mcp-lance-db: A LanceDB MCP server 工具

Adds a new memory to the vector database

Retrieves semantically similar memories

概览

What is mcp-lance-db?

mcp-lance-db is a Model Context Protocol server that stores and retrieves memories in the LanceDB vector database. It acts as a semantic memory layer for LLM applications, allowing text to be stored with vector embeddings for later retrieval.

How to use mcp-lance-db?

Configure it in your MCP client (e.g., Claude Desktop) by adding the command uvx mcp-lance-db to the client’s config file. For Claude Desktop, the config file is claude_desktop_config.json. The server then exposes two tools: add-memory and search-memories.

Key features of mcp-lance-db

Adds new text memories with vector embeddings
Searches memories by semantic similarity
Configurable result limit (default 5)
Embeds using sentence-transformers (BAAI/bge-small-en-v1.5)
Stores data locally in a LanceDB database
Notifies clients of resource changes

Use cases of mcp-lance-db

Provide a persistent semantic memory for conversational AI assistants
Enable retrieval of past context or facts by meaning, not keywords
Build a lightweight personal knowledge base for LLM tools
Store and recall user preferences or session history semantically
