3.2.1 Mcp Server Builder

Use this skill when tasked with extending the agent's capabilities by building a new Model Context Protocol (MCP) server.

1. Project Scaffolding

  • Initialization: Scaffold standard Node.js or Python projects configured for MCP.
  • Dependencies: Install the official @modelcontextprotocol/sdk or the Python equivalent.

2. Server Architecture

  • Tool Definitions: Define strict JSON schema definitions for all resources and tools the MCP server exposes.
  • Protocol Handlers: Map incoming JSON-RPC calls from the MCP client to the private API endpoints.

3. Security & Context

  • API Keys: Never hardcode private API keys in the MCP server. Read them cleanly from the local environment or .env.
  • Error Handling: Return descriptive error contexts back over the MCP protocol so the agent can self-correct when API calls fail.
