What is the LanceDB (Serverless Vector DB) MCP Server?
Connect your LanceDB Cloud account to any AI agent and take full control of your serverless vector storage and RAG infrastructure through natural conversation.
What you can do
- Vector Orchestration — List all vectorized tables and retrieve precise schema metadata, including tensor dimensions and vector topologies directly from your agent
- Similarity Search — Execute highly-optimized KNN (K-Nearest Neighbor) lookups to retrieve semantically related rows based on embedding array similarity
- Dynamic Ingestion — Insert new structured row payloads and vectors into existing tables, updating the underlying ANN index in real-time
- Table Management — Provision new columnar vector tables declaring specific Apache Arrow schemas and multi-dimensional layouts required for AI workloads
- Database Audit — Discover active table boundaries and verify storage configurations assigned to your serverless database instance securely
- Resource Cleanup — Irreversibly delete entire vector tables to maintain a clean and optimized data environment for your AI applications
How it works
- Subscribe to this server
- Enter your LanceDB API URL, API Key, and Database Name
- Start managing your vector storage from Claude, Cursor, or any MCP-compatible client
Who is this for?
- RAG Developers — perform semantic searches and verify document retrieval results through natural conversation without manual Python scripts
- Data Engineers — provision and manage vector tables with strict Apache Arrow schemas to power multi-modal AI applications
- AI Architects — monitor vector topologies and audit storage usage across multiple serverless database instances efficiently

Frequently asked questions
Can I perform a semantic similarity search using my agent?
Yes. Use the vector_search tool by providing the target Table name and a JSON array of floating-point numbers representing your query embedding. Your agent will return the k-nearest rows from LanceDB based on semantic similarity.
How do I create a new table with a specific Apache Arrow schema?
The create_table tool allows your agent to initialize a new columnar vector table. You just need to provide the desired Table name and a valid Apache Arrow schema mapping in JSON format defining dimensions and scalar fields.
Can my agent insert new embeddings directly into a LanceDB table?
Absolutely. Use the insert_rows tool to persist new data rows containing native embeddings and arbitrary JSON metadata. Your agent will handle the payload delivery, and LanceDB will automatically update its ANN index.
How does LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
