What problem does it solve?
Enable developers to design and implement MCP (Model Context Protocol) servers that let LLMs interact reliably with external APIs and services, reducing ambiguity and integration friction when exposing tooling to agents.
Core Features & Use Cases
- Design Guidance: Principles for API coverage vs. workflow tools, tool naming, and context management to improve discoverability and agent usability.
- Implementation Patterns: Language-specific instructions for Python (FastMCP) and Node/TypeScript (MCP SDK), including input validation, structured outputs, transports (stdio, streamable HTTP), and example project layouts.
- Quality & Evaluation: Testing checklists, evaluation creation guidelines, and an evaluation harness for measuring how well LLMs can use the server.
- Use Case: Ship an MCP server that exposes well-documented, paginated read-only tools for an internal API so agents can answer multi-step queries reliably.
Quick Start
Create a production MCP server using the provided guides to register tools with strict schemas, clear descriptions, and proper transport configuration.
