MCP

Give your agent Cal.com tools

Every Cal.com action is exposed as an MCP tool on Pipedream's remote server. Point a client at it with your end user's ID and Connect resolves that user's Cal.com account for each tool call — you store no tokens.

// accessToken: mint a short-lived token with the Connect SDK — see the MCP guide
const transport = new StreamableHTTPClientTransport(

API PROXY

Call the Cal.com API directly

For an endpoint with no pre-built tool, the Connect proxy forwards your request to the Cal.com API with the connected user's credentials attached. You store no tokens and write no refresh logic.

Pipedream Connect

const resp = await pd.proxy.get({
  externalUserId: "{external_user_id}", // any stable ID for this user in your system
  accountId: "apn_xxxxxxx",
  url: "https://api.example.com/v1/me",
})

// Any allowed Cal.com endpoint works here. Pipedream attaches the
// connected account's credentials to the outgoing request.

# The path segment is the target URL, URL-safe base64 encoded:
# https://api.example.com/v1/me

curl "https://api.pipedream.com/v1/connect/{project_id}/proxy/aHR0cHM6Ly9hcGkuZXhhbXBsZS5jb20vdjEvbWU?external_user_id={external_user_id}&account_id=apn_xxxxxxx" \
  -H "Authorization: Bearer {access_token}" \
  -H "x-pd-environment: production"

SDK

Run Cal.com actions from your backend

Connect a user's Cal.com account once, then run Cancel Booking on their behalf from your own code — TypeScript, Python, or plain HTTP.

Pipedream Connect

import { PipedreamClient } from "@pipedream/sdk"

const pd = new PipedreamClient({
  projectId: process.env.PIPEDREAM_PROJECT_ID!,
  clientId: process.env.PIPEDREAM_CLIENT_ID!,
  clientSecret: process.env.PIPEDREAM_CLIENT_SECRET!,
  projectEnvironment: "production",
})

const result = await pd.actions.run({
  id: "cal_com-delete-booking",
  externalUserId: "{external_user_id}", // any stable ID for this user in your system
  configuredProps: {
    cal_com: { authProvisionId: "apn_xxxxxxx" },
    bookingId: "Booking ID",
    cancellationReason: "Cancellation Reason",
  },
})

from pipedream import Pipedream

pd = Pipedream(
    client_id="{oauth_client_id}",
    client_secret="{oauth_client_secret}",
    project_id="{project_id}",
    project_environment="production",
)

result = pd.actions.run(
    id="cal_com-delete-booking",
    external_user_id="{external_user_id}",  # any stable ID for this user in your system
    configured_props={
        "cal_com": {"authProvisionId": "apn_xxxxxxx"},
        "bookingId": "Booking ID",
        "cancellationReason": "Cancellation Reason",
    },
)

curl -X POST https://api.pipedream.com/v1/connect/{project_id}/actions/run \
  -H "Content-Type: application/json" \
  -H "X-PD-Environment: production" \
  -H "Authorization: Bearer {access_token}" \

    }
  }'
