Hybrid trigram+vector search, full-sutta fetch with cross-reference URLs (SuttaCentral + 84000.org), segment-aligned translation comparison, and Pāli word lookup against the P. A. Payutto dictionary. Free, non-commercial — offered as Dhamma Dāna. Hosted at https://tripitaka-mcp.com or self-host via Docker.

Penfield MCP

Knowledge & Memory

Penfield: persistent memory with hybrid search (BM25 + vector + graph), 24 relationship types for knowledge graphs, context checkpoints for cognitive handoff, artifact storage, and personality system. Works across Claude, Cursor, Windsurf, and any MCP client.
