Hightouch MCP server for AI agents.

actionlake is an MCP gateway: one remote MCP server that connects Claude and other MCP clients to Hightouch and the rest of your systems. It gives your agent 61 Hightouch actions (28 reads, 30 writes and 3 that wait for a confirmation) and holds the Hightouch credential itself, so the agent never does. It paces Hightouch's limits and records every call.

100,000 free calls a month. No card, no email, no password: press Start a free sandbox on the next screen and keep the key it shows you.

Set up

Connect Hightouch in three steps.

  1. 01

    Add actionlake to Claude.

    Run the command once in Claude Code; its consent page can create a free sandbox: 100,000 calls a month, no card. In the Claude app, add a custom connector with the URL below and paste your key on the consent page. Creating a new sandbox from the Claude app is not yet tested by us.

    https://connect.actionlake.com/mcp
  2. 02

    Connect Hightouch.

    Bearer token. No consent screen: your agent can connect it for you, but the key then passes through your chat. To keep it out of the model's context, paste it in the console instead. actionlake stores what you paste write-only, sealed under your tenant's key.

    • access_tokenHightouch API key
    account { op: "connections.requirements", service: "hightouch" }
    # free: exactly what to paste, and what is found for you
  3. 03

    Make the first call. Check before a write.

    Ask in plain words; Claude picks the action. Before anything changes, check validates the call and prices it, for free.

Try it

Prompts to paste into Claude.

Each one names the Hightouch actions it will call, so you know what it reads and what it changes before you send it.

  1. Readread

    List Models in Hightouch and tell me what stands out.

    callshightouch.models.list

  2. Writewrite

    Create Sync in Hightouch. Show me exactly what you will send before you save it.

    callshightouch.syncs.create

Governance for Hightouch

Destructive actions wait for a yes.

3 Hightouch actions are destructive. These are all of them:

  • Delete Synchightouch.syncs.delete
  • Delete Modelhightouch.models.delete
  • Delete Decision Engine Messagehightouch.decision_messages.delete

A destructive action runs only with confirm: true. Under the human policy the agent cannot confirm for itself: the run stops until a named person approves, in the console or from a signed link in an email. The cap on a key is refused before the call is sent, never after.

dohightouch.syncs.deleteconfirm_policy: human

Delete Sync?

Illustrative. Scoped to Hightouch only, capped at 2,000 upstream calls, every write confirmed, and the destructive ones approved by a named person.

Cost

What Hightouch costs on actionlake.

Every Hightouch action is one upstream call, the only thing actionlake bills. Searching, check, cost, account and any call Hightouch refused with 401, 403, 429 or a 5xx are free. Paid plans start at US$49 a month for 250,000 calls, with overage from US$0.30 down to US$0.18 per 1,000.

Questions

The Hightouch MCP server, answered.

Is there a Hightouch MCP server for Claude?

Yes. actionlake is an MCP gateway: a remote MCP server that gives Claude, or another MCP client, 61 Hightouch actions across syncs, decision messages, models and sync drafts, through the same eight tools it uses for every other connector. actionlake is independent; it is not made or endorsed by Hightouch.

What do I need to connect Hightouch?

Hightouch API key. The free call account { op: "connections.requirements", service: "hightouch" } lists exactly what to paste.

Can an AI agent delete or change things in Hightouch?

Only if its key allows it, and only with an explicit confirmation. 3 Hightouch actions are destructive, including delete Sync, delete Model and delete Decision Engine Message. Each runs only with confirm: true. Under the human confirm policy, or an approval rule on the key, the run waits until a named person approves it.

Will an AI agent use up my Hightouch API limit?

actionlake paces every call to the limits in the Hightouch service file: 200 calls per 10 seconds per connection. Repeated reads are answered from cache (28 Hightouch actions can be), which never reaches Hightouch.

What does a Hightouch action cost?

One upstream call, the only unit actionlake bills. A list that pages bills one call per page (61 Hightouch actions page). Cache hits, searches, dry runs and calls Hightouch refused with 401, 403, 429 or a 5xx are free. The Free plan includes 100,000 calls a month with no card. Paid plans start at US$49 a month for 250,000 calls, with overage from US$0.30 down to US$0.18 per 1,000.

Which Hightouch API does it cover?

The Hightouch REST API v1 (OpenAPI 3.0.0) at api.hightouch.com/api/v1. It is built from Hightouch's documentation as read on 23 October 2026. 61 actions in 21 areas, each one in the signed service file (version 1.0.0).

Does actionlake keep my Hightouch data, and where?

actionlake processes and stores data in Sydney, Australia; there is no US region yet. Reads may be cached for up to 5 minutes, and a write clears the reads it affects. Each run's request and response is kept, sealed, for your plan's trace window: 1 day on Free, 3 days on Starter, 7 days on Pro, 14 days on Team, 30 days on Business and 30 days on Enterprise. Your Hightouch credential is sealed under your tenant's key, never logged and never returned. Your traffic is not used to train models.

Which AI clients can use it?

Claude Code, tested by us end to end, and the Claude app as a custom connector, tested by us with an existing key. Other MCP clients that support remote servers over Streamable HTTP (MCP revisions 2025-06-18 and 2025-11-25) and OAuth dynamic client registration, or a bearer header, should connect the same way; we have not tested them. Or plain REST, under the same action names.
