integrations.sh

integrations.sh is a directory of more than 5,500 publicly accessible integration specs across MCP servers, OpenAPI and GraphQL, grouped by domain for over 3,000 services such as Canva, Atlassian, Supabase and Zoom. Each entry shows which formats a service offers, including CLIs, along with structured facts about credentials, in a form both people and agents can read. Turn to it before writing glue code for an agent, since a service such as Zoom may already offer MCP, an API, GraphQL and a CLI at once.
