Delimit MCP Server

The merge gate for AI-written code, with signed, replayable attestation. Wrap any AI coding assistant (Claude Code, Codex, Cursor, Gemini CLI) with a governance chain that runs your gates, records what changed, and signs a replayable receipt for every merge. It runs locally over stdio via the published package.

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.

01 · Install Delimit

before you install - you'll need

Set DELIMIT_DISABLE_CLOUD_SYNC before connecting.

Claude Code

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

Claude Desktop / Cursor / VS Code - add to config

{
  "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

What is Delimit?

Is Delimit still maintained?

Yes - as of 2026-09-18, its last commit was 2026-09-16 and it shipped 10+ releases in the last 90 days. We re-verify nightly.

How do I install Delimit?

Run `npx -y delimit-cli`. The README documents one environment variable (DELIMIT_DISABLE_CLOUD_SYNC) to set first. Set DELIMIT_DISABLE_CLOUD_SYNC before connecting. You can also paste the ready-made client config above.

Does Delimit run locally?

Yes - it's a stdio server: it runs on your machine (via npx) with your user's permissions. Your data stays local unless the server itself calls external APIs.
