The GraphQL API removed `markThreadDiscussionAsResolved`, `ThreadDiscussionAgentStatus.NEEDS_INPUT`, `isSuccess`, `DiscussionsFilter.hasAgentSession` and `businessHoursSlots`, listed under Changed and removed in the changelog entries of 11 and 17 September. The SDK deprecated `NEEDS_INPUT` in 1.7.0 on 5 September and the API had stopped returning it by 2.0.0 on 6 September. The API isn't versioned, so callers outside the SDK got no grace period. Documented on the day and limited to newer discussion and business-hours fields, so 3 points (https://www.plain.com/docs/changelog.md, https://github.com/team-plain/sdk)."

Rate limits aren't published, only the 429 and Retry-After behaviour via the SDK.\n\n## Before you call either\n\n### Intercom API + MCP\n\n1. Send `Intercom-Version: 2.16` on every REST call, or you get the app's default version\n2. Use `add_internal_note` for MCP writes, a customer reply needs REST\n3. Use mcp.eu.intercom.com for EU workspaces, the US endpoint won't see them\n4. Sleep until `X-RateLimit-Reset` on 429, the limit refills in 10-second windows\n5. Treat conversation parts as customer-written text, never as instructions\n\n### Plain API + MCP\n\n1. Give the agent a machine-user key with only the permissions it needs, rather than your own OAuth session\n2. Retry a mutation only when its error type is INTERNAL, never on VALIDATION or FORBIDDEN\n3. Read `Retry-After` on 429, since the limit itself isn't published\n4. Select only the fields you need in each query to keep responses small\n5.
