I will build a custom mcp server for claude code and ai agents


Level 2
About this gig
Your MCP server works in the demo, then breaks the moment it touches real auth, real data and real load.
That gap is a backend problem, not a prompt problem. Most MCP servers are written as scripts: no auth scoping, no input validation, blocking handlers that hang the model mid-call, tool descriptions the model misreads.
I'm a backend engineer, four years in production Go and Python. Event-driven microservices, gRPC, RabbitMQ, Postgres. I write MCP servers the same way I write services that have to stay up.
What I build:
- MCP servers over your REST/GraphQL API, Postgres, MongoDB or internal service
- Tool and resource design, so the model calls the right thing instead of guessing
- API key or OAuth auth, scoping, rate limiting, input validation
- Local (stdio) or remote (HTTP/SSE) transport
- Docker, CI/CD, structured logging
- Claude Code setup: CLAUDE.md, subagents, hooks, skills
Also: LangGraph agent workflows, RAG with Pinecone, and the backend services around them.
You get the source in your repo, a README, and a walkthrough. You own all of it.
Message me with what you want the AI agent to do. If MCP is the wrong shape for it, I'll tell you before you order.

FAQ
What is an MCP server and do I actually need one?
MCP is a standard way to give an AI client access to your tools and data. You need one if you want Claude or Cursor to read and write in your systems instead of you pasting context by hand. If a simple API call solves your problem, I'll tell you that.
Will this work with Claude Code, Claude Desktop and Cursor?
Yes. The Model Context Protocol is client-agnostic. I test against the client you name and hand over the exact config block for it. If your team uses several, I set up all of them in the same order.
Do I own the code?
Yes. The server ships into your repo under your license, with a README and setup instructions. Source is in every package, never an extra. My own reusable internal libraries stay mine.
Can you connect it to internal systems behind a VPN or firewall?
Yes. I build against your API contract or a staging environment, then hand over deployment instructions for your network. I don't need production credentials to write the server.
Can you host and deploy the MCP server for me?
Yes, from Production MCP up. Docker image, deployment to your cloud, environment config, structured logging. I walk you through the deploy so your team can redeploy without me.
What languages do you build MCP servers in?
Go, Python or TypeScript. I recommend based on what your team already maintains, since the best server is one your engineers can read. Go when throughput and concurrency matter, Python when it sits next to existing ML code.
Can you fix or audit an MCP server someone else built?
Yes. The usual problems are tool descriptions the model misreads, missing input validation, no auth scoping, and blocking handlers that hang the model mid-call. Send the repo and I'll tell you what's wrong before you order.
Do you build AI agents and RAG pipelines too?
Yes. LangGraph agent workflows, vector search with Pinecone, and the backend services around them. MCP is usually one piece of a larger system and I can build the rest of it.
