# OpenStinger

> OpenStinger v1.0: open-source MCP agent memory server for OpenClaw, Cursor, Claude Code, Hermes, and any MCP-compatible runtime.

OpenStinger is a self-hosted Model Context Protocol (MCP) memory server. Bi-temporal episodic memory on FalkorDB (graph + vectors), PostgreSQL audit trail, 32 MCP tools over SSE at http://localhost:8766/sse. Plug the same endpoint into any MCP client; memory is independent of the agent runtime.
