I will build a custom mcp server for your API
Chigozzdev
About this gig
Need a custom MCP server to connect your AI assistant to an existing API?
I build MCP tools that let an assistant retrieve information and perform defined actions in your business systems. I work with ChatGPT, Claude, Cursor and compatible agents using Grok, DeepSeek, GLM or other models. We confirm client, transport and authentication support before the order.
You receive:
- Typed tools with validated inputs and structured responses
- API authentication, error handling and relevant tests
- Source code, setup notes and a working demonstration
My work on Uumi includes MCP tools, access checks and approval controls for agent actions.
Basic: 1 API and up to 2 tools, running locally.
Standard: 1 API and up to 5 tools, with one hosted deployment.
Premium: up to 2 APIs and 8 tools, with an agreed write-action approval check.
Each package covers one agreed MCP client. Hosting and API usage fees are separate. New backends, custom OAuth systems and custom agent adapters need a separate scope.
Send your use case, API documentation and target client before ordering.

I'm a backend and integration engineer building AI tools, WhatsApp workflows and web applications. I develop custom MCP servers, connect business APIs, and repair broken application flows. My work includes native WhatsApp catalog and cart integration, payment and order workflows, wallets and developer SDKs. I work with TypeScript, JavaScript, Python, Rust and Go. I define the result before building, test the agreed flow, and provide clear source code and handover notes. Send me your current setup and the outcome you need.

FAQ
Which AI apps and models can you work with?
ChatGPT, Claude, Cursor, or agents using Grok, DeepSeek, GLM and other models, subject to the target client and API support. Each package covers one agreed MCP client. A custom agent adapter may need a separate quote.
What counts as one tool?
One named action for one agreed API operation, such as looking up an order. A complete agent, new API or dashboard is separate scope.
What do you need from me?
Your desired actions, target client and existing API documentation. We arrange limited project access in the order chat. Custom OAuth or missing API endpoints need a separate quote.
Are hosting and API charges included?
No. You own the accounts and pay their usage costs. Standard and Premium include one agreed deployment; ongoing maintenance is separate.
