}Remote MCP servers for 25 free, read-only everyday helpers by Good Turn Studio: money, health, jobs, travel, shopping, halal checks, football and scripture reading. One Cloudflare Worker turns each product's public OpenAPI spec into an MCP server, so any assistant that speaks MCP (Claude, ChatGPT, Alexa+, Cursor, VS Code and others) can use them.
https://goodturn-mcp.pages.dev/<slug>/mcphttps://goodturn-mcp.pages.dev/all/mcp (tool names start with the product slug)readOnlyHint: true, destructiveHint: false, idempotentHint: true)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.Deploy deploy/ as a Cloudflare Pages project in advanced mode (_worker.js).
MIT for this code. Each product's API, data and answers belong to that product and are served under its own terms, linked from its page at https://goodturn-mcp.pages.dev/<slug>.
