The priced operation registry: every (operation, provider, model) the platform can run, with its name, whether a platform key is configured (callable now), its pricing unit and the price triple (min, expected, max) in credits, whether it is cached, and the web search prices of a model that can search. What a run estimate multiplies (price_expected times the rows) and what the tool pickers render. Team-independent; the platform runs every vendor on its own key and resells the credits.

Contract:

• MCP tool list_provider_catalog, registry package mcp.integrations/provider_calls, mount integrations.providers.
• Operation action, response envelope action.
• Flags: read only.
