Delimit MCP Server

Keep the state. Change the model. Keep decisions, records, and handoffs across Claude Code, Codex, Cursor, Antigravity, GitHub Copilot, and Muse. Bring configured models together for hard calls. For code repositories, Delimit also offers a merge gate and local signed attestations.

People who work with api governance, breaking changes and openapi and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

The README does not document required environment variables for a basic install.

Claude Code

claude mcp add delimit-ai-delimit -- npx -y delimit-cli

{
  "mcpServers": {
    "delimit-ai-delimit": {
      "command": "npx",
      "args": [
        "-y",
        "delimit-cli"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key
