  ## Agent discovery

  Agents can use the MPP services catalog before choosing which paid API to call:

  | Surface | URL | Use it for |
  | --- | --- | --- |
  | Web directory | [`https://mpp.dev/services`](https://mpp.dev/services) | Browse services, categories, providers, endpoints, and examples. |
  | Public catalog API | [`https://mpp.dev/api/services`](https://mpp.dev/api/services) | Fetch the JSON catalog directly from scripts, CLIs, or custom agents. |
  | Services MCP | [`https://mpp.dev/mcp/services`](https://mpp.dev/mcp/services) | Let an MCP-capable agent rank services, inspect payment offers, get usage recipes, and fetch advisory OpenAPI summaries. |

  The services MCP server is read-only. It does not register services, execute
  payments, sign transactions, or proxy paid API calls. Runtime `402` Challenges
  from the target service remain the authoritative source of current payment
  terms.

  For MCP client setup, Inspector smoke tests, agent prompts, and recommended
  tool-call recipes, see
