I will build custom mcp servers for claude code, cursor, and korean apps like naver


About this gig
I build custom MCP (Model Context Protocol) servers so Claude can use your tools, data and websites directly.
I run my own content business on MCP servers I built: YouTube trend research, product video sourcing, e-commerce product search with rate limiting and caching, and keyword volume lookups - plus browser automation for uploading to YouTube, Instagram and TikTok. Korean services are part of that setup too: Coupang product search, Naver keyword volume and Naver blog drafting, so I can also connect Claude to Korean platforms.
What I can build:
- MCP server in Python (FastMCP) or TypeScript
- - Tools that call your APIs, databases or internal scripts
- - Browser automation tools (Playwright) for sites without an API
- - Safe defaults: rate limits, caching, clear error messages, no secrets in code
- - Setup guide for Claude Desktop / Claude Code
You get clean source code, a README, and a short demo of Claude using your new tools.
I will not build tools that bypass captchas, scrape behind logins against a site's terms, or automate spam.

FAQ
Which clients does it work with?
Claude Desktop and Claude Code, plus any client that supports MCP.
Do I need to share my API keys?
No. Keys go in environment variables on your side; I never hard-code them.
