude Desktop ignores instructions and does not read skill files — its persona is delivered via tool descriptions + the opt-in switchboard_console prompt.
What It Is
A local stdio MCP server (@switchboard/mcp) that Claude Desktop launches as its own subprocess. The subprocess resolves 127.0.0.1 to the same box running VS Code and proxies every tool call to Switchboard's LocalApiServer HTTP surface. It is a stateless thin HTTP client — it holds no state, never touches kanban.db, and re-reads the ephemeral port on every call.
This is not the old in-extension MCP server (which was removed in commit 0b7ef13). That server was bundled into the extension build, held its own state, and was spawned/tracked by the extension. This server is external, stateless, and launched by the chat host.
Install
Claude Desktop (config snippet)
Add to claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/claude_desktop_config.json):
{
"mcpServers": {
"switchboard-mcp": {
"command": "npx",
"args": ["-y", "@switchboard/mcp"],
"env": { "SWITCHBOARD_WORKSPACE_ROOT": "/abs/path/to/workspace" }
}
}
}
Or use the in-extension Connect Claude Desktop button (Setup panel) to write this entry idempotently with the workspace root pre-filled.
From source
cd src/mcp && npm install && npm run build
node ./dist/index.js /abs/path/to/workspace
Configuration
SWITCHBOARD_WORKSPACE_ROOT (env) or first positional arg (required): absolute path to the workspace opened in VS Code with the Switchboard extension active.SWITCHBOARD_API_TOKEN (env, optional): bearer token. Leave unset for the default token-less localhost path. Sending a bearer header against a token-less server will 401.
Tools
Curated verbs: board_read, health_read (liveness + registered terminal agents), columns_read, plan_read, plan_create, plan_delete, plan_set_project, plan_set_complexity, card_move (move only — fires no agent), card_dispatch (ONE-call advance-and-dispatch via POST /kanban/dispatch; omit targetColumn for complexity auto-routing; DB-verified honest response), features_reconcile, orchestration_dispatch, worktree_list, worktree_cleanup, clickup_request, linear_request, catalog_read, plus a generic switchboard_request passthrough (method + path + body).
Persona
The management-console discipline (report-then-wait, no eager automation, no confirm gates, deletes execute immediately, never ask which project to pin) is baked into the tool descriptions. An opt-in switchboard_console prompt loads the full persona. The server instructions field is set for clients that honor it (Claude Code).
Naming Note
Always register the server under the key switchboard-mcp, never switchboard. The VS Code extension scrubs any switchboard-keyed MCP entry from .vscode/mcp.json, .cursor/mcp.json, .mcp.json, .kiro/settings/mcp.json, .gemini/settings.json, and ~/.codeium/windsurf/mcp_config.json on every activation (legacy cleanup). claude_desktop_config.json is not scrubbed, but use switchboard-mcp for consistency.
Requirements
- Node.js >= 18.
- Switchboard VS Code extension active with the target workspace open. If VS Code is closed, tool calls return a structured
SWITCHBOARD_NOT_RUNNING error and the process stays alive; reopening VS Code restores function without restarting the subprocess.
