Help Scout MCP Server

An MCP server that gives AI assistants direct access to your Help Scout inboxes, conversations, customers, organizations, threads, and Docs knowledge base. Search tickets, pull customer and account context, inspect articles, spot patterns, and get answers without leaving your editor or chat window.

Built by a Help Scout customer who wanted to give his support team superpowers. If you handle customer conversations in Help Scout and want AI to help you work faster, this is for you.

What You Can Do

• Search conversations by keyword, date range, status, tag, email domain, or ticket number
• Look up customers by name, advanced query syntax, or exact email address
• Explore organizations with direct customer and conversation traversal
• Inspect conversation detail with raw ticket metadata, summaries, full threads, attachments, and original source
• Pull full thread history into context before drafting a reply
• Get conversation summaries with the original customer message and latest staff response
• Search and retrieve Docs articles from the separate Help Scout Docs API
• Pull Help Scout reports and metadata for company, conversations, Docs, channels, productivity, happiness, users, teams, system users, statuses, routing, and webhooks
• Monitor inbox activity across multiple inboxes with a single query
• Take action with opt-in writes: draft replies, internal notes, tags, status, assignment, snooze, and more, all off by default
• Reduce message payloads with optional message content redaction and scoped inbox access

Quick Start

Claude Desktop & Claude Cowork (Recommended)

One-click install using Desktop Extensions. One install covers both Chat and Cowork sessions in the Claude desktop app.

1. Download the latest .mcpb file from releases
2. Double-click to install (or drag into Claude Desktop)
3. Enter your Help Scout App ID and App Secret in the extension settings; the settings also carry toggles for message redaction and the opt-in write surface
4. Restart Claude Desktop

If the tools don't show up in a Cowork session, update the desktop app to the latest version and start a fresh session. (Cowork walkthrough)

Optional: add the helpscout-navigator skill so Claude picks the right operation faster. Go to Customize, click + > Add marketplace from GitHub, enter drewburchfield/help-scout-mcp-server, and install helpscout-navigator.

Claude Code

Register the server, then optionally add the helpscout-navigator skill, which teaches Claude to pick the right operation for each query.

claude mcp add helpscout \
  --env HELPSCOUT_APP_ID=your-app-id \
  --env HELPSCOUT_APP_SECRET=your-app-secret \
  -- npx -y help-scout-mcp-server

Then, for the navigation skill:

1. Run /plugin marketplace add drewburchfield/help-scout-mcp-server
2. Run /plugin install helpscout-navigator

The server alone gives you the tools; the skill also teaches the AI how to use them well.

For Cursor, VS Code, and Other MCP Clients

Add to your MCP client's config file (e.g., claude_desktop_config.json, .cursor/mcp.json):

{
  "mcpServers": {
    "helpscout": {
      "command": "npx",
      "args": ["help-scout-mcp-server@2.1.0"],
      "env": {
        "HELPSCOUT_APP_ID": "your-app-id",
        "HELPSCOUT_APP_SECRET": "your-app-secret",
        "HELPSCOUT_DOCS_API_KEY": "optional-docs-api-key"
      }
    }
  }
}

Docker

docker run -e HELPSCOUT_APP_ID="your-app-id" \
  -e HELPSCOUT_APP_SECRET="your-app-secret" \
  -e HELPSCOUT_DOCS_API_KEY="optional-docs-api-key" \
  drewburchfield/help-scout-mcp-server:2.1.0

Getting Your API Credentials

1. Go to Help Scout > My Apps > Create Private App
2. Copy your App ID and App Secret

Help Scout uses OAuth2 Client Credentials flow exclusively. Personal Access Tokens are not supported. The app authenticates as the user who created it, with that user's permissions; there is no separate scope selection, which is why the server's own write gating defaults to off.

Alternative names HELPSCOUT_CLIENT_ID / HELPSCOUT_CLIENT_SECRET are also supported.

Docs knowledge base tools use Help Scout Docs API v1, which is separate from the Mailbox API. Set HELPSCOUT_DOCS_API_KEY only if you want to use listDocs*, searchDocsArticles, getDocsArticle, or redirect tools.

Tools

The server advertises three tools that together reach every supported read operation (55 across the Mailbox and Docs APIs):

This keeps the advertised surface small enough that AI clients don't drown in schemas, while every read capability stays one search away. Operations in the current registry also remain callable by name directly. Tool names removed in the v2.0.0 consolidation (for example comprehensiveConversationSearch, structuredConversationFilter, and searchInboxes) are not; their capabilities live in searchConversations and listAllInboxes.

An optional fourth tool, write_help_scout, appears only when an operator turns writes on. See Write operations (opt-in).

For the MCP compatibility contract and roadmap, see:

• MCP tool contract
• MCP vs CLI boundary
• MCP tool surface roadmap

Which operation should I use?

Run any of these via read_help_scout:

Inboxes are auto-discovered when the server connects. AI agents get inbox IDs in their instructions automatically, so no lookup step is needed.

Write operations (opt-in)

A default install is read-only. It advertises the three tools above and nothing else, unchanged from 2.0. Writes exist only after an operator sets a flag.

Tier 1 covers draft replies, internal notes, status changes, assign and unassign, adding and removing tags, custom field values, snooze and unsnooze, and moving a conversation to another inbox. None of it emails anyone: a draft is saved unsent, and a note is visible to teammates only.

Tier 2 is the only path that reaches a customer, and it needs both flags. Every call to sendReply or publishDraft must also carry confirmation naming the operation and the target:
