How to Set Up and Use HackerOne
The HackerOne MCP Server provides AI-assisted access to the HackerOne bug bounty platform through 16 read and write tools. Security researchers can search and filter their submitted reports by program, severity, or state; retrieve triage conversations and report timelines; check program scopes and asset eligibility; and even submit new vulnerability reports or add comments — all through natural language. It is purpose-built for bug bounty hunters who want to analyze their hunting patterns, draft reports consistent with past submissions, and streamline their HackerOne workflow.
Prerequisites
- Node.js 18+ and npm installed
- A HackerOne account with reports or program participation
- HackerOne API credentials: your username and an API token (generated at HackerOne Settings → API Token)
- An MCP-compatible client: Claude Desktop or Claude Code CLI
Clone and build the server
Clone the repository, install dependencies, and compile the TypeScript source.
git clone https://github.com/Sicks3c/hackerone-mcp-server.git
cd hackerone-mcp-server
npm install
npm run buildGenerate a HackerOne API token
Log in to HackerOne, go to Settings → API Token, and create a new token. Copy both your username and the token — you will need them for the next step.
Register the server with Claude Code CLI
Use the claude mcp add command to register the server with your credentials. Replace the path and credentials with your actual values.
claude mcp add hackerone \
-e H1_USERNAME=your-h1-username \
-e H1_API_TOKEN=your-api-token \
-s user \
-- node /path/to/hackerone-mcp-server/dist/index.jsOr configure Claude Desktop directly
Alternatively, add the server to your claude_desktop_config.json with your credentials as environment variables.
{
"mcpServers": {
"hackerone": {
"command": "node",
"args": ["/path/to/hackerone-mcp-server/dist/index.js"],
"env": {
"H1_USERNAME": "your-h1-username",
"H1_API_TOKEN": "your-api-token"
}
}
}
}Verify connectivity
Ask your AI assistant to search your reports or list program scopes. A successful response confirms the server is authenticated and working.

Example prompts for bug bounty research and report management via the HackerOne MCP server.
- "Search my HackerOne reports for SSRF findings and summarize their severity and resolution status."
- "Show me the triage conversation on report #2345678 — what questions did they ask?"
- "Analyze my report patterns — which severity level gets resolved fastest?"
- "What assets are in scope for the Uber bug bounty program?"
- "Search disclosed reports on the shopify program for XSS vulnerabilities."Troubleshooting HackerOne
Authentication error: 401 Unauthorized
Verify that H1_USERNAME matches your HackerOne account username exactly (case-sensitive) and that H1_API_TOKEN is the full token string from Settings → API Token. Tokens have a 90-day expiry — regenerate if expired.
npm run build fails with TypeScript errors
Ensure you are using Node.js 18 or later. Run 'node --version' to check. Delete node_modules and run 'npm install' again before retrying the build.
Report submission is rejected or returns validation errors
The submit_report tool requires a valid program handle and a structured vulnerability description. Ensure the program is currently accepting reports and that you have provided the required fields (title, vulnerability type, severity, and description).
