About this gig

I maintain an MCP server on npm: @usenami/signer-mcp. Six tools, TypeScript, MIT.

Two of them run without any credentials, so you can install it and watch it talk to a

live backend before you decide anything about me.

That package is not a demo. It drives a production service where signing keys sit inside

an AWS Nitro Enclave, and the code measurement is published on-chain. Building it taught

me the parts of MCP that tutorials skip: auth that survives a restart, errors an agent can

actually act on, and tool descriptions the model reads correctly the first time.

What I build for you:

  • an MCP server exposing your API, database or internal service as tools
  • schemas written so the model picks the right tool instead of guessing
  • auth, rate limits and error handling that behave under a real agent, not a demo script
  • setup that works in Claude Desktop, Cursor, Cline and any other MCP client
  • a README your team can follow without asking me questions

Send me your API docs or a repo link and tell me what the agent should be able to do.

If MCP is the wrong tool for your case, I will say so before you pay.

You describe the process that eats your team's time. I map it, find what's actually worth automating, and build AI agents that do the work. The tools (n8n, Claude, direct APIs) are my problem, not yours: you get working automation and a short video walkthrough so your team owns it. I do this daily: my own company runs on 20+ AI agents I built, doing code review, deployments and monitoring in production.
