ActiveCampaign

ActiveCampaign runs locally from a container image in an OCI registry such as Docker Hub or GitHub Container Registry: ghcr.io/ohneben/activecampaign-mcp:1.1.1. It speaks MCP over stdio, so the client starts it as a program and talks to it through standard input and output. It needs Docker or another OCI container runtime; started with docker run — the usual command is docker run -i --rm -e MCP_TRANSPORT -e ACTIVECAMPAIGN_API_URL -e ACTIVECAMPAIGN_API_TOKEN -e MCP_AUTH_TOKEN ghcr.io/ohneben/activecampaign-mcp:1.1.1. It reads these environment variables: MCP_TRANSPORT (required), ACTIVECAMPAIGN_API_URL (required), ACTIVECAMPAIGN_API_TOKEN (required, secret) and MCP_AUTH_TOKEN (secret); set them in the client's configuration for this server.

In the mcpServers JSON format that many desktop and editor MCP clients read, the entry looks like this (placeholders in angle brackets):

{
  "mcpServers": {
    "activecampaign-mcp": {
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
        "-e",
        "MCP_TRANSPORT",
        "-e",
        "ACTIVECAMPAIGN_API_URL",
        "-e",
        "ACTIVECAMPAIGN_API_TOKEN",
        "-e",
        "MCP_AUTH_TOKEN",
        "ghcr.io/ohneben/activecampaign-mcp:1.1.1"
      ],
      "env": {
        "MCP_TRANSPORT": "<value>",
        "ACTIVECAMPAIGN_API_URL": "<value>",
        "ACTIVECAMPAIGN_API_TOKEN": "<secret>",
        "MCP_AUTH_TOKEN": "<secret>"
      }
    }
  }
}
