Connects to Movable Capital's dated, provider-verified rate data for high-yield savings, money market funds, CDs, Treasury bills and brokerage cash sweeps. Muse can look up the best current rates, check what a broker pays on uninvested cash, and estimate after-tax returns for a given balance and tax bracket.

Example request: "Where should I keep my $20,000 emergency fund, and how much more would I earn after taxes?"

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use Movable Capital to help me. It is a free service with an MCP server at https://www.movablecapital.com/api/mcp. It does not need an API key. 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.
