Overview

mcp-lance-db is a Model Context Protocol (MCP) server designed for LanceDB, an embedded vector database that facilitates the integration of LLM applications with external data sources and tools.

To use mcp-lance-db, configure your environment to point to the LanceDB database and run the server using the provided command. You can add memories and search for semantically similar memories through the implemented tools.

  • Adds and retrieves memories with vector embeddings. - Implements two main tools: add-memory and search-memories. - Configurable database path and collection name.
  1. Storing and retrieving contextual information for AI applications.
  2. Enhancing chat interfaces with memory capabilities.
  3. Building custom AI workflows that require semantic memory.

Cursor

Add this to your .cursor/mcp.json file in your project root, then restart Cursor.

.cursor/mcp.json

{
  "mcpServers": {
    "mcp-server-lancedb-kyryl-opens-ml": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-mcp-server-lancedb-kyryl-opens-ml"
      ]
    }
  }
}

{
  "mcpServers": {
    "mcp-server-lancedb-kyryl-opens-ml": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-mcp-server-lancedb-kyryl-opens-ml"
      ]
    }
  }
}

Claude Code

Add this to your project's .mcp.json file. Claude Code will detect it automatically.

.mcp.json (project root)

{
  "mcpServers": {
    "mcp-server-lancedb-kyryl-opens-ml": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-mcp-server-lancedb-kyryl-opens-ml"
      ]
    }
  }
}

VS Code (Copilot)

Add this to your .vscode/mcp.json file. Requires the GitHub Copilot extension with MCP support enabled.

.vscode/mcp.json

{
  "servers": {
    "mcp-server-lancedb-kyryl-opens-ml": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-mcp-server-lancedb-kyryl-opens-ml"
      ]
    }
  }
}

Windsurf

Add this to your Windsurf MCP config file, then restart Windsurf.

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "mcp-server-lancedb-kyryl-opens-ml": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-mcp-server-lancedb-kyryl-opens-ml"
      ]
    }
  }
}

Cline
