I will build a custom mcp server for claude or chatgpt apis and databases


About this gig
Want Claude, ChatGPT, or another MCP-compatible AI assistant to work securely with your real business systems?
I will build a custom MCP (Model Context Protocol) server that connects your AI assistant to APIs, databases, SaaS platforms, or internal tools through controlled MCP actions.
Your AI can:
- Search and retrieve business data
- Query databases safely
- Call REST APIs
- Create or update records
- Connect with CRM and SaaS platforms
- Trigger business workflows
- Access internal applications through controlled tools
I focus on:
- Clean MCP tool design
- Authentication and permissions
- Input validation
- Error handling
- Secure read/write operations
- Maintainable Python code
- Testing and documentation
Typical architecture:
Claude / ChatGPT -> MCP Server -> API / Database / SaaS / Internal System
Depending on your package, you can receive source code, setup instructions, testing, documentation, Docker configuration, and deployment assistance.
Before ordering, please contact me if your project involves multiple systems, OAuth, complex write operations, enterprise permissions, or production deployment.

FAQ
1. What is an MCP server?
An MCP server connects an AI assistant such as Claude or ChatGPT to external tools, APIs, databases, or business systems through controlled actions.
2. Can you connect Claude or ChatGPT to my REST API?
Yes. I can expose selected API operations as MCP tools so the AI can safely read or perform approved actions.
3. Can you connect the MCP server to my database?
Yes. I can connect to supported databases such as PostgreSQL or MySQL using controlled tools instead of unrestricted database access.
4. Can the AI create or update data?
Yes. Read and write actions can be implemented with validation, permissions, and appropriate security controls.
5. Can you build a remote hosted MCP server?
Yes. Remote deployment can be included depending on the selected package and hosting environment. Third-party hosting costs are not included.
6. Do I receive the source code?
Yes. Source code and setup documentation are included according to the package you purchase.
7. What do you need from me to start?
Please provide the API documentation or database schema, the system you want to connect, your target MCP client, and 2–3 examples of what you want Claude or ChatGPT to do. If authentication or deployment is required, please also describe the method and target environment. Do not send production pass
