Dart MCP Server

Implementation Reference

• src/tools/pub.ts:12-28 (handler)

  The main handler function for the 'dart-package' tool. It executes the specified pub subcommand (like 'get', 'add', etc.) using the dart-executor utility and returns the output.

  export async function pub({ 
    command, 
    args = [], 
    workingDir 
  }: z.infer<typeof pubSchema>) {
    // If workingDir is provided, ensure it's absolute
    const absoluteWorkingDir = workingDir ? toAbsolutePath(workingDir) : workingDir;
    
    const { stdout, stderr } = await executeDartCommand('pub', [command, ...args], absoluteWorkingDir);
    
    return {
      content: [
        { type: "text" as const, text: stdout || stderr }
      ],
      isError: !!stderr
    };
  }

• src/tools/pub.ts:5-10 (schema)

  Zod schema defining the input parameters for the 'dart-package' tool: command (pub subcommand), optional args, and optional working directory.

  export const pubSchema = z.object({
    command: z.enum(['get', 'upgrade', 'outdated', 'add', 'remove', 'publish', 'deps', 'downgrade', 'cache', 'run', 'global'])
      .describe('Pub subcommand to execute'),
    args: z.array(z.string()).optional().describe('Arguments for the pub subcommand'),
    workingDir: z.string().optional().describe('Working directory for the command')
  });

• src/index.ts:40-40 (registration)

  Registration of the 'dart-package' tool in the MCP server, linking the name to pubSchema and the pub handler function.

  server.tool('dart-package', pubSchema.shape, pub);
