Finds the money hiding in your life. A read-only MCP connector for AI assistants such as Meta Muse: open class action settlements, CPSC product recalls with refunds, unused credit card credits, expiring loyalty points and birthday freebies, each with an official link.

Built for the Muse Connector Platform. Works with any MCP client, and every tool doubles as a REST endpoint.

Tools

Tool	What it answers	REST
search_settlements	Which open U.S. class action settlements match the brands I use? Deadline, payout, proof needed, claim link.	GET /api/v1/settlements
match_recalls	Has anything I own been recalled in the last three years, and what is the remedy?	GET /api/v1/recalls
card_benefits	Which statement credits and perks on my cards reset soon and how do I use them?	GET /api/v1/cards
points_expiry	When do my miles and points expire, and what keeps them alive?	GET /api/v1/points
birthday_freebies	What do chains near me give away on birthdays, and by when must I join?	GET /api/v1/freebies
check_for_new	What is new since my last check? One call for a weekly sweep.	GET /api/v1/updates

Plus one MCP prompt, find_my_money, that walks an assistant through a full sweep.

How it works

data/settlements.json  ← scripts/build-data.ts  ← OpenClassActions.com + ClassAction.org (daily, GitHub Action)
data/recalls.json      ← scripts/build-data.ts  ← CPSC recalls API, 3-year window (daily) + live top-up per request
data/cards.json, programs.json, freebies.json     hand-maintained catalogues with last_reviewed + confidence per entry

src/app.ts     Express: POST /mcp (stateless streamable HTTP, official SDK), /api/v1/*, pages, /openapi.json
src/mcp.ts     registers the six tools (all readOnlyHint) and the prompt
src/tools/*    pure functions; the MCP and REST layers are thin wrappers
api/index.js   Vercel entry (imports dist/app.js)

No database, no accounts, no stored personal data. Matching is a small TF-IDF index over titles, product names and summaries, so "Bank of America" scores higher than "America" and generic words do not match everything.
