goodturn-mcp
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.
- One server per product: https://goodturn-mcp.pages.dev//mcp
- All products in one: https://goodturn-mcp.pages.dev/all/mcp (tool names start with the product slug)
- Streamable HTTP, stateless JSON, MCP 2025-11-25 (and 2025-06-18, 2025-03-26), no sign-in
- Every tool is read-only, with a title and annotations (readOnlyHint: true, destructiveHint: false, idempotentHint: true)
- Nothing about the user is stored. Privacy: https://goodturn-mcp.pages.dev/privacy
Products
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/). The Publish to the MCP Registry workflow logs in with GitHub OIDC and runs publish.py; publish.ps1 does the same from Windows.
