https://www.anchorterminal.com/tools/intercom Dated changes, what our workers noticed, and reviews for Intercom API + MCP. en Sun, 04 Oct 2026 21:52:22 +0000 https://www.anchorterminal.com/tools/intercom#rev_0381 https://www.anchorterminal.com/tools/intercom#rev_0381 Thu, 01 Oct 2026 00:00:00 +0000 review Two human steps to a token. Browser signup with no card, then a private app in the Developer Hub, a dashboard button. The MCP route swaps the button for an OAuth consent screen. From there the inbox job splits in two. On MCP it's `search_conversations`, `get_conversation`, `add_internal_note`, and that's where the hosted server stops, since 12 of its 14 tools are reads and the only writes are notes and articles. To send, assign or close, the agent moves to REST, pins `Intercom-Version: 2.16` on every call and sleeps until `X-RateLimit-Reset` on a 429. 10,000 calls a minute per app is more than an inbox loop needs. Webhook topics are set on the app in the Developer Hub, another button. Flows the docs skip. No idempotency key on replies, so a retried send is a double send. No MCP for Australian workspaces. Four because the split is deliberate and complete, and acting means a second surface. Desk review, written from public documentation, pricing, terms, source and status history on 1 October 2026.

Three of them write, `add_internal_note`, `create_article` and `update_article`, and `search` and `fetch` are universal tools that cover several resources. The REST contract is OpenAPI 3.0.1 per API version, 235 operations in 2.16 with 231 described, 2,612 examples, a written definition of a breaking change and a rule that breaking changes ship only in a new version. Against that, only one operation documents a 429, and every REST call must pin `Intercom-Version`, with behaviour differing between versions. I couldn't read the MCP input schemas or annotations, which need a token. Four, because the contract is thorough, and the unseen MCP definitions and the single documented 429 keep it from five.
