Cotlet runs 12 Markate tools hosted, over MCP for agents and REST for scripts, in your own Markate login. Your AI agent drafts estimates from inquiries, schedules and moves work orders, invoices finished jobs and chases what is overdue. Sign in to Markate once in your own Cloud Browser. No API request, no developer. - Free 7-day trial, no card - Unofficial, not affiliated with Markate - Page: https://cotlet.dev/integrations/markate-api-mcp-server ## What can your AI agent do in Markate? - Draft estimates from inquiries - Schedule one-off and recurring jobs - Move a rained-out day - Invoice finished work orders - Chase overdue invoices - Find customers and their history ## Does Markate have an MCP server or an API? - Markate asks for your business, industry and purpose before it approves API access. - Markate documents no webhooks on its developer page. - Markate has no connector in the ChatGPT apps directory or in Claude. | What you need | Markate API | Zapier app | Cotlet | |---|---|---|---| | Customers and estimates | After approval | Some triggers and actions | Yes | | Schedule or move a job | After approval | Limited | Yes, after your OK | | Invoices and overdue list | After approval | Limited | Yes | | Ask in ChatGPT or Claude | No | No | Yes | | Developer needed | Yes | Zap setup | No | Checked 8 Nov 2026.

We never keep your Markate password, and no estimate, invoice or schedule change reaches a customer until you approve it. ## How to connect Markate to your AI agent 1. **Sign in to Markate in a Cloud Browser.** Create a Cotlet account, open Markate in its Cloud Browser, sign in with your Markate business login and press Enable for agents. 2. **Add the Cotlet address.** Enter https://cotlet.dev/mcp/v1 as the MCP server or connector URL in your agent. 3. **Let the agent in.** Chat apps open a Cotlet sign-in page. Editors, n8n and scripts send an API key made in the console. Markate shares the address `https://cotlet.dev/mcp/v1` with every other app you enable, so one connector covers them all. Turned Markate on after connecting? Refresh the connector and the 12 tools appear. Claude: ``` Settings > Connectors > Add custom connector URL: https://cotlet.dev/mcp/v1/connect Claude Code: claude mcp add --transport http cotlet \ https://cotlet.dev/mcp/v1 \ --header "Authorization: Bearer $COTLET_API_KEY" ``` ChatGPT: ``` Settings > Apps & Connectors > Create MCP server URL: https://cotlet.dev/mcp/v1/connect Authentication: OAuth ``` Cursor: ``` // ~/.cursor/mcp.json { "mcpServers": { "cotlet": { "url": "https://cotlet.dev/mcp/v1", "headers": { "Authorization": "Bearer ${env:COTLET_API_KEY}" } } } } ``` Codex: ``` # ~/.codex/config.toml [mcp_servers.cotlet] url = "https://cotlet.dev/mcp/v1" bearer_token_env_var = "COTLET_API_KEY" ``` n8n: ``` MCP Client Tool (inside an AI Agent) Transport: HTTP Streamable URL: https://cotlet.dev/mcp/v1 Auth: Bearer, Tool: markate_read ``` Make, Zapier: ``` Make: MCP Client > Call a tool Zapier: MCP Client by Zapier > Run Tool Server URL: https://cotlet.dev/mcp/v1 Token: Tool: markate_write ``` ## All 12 Markate MCP tools ### Customers Search matches name, phone, email and street, so a returning customer is found before a duplicate is made. - **List customers** (`list_customers`, read): Customers, searchable by name, phone, email or address. - **Get customer** (`get_customer`, read): One customer with estimates, work orders and invoices. - **Create customer** (`create_customer`, write): Adds a new customer. ### Estimates Drafts use your own items and prices. Sending waits for your OK. - **Create estimate** (`create_estimate`, write): Drafts an estimate with line items for a customer. - **Send estimate** (`send_estimate`, write, asks first): Emails or texts an estimate to the customer. ### Work orders One-off and recurring jobs on the schedule. New jobs and moves wait for your OK; your notification settings decide what the customer hears. - **List work orders** (`list_work_orders`, read): Work orders for a date range, by employee or status. - **Schedule work order** (`schedule_work_order`, write, asks first): Creates a work order on the schedule, once or recurring. - **Reschedule work order** (`reschedule_work_order`, write, asks first): Moves a work order to a new time or employee. ### Invoices and tasks Draft invoices and tasks reach no one, so they run at once. Sending an invoice waits for your OK. - **Create invoice** (`create_invoice`, write): Drafts an invoice from a work order or line items. - **Send invoice** (`send_invoice`, write, asks first): Emails or texts an invoice with its payment link. - **List unpaid invoices** (`list_unpaid_invoices`, read): Open and overdue invoices with customer and age. - **Add task** (`add_task`, write): Adds a task for you or an employee.

