I will build a custom mcp server for claude, cursor or chatgpt
Jan Seyhan
About this gig
- Give your AI assistant real access to your tools. I build Model Context Protocol (MCP) servers that let Claude, Cursor, ChatGPT and other MCP clients read and act on your API, database or SaaS, safely.
What you get:
- A clean, typed MCP server (TypeScript or Python)
- Tools, resources and prompts designed around your real workflows
- Secure auth (API keys or OAuth) and clear error messages
- Setup for Claude Desktop, Claude Code, Cursor and other clients
- Source code and documentation you own
Typical projects:
- Connect your CRM, helpdesk or internal API to Claude
- Let an AI agent query your Postgres or Supabase database with scoped access
- Wrap your SaaS API so your customers can use it from their AI assistant
- Remote MCP servers deployed to the cloud for a whole team
Why me: my studio ships SaaS products and AI features in production, including an AI assistant that answers from a business's own data. Security and logging are defaults, not extras.
Message me before ordering with your API docs and I'll confirm the scope and the right package.

FAQ
Which AI apps can use the MCP server?
Any MCP-compatible client: Claude Desktop, Claude Code, Cursor, VS Code, ChatGPT where custom connectors are available, and your own agents.
TypeScript or Python?
Either. I default to TypeScript with the official SDK, or Python if it fits your stack better.
Can it run remotely for my whole team?
Yes. The Production package includes a remote HTTP server deployed to your cloud with OAuth sign-in.
Is my data safe?
Credentials stay in your environment, every tool gets the minimum access it needs, and tools can be read-only if you prefer.
What do you need from me?
API docs or a database schema, sandbox credentials, and a list of what you want the AI to be able to do.
