Yantrikdb Mcp
Gives Claude persistent memory across sessions using semantic search, knowledge graphs, and contradiction detection. Ships 16 tools including remember, recall, forget, and correct, plus specialized operations for temporal queries, procedural learning, and personality tracking. Runs three ways: embedded SQLite for single users, stateless client against a YantrikDB HTTP cluster for shared setups, or as an SSE server. Stores everything locally by default at ~/.yantrikdb/memory.db with no telemetry. The benchmarks are worth reading: at 5,000 memories it uses 53 tokens per query versus 101,739 for file-based approaches, and precision improves as the dataset grows. Reach for this when you need Claude to remember decisions, detect conflicting facts, or build up domain knowledge without stuffing context windows.

YantrikDB MCP Server
YantrikDB — Cognitive memory for AI agents. Persistent semantic recall, knowledge graph, contradiction detection, and procedural learning. Ships as embeddable engine, network database, or MCP server.
Works with Claude Code, Cursor, Windsurf, Hermes Agent, Prime Agent, and any MCP-compatible client. Ships a portable Agent Skills skill — skills/persistent-memory — that teaches any compliant harness the memory golden path.
