--- title: "Calendly MCP server for AI agents - actionlake" description: "Give Claude 65 Calendly actions through one MCP server: contacts, meeting recaps. Your agent never holds the credential. 100,000 calls a month free." canonical: https://actionlake.com/connectors/calendly updated: 2026-10-22 --- Connectors · Marketing & media # Calendly MCP server for AI agents. actionlake is an MCP gateway: one remote MCP server that connects Claude and other MCP clients to Calendly and the rest of your systems. It gives your agent 65 Calendly actions (43 reads, 13 writes and 9 that wait for a confirmation) and holds the Calendly credential itself, so the agent never does. It paces Calendly's limits and records every call. Connecting Calendly needs your own Calendly OAuth app and one admin sign-in. [Connect Calendly 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: "calendly.scheduled_events.list", intent: "check which Calendly account is connected" } # List Events · read · 1 upstream call ``` - 65 actions in one signed file - 43 read look, never change - 13 write create and update - 9 wait for a yes destructive, confirmed first Set up ## Connect Calendly 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 Calendly. OAuth 2.0, authorization code with PKCE. You register your own OAuth app with Calendly, an admin signs in once, and you paste the app's client id and secret and the tokens from that sign-in; actionlake renews the access token from then on. actionlake stores what you paste write-only, sealed under your tenant's key. Before the first sign-in, Calendly needs an OAuth app of your own, registered in its developer portal. actionlake has no Calendly app to lend you. - `access_token` Access token from one sign-in with your own OAuth app - `refresh_token` Refresh token from the same sign-in; the access token is renewed from it - `client_id` Calendly OAuth client id (developer.calendly.com > My apps > your web OAuth app) - `client_secret` Calendly OAuth client secret (shown once, when the app is created) ``` account { op: "connections.requirements", service: "calendly" } # 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: "calendly.scheduled_events.list" } # list events · read · 1 upstream call check { action: "calendly.contacts.create", input: { … } } # free: inputs, permissions, cost and confirmations, nothing sent ``` Calendly at a glance **Sign-in** OAuth 2.0, authorization code with PKCE.

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 free call account { op: "connections.requirements", service: "calendly" } lists exactly what to paste. **Can an AI agent delete or change things in Calendly?** Only if its key allows it, and only with an explicit confirmation. 9 Calendly actions are destructive, including delete Contact, cancel Event and delete Webhook Subscription. 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 Calendly API limit?** actionlake paces every call to the limits in the Calendly service file: 500 calls a minute per connection. Repeated reads are answered from cache (43 Calendly actions can be), which never reaches Calendly. **What does a Calendly action cost?** One upstream call, the only unit actionlake bills. A list that pages bills one call per page (16 Calendly actions page). Cache hits, searches, dry runs and calls Calendly 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 Calendly API does it cover?** The Calendly API v2 (OpenAPI 3.1.0) at api.calendly.com. It is built from Calendly's documentation as read on 22 October 2026. 65 actions in 30 areas, each one in the signed service file (version 1.0.0). **Does actionlake keep my Calendly 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 Calendly 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. ## More connectors like Calendly Shares the most action names with - [Cvent 13](https://actionlake.com/connectors/cvent) - [SurveyMonkey 12](https://actionlake.com/connectors/surveymonkey) - [Phrase Strings 11](https://actionlake.com/connectors/phrase-strings) - [Livestorm 10](https://actionlake.com/connectors/livestorm) - [Luma 10](https://actionlake.com/connectors/luma) - [SurveySparrow 9](https://actionlake.com/connectors/surveysparrow) Joins with, on shared entities - [HaloPSA 4](https://actionlake.com/connectors/halopsa) - [Planning Center 4](https://actionlake.com/connectors/planning-center) - [Odoo 4](https://actionlake.com/connectors/odoo) - [Microsoft Dynamics 365 4](https://actionlake.com/connectors/microsoft-dynamics-365) - [Close 4](https://actionlake.com/connectors/close) - [Recruit CRM 4](https://actionlake.com/connectors/recruit-crm) Browse - [All Marketing & media connectors](https://actionlake.com/connectors/category/marketing-and-media) - [All connectors](https://actionlake.com/connectors) - [How actionlake compares](https://actionlake.com/compare) actionlake is independent.
