About this Gig
Launching an AI agent or MCP server? Test it before launch!
AI agents call the wrong tool, pass bad arguments, or fail silently. I catch these problems early with structured AI agent testing, MCP server testing, and automated LLM evaluation.
ABOUT ME
I'm a Agentic AI/LLM automation engineer with 4+ years of experience, including validating AI model outputs in production analytics. I turn vague bugs into clear, repeatable tests.
WHAT I TEST
- Tool calling accuracy and argument validation
- MCP server schemas, error handling, and edge cases
- Task completion, infinite loops, and failed steps
- Prompt injection and unsafe action checks
- Response consistency across repeated runs
WHAT YOU GET
- Test scenarios built around your use case
- ️ Automated eval scripts you can rerun anytime
- GitHub Actions CI that flags regressions (Premium)
- Prioritized bug report with reproduction steps
