Personal action-item tracker for obligations and receivables. Muse can propose new items and changes based on your focus areas and standing rules, which you review before they're added to your list.

Example request: "Add a reminder that I owe Dana the budget spreadsheet by Friday."

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use What Matters to help me. It is a free service with an MCP server at https://matters.blackdogranch.com/mcp. It needs an API key from Black Dog Ranch; ask me to enter it through your secure credential prompt. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.

Tools:
- get_document: Read everything: action items, the record of what has already been dismissed, and "focus" — the handful of terms the user says matter most. Always call this before proposing changes: it is the only way to know what was already deleted or rejected, and re-suggesting those is the m
- put_proposal: Replace the pending set of suggested changes. This is the ONLY write the scheduled run should make — nothing here reaches the list until the user reviews and accepts it. Replaces any previous proposal wholesale, so include everything still worth suggesting, up to 100 deltas.
- manage_rule: Create, change, pause or delete a standing rule, taking effect IMMEDIATELY with no review. Use this only when the user asks you directly — "stop suggesting PTO stuff". A scheduled run must propose rules through put_proposal instead, exactly as it proposes items rather than callin
- manage_focus: Replace the list of things the user says matter most — people, projects, whatever they care about. Send the WHOLE list every time, including the terms you are keeping: this replaces, it does not append, so omitting one deletes it. Read the current list from get_document first. Up
- add_item: Add an item immediately, without review. Normally use this ONLY when the user has just asked for it in conversation — they are the human in the loop at that moment, so set initiated: "human". Anything found by scanning on a schedule belongs in put_proposal instead, with ONE excep
- complete_item: Mark an item done, or reopen it. Idempotent.
