Radicle + GitHub MCP Server

Instructions

Push changes to the Radicle network.

Args:
    repository_path: Path to the repository (default: current directory)

Implementation Reference

• src/radicle_mcp/server.py:153-167 (handler)

  The primary handler function for the 'rad_push' tool. It is decorated with @mcp.tool() which registers it with the MCP server. Executes 'rad push' command in the given repository path using the run_rad_command helper, returning success or error message.

  @mcp.tool()
  async def rad_push(repository_path: str = ".") -> str:
      """
      Push changes to the Radicle network.
      
      Args:
          repository_path: Path to the repository (default: current directory)
      """
      result = await run_rad_command(["rad", "push"], cwd=repository_path)
      
      if result["success"]:
          return f"✅ Successfully pushed changes\n{result['stdout']}"
      else:
          return f"❌ Failed to push changes: {result['stderr']}"

• src/radicle_mcp/server.py:37-85 (helper)

  Shared helper function used by rad_push (and other tools) to execute 'rad' CLI commands asynchronously, capturing stdout, stderr, return code, and handling errors.

  async def run_rad_command(command: List[str], cwd: Optional[str] = None) -> Dict[str, Any]:
      """
