I will get a working mcp server that connects claude to your API or data source
Catalin B.
About this gig
I will build an MCP (Model Context Protocol) server that connects Claude or any AI assistant directly to your API or data source.
What MCP means for you: instead of copy-pasting data into Claude, you just ask naturally - "look up this record", "check this status", "summarize today's data" - and Claude fetches the real answer live from your system.
What you get:
Python MCP server with clearly defined tools
Tool descriptions written so Claude knows exactly when and how to use them
Async API client with retry logic and proper error handling
Unit tests with mocked network calls
Setup instructions for Claude Desktop and Claude Code
Real demo showing Claude calling the tools live
I've built an MCP server wrapping the Romanian ANAF public API 3 tools, 19 passing tests, real screenshots of Claude using it live. You can review the code and quality before ordering.
Not sure if MCP fits your use case? Message me first and I'll tell you honestly

FAQ
What is MCP and do I need it?
MCP (Model Context Protocol) is an open standard that lets Claude talk to external systems. If you want Claude to read or write your data live instead of you copy-pasting everything into chat, MCP is the right tool.
Do you need access to my API?
If your API is public I can access it myself. If it's private or requires credentials, share a test API key and I'll work with that. All credentials are deleted after delivery.
Which AI assistants does this work with?
Primarily Claude Desktop and Claude Code, which have native MCP support. Other MCP-compatible clients work too. Let me know what you're using and I'll confirm compatibility before you order.
