About this gig

Want Claude or ChatGPT to work with your own data, without copy-pasting it into the chat? I build custom MCP (Model Context Protocol) servers that give AI assistants safe, structured access to your app, API or database.


What I build:

  • MCP servers for your REST API, SaaS product or internal tool
  • Database access for PostgreSQL, MySQL, MSSQL or MongoDB
  • Read-only mode with guardrails that block write queries
  • Authentication with API keys or OAuth
  • Local or remote servers, deployed to your cloud
  • Clear tool definitions, so the AI picks the right tool with the right inputs


Why me:

I'm a full stack engineer based in Finland, building with TypeScript, Node.js and Python since 2017. I use MCP and Claude in my own daily work, including read-only database access with safety guardrails, so I know where these integrations break and how to keep your data safe.


You get documented source code, setup instructions and a walkthrough for connecting it to Claude Desktop, Claude Code or ChatGPT.


Please message me before ordering so we can confirm the scope.

    He was great and the work was great. I have been so disappointed in fiverr for these types of tasks/workflows. But he came through with flying colors. He actually went above and beyond the scope of what I needed, which surprised me but I was greatly appreciative of. I'd definitely use him again for...
