Seamlessly use MPP-enabled services with your agent.
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 | Browse services, categories, providers, endpoints, and examples. |
| Public catalog API | https://mpp.dev/api/services | Fetch the JSON catalog directly from scripts, CLIs, or custom agents. |
| Services MCP | 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 Discover MPP services on Tempo docs.
