I will build a custom mcp server for your app or database, claude and chatgpt


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.

FAQ
What is an MCP server?
It's a small service that lets AI assistants such as Claude or ChatGPT use your tools and data directly. The AI can look up records, call your API or run approved actions, instead of you copying data into the chat.
Is my data safe?
Yes. I give the AI only the access it needs. For databases, I can make the server read-only, block write queries and limit it to specific tables. Your credentials stay on your side and never appear in the code.
Which AI apps will it work with?
Claude Desktop, Claude Code, ChatGPT and any other client that supports MCP.
Which languages and databases do you use?
TypeScript/Node.js or Python, whichever fits your stack best. Databases: PostgreSQL, MySQL, MSSQL and MongoDB.
Do I own the code?
Yes. You get the full source code with documentation, and you can host and change it however you like.
What counts as a "tool"?
A tool is one action the AI can take, such as "search customers", "get order status" or "create invoice". We'll agree on the list before I start.

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...
