Model Context Protocol Servers
The Model Context Protocol Servers repository provides official reference implementations of MCP servers that demonstrate how to connect large language models to tools and data sources. Maintained by the MCP steering group, it includes educational examples like filesystem access, Git operations, web fetching, and knowledge graph memory systems. These servers showcase best practices for building MCP integrations using the official SDKs across ten programming languages. Developers use these as templates and learning resources when creating their own MCP servers.

servers — FAQ
What are Model Context Protocol reference servers?+
These are official example implementations of MCP servers maintained by the Model Context Protocol steering group. They demonstrate how to build MCP integrations and are intended for educational purposes, not production deployment without additional security review.
How do I install an MCP server from this repository?+
TypeScript servers can be run directly with npx (e.g., 'npx -y @modelcontextprotocol/server-memory'). Python servers use uvx (e.g., 'uvx mcp-server-git') or pip. You then configure them in your MCP client like Claude Desktop.
Which AI clients work with these MCP servers?+
These servers work with any MCP-compatible client, with Claude Desktop being the primary example shown in the documentation. Configure the server command and arguments in your client's MCP settings JSON file.
Do I need API keys to use these reference servers?+
Most reference servers like Filesystem, Git, Memory, and Time require no API keys. They operate on local resources or built-in capabilities without external service authentication.
Are these MCP servers free to use?+
Yes, all reference servers are open source and free to use under the Apache License 2.0 for new contributions and MIT for existing code. They are maintained by Anthropic and the community.
Can I use these servers in production applications?+
These are reference implementations meant for education and development examples. Developers should evaluate security requirements and implement appropriate safeguards for their specific use case before production deployment.
How do I install servers?+
Open the source repository on GitHub and follow its README. servers is a mcp server — MCP Agents Market links you directly to the official repo.
Is servers free?+
servers is an open-source project hosted on GitHub. Check the repository for its license and any usage requirements.
