Servers

What is Servers?

Servers is a curated collection of reference implementations for the Model Context Protocol (MCP). It is maintained by the MCP steering group and provides educational examples—using the official MCP SDKs—to demonstrate how to give LLMs secure, controlled access to tools and data sources.

How to use Servers?

TypeScript-based servers can be run directly with npx -y @modelcontextprotocol/server-<name>, while Python-based servers work with uvx mcp-server-<name> or pip install mcp-server-<name> followed by python -m mcp_server_<name>. Servers are typically configured inside an MCP client (e.g., Claude Desktop) by adding a JSON entry under mcpServers that specifies the command and arguments.

Key features of Servers

• Reference implementations of the Model Context Protocol
• Built with official MCP SDKs (C#, Go, Java, Kotlin, PHP, Python, Ruby, Rust, Swift, TypeScript)
• Demonstrates prompts, resources, tools, and knowledge graph memory
• Supports secure file operations, Git manipulation, and web fetching
• Time and timezone conversion capabilities
• Not intended for production use; educational examples for developers

Use cases of Servers

• Learning how to implement MCP servers using official SDKs
• Testing and prototyping MCP interactions with a client
• Exploring features like persistent memory, sequential thinking, and file system access
• Building foundational knowledge for creating custom MCP servers

FAQ from Servers

What is the purpose of these servers?

They are educational reference implementations designed to demonstrate MCP features and SDK usage, not production-ready solutions.

Are these servers safe to use in production?

No. The README explicitly warns they are not production-ready and urges developers to evaluate their own security requirements and implement appropriate safeguards.

How do I run a server from this repository?

TypeScript servers: use npx -y @modelcontextprotocol/server-<name>. Python servers: use uvx mcp-server-<name> or pip install mcp-server-<name> then python -m mcp_server_<name>.

Where can I find more MCP servers beyond these reference implementations?

A list of published community servers is available on the official MCP Registry at https://registry.modelcontextprotocol.io/.

What SDKs are used to implement these servers?

The servers are built with the official MCP SDKs for C#, Go, Java, Kotlin, PHP, Python, Ruby, Rust, Swift, and TypeScript.
