Search publicly disclosed HackerOne reports (hacktivity). Useful for learning what gets paid, finding prior art, and understanding what a program considers valid.
AI agents call search_disclosed_reports to retrieve information from HackerOne MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only queries and retrieves publicly available historical data from HackerOne's disclosed reports. It performs no modifications, deletions, or external operations—purely informational retrieval. The low severity reflects minimal risk even if misused by an AI agent, as it accesses already-public information intended for research and learning.
From the tool's definition Tool name 'search_disclosed_reports' and description explicitly states it searches 'publicly disclosed' reports for learning and reference purposes.

"tools": {
"search_disclosed_reports": {}
}
