3CX MCP server for AI agents.

actionlake is an MCP gateway: one remote MCP server that connects Claude and other MCP clients to 3CX and the rest of your systems. It gives your agent 576 3CX actions (294 reads, 192 writes and 90 that wait for a confirmation) and holds the 3CX credential itself, so the agent never does. It paces 3CX'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 3CX 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 3CX.

    OAuth 2.0, client credentials. Paste the app's client id and secret; actionlake fetches and renews the token, and nobody has to sign in. actionlake stores what you paste write-only, sealed under your tenant's key.

    • client_idClient ID of the 3CX API service principal (Admin Console > Integrations > API; the DN you gave it)
    • client_secretAPI key shown once when the service principal was created
    • hostWhere your 3CX lives: your host
    account { op: "connections.requirements", service: "three_cx" }
# 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: "three_cx.users.list" }# list users · read · 1 upstream callcheck { action: "three_cx.users.create", input: { … } }# free: inputs, permissions, cost and confirmations, nothing sent

Top actions

The 3CX API, shaped for agents.

The ids your agent types, what each does, and the one name it shares with other systems. 17 of 3CX's 17 action names are shared with at least one other connector, so an agent learns them once.

Try it

Prompts to paste into Claude.

Each one names the 3CX actions it will call, so you know what it reads and what it changes before you send it.

  1. Readread

    Find the 3CX contacts with no email address, so we can clean them up.

    callsthree_cx.contacts.list

  2. Writewrite

    Create a Users record in 3CX. Show me exactly what you will send before you save it.

    callsthree_cx.users.create

  3. Across systemsread

    Which contacts are in both 3CX and NetSuite, and how many are in only one of them?

    callsthree_cx.contacts.listnetsuite.views.contacts

Across your systems

3CX, joined to the rest of your business.

One ask fetches from 3CX and another system, joins the rows on the same customer on our side, and hands your agent the answer, not every row.

  • Which contacts are in both 3CX and NetSuite, and how many are in only one of them?

    three_cx.contacts.list + netsuite.views.contacts, on crm.contact · NetSuite

  • Which contacts are in both 3CX and HubSpot CRM, and how many are in only one of them?

    three_cx.contacts.list + hubspot_crm.contacts.list, on crm.contact · HubSpot CRM

Example. Run it through check first: it validates the steps and prices them, and it is free.

Governance for 3CX

Destructive actions wait for a yes.

90 3CX actions are destructive. The first 10:

  • Delete a Users recordthree_cx.users.delete
  • Delete a Groups recordthree_cx.groups.delete
  • Delete a Contacts recordthree_cx.contacts.delete
  • Delete a Fax recordthree_cx.fax.delete
  • Delete a Fxs recordthree_cx.fxs.delete
  • Delete a Sbcs recordthree_cx.sbcs.delete
  • Delete a Queues recordthree_cx.queues.delete
  • Delete a Trunks recordthree_cx.trunks.delete
  • Delete a Backups recordthree_cx.backups.delete
  • Delete a Holidays recordthree_cx.holidays.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.

Illustrative. Scoped to 3CX only, capped at 2,000 upstream calls, every write confirmed, and the destructive ones approved by a named person.

Cost

What 3CX costs on actionlake.

Every 3CX action is one upstream call, the only thing actionlake bills. Searching, check, cost, account and any call 3CX 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 3CX MCP server, answered.

Is there a 3CX MCP server for Claude?

Yes. actionlake is an MCP gateway: a remote MCP server that gives Claude, or another MCP client, 576 3CX actions across users, backups, system status and trunks, through the same eight tools it uses for every other connector. actionlake is independent; it is not made or endorsed by 3CX.

What do I need to connect 3CX?

Client ID of the 3CX API service principal (Admin Console > Integrations > API; the DN you gave it) and API key shown once when the service principal was created. Plus your host. The free call account { op: "connections.requirements", service: "three_cx" } lists exactly what to paste.

Can an AI agent delete or change things in 3CX?

Only if its key allows it, and only with an explicit confirmation. 90 3CX actions are destructive, including delete a Users record, delete a Groups record and delete a Contacts record. 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 3CX API limit?

actionlake paces every call to the limits in the 3CX service file: 60 calls a minute per connection. Repeated reads are answered from cache (276 3CX actions can be), which never reaches 3CX.

What does a 3CX action cost?

One upstream call, the only unit actionlake bills. A list that pages bills one call per page (576 3CX actions page). Cache hits, searches, dry runs and calls 3CX 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 3CX API does it cover?

The 3CX XAPI v1 (OData, PBX 20.0.10.1479) and Call Control API (v20) at your 3CX instance's API base URL, which you enter when connecting. It is built from 3CX's documentation as read on 23 October 2026. 576 actions in 131 areas, each one in the signed service file (version 1.0.0).

Can I combine 3CX with my other systems?

Yes. ask joins 3CX to NetSuite or HubSpot CRM on the same customer and returns the answer rather than every row. 3CX maps crm.contact, which 192 other connectors also map.

Does actionlake keep my 3CX 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 3CX 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.
