About the customer.io MCP server

Connect customer.io once in Activepieces and every action it ships becomes a tool your assistant can call, behind the same server URL as the rest of your apps. Your agent reaches customer.io and 760+ other apps over a single connection, on our cloud or a self-hosted install.

Tools

customer.io tools your AI can run

Once connected, your assistant can call any of these customer.io actions by asking in plain language.

  • Create Event

    Create an event in Customer.io

    4 fields

  • Track Custom API Call

    CustomerIO Track Custom API Call (track.customer.io)

    10 fields

  • App Custom API Call

    CustomerIO App Custom API Call (api.customer.io)

    10 fields

Triggers

customer.io events your agent can watch

These start a run the moment something happens in customer.io, so work gets picked up on its own.

  • New Reporting Event

    Fires on a Customer.io reporting-webhook event (delivered, bounced, clicked, …). Subscribe to only the event types you need, and optionally match a single campaign, action, or recipient domain so unrelated events never start a run.

    4 fields

Give your assistant customer.io

Connect customer.io once and every tool above is callable from Claude, Cursor or any MCP client, behind the same server URL as 760+ other apps. Free to start.

customer.io MCP, answered.

No. That is the point of it. One Activepieces server exposes customer.io alongside every other piece you connect, so your client keeps a single connection.

Yes. Activepieces is open source and free to start, and the MCP server is included on every plan, from the free cloud tier to any self-hosted deployment.

Connect customer.io in Activepieces, enable the server under Settings → MCP Server, then paste your server URL into your client config. It authenticates over OAuth on first use.

It can call 3 tools, including Create Event, Track Custom API Call, App Custom API Call, and chain them with steps in other apps inside the same run.

Connections use OAuth2 with limited scopes and are stored under 256-bit encryption, with no API to read them back, so an agent gets scoped access rather than your keys.
