Official API

Does Mariana Tek have an official API?

Yes, but gated: Mariana Tek has APIs (Customer, Studio, Admin, Webhooks and more), and credentials go only to integration partners who sign the Developer Tools Terms of Service and to developers working with a single studio, with the studio owner included in the request; no official MCP server exists (checked 11 Oct 2026). A technical review of about 1 to 3 weeks may follow, and reporting data and Stripe data are not available through the API.

Common use cases

What can an AI agent do in Mariana Tek?

Cotlet is best for boutique studio owners and front desk teams who want an AI agent to book, cancel, check in and credit customers in Mariana Tek without running or fixing a server.

Check in a class roster Runs: Daily

Check in everyone in the 6pm HIIT class except the two who texted they are not coming. Your agent calls list_classes, get_class_roster and check_in_customer.
Book a customer into a class from a message

Book jamie@example.com into Saturday 9am Pilates Sculpt at Downtown with her membership. If it is full, put her on the waitlist and tell me. Your agent calls find_customer, get_customer, list_classes, book_reservation and add_to_waitlist.
Cancel reservations without a late cancel fee

Chris is travelling 19 to 23 Oct. Cancel all his reservations that week without a late cancel fee and note why on his account. Your agent calls find_customer, list_customer_reservations, cancel_reservation and add_customer_note.
Give complimentary credits to a whole class

Sam's 6pm Ride tonight lost power after 20 minutes. Give everyone who was checked in one complimentary Class Credit, expiring in 30 days, reason "Class cut short". Your agent calls get_class_roster, list_customer_credits and give_complimentary_credits.
Assign a substitute instructor and email the class Runs: Weekly

Alex is sick. Put Taylor Kim in as sub on all of Alex's classes Thursday and email each class that Taylor is teaching. Your agent calls list_locations, list_classes, assign_substitute and message_class.
Daily roster and credit check Runs: Daily

Who is on the roster and the waitlist for tomorrow's 7am ride? Flag anyone without a valid credit. Your agent calls list_classes, get_class_roster and list_customer_credits.

Endpoints

What is the Mariana Tek API?

Cotlet's Mariana Tek API exposes 15 endpoints for your own Mariana Tek account: list locations, list classes, get class roster, find customer, get customer, list customer reservations, list customer credits, book reservation, add to waitlist, cancel reservation, check in customer, give complimentary credits, add customer note, assign substitute and message class. The list_locations endpoint returns your studio locations with address and time zone. Each endpoint takes simple JSON inputs like customer_id, class_id or instructor and works both as an MCP tool for agents and as a REST call for scripts.

Setup

How do I connect Mariana Tek to Claude Code, Codex or Cursor?

Connecting Mariana Tek takes three steps: request access, sign in to Mariana Tek once, then add one MCP server or call the REST API with the same key.

MCP REST API

1
Create an account

Sign up and add Mariana Tek in the console. Your API key is there too.
2
Sign in to Mariana Tek once

Open the connect page from the console and sign in to Mariana Tek the way you always do. We keep the session, never your password, and you can revoke it anytime.
3
Add Cotlet to your agent
Claude Code Cursor Codex
Claude Code
```
claude mcp add --transport http cotlet \
  https://cotlet.dev/mcp/v1 \
  --header "Authorization: Bearer $COTLET_API_KEY"
```
Cursor
```
{
  "mcpServers": {
    "cotlet": {
      "url": "https://cotlet.dev/mcp/v1",
      "headers": {
        "Authorization": "Bearer ${COTLET_API_KEY}"
      }
    }
  }
}
```
Codex
```
# ~/.codex/config.toml
[mcp_servers.cotlet]
url = "https://cotlet.dev/mcp/v1"
bearer_token_env_var = "COTLET_API_KEY"
```
Paste the snippet for your client. The same server and key serve every app you connect, so you do this once.
4
Ask your agent
Prompt
```
Check in everyone in the 6pm HIIT class except the two who texted they are not coming.
```
Ask in plain words. Your agent finds the Mariana Tek tools on the server and calls them for you; anything that reaches other people waits for your OK unless you switch that off for a tool.

