h1-brain An MCP server that connects your AI assistant to HackerOne. It pulls your bug bounty history, program scopes, and report details into a local SQLite database, then exposes tools that let any MCP-compatible client (Claude Desktop, Claude Code, etc.) search, analyze, and build on your past work. It also ships with a pre-built database of 3,600+ publicly disclosed bounty-awarded reports from the HackerOne community — full vulnerability write-ups, weakness types, and bounty amounts. The AI uses both your personal data and public knowledge to generate attack briefings. The primary tool, , generates a full hacking session briefing in a single call: fresh scope from the API, your past findings, public disclosures for that program, weakness patterns, untouched assets, and suggested attack vectors — all formatted as actionable instructions that put the AI in offensive mode.
