I will build a custom mcp server for claude, chatgpt and cursor


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.

FAQ
Which AI apps will my MCP server work with?
Claude Desktop, Claude Code and Cursor out of the box. Hosted servers with OAuth also work as custom connectors in Claude and in other MCP clients. I test in Claude Desktop and Cursor before delivery.
