MCP server for interacting with LanceDB database
Lance MCP MCP server exists for a simple reason — assistants are far more useful when they can act on Lance MCP directly instead of describing what you should do. MCP server for interacting with LanceDB database.
A Model Context Protocol (MCP) server that enables LLMs to interact directly the documents that they have on-disk through agentic RAG and hybrid search in LanceDB. Ask LLMs questions about the dataset as a whole or about specific documents.
The server ships on npm as @modelcontextprotocol/inspector, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.
Once Lance MCP is connected, these are the calls the assistant has available:
catalog_search — Search for relevant documents in the catalogchunks_search — Find relevant chunks based on a specific document from the catalogall_chunks_search — Find relevant chunks from all known documentsPrerequisites — The Prerequisites tool exposed by this serverDemo — The Demo tool exposed by this serverCatalog — The Catalog tool exposed by this serverChunks — The Chunks tool exposed by this serverollama pull snowflake-arctic-embed2 - ollama pull llama3.1:8bThis sits in the database access group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Lance MCP's toolset — catalog_search, chunks_search, all_chunks_search and 4 more — is a fair guide to whether it matches your workflow. It is maintained by adiom-data; worth a glance at recent repository activity before you build anything load-bearing on it.
