Published to the Smithery registry, where it drew about 600 tool calls a month while it was live. 73 GitHub stars, 8 forks (2026-10). I kept extending it alone after the Whitehat School final presentation.

Security MCP server

The LLM picks and calls the right tool for the situation instead of following a fixed script. With trivy SBOM analysis and Perplexity PoC search tools added, it captured flags on 5 of 10 Dreamhack web CTF problems. It was the Whitehat School cohort 3 final project, and I extended it into CTF-Solver after the presentation.