No password. - **What your agent gets.** The 12 Markate tools, never the session cookie. - **What the session sees.** What your login sees: customers, estimates, schedule, invoices. - **What no tool touches.** Card payments, refunds, payroll, marketing sends, deletes. - **If Markate signs you out.** You sign in again yourself, in the same Cloud Browser. - **How to cut access.** Disable for agents, reset the browser, or change your Markate password. Cotlet never types your password: you sign in yourself, and the agent only uses the session. Our site scores A+ on Qualys SSL Labs, securityheaders.com and Mozilla Observatory ([live results](https://cotlet.dev/security.md)). ## What happens when Markate changes? - **12 h** between tests of the Markate reads - **24 h** between tests of sends a customer would notice - **$0** for a call to a Markate tool paused for repair When Markate moves a button on the schedule or renames a sales screen, we fix the tool and your agent calls it the same way. [status.cotlet.dev](https://status.cotlet.dev) checks the site, console and API every 3 minutes. ## Approvals, undo and mistakes 1. **Reads tomorrow's work orders.** For the employee and the weather you name. 2. **Finds free times.** On the day you want the jobs moved to. 3. **Proposes the moves.** And lists what does not fit. 4. **Waits, then moves.** The batch shows up in your Cotlet console first. | Action | Undo | |---|---| | Schedule a work order | Yes, delete or move it in Markate | | Move a work order | Move it back; a notice already sent stays sent | | Send an estimate or invoice | No, it is in the customer's inbox; void it in Markate | | Add a customer, draft or task | Yes, edit it in Markate | 4 of 12 tools ask first: send_estimate, schedule_work_order, reschedule_work_order, send_invoice. New customers, draft estimates, draft invoices and tasks reach no customer, so they run at once. You can turn the wait off per tool once you trust a routine. MCP call: ``` { "name": "schedule_work_order", "arguments": { "customer_id": "C-21940", "title": "Window cleaning, 22 panes", "start": "2026-11-12T13:00", "employee": "Luis", "repeat": "Monthly" } } ``` REST: ``` curl -X POST https://cotlet.dev/api/v1/markate/customers/C-21940/work-order/schedule \ -H "Authorization: Bearer $COTLET_API_KEY" \ -H "Content-Type: application/json" \ -d '{"title":"Window cleaning, 22 panes","start":"2026-11-12T13:00","employee":"Luis","repeat":"Monthly"}' ``` Response: ``` { "work_order_id": "WO-5541", "customer": "Marcus Delgado", "employee": "Luis", "start": "2026-11-12T13:00", "repeat": "Monthly", "status": "Scheduled" } ``` A cron job or n8n flow can call the same tools over REST at `/api/v1/markate` with the same key and price, in JSON. Failed calls are free. Each tool row above shows its REST path. ## How much does the Markate MCP server cost? **About $42 a month** for a home service business with 4 employees, 7,260 credits. Your Markate plan stays as it is. | Job | Calls | Credits | |---|---|---| | Estimate from an inquiry | 3 × 40 | 1,200 | | Work order scheduled or moved | 2 × 90 | 1,800 | | Invoices for finished jobs, daily | 6 × 22 | 1,320 | | Overdue invoices chased, weekly | 6 × 4 | 240 | | Invoice sent | 1 × 120 | 1,200 | | Cloud Browser, 30 days | | 1,500 | | Total | | 7,260 | - Free 7-day trial, no card - 10 credits per successful call, MCP or REST - 50 credits a day for the Cloud Browser - Works on your current Markate plan Markate publishes no job counts, so the month is our example. Dollars at the $29 pack rate. ## Markate MCP server on GitHub, Zapier or hosted: which to use | Option | What it does | Where it stops | |---|---|---| | Markate API | Customers, estimates, work orders and invoices for your own developer. | Key only after an approved request; you build and host the code. | | Zapier app | Triggers and actions between Markate and other apps. | Zaps to set up per job; no questions in plain words. | | By hand | Every screen of Markate, one job at a time. | Your office's time. | If you already have an approved Markate API key and a developer, building on the API is cheaper for simple syncs.

