Custom MCP server for Claude, ChatGPT and CursorRafal Czarnecki
I will build an MCP server so Claude, ChatGPT and Cursor can use your product's API. I built and published one for my own SaaS, Fattly.app: an npm package (npx fattly mcp) plus a hosted server with OAuth, listed on Smithery.
What you get
Clear tool names and descriptions, so the model picks the right tool
Safe defaults: anything that writes data or costs money asks for confirmation
A test run in Claude Desktop and Cursor before delivery
README and a short setup guide
Packages
Basic, 300 USD, 5 days: up to 3 tools, read only, runs locally (stdio), README
Standard, 750 USD, 10 days: up to 8 tools including write actions with confirmation, hosted HTTP server with OAuth or API key, docs
Premium, 1,400 USD, 14 days: Standard plus an npm package, directory listings (Smithery and similar), per key spending limits and logs
The price shown is the Basic package. What I need from you: API docs and a test account. Message me here or on Telegram (@rafallAI) with your API and I will confirm the scope before we start.
