I will build a custom mcp server for claude chatgpt or cursor
Nipun T
About this gig
Connect Claude, ChatGPT, Cursor, or another MCP-compatible client to the tools and data your team already uses.
I build custom Model Context Protocol servers with clear tool schemas, secure authentication, error handling, tests, and documentation.
Common integrations include:
REST or GraphQL APIs
PostgreSQL, MySQL, SQLite, or MongoDB
Internal business tools and private services
File, document, or knowledge workflows
Custom actions for AI agents
Every package includes source code, setup instructions, and a working demonstration. Standard can include up to three tools or resources, authentication, client setup, and Docker. Premium is for a larger production server with logging, deployment support, and full documentation.
I can implement the server in Python or Go and connect it to Claude Desktop, Cursor, ChatGPT, or a compatible custom agent.
Before ordering, send the target client, required tools, API or database documentation, authentication method, and preferred deployment environment. I will confirm compatibility and scope before we begin.

I'm a software engineer focused on reliable backend systems, AI integrations, and production-ready web and mobile apps. I build Go and Python APIs, custom MCP servers, AI agents, and Flutter integrations with PostgreSQL, OpenAI, Claude, and Gemini. I am most useful when a project needs clear architecture, secure API design, testing, deployment, and practical documentation. I can also rescue AI-generated apps by fixing bugs, connecting databases and APIs, and preparing them for production. Share your goal, stack, and main blocker. I'll reply with a realistic scope and the best next step.
FAQ
I'm not technical — will you explain what you're building?
Absolutely. I write plain-English documentation for every delivery and offer a walkthrough call. You don't need to understand the code to use the result.
What LLM clients does your MCP server work with?
Primarily Claude (Desktop + API), but MCP servers are open standard and can work with any MCP-compatible agent framework including LangGraph and custom implementations.
Can you connect my MCP server to my existing database?
Yes — PostgreSQL, MySQL, SQLite, and MongoDB are all supported. Add the PostgreSQL integration extra for schema design included.
How is this different from just calling an API directly?
MCP gives your AI agent a structured, type-safe interface with discovery capabilities. The agent knows what tools exist, what they accept, and what they return — making it far more reliable than ad-hoc API calls.
Do you offer ongoing maintenance?
Not as part of gig packages, but I'm open to custom retainer arrangements. Message me to discuss.
