ActiveCampaign MCP server: setup, pricing & agent-readiness

How to connect ActiveCampaign MCP to Claude Desktop

Add this block to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows), then restart Claude Desktop. Cursor and Codex use a similar schema.

{
  "mcpServers": {
    "activecampaign": {
      "command": "npx",
      "args": ["-y", "<server-package-name>"],
      "env": {
        "ACTIVECAMPAIGN_API_KEY": "your-api-key-here"
      }
    }
  }
}
// Server source: https://github.com/mmarqueti/activecampaign-mcp-server
// Check the server's README for the exact "command" and required env vars.

Some MCP servers require an API key. Check the source page for setup: github.com/mmarqueti/activecampaign-mcp-server.

Does ActiveCampaign MCP cost extra?

Community (free)

The ActiveCampaign MCP server is community-built — free to run, but you still pay for your ActiveCampaign subscription.

Community MCPs are normally self-hosted from a GitHub repo. There's no extra license fee.
Your ActiveCampaign account still needs whatever plan is required to access the data the MCP server queries.
Trade-off: zero MCP cost, but no guarantee it'll keep working when ActiveCampaign changes their UI or API.

What you can do with ActiveCampaign from an AI agent

Three shapes of agent workflow. Pick the row that matches how you actually use Claude / Cursor / Codex day to day.

INDIE / SOLO

Skip the dashboard, ask Claude

"What campaigns underperformed this week?" answered in seconds
Quick one-off questions without leaving the editor
Pipe ActiveCampaign data into your personal notes / docs without writing a script

Effort: 30 seconds — paste the config, restart Claude

AGENCY

Run client analysis at agent speed

Hand the MCP server to your team — every consultant can ask Claude about any client's ActiveCampaign account
Multi-account workflows without context-switching the ActiveCampaign UI
Reports you'd normally spend hours on, done before standup

Effort: An afternoon — set up auth per client

IN-HOUSE TEAM

Production agent workflows

Embed in your internal Codex / Cursor agents that triage ActiveCampaign data daily
Combine with other MCP servers in a multi-step agent chain
Constrain agents to read-only roles to keep production ActiveCampaign safe

Effort: Days — security review + role config

Limits and gotchas

Community MCP — not maintained by ActiveCampaign. Check the README and last-update date before depending on it.
Fallback: the REST API works for any flow the MCP server doesn't cover.
Auth flow: MCP servers usually inherit the underlying API auth method (both). Expect to configure that on first install.
Rate limits: MCP calls count against your underlying ActiveCampaign API quota. Burst usage from a curious agent can drain a daily allowance fast.

Agent-readiness verdict

Moderate agent fit with community MCP support. ActiveCampaign has a documented public API and native Claude integration, plus a community-maintained MCP server, but lacks official MCP backing, an OpenAPI spec, and structured output support. The missing OpenAPI spec and webhooks will require manual integration work for most agent workflows.

ActiveCampaign MCP & API FAQ

Is the ActiveCampaign MCP server official?+

No — it's a community build, not maintained by ActiveCampaign. Expect occasional drift and check the README before depending on it for production agents.

Can I use the ActiveCampaign MCP with Cursor or Codex?+

Yes — MCP is a protocol, not Claude-specific. Any MCP-capable client (Cursor, Codex, Windsurf, Zed) can use the same server config with minor path adjustments.

Does ActiveCampaign have a public API?+

Yes — public REST API at developers.activecampaign.com/reference/overview, auth via both.

Which LLMs does ActiveCampaign integrate with directly?+

ChatGPT, Claude. Direct integrations skip the need for custom API wrappers.
