You will get a custom MCP server that connects your API, database or tools to AI
Project details
Give your AI assistant safe, direct access to your own tools and data. An MCP (Model Context Protocol) server is the standard way to let Claude, Cursor, or any MCP-compatible AI actually DO things in your stack — query your database, call your API, search your docs, create records. I build it from scratch, around your specific tools.
What you get:
• A working MCP server wired to your API, database, or SaaS tool
• Tools the AI can call reliably, with input validation and clear errors
• Secure key handling — nothing hardcoded, nothing leaked
• A GitHub repo you fully own, plus a README and a Loom of it running live
For devs who want their internal API or DB usable from Claude or Cursor, AI agents that need governed access to live data, and SaaS builders shipping an MCP integration.
How I work: fully async. Send your API docs, database details, or a sample of the tool; I build, test against real calls, and deliver a repo plus a walkthrough. Every tool tested before handoff.
US-based, code-first AI engineer with production MCP servers in my portfolio. New to Upwork, so entry pricing is low for first reviews. Message me what you want connected and I'll tell you how I'd build it.

About Tony
AI Agent & MCP Engineer | RAG, LLM Integration, Full-Stack AI Apps
Alpharetta, United States - 12:16 am local time
I'm a US-based, code-first AI engineer (Nexus Digital Group). Real systems I've shipped:
- A 26-agent autonomous marketing department on the Claude Agent SDK (Next.js, compliance hooks) running across 7 coordinated departments
- A conversational pricing assistant wired to a LIVE MCP server, with an agentic workflow and guardrails
- A citation-backed RAG chatbot that grounds every answer in your docs and never fabricates (Vercel AI SDK + Claude)
- A PDF-to-JSON extraction API — stateless, schema-validated, Claude-backed
- A multi-tenant AI SaaS app (Next.js/Supabase/Stripe) and a digital origination platform with 15+ third-party API integrations
What I deliver:
- AI agents & MCP servers — multi-agent orchestration, tool use, guardrails, the Claude Agent SDK
- RAG chatbots — citation-backed, grounded in your docs, built so they don't hallucinate
- Full-stack AI apps — Next.js / TypeScript / React, Supabase, Stripe, plus React Native mobile
- Custom LLM & API integrations — OpenAI/Claude wired into your stack, your data, your auth
- Document & data extraction — PDF/Excel to clean, schema-validated JSON
How I work:
- Fixed price, scoped clearly up front — you know the cost before I start
- Same-week turnaround on most well-defined builds
- Every delivery includes a Loom walkthrough and a setup doc so you can run it yourself
- Tested against your real data before handoff — not a happy-path demo
Stack: Next.js, TypeScript, React, Node, Python, OpenAI/Claude APIs, LangChain, vector DBs, Playwright, Supabase, Stripe, React Native.
No Upwork reviews yet — I'm building my track record, so you get senior-level engineering at $35/hr and someone motivated to over-deliver. Send me what you're trying to build and I'll reply with exactly how I'd build it, a fixed price, and a realistic timeline.
Steps for completing your project
After purchasing the project, send requirements so Tony can start the project.
Delivery time starts when Tony receives requirements from you.
Tony works on your project following the steps below.
Revisions may occur after the delivery date.
Map tools & confirm scope
I turn your API/DB/tool and the actions you want into a concrete tool list and confirm exactly what fits your tier.
Build the MCP server
I build it in Python (FastMCP) or TypeScript with input validation, auth, and clear errors back to the model.
