You will get a custom MCP server that connects your tools to Claude and AI agents
Project details
Want Claude, Cursor, or your agent stack to actually use your internal tools, APIs, or database? I build custom MCP (Model Context Protocol) servers that expose your systems to AI agents — cleanly, with structured tool definitions and proper error handling.
I work with agent tooling every day. My open-source project HaltTrace traces MCP and tool-exception events, so I build servers that don't silently fail under real agent traffic. You get the full source code, tests, and setup docs — not a black box, and no lock-in.
Built in TypeScript/Node.js or Python to match your stack, and tested against the actual client you use. Bilingual KR/EN with fast, specific communication.

Frequently asked questions
About Lee
Production AI Engineer : LLM Agents, MCP Servers & Realtime Voice AI |
Busan, South Korea - 10:24 am local time
* Knows Python, FastAPI, TypeScript, Node.js, and C++ — plus LLM agents, RAG, MCP servers, and realtime voice AI (OpenAI Realtime)
* I direct AI to build fast, then verify everything with tests and benchmarks before it ships — no untested "vibe-coded" code
* Full project management from start to finish, with runnable proof you can check yourself
* Regular communication is important to me, so let's keep in touch.
Steps for completing your project
After purchasing the project, send requirements so Lee can start the project.
Delivery time starts when Lee receives requirements from you.
Lee works on your project following the steps below.
Revisions may occur after the delivery date.
Requirements & tool design
I confirm which tools, APIs, and data sources to expose, then design clean tool definitions and the error-handling approach before writing code.
MCP server development
I build the MCP server in TypeScript/Node.js or Python, implementing each tool with input validation, structured responses, and proper error handling.
