How it works

build.py reads each product's live openapi.json and writes products.js: one tool per GET operation, named from its operationId, with inputs from its parameters. Descriptions are tidied into plain tool descriptions.
worker.mjs is the MCP server: initialize, tools/list and tools/call, which calls the product's own API and returns its answer. Answers with a say field carry a ready-made summary.
servers.json lists every server for the official MCP Registry (as io.github.GoodTurnStudio/<slug>). The Publish to the MCP Registry workflow logs in with GitHub OIDC and runs publish.py; publish.ps1 does the same from Windows.

Build and test

code

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).
