Limpet MCP Server
small shell. long memory. Memory for AI coding agents that goes stale when your code does. Everything your agent learns about a codebase (decisions, verified facts, failed approaches, gotchas) survives every session, anchored to the actual code it describes, and flips to stale with the reason attached the moment that code moves on. One Rust binary, one SQLite file, standard MCP, zero network calls.
People who work with developer tools, tree sitter and ai memory and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Rust.
