Verified project record

modelcontextprotocol/servers

A collection of official reference implementations for the Model Context Protocol, managed by the MCP steering group. Developers can use these servers to learn MCP features, evaluate official SDKs, and build their own custom servers.

Project overview

Project type: MCP · AI Agent
Use cases: Automation
Deployment: Node.js / npm
License: License pending

Best for

Developers and AI engineers seeking educational examples of MCP servers and official SDK usage.

Key capabilities

A reference and test server exposing prompts, resources, and tools.
Fetches web content and converts it for LLM usage.
Provides secure file operations with configurable access controls.
Tools to read, search, and manipulate Git repositories.
A knowledge graph-based persistent memory system.
Enables dynamic and reflective problem-solving through thought sequences.
Provides time and timezone conversion capabilities.

Limitations and risks

The servers are intended as educational examples and reference implementations, not as production-ready solutions.
Developers must evaluate their own security requirements and implement appropriate safeguards based on their specific threat model and use case.

Getting started

Install npx or uvx, then run a server directly using a command such as npx -y @modelcontextprotocol/server-memory. No complex setup is required.
