Reference implementations of Model Context Protocol (MCP) servers demonstrating how AI applications can securely access tools and data sources. Includes example servers for file systems, web fetching, Git, memory, and more across multiple languages.
Use cases
- connect an LLM to a local file system for reading and writing documents
- enable an AI assistant to fetch and summarize web content
- provide a Git server interface for AI-driven code analysis
- expose a persistent memory graph for long‑term context in AI agents
- allow AI models to perform time zone conversions and scheduling
- build custom MCP servers to integrate proprietary APIs with LLMs
When to choose
- You need a reference starting point for building your own MCP server
- You want multi‑language examples of how to expose tools to LLMs
- Your project requires secure, standardized access for AI agents to external resources
- You are developing an AI‑driven application that needs to call tools via a protocol
When to avoid
- You need a production‑grade, out‑of‑the‑box server with built‑in security hardening
- Your use case does not involve LLMs or AI agents
- You require a single‑language solution without cross‑language SDKs
