Omnisend + ChatGPT
Manage Omnisend (e-commerce marketing automation: contacts, campaigns, events, products, categories) from any AI agent. 9 tools, X-API-KEY auth.
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:
OMNISEND_API_KEY
Step 1 — Get credentials
This connector wraps the Omnisend REST API v3 (api.omnisend.com/v3).
Setup:
- Log into https://app.omnisend.com → top-right avatar → Store settings → Integrations & API → API keys → Create API key.
- Set
OMNISEND_API_KEY.
Authentication: X-API-KEY: ${OMNISEND_API_KEY}.
Contact statuses: subscribed, unsubscribed, nonSubscribed — per channel (email vs SMS).
Custom events: trigger automations via the events endpoint. Send an event with name + email/contactID + properties; Omnisend matches it to active workflows.
Pagination: cursor-based via paging.next. limit (max 250).
Rate limits: 400 req/min per token. 429 with Retry-After.

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 showsYOUR_SERVER_ID.
ChatGPT connects to MCP servers as custom apps in developer mode, available on paid plans (not on Free). On Business and Enterprise workspaces an admin may have to allow it first.
- In ChatGPT, open Settings → Security and login and turn on Developer mode.
- Go to chatgpt.com/plugins and click +.
- Enter a name and a short description, e.g. Name:
Omnisend. - Under Connection, enter the MCP server URL
https://cloud.anythingmcp.com/mcp/YOUR_SERVER_IDand create the connection. - When ChatGPT asks, sign in to AnythingMCP (OAuth) and allow access.

Does the free ChatGPT plan work with custom MCP connectors? No. Custom MCP connections need developer mode, which is only on paid plans.
