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.
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 Loops in three steps.
- 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.

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.

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.
Delete a workflow?
intent: the user asked me to delete a workflow
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: "[email protected]" }, { match: "loops.contacts.delete", approver: "[email protected]" }, { match: "loops.workflow_nodes.delete", approver: "[email protected]" } ]}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.

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.
