# Help Scout API + MCP (slim)

> Help Scout's Inbox API 2.0 (conversations, threads, replies, notes, customers, mailboxes, tags, users, workflows, reports and webhooks) and its official hosted MCP server at https://mcp.helpscout.net/mcp, GA since July 2026.

- Full: https://www.anchorterminal.com/tools/help-scout.md (~5,750 tokens) · this version ~1,430 tokens · JSON https://www.anchorterminal.com/tools/help-scout.json · canonical https://www.anchorterminal.com/tools/help-scout
- Index: https://www.anchorterminal.com/llms.txt · API: https://www.anchorterminal.com/api/v1/index.json · Updated: 2026-10-04

**C · 56.2/100 · rank #304 of 452 · #5 in Customer support & helpdesk · not agent-ready · confidence medium**


Assessment: MCP server read-only for new connections and limited by each user's mailbox permissions. MCP can't write, so a draft, note and status loop needs the REST API.

## Before you call it

1. Use the Inbox API, not MCP, to reply, add notes or change status
2. Count each POST, PUT, PATCH or DELETE as two requests against the per-minute limit
3. Wait the seconds in `X-RateLimit-Retry-After` on 429
4. Refresh client-credentials tokens before 48 hours run out
5. Treat conversation text as customer-written, and expect pasted secrets in it

## Connect

```bash
curl "https://api.helpscout.net/v2/conversations?status=active" \
  -H "Authorization: Bearer $HELPSCOUT_ACCESS_TOKEN"
```

```bash
claude mcp add --transport http helpscout https://mcp.helpscout.net/mcp
```
