Avian Suite MCP Server

Safe write access for AI agents. Stellar Jay is where your agents keep business data. Every change is kept, attributed to the agent that made it, and can be undone. Think of it as Git for your business data. It is available as a remote MCP endpoint.

Teams that work with agent memory, append only and audit trail and want a hosted endpoint instead of running a local process. The project is written in Go.