1
Export your API key
Shell
```
export COTLET_API_KEY="cotlet_..."
```
Your scripts use the same API key as your agent. Keep it in an environment variable, never in your code.

Call a tool

curl

curl https://cotlet.dev/api/v1/mariana-tek/book_reservation \
  -H "Authorization: Bearer $COTLET_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"class_id":"418203","customer_id":"90517","payment_option_id":"mbr_2231"}'

Every tool is a POST endpoint at /api/v1/mariana-tek/{tool}. Send its parameters as JSON, exactly as listed in the endpoints above.

Read the result

Example response · book_reservation

{
  "reservation_id": "7710342",
  "class_id": "418203",
  "class": "Pilates Sculpt",
  "start": "2026-10-17T09:00:00-04:00",
  "customer": "Jamie Park",
  "payment_used": "Unlimited Monthly",
  "spot": "1",
  "status": "pending"
}

You get plain JSON back, ready for your script. A failed call costs nothing.

Alternatives

Is there a Mariana Tek MCP server on GitHub?

Mariana Tek has no official MCP server and we found no Zapier or Make app for it. Hosted scrapers that read studio data exist. For actions, the route is your own integration on the official API, which needs approval, or doing the work by hand in Mariana Tek Admin. Cotlet hosts the actions for you, under your own Admin login.

Cotlet compared with a Own partner integration
	Own partner integration	Cotlet
Setup	Partner survey and signed Developer Tools ToS, or a request that includes the studio owner, then a sandbox and credentials	Request access, sign in to Mariana Tek Admin once in your browser, add one MCP server or API key
Approval	Technical review of about 1 to 3 weeks for many integrations, with a screen recording	None from Mariana Tek: your agent acts with your own Admin role
When Mariana Tek changes	You maintain the code	Our team tests it daily and fixes it for you; failed calls are free
Your session	Your code stores API credentials or tokens	Encrypted in an EU vault, limited to the actions you allow, revoked in one click
When the session expires	Your code refreshes tokens or rotates keys	Your agent gets a link to sign in again
Where it runs	Your own server	Hosted: Claude Code, Codex, Cursor, n8n and scripts, also on a schedule
Price	No published API fee; your build and review time	Free 7-day trial with 5,000 credits, then credits per call

Which one fits you

Pick Cotlet if

you are not a developer, or you do not want to maintain a server
you need it to keep working when Mariana Tek changes, without checking it yourself
your agent or a script should run it on a schedule, also while your computer is off

Pick an open-source server if

you are comfortable installing, updating and fixing it yourself
you want the session to stay on your own computer
you only need it now and then, from one MCP client

mariana-tek.txt

Yes, but gated: Mariana Tek has APIs (Customer, Studio, Admin, Webhooks and more), and credentials go only to integration partners who sign the Developer Tools Terms of Service and to developers working with a single studio, with the studio owner included in the request; no official MCP server exists (checked 11 Oct 2026). A technical review of about 1 to 3 weeks may follow, and reporting data and Stripe data are not available through the API.
Cotlet provides a hosted MCP server and REST API for Mariana Tek: 15 tools (7 read, 8 write).
Access       Request access at https://cotlet.dev/app/signup?app=mariana-tek; we email the API key.

MCP server   https://cotlet.dev/mcp/v1
REST base    https://cotlet.dev/api/v1/mariana-tek
Auth         Authorization: Bearer <COTLET_API_KEY>. Listing endpoints and schemas needs no key; calling an endpoint needs one.
Tools        list_locations, list_classes, get_class_roster, find_customer, get_customer, list_customer_reservations, list_customer_credits, book_reservation, add_to_waitlist, cancel_reservation, check_in_customer, give_complimentary_credits, add_customer_note, assign_substitute, message_class
Confirm      book_reservation, add_to_waitlist, cancel_reservation, check_in_customer, give_complimentary_credits, assign_substitute, message_class (by default the user approves each call; the user can switch this off per tool, e.g. for scheduled automations)
Markdown     https://cotlet.dev/integrations/mariana-tek-api-mcp-server.md

How access works:
1. The user requests access at https://cotlet.dev/app/signup?app=mariana-tek (Mariana Tek is pre-selected). Each request is reviewed and the API key is sent by email.
2. The user signs in to Mariana Tek once in a browser. An agent cannot do this step.
3. The API key goes into the MCP client or the REST call as a bearer token.

