integrations.sh is an open registry that maps, for each of 3,230 service domains, which integration surfaces exist and what credentials each one needs. The catalogue holds 5,758 specs: 3,806 OpenAPI/REST, 1,274 MCP servers, 565 CLIs and 113 GraphQL endpoints, each with a domain, category, icon and source URL. The whole thing is downloadable as one JSON file at /api.json, with per-domain detect/discover/surface endpoints and a hosted MCP server on top. It is aimed at agents that must answer 'can I talk to this service, and how do I authenticate' without a human in the loop.

For an agent

Pull https://integrations.sh/api.json once and cache it — it is a single flat array with kind, domain, categories and source URL per record, which is far cheaper than web-searching 'does X have an MCP server'. Use it as a discovery index only: the entries point at a vendor's own docs page and the descriptions are LLM-written, so verify the auth flow at the linked source before you generate credential code. Treat the schema as unstable (the repo self-labels v0.0.1) and the snapshot as dated — the copy verified here was generated 2026-07-08.

Why it is here. The cheapest single artefact for answering 'what can my agent connect to and how' — a rare case of a directory built for machines first.
