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.
