dart_tooling_mcp_server

Experimental MCP server which exposes Dart development tool actions to clients.

Status

WIP

Using this package

To use this package, you will need to compile the bin/main.dart script to exe and use the compiled path as the command in your MCP server config.

dart compile exe bin/main.dart

With the example DashBot

After compiling the binary, you can run the example dash chat bot to interact with it, from the root of this package, after compiling the binary, run:

dart ../dart_mcp/example/dash_client.dart --server bin/main.exe

• If you want the client to invoke server tools without asking for human approval, add the --auto flag.
• If you want the client to output the raw LLM responses to the CLI instead of re-writing responses in the tone of Dash, add the --raw flag.

With the example WorkflowBot

After compiling the binary, you can run the example dash chat bot to interact with it, from the root of this package, after compiling the binary, run:

dart ../dart_mcp/example/workflow_client.dart --server bin/main.exe

With Cursor

Go to Cursor -> Settings -> Cursor Settings and select "MCP".

Then, click "Add new global MCP server". Put in the full path to the executable you created in the first step as the "command".

If you are directly editing your mcp.json file, it should look like this:

{
  "mcpServers": {
    "dart_mcp": {
      "command": "<path-to-compiled-exe>",
      "args": []
    }
  }
}

Each time you make changes to the server, you'll need to re-run dart compile exe bin/main.dart and reload the Cursor window (Developer: Reload Window from the Command Pallete) to see the changes.

Debugging MCP Servers

For local development, use the MCP Inspector.

1. Run the inspector with no arguments:

   npx @modelcontextprotocol/inspector

2. Open the MCP Inspector in the browser and enter the path to the server executable in the "Command" field (e.g. /Users/me/path/to/ai/pkgs/dart_tooling_mcp_server/bin/main.exe).

3. Click "Connect" to connect to the server and debug using the MCP Inspector.
