# Quo (formerly OpenPhone) MCP server for AI agents.

actionlake is an MCP gateway: one remote MCP server that connects Claude and other MCP clients to Quo (formerly OpenPhone) and the rest of your systems. It gives your agent 43 Quo (formerly OpenPhone) actions (20 reads, 19 writes and 4 that wait for a confirmation) and holds the Quo (formerly OpenPhone) credential itself, so the agent never does. It paces Quo (formerly OpenPhone)'s limits and records every call.

Set up

## Connect Quo (formerly OpenPhone) 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 Quo (formerly OpenPhone).
   API key. 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` Quo API key: a workspace owner or admin opens Settings > API (quo.com workspace settings), chooses Generate API key,…
   ```
   account { op: "connections.requirements", service: "quo_openphone" }
   # 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: "quo_openphone.tasks.list" }
   # list tasks · read · 1 upstream call
   check { action: "quo_openphone.tasks.create", input: { … } }
   # free: inputs, permissions, cost and confirmations, nothing sent
   ```

## Prompts to paste into Claude.

Each one names the Quo (formerly OpenPhone) actions it will call, so you know what it reads and what it changes before you send it.

1. Read read
   Which Quo (formerly OpenPhone) tasks are overdue, and who owns each one?
   calls `quo_openphone.tasks.list`
2. Write write
   Create a task in Quo (formerly OpenPhone). Show me exactly what you will send before you save it.
   calls `quo_openphone.tasks.create`

Governance for Quo (formerly OpenPhone)

## Destructive actions wait for a yes.

4 Quo (formerly OpenPhone) actions are destructive. These are all of them:

- Delete a task by ID `quo_openphone.tasks.delete`
- Delete a contact `quo_openphone.contacts.delete`
- Delete a webhook by ID `quo_openphone.webhooks.delete`
- Send a text message `quo_openphone.messages.send`

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 quo_openphone.tasks.delete confirm_policy: **human**

Delete a task by ID?

**intent:** the user asked me to delete a task by ID

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

In the console, or from an emailed signed link.

**What do I need to connect Quo (formerly OpenPhone)?**

Quo API key: a workspace owner or admin opens Settings > API (quo.com workspace settings), chooses Generate API key,…. The free call account { op: "connections.requirements", service: "quo_openphone" } lists exactly what to paste.

**Can an AI agent delete or change things in Quo (formerly OpenPhone)?**

Only if its key allows it, and only with an explicit confirmation. 4 Quo (formerly OpenPhone) actions are destructive, including delete a task by ID, delete a contact and delete a webhook by ID. 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.

actionlake paces every call to the limits in the Quo (formerly OpenPhone) service file: 10 calls a second per connection. Repeated reads are answered from cache (18 Quo (formerly OpenPhone) actions can be), which never reaches Quo (formerly OpenPhone).

**What does a Quo (formerly OpenPhone) action cost?**

One upstream call, the only unit actionlake bills. A list that pages bills one call per page (43 Quo (formerly OpenPhone) actions page). Cache hits, searches, dry runs and calls Quo (formerly OpenPhone) refused with 401, 403, 429 or a 5xx are free. The Free plan includes 100,000 calls a month with no card.

**Which Quo (formerly OpenPhone) API does it cover?**

The Quo Public API v1 (1.0.0, OpenAPI 3.1.0) at api.quo.com. It is built from Quo (formerly OpenPhone)'s documentation as read on 22 October 2026. 43 actions in 17 areas, each one in the signed service file (version 1.0.0).

**Does actionlake keep my Quo (formerly OpenPhone) 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 Quo (formerly OpenPhone) 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.
