Memory Rs MCP Server
Local-first MCP memory server in pure Rust. Persistent, versioned, queryable memory for AI agents - owned by the user, not by a platform. Its 16 documented tools cluster into memory, sync.
People who work with fts5, local first and memory and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Rust.

02 · What Memory Rs can do
Prose above is summarized from the project's README and registry record - no invented capabilities.
What you can build
With this server connected, an agent can read a category (optional field filtering), replace or merge-patch a category, delete a category (backup created first), and compare local vs remote manifest: push/pull/conflict sets.
