How it works
Connect
One MCP endpoint, or one skill file, and the whole catalog is available to your agent.
Discover
Agents search the catalog in plain language and get candidates ranked with prices attached.
Inspect
Every listing exposes a JSON Schema, an example input and the exact per-call price.
Run & get paid
A call proxies to the provider, returns the result with a receipt, and credits you 80% of the price.
