Best for
Developers building their own servers who need to learn from educational examples demonstrating official SDKs.
Key capabilities
A reference and test server with prompts, resources, and tools.
Web content fetching and conversion for efficient LLM usage.
Secure file operations with configurable access controls.
Tools to read, search, and manipulate Git repositories.
Knowledge graph-based persistent memory system.
Dynamic and reflective problem-solving through thought sequences.
Time and timezone conversion capabilities.
Limitations and risks
These 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
Installation difficulty is rated easy. Users can install npx or uvx and run a server directly, for example by executing `npx -y @modelcontextprotocol/server-memory`.
