Common questions
Is Price Drop Back safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed –, and the latest version (1.4.0) reached the registry 39 days ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
What can I use instead?
In the same category: Spec Driven Development, Remote Desktop Commander, Rystic

How it works
build.pyreads each product's liveopenapi.jsonand writesproducts.js: one tool per GET operation, named from itsoperationId, with inputs from its parameters. Descriptions are tidied into plain tool descriptions.worker.mjsis the MCP server:initialize,tools/listandtools/call, which calls the product's own API and returns its answer. Answers with asayfield carry a ready-made summary.servers.jsonlists every server for the official MCP Registry (asio.github.GoodTurnStudio/). The Publish to the MCP Registry workflow logs in with GitHub OIDC and runspublish.py;publish.ps1does the same from Windows.
Build and test
npm install npm run build # python3 build.py, then bundle to deploy/_worker.js npm test # every product through the worker, against the live APIs npm run test:live # every tool through the deployed servers with the MCP SDK client
Deploy deploy/ as a Cloudflare Pages project in advanced mode (_worker.js).
