I will build custom ai agents and mcp integrations
About this Gig
I build lightweight, production-ready AI agents and custom MCP (Model Context Protocol) servers using native Node.js and Python. I focus on clean integrations, reliable tool execution, structured data handling, and maintainable code without unnecessary framework overhead.
What I can build and integrate:
- Custom MCP servers connecting external tools and APIs to Claude and other LLMs
- AI agents with multi-step tool calling and workflow logic
- Webhook handlers, background workers, and Telegram/Discord bots
- API integrations with authentication, validation, and error handling
- JSON Schema-based tool interfaces and structured outputs
- State persistence and context-efficient API data handling
How we work:
- Scope: We define the required tools, APIs, authentication, inputs, outputs, and workflow.
- Build & Test: I develop the integration with modular code and test the main execution paths and failure cases.
- Handoff: You receive the source code, setup instructions, configuration details, and a clear README.
Please message me with your required tools, APIs, or workflow before placing an order so we can confirm the technical scope and work together.
FAQ
Do you build a custom web UI or frontend application?
No. This gig focuses strictly on robust backend execution: CLI scripts, API integrations, background workers, and MCP servers. Front-end dashboard development (e.g., custom web apps) is not included unless discussed as a separate custom offer.
Are API costs or LLM token usage fees included in the price?
No. You must provide your own API keys for services like OpenAI, Anthropic, or third-party platforms. I build the integration so you retain 100% control over your credentials, token usage, and billing.
What counts as a revision?
A revision covers bug fixes, configuration adjustments, and logic tweaks within the agreed requirements. Adding new tools, switching to unmentioned APIs, or altering the core architecture midway requires an order upgrade.
Why do you use native Node.js and Python instead of LangChain or CrewAI?
Native code and the official MCP SDK provide deterministic execution, lower latency, predictable token costs, and simple debugging without brittle framework abstractions. If your existing production codebase strictly requires a specific framework, message me first.
Why hire a developer instead of using no-code tools like Zapier or n8n?
No-code platforms work for basic tasks, but break down on complex data transforms, custom MCP protocols, and state persistence. I build lightweight, custom-coded pipelines that execute with lower latency, zero subscription bloat, and full control over your logic and credentials.
What information do you need before we start?
Message me before ordering with your main goal, trigger, and the APIs you want connected. I'll ask a few targeted questions in chat to map out the exact data flow, credentials, and technical scope before you place an order.
