About this gig

Want Claude, ChatGPT or Cursor to use your product directly? I will build an MCP (Model Context Protocol) server that exposes your API as clean, safe tools.


I built and published one for my own product, Fattly.app: an npm package (npx fattly mcp) plus a hosted MCP server with OAuth, listed on Smithery. Users connect in a minute and generate images, video and audio from chat.


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

- Auth with API key or OAuth, depending on the package

- Tested in Claude Desktop and Cursor before delivery

- Source code, README and a short handover


What I need from you: API docs (OpenAPI is ideal) and a test account.


Not a fit: tools that move money without a human approving it.


Not sure which package fits? Message me before ordering and describe your API in 2-3 sentences.
