MCP plugin

Governed memory for any MCP client.

One small server adds memory to Claude Code, Cursor, Codex, Cline, and anything that speaks MCP. The agent sees exactly two tools — recall and remember; everything governed stays server-side.

Why it's small[1 / 3]

Two tools, not twenty.

A minimal surface keeps the agent's context clean — admin lives behind the server, not in the prompt.

  • Exactly two tools ★

    recall + remember — about 200 tokens on the agent's context.

  • Admin stays server-side

    Buckets, promotion, identity, audit never touch the agent.

  • Subagents inherit

    Wire the parent once; spawned helpers get scoped memory automatically.

  • Any MCP client

    Claude Code, Cursor, Codex, Cline — one Space, shared.

Copy-paste config[2 / 3]

Add it to your client.

Pick your client and paste. Set UM_TOKEN from a scoped key — the live, per-client blocks also live in your dashboard.
