Its only key is for Zapier on the new subscription plan, and it "is limited to importing, updating and syncing Contacts" (17hats help, checked 9 Nov 2026). Cotlet runs 9 17hats tools hosted, over MCP for agents and REST for scripts, in your own 17hats login. Your AI agent logs enquiries as leads, sends quotes, contracts and invoices, records payments and plans your day. Sign in to 17hats once in your own Cloud Browser. No API, no new plan. - Free 7-day trial, no card - Unofficial, not affiliated with 17hats - Page: https://cotlet.dev/integrations/17hats-api-mcp-server ## What can your AI agent do in 17hats? - Log enquiries as leads - Send quotes and contracts - Send invoices - Record payments - Plan the day's to-dos - See the week's projects ## Does 17hats have an MCP server or an API? - 17hats' Zapier key works only on the new subscription plan. - The Zapier app cannot create projects, quotes or invoices. - 17hats has no connector in the ChatGPT apps directory or in Claude. | What you need | 17hats API | Zapier app | Cotlet | |---|---|---|---| | Contacts and leads | No API | Contacts, new plan | Yes | | Projects | No API | No | Yes | | Quotes, contracts, invoices | No API | No | Yes, after your OK | | Ask in ChatGPT or Claude | No | No | Yes | | Plan needed | None | New plan | Any | Checked 8 Nov 2026.

We never keep your 17hats password, and no quote, contract, invoice or payment goes through until you approve it. ## How to connect 17hats to your AI agent 1. **Sign in to 17hats in a Cloud Browser.** Create a Cotlet account, open 17hats in its Cloud Browser, sign in with your 17hats 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. 17hats shares the address `https://cotlet.dev/mcp/v1` with every other app you enable, so one connector covers them all. Turned 17hats on after connecting? Refresh the connector and the 9 tools appear.

A workflow step that emails the client follows your workflow settings. - **List contacts** (`list_contacts`, read): Contacts by type (hot lead, client, cold prospect), searchable by name or email. - **Add contact** (`add_contact`, write): Adds a contact, for example a new lead. - **List projects** (`list_projects`, read): Projects with status, date, amount due and open to-dos. - **Create project** (`create_project`, write): Creates a project for a contact, with a workflow if you use one. - **List to-dos** (`list_todos`, read): Your to-dos due today or overdue, by project. ### Documents and payments Quotes, contracts, invoices and recorded payments wait for your OK. - **Send quote** (`send_quote`, write, asks first): Creates and sends a quote on a project. - **Send contract** (`send_contract`, write, asks first): Sends a contract from your templates for signing. - **Send invoice** (`send_invoice`, write, asks first): Creates and sends an invoice on a project. - **Record payment** (`record_payment`, write, asks first): Records a payment made outside 17hats. Inputs, REST path and example response of every tool: https://cotlet.dev/integrations/17hats-api-mcp-server#tools ## Who can see my 17hats session, and how do I revoke it? - **What we store.** Your signed-in 17hats profile, AES-256-GCM encrypted, in Finland. No password. - **What your agent gets.** The 9 17hats tools, never the session cookie. - **What the session sees.** What your login sees: contacts, projects, documents, to-dos. - **What no tool touches.** Bookkeeping, bank connections, texting, refunds, deletes. - **If 17hats 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 17hats 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 17hats changes? - **12 h** between tests of the 17hats reads - **24 h** between tests of sends a customer would notice - **$0** for a call to a 17hats tool paused for repair When 17hats moves a button on a project or renames a document 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. **Finds the project.** By client and date. 2. **Builds the quote.** From your items. 3. **Fills the contract.** From your template. 4. **Waits, then sends.** Both show up in your Cotlet console first. | Action | Undo | |---|---| | Add a contact or project | Yes, edit or archive it in 17hats | | Send a quote, contract or invoice | No, it is in the client's inbox; void it in 17hats | | Record a payment | Yes, delete the payment in 17hats | 4 of 9 tools ask first: send_quote, send_contract, send_invoice, record_payment. New contacts and projects reach no customer, so they run at once. You can turn the wait off per tool once you trust a routine. MCP call: ``` { "name": "add_contact", "arguments": { "name": "Tyler Brennan", "email": "tyler@example.com", "type": "Hot Lead", "note": "Headshots, early December" } } ``` REST: ``` curl -X POST https://cotlet.dev/api/v1/17hats/contacts \ -H "Authorization: Bearer $COTLET_API_KEY" \ -H "Content-Type: application/json" \ -d '{"name":"Tyler Brennan","email":"tyler@example.com","type":"Hot Lead","note":"Headshots, early December"}' ``` Response: ``` { "contact_id": "CT-77188", "name": "Tyler Brennan", "type": "Hot Lead" } ``` A cron job or n8n flow can call the same tools over REST at `/api/v1/17hats` with the same key and price, in JSON.

ChatGPT and Claude then work in your 17hats account through Cotlet, in their phone apps too. ### What can ChatGPT do in 17hats? With Cotlet, ChatGPT, Claude and other AI agents handle jobs like these in 17hats: log enquiries as leads; quote and book; plan the 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 17hats? No. 17hats has no ChatGPT or Claude connector of its own and 17hats has no official MCP server (checked 9 Nov 2026). Cotlet is an independent one that works in ChatGPT, Claude, Cursor and any MCP client, on your signed-in account. ### Can ChatGPT add leads in 17hats? Yes, with Cotlet. ChatGPT adds enquiries as hot leads and starts the project with your workflow, so nothing gets lost in your inbox. ### Can ChatGPT send invoices in 17hats? Yes, with Cotlet. ChatGPT creates the invoice on the project and sends it with the payment link after your OK. Your automatic reminders then run as usual. ### Can ChatGPT send quotes and contracts in 17hats? Yes, with Cotlet. ChatGPT builds the quote from your items and fills your contract template, and both wait for your OK before they go out. ### Do I need the new 17hats plan to use Cotlet? No. Cotlet works through your own 17hats login on any plan. The Zapier key is limited to the new subscription plan and to contacts. ### Is the MCP server different from the REST API? Only in how it is called. Both carry the same 9 tools, inputs, answers, API key and price. Agents use MCP; scripts and HTTP steps use REST. ### Is Cotlet affiliated with 17hats? No. Cotlet is independent and not affiliated with 17hats. --- 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.
