Sourcey helps startups discover and compare available credits from cloud providers, SaaS vendors, and grant programs. Search by need or vendor, compare offers side by side, and verify eligibility based on company facts. Includes service readiness reports for APIs and platforms.

Example request: "Find available AWS and Google Cloud credits we might qualify for as a new startup."

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