Allows the optional private purchase flow to create and use CarKeeper's existing £9.99 WooCommerce checkout, including paid-report storage and status retrieval.
Allows the optional private purchase flow to connect through a WordPress REST bridge that reuses the existing WooCommerce checkout and report flow.
Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@carkeeper-mcp Compare these cars for me: AB12 CDE, FG23 HJK, LM45 NOP"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
This project connects ChatGPT to the live CarKeeper report engine.
check_vehicle — runs the real CarKeeper engine for a registration.
analyse_purchase — runs the full CarKeeper buying report with price, advert text and optional images.
compare_vehicles — runs CarKeeper on 2–5 cars and ranks them by the Buyer Score returned by the live report.
start_full_report_checkout — optional/private tool that creates the existing £9.99 CarKeeper WooCommerce checkout.
get_report — optional/private tool that reads status/text for an existing paid report.
The commerce tools are disabled by default because the current public Plugin Directory form says digital-goods commerce is not supported. They can still be enabled in Developer Mode for private testing.

Optional private purchase path: ChatGPT -> MCP server -> WordPress REST bridge -> existing WooCommerce checkout/report flow
Use the supplied carkeeper-report-engine-plugin version of the backend. It keeps /generate-report unchanged for the website and adds:
POST /plugin/generate-report
This route requires:
Authorization: Bearer <CARKEEPER_PLUGIN_TOKEN>
Add CARKEEPER_PLUGIN_TOKEN to the Render service environment.
Copy .env.example to .env and set the SAME CARKEEPER_PLUGIN_TOKEN value.
For public/plugin testing, leave:
CARKEEPER_ENABLE_COMMERCE_TOOLS=false
npm install
npm startThe MCP endpoint is:
http://localhost:8787/mcp
npx @modelcontextprotocol/inspector@latestConnect Inspector to http://localhost:8787/mcp using Streamable HTTP.
Expose port 8787 using an HTTPS tunnel such as ngrok and use:
https://YOUR-TUNNEL/mcp
as the app's MCP URL.
Install carkeeper-chatgpt-api.php as a small WordPress plugin. Add this constant somewhere secure in WordPress configuration:
define('CK_CHATGPT_API_TOKEN', 'a-long-random-secret');Set the same value as CARKEEPER_WP_API_TOKEN on the MCP server and set:
CARKEEPER_ENABLE_COMMERCE_TOOLS=true
for private Developer Mode testing only.
The bridge uses the existing CarKeeper report creation, checkout token restoration, £9.99 WooCommerce product and paid-report storage rather than creating a second payment system.
Never commit .env, OpenAI keys, Check Car Details keys, DVLA keys or shared plugin tokens. Generate long random secrets for both shared tokens.
