Cotlet runs 10 Contractor+ tools hosted, over MCP for agents and REST for scripts, in your own Contractor+ login on any plan. Your AI agent writes estimates from your site notes, turns approved ones into scheduled jobs, invoices finished work and lists what is overdue. Sign in to Contractor+ once in your own Cloud Browser. No Pro Team API needed. - Free 7-day trial, no card - Unofficial, not affiliated with Contractor+ - Page: https://cotlet.dev/integrations/contractor-plus-api-mcp-server ## What can your AI agent do in Contractor+? - Write estimates from site visit notes - Send estimates for approval - Turn approved estimates into jobs - Invoice completed jobs - List overdue invoices - Add new clients before quoting ## Does Contractor+ have an MCP server or an API? - Contractor+ has three plans: Freedom (free), Pro and Pro Team. - Zapier and the Developer API both come with Pro Team. - Contractor+ has no connector in the ChatGPT apps directory or in Claude. | What you need | Contractor+ API | By hand | Cotlet | |---|---|---|---| | Estimates and jobs | Pro Team only | Yes, one by one | Yes | | Send an estimate or invoice | Pro Team only | Yes, one by one | Yes, after your OK | | Overdue list | Pro Team only | Yes, a filter | Yes | | Ask in ChatGPT or Claude | No | No | Yes | | Contractor+ plan needed | Pro Team | Any | Any | Checked 8 Nov 2026.

We never keep your Contractor+ password, and no estimate or invoice reaches a client until you approve it. ## How to connect Contractor+ to your AI agent 1. **Sign in to Contractor+ in a Cloud Browser.** Create a Cotlet account, open Contractor+ in its Cloud Browser, sign in with your owner or admin 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. Contractor+ shares the address `https://cotlet.dev/mcp/v1` with every other app you enable, so one connector covers them all. Turned Contractor+ on after connecting? Refresh the connector and the 10 tools appear.

An approved estimate becomes a job with its lines, date and crew. - **List estimates** (`list_estimates`, read): Estimates by status or client. - **Create estimate** (`create_estimate`, write): Creates a draft estimate for a client. - **Send estimate** (`send_estimate`, write, asks first): Emails an estimate to the client for approval. - **List jobs** (`list_jobs`, read): Jobs by status, date or crew member. - **Create job** (`create_job`, write): Creates a job, from an approved estimate or from scratch. ### Invoices An invoice is built from the completed job and stays unsent until you OK the send. - **List invoices** (`list_invoices`, read): Invoices by status, with balances. - **Create invoice** (`create_invoice`, write): Builds an invoice from a completed job. - **Send invoice** (`send_invoice`, write, asks first): Emails an invoice to the client.

No password. - **What your agent gets.** The 10 Contractor+ tools, never the session cookie. - **What the session sees.** What your login sees: clients, estimates, jobs, invoices. - **What no tool touches.** Card charges, payouts, payroll, plan and billing, deletes. - **If Contractor+ 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 Contractor+ 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 Contractor+ changes? - **12 h** between tests of the Contractor+ reads - **24 h** between tests of sends a customer would notice - **$0** for a call to a Contractor+ tool paused for repair When Contractor+ moves the Send button or renames an estimate status, 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 your site notes.** Client, lines, quantities and prices. 2. **Finds or adds the client.** So a repeat customer is not duplicated. 3. **Creates a draft estimate.** And shows you the total. 4. **Waits, then sends.** The send shows up in your Cotlet console first. | Action | Undo | |---|---| | Create an estimate or invoice | Yes, edit or delete the draft | | Create a job | Yes, edit or cancel it in Contractor+ | | Add a client | Yes, edit it | | Send an estimate or invoice | No | 2 of 10 tools ask first: send_estimate, send_invoice. A new client, a draft estimate, a job or a draft invoice reach no customer, so they run at once. You can turn the wait off per tool once you trust a routine. MCP call: ``` { "name": "send_estimate", "arguments": { "estimate_id": "E-1195" } } ``` REST: ``` curl -X POST https://cotlet.dev/api/v1/contractor-plus/estimates/E-1195 \ -H "Authorization: Bearer $COTLET_API_KEY" ``` Response: ``` { "estimate_id": "E-1195", "status": "Sent", "sent_to": [ "sam@example.com" ] } ``` A cron job or n8n flow can call the same tools over REST at `/api/v1/contractor-plus` with the same key and price, in JSON. Failed calls are free. Each tool row above shows its REST path. ## How much does the Contractor+ MCP server cost? **About $19 a month** for a flooring contractor with a crew of 3, 3,260 credits. Your Contractor+ plan stays as it is. | Job | Calls | Credits | |---|---|---| | Estimate from site notes, sent | 4 × 25 | 1,000 | | Approved estimate to job | 2 × 12 | 240 | | Finished job invoiced and sent | 4 × 12 | 480 | | Overdue list, weekly | 1 × 4 | 40 | | Cloud Browser, 30 days | | 1,500 | | Total | | 3,260 | - Free 7-day trial, no card - 10 credits per successful call, MCP or REST - 50 credits a day for the Cloud Browser - Works on Freedom, Pro and Pro Team Contractor+ publishes no job counts, so the month is our example. Dollars at the $29 pack rate. ## Contractor+ MCP server on GitHub, Zapier or hosted: which to use | Option | What it does | Where it stops | |---|---|---| | Contractor+ Developer API | Clients, estimates, jobs and invoices for your own developer. | Pro Team plan; you build and host the code. | | Zapier (Pro Team) | Fixed workflows between Contractor+ and other apps. | Pro Team plan and a Zapier plan; the workflow does what you built, not what you ask. | | By hand | Every screen of Contractor+, one record at a time. | Your evenings. | If you are on Pro Team and have a developer, the API is cheaper for simple reads.

Sign up free at https://cotlet.dev, open Contractor+ under Integrations in the console and sign in to Contractor+ in its Cloud Browser. The trial starts with your first app and asks for no card. ### How do I connect Contractor+ to ChatGPT or Claude? Sign up at cotlet.dev, log in to Contractor+ 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 Contractor+ account through Cotlet, in their phone apps too. ### What can ChatGPT do in Contractor+? With Cotlet, ChatGPT, Claude and other AI agents handle jobs like these in Contractor+: write estimates from site visit notes; turn approved estimates into jobs; invoice completed jobs. 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 Contractor+? No. Contractor+ has no ChatGPT or Claude connector of its own and Contractor+ 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 Contractor+? Yes, with Cotlet. Tell ChatGPT the client and the lines and it creates the estimate as a draft, then sends it for approval after your OK. ### Can ChatGPT send invoices in Contractor+? Yes, with Cotlet. ChatGPT builds the invoice from the completed job and emails it to the client after your OK. ### Can ChatGPT create jobs in Contractor+? Yes, with Cotlet. ChatGPT turns approved estimates into jobs with a date and crew, so nothing waits for the office. ### Do I need the Pro Team plan to use Contractor+ with Cotlet? No. Cotlet works through your own Contractor+ sign-in, so it needs no API key, which Contractor+ includes only with Pro Team. It can do what your plan and login can do. ### Can it charge a client's card? No. Payments stay in Contractor+. The agent creates and sends invoices, and lists what is still unpaid. ### Is the MCP server different from the REST API? Only in how it is called. Both carry the same 10 tools, inputs, answers, API key and price. Agents use MCP; scripts and HTTP steps use REST. ### Is Cotlet affiliated with Contractor+? No. Cotlet is independent and not affiliated with Contractor+. --- 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.
