# Axonio

> Axonio is an open-source memory engine and hosted MCP server that gives AI agents and robots persistent, branchable memory: hybrid vector and knowledge-graph retrieval with Git-style fork, diff and merge.

Axonio was formerly named ClawDB; the open-source SDK packages keep that name (npm `@clawdb/sdk`, PyPI `clawdb`, MCP `@clawdb/mcp-adapter`). Hosted MCP endpoint: https://api.axonio.xyz/api/v1/mcp.
