Baton

Local MCP server for Baton: edit git-native API requests, collections, environments and scripts.

Documentation

Baton — MCP setup

Let your AI assistant work in a Baton workspace. Baton is a git-native API client (a Postman alternative): requests, collections and environments are plain YAML files in a repository you own. The MCP server runs locally, edits those files the same way the app does, and every change shows up in the app instantly and goes through git review like any other change.

Server: baton
Transport: stdio (local process)
Package: @dudko.dev/baton-mcp — Node.js 24+
Auth: none — it runs locally with your user's permissions; secrets never pass through it.

What you can do

By default the assistant can read and write the workspace but not send requests:

Tool	What it does
`workspace_info`	Orientation: name, settings, environments, collection tree.
`list_requests`	Requests with method, URL and tags.
`get_request`	A parsed request plus its raw YAML — secrets appear as references only.
`upsert_request`	Write a request as deterministic YAML.
`move_request`	Move or rename a request, keeping its id.
`delete_request`	Delete a request.
`upsert_collection`	Create or update a collection or folder.
`list_environments`	Environments, with secret names only.
`upsert_environment`	Write an environment (secret names only).
`get_script / upsert_script`	Read and write pre-request and test scripts.
`run_request / run_collection`	Execute a request or a collection — only with `--allow-run`.

Install in Claude Code (plugin)

/plugin marketplace add dudko-dev/baton-mcp-setup
/plugin install baton@baton
/reload-plugins

The plugin starts the server in the current project directory, so open Claude Code in (or under) your Baton workspace. To point it elsewhere, or to let the assistant execute requests, add the server by hand instead (below) with --workspace <dir> and/or --allow-run.

Prefer not to use the marketplace? Add the server directly:
claude mcp add baton -- npx -y @dudko.dev/baton-mcp --workspace /path/to/workspace

Connect from other clients

Claude Desktop

claude_desktop_config.json (Settings → Developer → Edit Config):

{
  "mcpServers": {
    "baton": {
      "command": "npx",
      "args": [
        "-y",
        "@dudko.dev/baton-mcp"
      ]
    }
  }
}

Cursor

~/.cursor/mcp.json or .cursor/mcp.json:

{
  "mcpServers": {
    "baton": {
      "command": "npx",
      "args": [
        "-y",
        "@dudko.dev/baton-mcp"
      ]
    }
  }
}

VS Code (GitHub Copilot / MCP) and other clients

{
  "servers": {
    "baton": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@dudko.dev/baton-mcp"
      ]
    }
  }
}

Safety

Running requests is off by default. Add --allow-run to the args only when you want the assistant to fire requests — editing files should never silently send traffic.
Secrets stay out of the workspace. The server reads and writes secret names and {{secret:name}} references only; a plaintext value where a reference belongs is refused.
The server never touches git. Commits stay yours.

Flag	Meaning
`--workspace <dir>`	Workspace folder (default: current directory).
`--allow-run`	Let the agent execute requests. Off by default.

Troubleshooting

"not a Baton workspace" / the client says "Connection closed" — the server exits at start when the folder has no baton.yaml. Open Claude Code in your workspace, or add the server by hand with --workspace /path/to/workspace.
run_request refuses — add --allow-run.
npm warn EBADENGINE … required: { node: '>=24' }, then nothing — the server needs Node.js 24+; node --version in the shell your client starts.
