v1.0.0 · draft-soden-wellknown-mcp-commerce-00

Future-proof your business for the AI era.

Generate a Beacon Spec Server Card in about five minutes. Free, no signup, runs entirely in your browser. Drop the file into /.well-known/mcp.json and AI assistants can discover and interact with your business.

A small file, a big shift

Your Server Card sits at /.well-known/mcp.json, a known path on your domain. Any MCP-compatible AI assistant can fetch it, learn what your business does, and call you on a customer’s behalf.

Like SEO, but for agents

SEO went mainstream because Yoast and schema.org generators removed the spec literacy from publishing. AI-driven discovery is the next layer of the open web. This builder is its on-ramp.

You already have most of this

Business name, description, hours, capabilities. If you have an OIDC sign-in already, you can paste the discovery URL and you’re most of the way there.
