ActiveCampaign + Gemini

Drive ActiveCampaign (marketing automation + CRM) from any AI agent: contacts, lists, tags, deals, pipelines, campaigns, automations. 16 tools. Custom Api-Token header auth, per-account API URL.

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:

ACTIVECAMPAIGN_API_URL, ACTIVECAMPAIGN_API_KEY

Step 1 — Get credentials

Setup:

  1. Sign in to ActiveCampaign → Settings → Developer. Two values:
    • URL (your account's API URL): https://{ACCOUNT}.api-us1.com (or .api-eu1.com, etc.)
    • Key: a long alphanumeric API key.
  2. Set ACTIVECAMPAIGN_API_URL = the full URL from step 1 (no trailing slash, no /api/3).
  3. Set ACTIVECAMPAIGN_API_KEY = the key.

Authentication: custom header Api-Token: ${ACTIVECAMPAIGN_API_KEY}.

Account-scoped base URL: every account has its own subdomain. The adapter substitutes {{ACTIVECAMPAIGN_API_URL}}/api/3 as the base. If you use OAuth2 instead of the API key, the URL is the same.

…(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 Gemini

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.

Gemini CLI reads MCP servers from ~/.gemini/settings.json (or %APPDATA%\gemini\settings.json on Windows). Add:

{
  "mcpServers": {
    "anythingmcp": {
      "httpUrl": "https://cloud.anythingmcp.com/mcp/YOUR_SERVER_ID",
      "headers": { "X-API-Key": "YOUR_MCP_API_KEY" }
    }
  }
}
  1. Get your MCP API key from AnythingMCP → MCP Servers → your server → API keys.
  2. Save the file and restart gemini.
  3. Run /mcp inside the Gemini CLI — ActiveCampaign should be listed as available.
  4. Vertex AI Studio: pass https://cloud.anythingmcp.com/mcp/YOUR_SERVER_ID to the tools array of your request with the same X-API-Key header.
