Bazel MCP Server

This project provides a Model Context Protocol (MCP) server that exposes tools for interacting with Bazel projects.

Status: 🚧 Under Active Development 🚧

Features and interfaces may change.

Features

This server currently provides the following tools:

• build: Builds a specified Bazel target.
• deps: Finds the dependencies of a given Bazel target, with an optional depth parameter.
• rdeps (Reverse Dependencies): Finds all Bazel targets that depend on a given target or file path, with an optional depth parameter.
• sources: Finds the direct source files associated with a given Bazel target.
• test: Runs tests for a specified Bazel target.

Usage with Claude Desktop

This server is designed to be used as a tool provider for applications like the Claude Desktop app.

1. Installation

Install the server using go install:

# Ensure your Go environment is set up (GOPATH, GOBIN, etc.)
go install github.com/aaomidi/mcp-bazel@latest

This command compiles and installs the mcp-bazel binary. By default, it's placed in your $GOPATH/bin directory or $HOME/go/bin if GOPATH is not set. Make sure this location is in your system's PATH or note the full path to the binary for the next step.

2. Configuration

Add the following configuration to your Claude Desktop settings file (claude_desktop_config.json). You can usually find this file via the app's settings menu ("Open Config Folder").

Modify the "command" path to point to the actual location where go install placed the mcp-bazel binary on your system.

{
  "mcpServers": {
    "mcp-bazel": {
      "command": "/path/to/your/go/bin/mcp-bazel"
    }
  }
}

3. Restart Claude Desktop

After saving the configuration file, restart the Claude Desktop app. The Bazel tools should now be available.
