SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps developers design and implement high-quality MCP servers that let LLMs interact reliably with external APIs and services. It reduces the guesswork around tool design, protocol choices, schema definition, error handling, testing, and evaluation.

Core Features & Use Cases

  • End-to-end MCP server guidance: Covers research, planning, implementation, review, testing, and evaluation for MCP servers.
  • Language-specific implementation support: Provides direction for both TypeScript and Python MCP development, including SDK usage, schema patterns, and transport recommendations.
  • Tool design best practices: Emphasizes discoverable naming, comprehensive API coverage, structured outputs, pagination, annotations, and actionable error messages.
  • Evaluation workflow: Helps create realistic read-only benchmark questions to verify that an LLM can use the server effectively in real tasks.
  • Use case: Build an MCP server for a SaaS platform such as GitHub, Stripe, or an internal API so agents can search data, retrieve records, and perform supported actions through well-structured tools.

Quick Start

Ask the agent to use the mcp-builder skill to plan and implement an MCP server for a specific API in TypeScript or Python, then generate a testing and evaluation checklist.

FAQPage Schema
How do I build an MCP server for an external API?

To build an MCP server for an external API, you define tools, transports, schemas, and error handling using the TypeScript or Python SDK, ensuring language models can reliably interact with the service. This covers planning, implementation, review, testing, and evaluation workflows.

What is Model Context Protocol tool design?

Model Context Protocol tool design involves creating discoverable naming, comprehensive API coverage, structured outputs, pagination, and actionable error messages so LLMs can effectively use external services. It ensures agents can search data and perform supported actions reliably.

Can I implement MCP servers in both Python and TypeScript?

Yes, you can implement MCP servers in both Python and TypeScript. The implementation process provides specific SDK usage direction, schema patterns, and transport recommendations tailored for both languages to connect language models to external APIs.

How do I evaluate if an LLM can use my MCP server effectively?

To evaluate if an LLM can use your MCP server effectively, you create realistic read-only benchmark questions that verify the agent can successfully interact with your defined tools. This evaluation workflow tests whether the server handles tasks as expected in real scenarios.

What is the best way to handle errors in Model Context Protocol servers?

The best way to handle errors in Model Context Protocol servers is to provide actionable error messages that guide the LLM toward resolution. Structured tool outputs and comprehensive API coverage ensure the agent receives clear, usable feedback during interactions.

Do I need specific SDKs to create a Model Context Protocol server?

Yes, you need either the TypeScript or Python SDK to create a Model Context Protocol server. These SDKs provide the necessary framework for defining schemas, configuring transports, and implementing the protocol-aware architecture required for LLM integration.