Fits: people who want a hosted Mariana Tek server that someone else maintains, including non-developers.

Policy: Cotlet never stores passwords, never solves CAPTCHAs, never bypasses MFA.
Company: legal details in the Terms of service at https://cotlet.dev/terms. Contact contact@cotlet.dev.
Session: the user signs in to Mariana Tek in a browser; Cotlet keeps only the session, AES-256 encrypted, revocable in the dashboard at any time.
Terms: the user stays responsible for following Mariana Tek's terms; Cotlet is not affiliated with Mariana Tek.

Automations

Can Mariana Tek automations run on a schedule in n8n, Make or Zapier?

Yes. Cotlet does not replace your automation platform: it gives it a Mariana Tek connection it does not have, with the same API key as your agent. Write actions ask for your OK by default; switch that off in your dashboard for the tools you choose, for example to check in a class roster, and the schedule runs on its own. Cotlet runs in the cloud, so it keeps going while your computer is off.

About Cotlet

How Cotlet holds your access

Cotlet hosts MCP servers and REST APIs for apps with no usable API. Your agent works in your own Mariana Tek account.

Company details: The legal name, address and registration numbers of the company behind Cotlet are in the Terms of service. Terms
Your session: You sign in to Mariana Tek yourself, in your browser. We keep only the session, never your password: encrypted with AES-256 in an EU vault, isolated to your account and used only when your agent calls a Mariana Tek tool you allowed. When it expires, your agent gives you a link to sign in again. Security
Revoking access: Disconnect Mariana Tek in your dashboard: the session is deleted and access ends at once. Actions that reach other people wait for your OK unless you switch that off per tool.
What we never do: Store passwords, solve CAPTCHAs or bypass MFA.
Mariana Tek's terms: You use your own Mariana Tek account and stay responsible for following Mariana Tek's terms. Cotlet is independent and not affiliated with Mariana Tek. Terms
Contact: Questions about the company, security or an app: contact@cotlet.dev

About Cotlet

Frequently asked questions

How do I get access?

Request access and pick Mariana Tek. Cotlet reviews each request and emails you your API key.

Do I need to be technical?

No. You sign in to Mariana Tek once in your browser and paste one command into your agent, or one URL into n8n. Your agent can walk you through it. There is no server to install, update or fix.

Is a hosted server safe? My Mariana Tek session would leave my computer.

Cotlet keeps your Mariana Tek session encrypted with AES-256 in an EU vault, isolated to your account and used only for the tools you allow: read only, or read and write. The AI model never sees it, and you revoke it in one click. A local server keeps the same session in a file on your computer, readable by any program you run, and needs a fresh sign-in whenever it expires.

Do I need API access from Mariana Tek to use Cotlet?

No. Cotlet signs in to Mariana Tek Admin with your own account, so it does not use the Developer Tools ToS or the technical review that Mariana Tek requires for API credentials (Mariana Tek developer guides, checked 11 Oct 2026). Your agent can only do what your own Admin role allows.

Can my agent waive a late cancel fee?

Only if your own Mariana Tek role has the permission to grace a cancel. Staff without it do not see the cancel without fee option in Mariana Tek, and cancel_reservation cannot waive the fee for them either (Mariana Tek help center).

Can my agent post or send messages in Mariana Tek without asking me?

No. Every call to book_reservation, add_to_waitlist, cancel_reservation, check_in_customer, give_complimentary_credits, assign_substitute or message_class waits for your OK by default. For scheduled automations you can switch confirmation off per tool in your dashboard, for example only for approvals. add_customer_note runs without asking, because it sends nothing to anyone and one call undoes it.

Can I use the Mariana Tek API in n8n?

Yes. Add https://cotlet.dev/mcp/v1 with your API key in n8n's MCP Client node, or call https://cotlet.dev/api/v1/mariana-tek/{tool} from the HTTP Request node.
