# mcp-memory-libsql A high-performance, persistent memory system for the Model Context Protocol (MCP) powered by libSQL. This server provides vector search capabilities and efficient knowledge storage using libSQL as the backing store. ## Features - High-performance vector search using libSQL - Persistent storage of entities and relations - Semantic search capabilities - Knowledge graph management - Compatible with local and remote libSQL databases - Secure token-based authentication for remote databases ## Configuration This server is designed to be used as part of an MCP configuration. Here are examples for different environments: ### Cline Configuration Add this to your Cline MCP settings: \`\`\`json \{ "mcpServers": \{ "mcp-memory-libsql": \{ "command": "npx", "args": ["-y", "mcp-memory-libsql"], "env": \{ "LIBSQL_URL": "file:/path/to/your/database.db" \} \} \} \} \`\`\` ### Claude Desktop with WSL Configuration For a detailed guide on setting up this server with Claude Desktop in WSL, see [Getting MCP Server Working with Claude Desktop in WSL](https://scottspence.com/posts/getting-mcp-server-working-with-claude-desktop-in-wsl). Add this to your Claude Desktop configuration for WSL environments: \`\`\`json \{ "mcpServers": \{ "mcp-memory-libsql": \{ "command": "wsl.exe", "args": [ "bash", "-c", "source ~/.nvm/nvm.sh && LIBSQL_URL=file:/path/to/database.db /home/username/.nvm/versions/node/v20.12.1/bin/npx mcp-memory-libsql" ] \} \} \} \`\`\` ### Database Configuration The server supports both local SQLite and remote libSQL databases through the LIBSQL_URL environment variable: For local SQLite databases: \`\`\`json \{ "env": \{ "LIBSQL_URL": "file:/path/to/database.db" \} \} \`\`\` For remote libSQL databases (e.g., Turso): \`\`\`json \{ "env": \{ "LIBSQL_URL": "libsql://your-database.turso.io", "LIBSQL_AUTH_TOKEN": "your-auth-token" \} \} \`\`\` Note: When using WSL, ensure the database path uses the Linux filesystem format (e.g., \`/home/username/...\`) rather than Windows format. By default, if no URL is provided, it will use \`file:/memory-tool.db\` in the current directory. ## API The server implements the standard MCP memory interface with additional vector search capabilities: - Entity Management - Create/Update entities with embeddings - Delete entities - Search entities by similarity - Relation Management - Create relations between entities - Delete relations - Query related entities ## Architecture The server uses a libSQL database with the following schema: - Entities table: Stores entity information and embeddings - Relations table: Stores relationships between entities - Vector search capabilities implemented using libSQL's built-in vector operations ## Development ### Publishing Due to npm 2FA requirements, publishing needs to be done manually: 1. Create a changeset (documents your changes): \`\`\`bash pnpm changeset \`\`\` 2. Version the package (updates version and CHANGELOG): \`\`\`bash pnpm changeset version \`\`\` 3. Publish to npm (will prompt for 2FA code): \`\`\`bash pnpm release \`\`\` ## Contributing Contributions are welcome!
