Build an MCP server using Python FastMCP or Node/TypeScript SDKs by defining tool schemas, handling errors, and formatting responses. This skill provides scripts and references to guide development of robust, LLM-consumable APIs.

The Model Context Protocol (MCP) is a standard for connecting LLMs to external services. You need it when integrating internal company APIs or third-party services so LLMs can programmatically access external functionality to complete complex tasks.

Yes, MCP server development supports both Python using FastMCP and Node/TypeScript using official SDKs. This skill covers tool design, response formatting, pagination, character limits, and security for both environments.

Design MCP server tools by following best practices for naming, defining input/output schemas, handling errors, and documenting functionality. Ensure responses are properly formatted with pagination and character limits for LLM consumption.

Evaluate your MCP server by creating rigorous evaluations to test its effectiveness with LLMs. This skill provides an evaluation framework to ensure your tools perform correctly when accessed programmatically by language models.

MCP server development requires following security best practices when exposing internal APIs or third-party services to LLMs. This skill covers security alongside response formatting, pagination, and character limits to ensure robust API design.
