You will get an MCP server built to connect Claude to your internal API
Rising Talent

Project details
Your team already has an API. Claude can't reach it. This fixes that.
I build an MCP server that exposes your endpoints as tools Claude can call directly - read a record, create a ticket, pull a report - without anyone copying JSON into a chat window. You get the server code, auth handling, a config file for Claude Desktop or Claude Code, and a short doc your developers can maintain.
Python or TypeScript, your choice. I test every tool against your real API before handing it over, so nothing arrives half-wired.
I run my own agent system daily, my Upwork ID is verified, and my first completed contract closed at 5.0.
Starter covers a read-only server on one endpoint group. Standard adds write actions and error handling. Advanced covers multiple services, deployment notes, and a week of fixes after delivery.

AI Automation Engineer – Claude Agents & MCP Server Integration (Freelance/Remote)
I hired Paul to build a custom Claude agent with MCP server integration, and I couldn't be more impressed with the results.
What made them stand out:
Deep technical expertise – they don't just prompt, they build. They understand token costs, model limitations, and when to write code instead of relying on prompts.
Cost-conscious – they audited our prompt chains and cut API costs by over 30% without sacrificing quality. That alone paid for the project.
Clean, documented code – I received architecture diagrams, handover notes, and maintainable code – not a black box.
Proactive communication – they flagged risks early, proposed better alternatives, and always kept me in the loop.
Accountable for outcomes – they delivered exactly what we agreed on, on time, and within budget.
This wasn't just a freelancer hitting milestones – they genuinely cared about the project's long-term success. I've already hired them for a second project and plan to continue the partnership.
If you need a battle-tested AI automation engineer who builds systems that actually work in production – this is your person. Highly recommended.

About Paul
AI Automation Engineer | Claude Agents, MCP Servers & Prompt Audits
Leipzig, Germany - 8:05 am local time
That business is small: a handful of self-published KDP titles and a Gumroad shop for ADHD and autism planners. Behind it runs an agent system I wrote myself. It drafts listings, checks files before they go out, and keeps the catalogue tidy. So a system prompt or an MCP server isn't theory to me. It's the thing I fix on a Tuesday when it breaks.
What I take on:
• Prompt and agent audits. You have something that works four times out of five and nobody knows why the fifth one fails. I find out.
• Claude system prompts and agent skills, written and actually tested against the cases you care about.
• MCP server setup, so your tools talk to the model instead of you copy-pasting.
• Document and contract analysis: extract, compare, flag.
• Spreadsheet and Google Sheets automation.
Straight about where I stand: I'm new on Upwork. One paid contract so far, closed at 5.0 stars. I'd rather tell you that than pad a profile.
I'm in Germany, CET. English or German, either is fine.
Steps for completing your project
After purchasing the project, send requirements so Paul can start the project.
Delivery time starts when Paul receives requirements from you.
Paul works on your project following the steps below.
Revisions may occur after the delivery date.
Review your API and requirements
I review your docs, confirm the endpoints and auth method, and agree the tool scope with you.
Build and test the MCP server
I build the server, wire up auth, and test every tool against your real API or sandbox.
