I will build a custom mcp server for claude and chatgpt integration


About this gig
I build secure MCP (Model Context Protocol) servers and local tools that let AI agents such as Claude and Cursor access your data, APIs, and development environment safely.
Most MCP integrations grant broad access and rely on prompts to keep an agent in bounds. I build the control layer that makes access limited, auditable, and ready for real-world use.
What you get:
- Custom MCP tools for your database, API, or internal system
- Strict access control with action and table allow-lists, so agents can only do what you explicitly permit
- Structural SQL and query validation before execution
- Row limits, timeouts, and rate limits to prevent unsafe or expensive requests
- Secure integration with your chosen AI client, including Claude and Cursor
- Premium package: request capture and replay tooling to inspect exactly what an agent asked, changed, and executed
- Full source code and documentationyou own the system and can run it yourself
This service is for teams building with AI coding agents that need secure, controlled access to real data and toolsnot a hardcoded demo or unrestricted system access.
Please message me before ordering with your data source, target AI client.

FAQ
What is an MCP server, exactly?
It's a small backend that exposes specific, safe actions (like "list tables" or "run this validated query") to an AI agent such as Claude Desktop or Cursor — instead of giving the agent raw database or system access.
Do you provide support and maintenance after the MCP integration is delivered? A:
Yes. I provide post-delivery support to help with setup, testing, and minor integration issues. Ongoing maintenance, feature updates, new tools, or changes to your API/database can be arranged as a separate support
