Groove MCP Server (read-only, AP research)

A Model Context Protocol (MCP) server for researching accounts-payable chatter in Groove HQ — look up a vendor's conversations, drill into messages, and get per-channel context.

How it works — data sources (important)

This fork does not read conversations over GraphQL. Live introspection with a real admin token proved the v2 GraphQL conversation surface is not accessible to our token: there are no conversations / conversation / messages root query fields, and the Conversation / Message / ConversationFilter types do not exist for this credential. Groove REST v1 (GET /v1/tickets) does return real data, so it is the only reachable path to conversation data.

The GraphQL conversation/message queries that shipped upstream were dead code and have been removed (the GraphQL client is retained only for the contacts path). See docs/audit/assumption-inventory.md for the full trail.

Authentication uses an Authorization: Bearer <token> header — the token is never placed in a URL/query string.

Installation

Get your GROOVE_API_TOKEN from https://YOUR_SUBDOMAIN.groovehq.com/settings/developer/api.

Then add the server (local build):

npm install && npm run build
claude mcp add groove-mcp node ~/path/to/groovehq-mcp/dist/index.js -s user \
  --env GROOVE_API_TOKEN=your_groove_api_token_here

GROOVE_API_URL (GraphQL endpoint, used only for the contacts path) defaults to https://api.groovehq.com/v2/graphql. The REST v1 base is https://api.groovehq.com/v1.

Available Tools

Conversations (REST v1)

• listConversations — vendor/account conversation lookup, filtered server-side and paged to completion. Returns:

  {
    "pagination": {
      "total_count": 102,   // Groove's true total for this query
      "returned": 102,      // how many are in this response
      "complete": true,     // returned === total_count (nothing hidden)
      "truncated": false,   // true only if capped by maxResults
      "pages_fetched": 3,
      "per_page": 50,
      "note": "Complete: all 102 matching conversation(s) returned."
    },
    "filtersApplied": { "customer": "artubing@tejastubular.com" },
    "conversations": [ /* … */ ]
  }

  Always check pagination.complete / total_count. If complete is false, the result is a partial set and must not be treated as exhaustive.

  Parameters (each pushed to Groove v1 — no client-side filtering):

  • customer — vendor email or Groove contact id (Groove v1 customer). The correct way to get all of a vendor's conversations.

  • contactId — back-compat alias for customer.

  • state — unread | opened | closed | snoozed (v1 state).

  • assignee — assignee email/id (v1 assignee).

  • folder — folder id (v1 folder).

  • maxResults — explicit cap on total results. Omit to return every match.

  • channelId, tagIds — not supported by Groove v1 /tickets; if supplied they are not applied and are reported under unsupportedFilters (never silently approximated).

• getConversation — one conversation by bare ticket id (id, required).

• listMessages — messages for a conversation by bare ticket id (conversationId, required; optional limit).

Write operations (createConversation, updateConversation, closeConversation, sendMessage, createNote, createContact, updateContact) are still registered from upstream but are out of scope for this read-only server and should be stripped in a follow-up; several are non-functional against this token.

Contacts (GraphQL v2)

• listContacts — search, limit, after.

• getContact — id (required).

Agents / Knowledge Base (GraphQL v2, scope-dependent)

• listAgents, getAgent, getAvailableAgents, searchKbArticles — may return authorization errors on AP-scoped tokens (surface not guaranteed).

Known constraint — invoice-number search is not yet built

The core AP use case is finding a conversation by invoice number. Groove v1 /tickets has no keyword/full-text search parameter. Invoice numbers live in ticket titles (e.g. "Invoice 336205 from Tejas Tubular"), so search must be done differently. See docs/audit/search-constraint.md for the options (scope-by-customer-then-match-titles vs. a dedicated Groove search endpoint) — by design this is documented, not implemented, pending a design decision.
