Znuny + ChatGPT

Znuny (the maintained OTRS fork, and the same API as OTOBO): search and read tickets with their articles, open tickets and add articles, over the GenericInterface REST web service on your own instance.

Prerequisites

See the full setup instructions baked into the connector (visible in the in-app store when you select the connector). The required environment variables for this connector are:

ZNUNY_URL, ZNUNY_WEBSERVICE, ZNUNY_USERNAME, ZNUNY_PASSWORD

Step 1 — Get credentials

A Znuny web service has to be created before any of this works. Znuny does not expose a REST API by default; you build one in the admin UI.

  1. Go to Admin → Web Services → Add web service and import Znuny's sample GenericTicketConnectorREST.yml (in the Znuny source it is development/webservices/GenericTicketConnectorREST.yml). That file defines exactly the four operations this adapter calls, and the routes below are its routes: GET /Ticket is TicketSearch, POST /Ticket is TicketCreate, GET /Ticket/:TicketID is TicketGet and PATCH /Ticket/:TicketID is TicketUpdate. If you wrote your own web service with different routes, change them here to match.

…(continued in the in-app connector instructions)

Step 2 — Install the adapter

curl -fsSL https://raw.githubusercontent.com/HelpCode-ai/anythingmcp/main/docker-compose.quickstart.yml -o docker-compose.yml
printf 'JWT_SECRET=%s\nENCRYPTION_KEY=%s\n' "$(openssl rand -hex 32)" "$(openssl rand -hex 32)" > .env
docker compose up -d

Step 3 — Add the connector in ChatGPT

Your server URL: in AnythingMCP, open MCP Servers → the server this connector is on, and copy its URL (https://cloud.anythingmcp.com/mcp/…). Use it wherever this guide shows YOUR_SERVER_ID.

ChatGPT adds MCP servers as plugins on its Plugins page, on the web and on paid plans. Developer mode is no longer needed. In a Business workspace only admins and owners can add one; in Enterprise and Edu an admin can grant the Create plugins with MCPs permission.

  1. Go to chatgpt.com/plugins, click Add, then Add custom MCP server.
  2. Enter a name, e.g. Name: Znuny.
  3. Under Connection, enter the Server URL https://cloud.anythingmcp.com/mcp/YOUR_SERVER_ID and keep Authentication on OAuth.
  4. Select I understand and want to continue, then Create as a plugin. When ChatGPT asks, sign in to AnythingMCP and allow access.
  5. Install the new plugin from your personal plugins, then type @ in a chat and pick it.

FAQ

Does the free ChatGPT plan work with custom MCP servers? OpenAI documents custom MCP servers for paid plans only; the Free plan is not on its list.
