Custom MCP server connecting Claude or ChatGPT to your API or database

I build custom MCP servers that connect Claude, ChatGPT, Cursor or Claude Code to your API or database.

Your team asks their AI about your real data and gets real answers, not guesses, with the right access so nobody sees what they shouldn't.

What you get

You get the code in your repo, tests, and it set up in your team's AI tools.

Good for an MCP server for your REST API, a Claude MCP integration for your Postgres or MySQL database, or giving your internal tools to your team's AI agents.

How it works

  1. Pick what your AI should do

    We list 3 to 5 things your team wants to ask or do, and I go through your API docs or database schema.

  2. Build the MCP tools

    I build each tool with the right access rules, so the AI only sees what it should.

  3. Test with real questions

    I write tests and run your real questions in Claude or ChatGPT until the answers are right.

  4. Setup and handover

    I set it up in your team's AI apps, push the code to your repo and walk you through it.

Why me

I've been a developer for almost 10 years. I built an MCP server for a multi-client ad platform with OAuth, per-client access, Redis and Docker. I also built a Claude plugin there that took ad debugging from a full day with several engineers down to about two minutes for one person.

FAQ

What is an MCP server?

It's a small server that gives your AI app safe tools to read or update your own systems.

Is my data safe?

It runs on your servers with the least access needed, and the keys stay with you.

Does it work with ChatGPT too?

Yes, any app that supports remote MCP servers can connect.

Can it write data, not just read?

Yes from Standard up, with a confirm step on anything risky.

How do we communicate?

After you pay, I invite you to my Slack. We talk there, so every message, file and decision stays in one place. Calls when we need them.
