Read and manage TidyCal scheduling: bookings, booking types, available timeslots, contacts and teams.
TidyCal ships in the w6w first-party pack. It declares 18 actions, 3 health checks, and the host runs its code in a sandbox that never sees the credential.
io.w6w.tidycalTidyCal is a scheduling tool — publish booking types, let people pick from your live availability, and get a booking with a contact attached — and this app covers that flow over TidyCal’s own REST API.
It lists booking types and their open timeslots, creates and cancels bookings, manages contacts, and covers TidyCal’s team features — team bookings, team booking types, and adding or removing team members. Reading real availability before booking means a workflow never has to reproduce TidyCal’s own scheduling logic, such as calendar conflicts, padding and minimum notice, itself.
Good for booking a call automatically once a lead reaches a certain stage elsewhere, canceling a booking when an external event says the meeting is no longer needed, syncing new bookings and contacts into a CRM, and coordinating team scheduling across a shared calendar link.
Three routes to the same 18 actions. The Workflow tab is generated from TidyCal's own manifest and carries its real ids, so it is copy-pasteable; the Code and CLI examples are the same call for any action on any app, so every app-specific value in them is a blank you fill in.
booking-get Fetch one booking by ID, including its contact, question answers and payment.
booking-list List the connected account's bookings, optionally filtered by date window.
booking-type-list List the account's booking types. The only endpoint that returns booking type IDs.
contact-create Create a contact. Requires a TidyCal lifetime subscription — otherwise TidyCal answers 402.
contact-list List the account's contacts. Includes each contact's captured IP address.
team-booking-list List a team's bookings, filtered by date window, booker email, host or status.
team-booking-type-list List a team's booking types. The personal booking-type list never includes these.
team-user-list List the members of a team. The `id` on each row is a team-membership ID.
timeslot-list List bookable timeslots for a booking type within a UTC window, after TidyCal applies availability, existing bookings, calendar conflicts and padding.
A workflow step names the app and the action, and the editor fills in the
connection when you pick one. This is the Step shape from the
workflow spec, carrying TidyCal's real ids.

Every app-specific value here is a blank you have to fill in. An
app action is reached through the connection that authenticates it, so the
address is a connection id, not the app id — and connections belong to your account,
so a public page cannot know yours. Create one for TidyCal, then fill in
the three blanks: conn_YOUR_CONNECTION_ID, the action key, and the
parameters that action declares. The call itself is real — the shape is transcribed
from the studio's own snippet builder, which prints the same kind of blanks — but
nothing in it is specific to TidyCal. The Workflow tab is where this app's
real ids are.

One MCP endpoint exposes every app, function and workflow the caller is entitled to, as tools it can discover and run. Access is granted per team while we onboard.
One tool call{
"name": "w6w_invoke",
"arguments": {
"ref": "app:io.w6w.tidycal#booking-create",
"input": {
"bookingType": "<bookingType>",
"name": "<name>",

}
}
}
Every tool names its target with a single ref. The
app: form above doesn't name a connection at all — the
host resolves which of the caller's TidyCal connections to sign
with, and refuses rather than guesses when the answer is ambiguous.
The token is attached host-side, at the moment of the call. It is never a tool argument, never in the model's context, and never in a transcript — so a prompt injection has nothing to exfiltrate.
Tools are derived per end user from what that person has actually connected and is entitled to — not one shared bot identity carrying the union of everyone's access.
Multi-step work runs on the workflow engine and returns a run handle the agent can poll — retries, branching and state survive the conversation that started them.
TidyCal's declared health checks are on the surface too, so an agent can tell "the vendor is down" from "your credential expired" before it burns a retry on either.
The MCP surface is part of the hosted platform. TidyCal itself is MIT, and the runtime that executes it is source-available (FSL).
TidyCal declares its own checks, so its health is a property of the app rather than something the host guesses at.
Unauthenticated GET https://tidycal.com/api/me. A 401 {"message":"Unauthenticated."} passes — it proves the API router and auth middleware are serving. Credential validity is the derived auth:* checks' job.
