Main
Keep the setup minimal: follow the README’s 3-line path (install → index → serve-mcp) before tuning workspaces and tool permissions.
Run indexing per workspace so the agent can switch contexts cleanly; the README shows passing
--workspacewhen serving MCP.Use this when you want local retrieval without embedding APIs: README emphasizes SQLite FTS5 + engineered ranking and includes benchmark numbers.
Source-backed notes
- README opens with a 3-command setup:
pip install open-db[cli],opendb index, andopendb serve-mcp. - README states the MCP server exposes 12 tools and provides config examples for clients (Claude Code/Cursor and multiple agent SDKs).
- README reports LongMemEval numbers (93.6% E2E accuracy; 500 questions) and highlights a SQLite-only retrieval stack.
FAQ
- Do I need a vector database?: No — README emphasizes SQLite-only retrieval (FTS5) with engineered ranking.
- How do I expose tools to my agent?: Run
opendb serve-mcpand wire it as an stdio MCP server (README shows multiple client examples). - Can I index multiple workspaces?: Yes — README describes indexing and serving with an explicit
--workspacepath.
