Install ActiveCampaign in Claude Code

What you need first

• Claude Code, installed.
• Docker, which gives the docker command the server starts with.
• Your own values for YOUR_MCP_TRANSPORT,YOUR_ACTIVECAMPAIGN_API_URL,YOUR_ACTIVECAMPAIGN_API_TOKEN.

Steps

1. Run this in a terminal, in the project folder. It adds the server for you in that project; put --scope user after claude mcp add to have it in every project.

claude mcp add --env MCP_TRANSPORT=YOUR_MCP_TRANSPORT --env ACTIVECAMPAIGN_API_URL=YOUR_ACTIVECAMPAIGN_API_URL --env ACTIVECAMPAIGN_API_TOKEN=YOUR_ACTIVECAMPAIGN_API_TOKEN --transport stdio activecampaign-mcp -- docker run -i --rm -e MCP_TRANSPORT -e ACTIVECAMPAIGN_API_URL -e ACTIVECAMPAIGN_API_TOKEN ghcr.io/ohneben/activecampaign-mcp:1.1.1

2. Replace YOUR_MCP_TRANSPORT,YOUR_ACTIVECAMPAIGN_API_URL,YOUR_ACTIVECAMPAIGN_API_TOKEN with your own values.
3. Start Claude Code and type /mcp: the server is listed with its state.

Check it worked

Ask Claude Code: List the tools of activecampaign-mcp.

If it does not start

Cannot connect to the Docker daemon

Docker is not running. Start it, then restart Claude Code.

The server starts, but its tools fail

A YOUR_… placeholder is still in the config, or its value is wrong.
