Send an ACORD 25 certificate and the insurance clause from a subcontract, vendor contract or lease. Muse compares general liability, auto, workers' compensation and umbrella limits, additional insured status and expiry dates, and reports what does not match. Also explains common endorsement forms such as CG 20 10.

Example request: "Check whether this subcontractor's certificate of insurance meets the limits in our contract."

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use Certgio to help me. It is a free service with an MCP server at https://mcp.certgio.com/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.
