I build MCP servers: the layer that lets AI agents (Claude, ChatGPT, Cursor and others) use your product, API or internal data — safely and reliably.
I’m the creator and solo maintainer of OpenOSINT, an MCP-native open-source framework with 1.8k stars on GitHub. Every package below follows the same process I use there: tools designed for agents (not just wrapped APIs), measured with tests, and checked for prompt injection.
Packages
I take one build at a time. Next available start: November 2026.
MCP Audit — $490
For teams that already have an MCP server.
- Review of tool names, descriptions and schemas against agent-design best practices
- Compatibility check against the current MCP specification (2026-07-28)
- Security pass: prompt injection through tool results, tool poisoning, over-broad permissions
- Written report with prioritized, concrete fixes
Delivery: 5 business days after you share access.
Starter MCP Server — $1,900
Your existing API or database, usable by AI agents.
- Up to 5 tools, designed for how agents actually use them
- Local (stdio) or remote (Streamable HTTP) transport
- API key / environment-based authentication
- Tests, README and setup guide for Claude, ChatGPT and Cursor
Delivery: about 2 weeks after the written scope is agreed.
Production MCP Server — $4,900
For products where agents need to reach real users’ data.
- Up to 15 tools
- Remote server with OAuth 2.1, following the 2026-07-28 specification
- Eval suite measuring tool choice and answer accuracy
- Security testing (prompt injection, tool poisoning) with a written report
- Deployment on your infrastructure
Delivery: about 4–5 weeks after the written scope is agreed.

How it works
- Buy. The audit is paid in full; builds start with a 50% deposit.
- Written scope within 48 hours. I email you a short questionnaire, and we agree in writing on tools, data, access and deliverables. If it’s not a good fit, the deposit is refunded in full.
- Build. Weekly progress updates; you see the server working before delivery.
- Delivery. You get a short video of the working server, the code and documentation, then a Stripe invoice for the remaining 50%, due within 7 days. The code and repository are transferred once it’s paid.
You own all the code I write for you.
