cursor-mcp-bridge

MCP server that lets any agent or MCP host delegate to the Cursor CLI agent (agent -p) running headless. Cursor is the cheap/fast worker in the fleet — use it for routine work and to map unfamiliar projects without burning your own context.

Mirrors the ergonomics of agy-bridge: every tool takes an optional model and effort, returns a session_id, and supports follow_up. Default model is auto (Cursor picks the cheapest adequate model).

Tools

Every tool accepts: cwd, model (default auto), effort (applied only to parameterized models; auto ignores it).

Related MCP server: delegations-mcp

Requirements

• Node ≥ 18

• Cursor CLI installed as agent and authenticated (agent login).

Install

git clone https://github.com/JaimeJunr/cursor-mcp-bridge.git
cd cursor-mcp-bridge
npm install
npm run build

Register in an MCP host

Claude Code:

claude mcp add cursor-bridge -s user -- node /abs/path/to/cursor-mcp-bridge/dist/index.js

Any host — add to its mcp.json:

{
  "mcpServers": {
    "cursor-bridge": {
      "command": "node",
      "args": ["/abs/path/to/cursor-mcp-bridge/dist/index.js"]
    }
  }
}

Configuration (env)

Security: delegate can edit files and (with CURSOR_BRIDGE_FORCE) run shell autonomously. discovery and analyze_files run in read-only modes (plan / ask).

Develop

npm test       # vitest — unit tests for model resolution / arg building
npm run dev    # run from source via tsx
