Cal.com MCP server for AI agents.

actionlake is an MCP gateway: one remote MCP server that connects Claude and other MCP clients to Cal.com and the rest of your systems. It gives your agent 397 Cal.com actions (172 reads, 161 writes and 64 that wait for a confirmation) and holds the Cal.com credential itself, so the agent never does. It paces Cal.com'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 Cal.com 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 Cal.com.

    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_keyCal.com API key (Settings > Security; live keys start with cal_live_, test keys with cal_), or an OAuth access token
    account { op: "connections.requirements", service: "cal_com" }
# 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: "cal_com.teams.list" }# get teams · read · 1 upstream callcheck { action: "cal_com.org_users.create", input: { … } }# free: inputs, permissions, cost and confirmations, nothing sent

Top actions

The Cal.com API, shaped for agents.

The ids your agent types, what each does, and the one name it shares with other systems. 30 of Cal.com's 30 action names are shared with at least one other connector, so an agent learns them once.

Prompts to paste into Claude.

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

  1. Readread

    What is on the Cal.com calendar this week?

    callscal_com.bookings.list

  2. Writewrite

Governance for Cal.com

Destructive actions wait for a yes.

64 Cal.com actions are destructive. The first 10:

  • Delete a usercal_com.org_users.delete
  • Delete a teamcal_com.teams.delete
  • Delete an organization rolecal_com.org_roles.delete
  • Cancel a bookingcal_com.bookings.cancel
  • Delete a webhookcal_com.webhooks.delete
  • Delete an event typecal_com.event_types.delete
  • Charge creditscal_com.credits.charge
  • Add permissions to an organization role (single or batch)cal_com.org_role_permissions.add
  • Add permissions to an organization team role (single or batch)cal_com.org_team_role_permissions.add
  • Delete an Eventcal_com.events.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.

Questions

The Cal.com MCP server, answered.

Is there a Cal.com MCP server for Claude?

Yes. actionlake is an MCP gateway: a remote MCP server that gives Claude, or another MCP client, 397 Cal.com actions across bookings, insights, calendars and event registrations, through the same eight tools it uses for every other connector. actionlake is independent; it is not made or endorsed by Cal.com.

What do I need to connect Cal.com?

Cal.com API key (Settings > Security; live keys start with cal_live_, test keys with cal_), or an OAuth access token. The free call account { op: "connections.requirements", service: "cal_com" } lists exactly what to paste.

Can an AI agent delete or change things in Cal.com?

Only if its key allows it, and only with an explicit confirmation. 64 Cal.com actions are destructive, including delete a user, delete a team and delete an organization role. 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 Cal.com API limit?

actionlake paces every call to the limits in the Cal.com service file: 120 calls a minute per connection. Repeated reads are answered from cache (167 Cal.com actions can be), which never reaches Cal.com.

What does a Cal.com action cost?

One upstream call, the only unit actionlake bills. A list that pages bills one call per page (397 Cal.com actions page). Cache hits, searches, dry runs and calls Cal.com 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 Cal.com API does it cover?

The Cal.com API v2 (OpenAPI 3.0.0, per-endpoint cal-api-version header) at api.cal.com/v2. It is built from Cal.com's documentation as read on 22 October 2026. 397 actions in 107 areas, each one in the signed service file (version 1.0.0).

Does actionlake keep my Cal.com 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 Cal.com 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.
