memcastle¶

Local-first, always-on memory server for AI coding agents over MCP/HTTP

Running several AI coding agents side by side usually means each one gets its own, disconnected memory — or none at all. MemCastle is a single daemon per project ("palace") that all of them talk to over MCP or HTTP, so a mining run, a search, or a saved decision from one agent is immediately visible to every other agent and to the CLI.

See Architecture for the full design, and Development for the local workflow.

Installation¶
