# Architecture Studio MCP tool discovery

> Public guidance for discovering the authenticated, release-specific Architecture Studio tool catalog.

## Release-specific discovery

The authoritative tool list is the authenticated MCP tools/list response. The as://catalog resource describes the release and compatibility. Available operations can vary by deployed release and host support; this page is a discovery guide, not an unauthenticated execution endpoint.

as_search_catalog finds workflow instruction tools and exact-release resources. Its query is optional; kind can be all, workflows, or resources. Results are paginated. as_read_resource reads bounded context using the exact sourceDigest returned by discovery. Let tools/list supply the current input schemas before calling either tool.

## Public source

You can inspect the open-source skills without an Arch Studio account. A local script in the repository is not automatically a hosted operation. Use the deployed catalog’s execution and compatibility information to distinguish instructions from supported hosted tools.