Sign up free at https://cotlet.dev, open Markate under Integrations in the console and sign in to Markate in its Cloud Browser. The trial starts with your first app and asks for no card. ### How do I connect Markate to ChatGPT or Claude? Sign up at cotlet.dev, log in to Markate once in its Cloud Browser and add Cotlet to ChatGPT or Claude, following the steps in your console. No API key is needed. ChatGPT and Claude then work in your Markate account through Cotlet, in their phone apps too. ### What can ChatGPT do in Markate? With Cotlet, ChatGPT, Claude and other AI agents handle jobs like these in Markate: turn an inquiry into an estimate; book recurring service; move a rained-out day. You ask in plain words, and anything that reaches other people waits for your OK first. ### Is there an official ChatGPT or Claude app for Markate? No. Markate has no ChatGPT or Claude connector of its own and Markate has no official MCP server (checked 8 Nov 2026). Cotlet is an independent one that works in ChatGPT, Claude, Cursor and any MCP client, on your signed-in account. ### Can ChatGPT create estimates in Markate? Yes, with Cotlet. ChatGPT finds or adds the customer and drafts the estimate from your items and prices. Sending it to the customer waits for your OK by default. ### Can ChatGPT schedule work orders in Markate? Yes, with Cotlet. ChatGPT puts one-off or recurring jobs on the schedule with the employee you name, and moves jobs when the weather or a sick day changes the plan, after your OK. ### Can ChatGPT send invoices in Markate? Yes, with Cotlet. ChatGPT drafts invoices for completed work orders, sends them with the payment link after your OK and lists what is overdue. ### Do I need Markate API access to use Cotlet? No. Cotlet works through your own Markate login, so you do not need to request and wait for an API key. It can do what your login can do in Markate. ### Does it work with Markate's own AI receptionist? Yes. Kate answers calls inside Markate; Cotlet lets ChatGPT or Claude work in the same account. A job Kate books shows up for your agent like any other work order. ### Is the MCP server different from the REST API? Only in how it is called. Both carry the same 12 tools, inputs, answers, API key and price. Agents use MCP; scripts and HTTP steps use REST. ### Is Cotlet affiliated with Markate? No. Cotlet is independent and not affiliated with Markate. --- Give your AI agents your signed-in browser. **Product:** [Integrations](https://cotlet.dev/integrations.md) · [How it works](https://cotlet.dev/how-it-works.md) · [Pricing](https://cotlet.dev/pricing.md) · [Security](https://cotlet.dev/security.md) **Resources:** [Blog](https://cotlet.dev/blog.md) · [API docs](https://cotlet.dev/docs.md) · [Help center](https://cotlet.dev/help.md) · [Changelog](https://cotlet.dev/changelog.md) · [GitHub](https://github.com/cotletdev/cotlet) **Solutions:** [For developers](https://cotlet.dev/for-developers.md) · [For automation agencies](https://cotlet.dev/for-agencies.md) **Company:** [About](https://cotlet.dev/about.md) · [AI info: company facts](https://cotlet.dev/ai-info.md) · [Contact](https://cotlet.dev/contact.md) **Legal:** [Terms of service](https://cotlet.dev/terms) · [Privacy policy](https://cotlet.dev/privacy) · [Refund policy](https://cotlet.dev/refunds) · [Acceptable use](https://cotlet.dev/acceptable-use) · [Cookie policy](https://cotlet.dev/cookies) · [DPA](https://cotlet.dev/dpa) · [Subprocessors](https://cotlet.dev/subprocessors) **Elsewhere:** [Status page](https://status.cotlet.dev) · [Cotlet on GitHub](https://github.com/cotletdev) · [Cotlet on X](https://x.com/cotletdev) · [Cotlet on LinkedIn](https://www.linkedin.com/company/cotletdev) · [Cotlet on Product Hunt](https://www.producthunt.com/products/cotlet) · [Cotlet on Crunchbase](https://www.crunchbase.com/organization/cotlet) · [Cotlet on SaaSHub](https://www.saashub.com/cotlet) Cotlet.dev is built by Bart Krawczyk and Jake Slugocki, the founders of Take Group sp. z o.o., ul.
