Lemlist + ChatGPT
Drive Lemlist (cold email + multichannel outreach) from any AI agent: campaigns, leads (in-campaign prospects), team members, hooks. 11 tools, API-key Basic 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:
LEMLIST_API_KEY
Step 1 — Get credentials
lemlist.com).
Setup:
- Sign in to Lemlist → top-right avatar → Settings → Integrations → API → Get my API key.
- Copy the key. Set
LEMLIST_API_KEY.
Authentication: HTTP Basic Auth — Authorization: Basic base64('':${LEMLIST_API_KEY}) — username is empty, password is the API key. (Yes, swapped from the usual: empty username, key as password.) The adapter handles this via BASIC_AUTH with username='' and password=key.
Campaign model: Lemlist's central unit. A campaign has a sequence of steps (email + waits + LinkedIn touches). You add leads (prospects) to a campaign — the campaign then drips touchpoints to each lead.
…(continued in the in-app connector instructions)
Step 2 — Install the adapter
curl -fsSL https://raw.githubusercontent.com/HelpCode-ai/anythingmcp/main/docker-compose.quickstart.yml -o docker-compose.yml
printf 'JWT_SECRET=%s\nENCRYPTION_KEY=%s\n' "$(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 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:
Lemlist. - 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.

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