The CData MCP Server for ActiveCampaign defines each connection to ActiveCampaign as a named configuration that Claude can use when sending natural language queries.

You create and manage these configurations using the MCP Configuration Tool. The tool automatically handles formatting, storage, and registration with Claude Desktop.

Understanding Connection Configurations

Each connection configuration is stored in a .mcp file. This file includes the details needed to initialize the connector when Claude starts a session.

• On Windows, configuration files are stored in "~/AppData/Roaming/CData/ActiveCampaign Data Provider/".
• On macOS, configuration files are stored in "~/Library/Application Support/CData/ActiveCampaign Data Provider/".

The .mcp file is a text file that contains a list of connection properties and a timestamp. For example:

#Tue May 20 15:48:40 EDT 2025
AuthScheme=Basic
User=myUser
Password=myPassword
Security Token=myToken

The configuration tool handles these settings automatically. Each saved configuration enables Claude to launch a dedicated MCP Server instance with the correct connector and options. Manual file editing is not required.

Connecting to ActiveCampaign

ActiveCampaign supports authenticating with the API Key. To connect to ActiveCampaign, in your account navigate to the Developer page and set the following:

• URL: Navigate to the My Settings page to set this property. For example: https://<yourAccountName>.api-us1.com
• APIKey: Navigate to the Settings page to set this property. Each user in your ActiveCampaign account has their own unique API key.

Make sure to distinguish between My Settings and Settings when setting these properties.
