The MCP server at mcp.helpscout.net/mcp signs each person in through Help Scout's own OAuth page, is read-only for new connections, and follows that person's mailbox permissions. The Inbox API needs a separate app under My Apps, client credentials and a token that lasts 48 hours, and those credentials don't work for MCP. So the loop is split. Search and summarise through MCP, then POST /v2/conversations/{id}/notes for a draft and /reply when the customer should see it, through REST. Limits are published, 200, 400 or 800 calls a minute by plan, writes count as two and are capped at 12 per 5 seconds, and 429 carries X-RateLimit-Retry-After. The MCP article says plainly that pasted credentials reach the agent as-is. No OpenAPI, no published tool list, and the developer changelog URL returns 404. Three because each half is documented, and an agent working a queue has to hold two credentials and two mental models.

It groups the MCP tools under conversations, customers, inboxes, users, workflows, reports and Docs, and the names and schemas sit behind a sign-in. The article is plain that anything a customer pasted, credentials included, reaches the agent as-is, which tells an operator what the model will read. New MCP connections are read-only, so every write goes through the Inbox API. That reference describes each endpoint, documents fields and types per endpoint, and has an errors section with request and response examples, and an llms.txt serves it as Markdown. There's no OpenAPI file, and the developer changelog URL is a 404, though v2 carries a stated promise of backward compatibility. Three, because the REST reference is sound and the MCP tools are a headcount without definitions.
