Pre-engagement reconnaissance workflow using HackerOne MCP tools to enumerate program scope, study prior disclosures, and identify high-value targets. Use when starting a new HackerOne program engagement, building an asset inventory, or planning target selection before active testing.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# HackerOne Pre-Engagement Recon Prerequisite: HackerOne MCP server running with valid credentials (`H1_USERNAME` + `H1_API_TOKEN`). Verify with `hackerone_health`. ## Phase 1: Program Intelligence ### 1.1 Retrieve program details ``` hackerone_get_program(program_handle="<handle>") ``` Extract: program type (bounty vs VDP), submission state, response metrics, bounty splitting, excluded vuln types, severity thresholds. **Checkpoint:** If program is not accepting submissions, stop. If response metrics show >30 day triage, prepare stronger evidence. ### 1.2 Enumerate scope assets ``` hackerone_get_program_scope(program_handle="<handle>") ``` Record for each asset: type, identifier, bounty eligibility, max severity, per-asset instructions. **Prioritize:** (1) bounty-eligible + critical severity cap, (2) wildcard domains, (3) API endpoints, (4) recently added assets. ### 1.3 Map accepted weaknesses ``` hackerone_get_program_weaknesses(program_handle="<handle>") ``` Record CWE categories accepted. You need `weakness_id` values for report submission. ## Phase 2: Prior Art Analysis ### 2.1 Study disclosed reports ``` hackerone_search_hacktivity(program="<handle>") ``` …

How to install
mdr add dreadnode/capabilities/hackerone-recon@sha256:2ba70e908f0e3780The line at the top of this page pins the label git:20260731.af2d5ac, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
