# Loops MCP server for AI agents.

actionlake is an MCP gateway: one remote MCP server that connects Claude and other MCP clients to Loops and the rest of your systems. It gives your agent 75 Loops actions (34 reads, 36 writes and 5 that wait for a confirmation) and holds the Loops credential itself, so the agent never does. It paces Loops's limits and records every call.

[Connect Loops free](https://actionlake.com/console?start=sandbox) [See pricing](https://actionlake.com/pricing)

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.

`claude mcp add --transport http actionlake https://connect.actionlake.com/mcp`

the first call

```
do {
  action: "loops.audience_segments.list",
  intent: "check which Loops account is connected"
}
# List audience segments · read · 1 upstream call
```

- 75 actions in one signed file
- 34 read look, never change
- 36 write create and update
- 5 wait for a yes destructive, confirmed first

Set up

## Connect Loops 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 Loops.
   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.
   - `api_key` Loops API key, from Settings > API in app.loops.so
   ```
   account { op: "connections.requirements", service: "loops" }
   # 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.
   ```
   do    { action: "loops.audience_segments.list" }
   # list audience segments · read · 1 upstream call
   check { action: "loops.audience_segments.create", input: { … } }
   # free: inputs, permissions, cost and confirmations, nothing sent
   ```

Top actions

## The Loops API, shaped for agents.

The ids your agent types, what each does, and the one name it shares with other systems. 29 of Loops's 29 action names are shared with at least one other connector, so an agent learns them once.

| Action | What it does | Effect | Same name in |
| --- | --- | --- | --- |
| `loops.audience_segments.list` List audience segments | List audience segments. | read | `comm.audience_segment.list` 22 connectors |

Try it

## Prompts to paste into Claude.

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

1. Read read
   List audience segments in Loops and tell me what stands out.
   calls `loops.audience_segments.list`
2. Write write
   Create an audience segment in Loops. Show me exactly what you will send before you save it.
   calls `loops.audience_segments.create`

Governance for Loops

## Destructive actions wait for a yes.

5 Loops actions are destructive. These are all of them:

- Delete a workflow `loops.workflows.delete`
- Delete a contact `loops.contacts.delete`
- Delete a workflow node `loops.workflow_nodes.delete`
- Remove a contact from suppression list `loops.contact_suppressions.delete`
- Delete workflow nodes recursively `loops.workflow_nodes.delete_recursive`

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.

do loops.workflows.delete confirm_policy: **human**

Delete a workflow?

**intent:** the user asked me to delete a workflow

run suspended · waiting for a named person · key _loops-agent_ cannot confirm itself

In the console, or from an emailed signed link.

a key for this connector

```
account {
  op: "keys.create", name: "loops-agent",
  allowed_actions: ["loops.*"], cap_calls: 2000,
  confirm_policy: "human_for_writes",
  approval_rules: [
    { match: "loops.workflows.delete", approver: "lead@example.com" },
    { match: "loops.contacts.delete", approver: "lead@example.com" },
    { match: "loops.workflow_nodes.delete", approver: "lead@example.com" }
  ]
}
```

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

Cost

## What Loops costs on actionlake.

Every Loops action is one upstream call, the only thing actionlake bills. Searching, `check`, `cost`, `account` and any call Loops 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.

- 1 upstream call per action all 75 Loops actions
- 11 actions page each page of a long list is one call
- 34 reads can be cached a cache hit costs nothing
- 100,000 calls a month, free paid plans from US$49 a month for 250,000

Questions

## The Loops MCP server, answered.

**Is there a Loops MCP server for Claude?**

Yes. actionlake is an MCP gateway: a remote MCP server that gives Claude, or another MCP client, 75 Loops actions across workflow nodes, transactional emails, contacts and workflows, through the same eight tools it uses for every other connector. actionlake is independent; it is not made or endorsed by Loops.

**What do I need to connect Loops?**

Loops API key, from Settings > API in app.loops.so. The free call account { op: "connections.requirements", service: "loops" } lists exactly what to paste.

**Can an AI agent delete or change things in Loops?**

Only if its key allows it, and only with an explicit confirmation. 5 Loops actions are destructive, including delete a workflow, delete a contact and delete a workflow node. 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 Loops API limit?**

actionlake paces every call to the limits in the Loops service file: 10 calls a second per connection. Repeated reads are answered from cache (34 Loops actions can be), which never reaches Loops.

**What does a Loops action cost?**

One upstream call, the only unit actionlake bills. A list that pages bills one call per page (11 Loops actions page). Cache hits, searches, dry runs and calls Loops 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 Loops API does it cover?**

The Loops API v1 (OpenAPI 1.22.6) at app.loops.so. It is built from Loops's documentation as read on 23 October 2026. 75 actions in 21 areas, each one in the signed service file (version 1.0.0).

**Does actionlake keep my Loops 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 Loops 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.
