How to Set Up and Use Bug Bounties
The Bug Bounties MCP server gives AI assistants read-only access to a comprehensive database of companies with active bug bounty and responsible disclosure programs, covering websites, GitHub and GitLab repositories, npm and PyPI packages, and mobile apps. It exposes tools for full-text searching programs, fetching enriched program details, and looking up security contact information across multiple asset types without needing an API key. Security researchers and penetration testers use it to quickly find the right disclosure channel before reporting a vulnerability.
Prerequisites
- Node.js 18 or later installed
- npx available on your PATH
- An MCP-compatible client such as Claude Desktop, Cursor, or Cline
- Optional: BUG_BOUNTIES_API_URL environment variable if connecting to a self-hosted instance
Run the server directly with npx
The bug-bounties-mcp package can be launched on demand without a global install. It requires no API key and connects to the public database at bug-bounties.as93.net.
npx -y bug-bounties-mcpAdd to Claude Desktop configuration
Edit your claude_desktop_config.json to register the server. No environment variables are required for the default public database.
{
"mcpServers": {
"bug-bounties": {
"command": "npx",
"args": ["-y", "bug-bounties-mcp"]
}
}
}Restart Claude Desktop
Fully quit and relaunch Claude Desktop to start the bug-bounties MCP server process.
Optionally run as a hosted HTTP server
If you want to expose the server over HTTP for multiple clients, use the --http flag with a port number.
bug-bounties-mcp --http 4488Test by searching for a known program
Ask your AI client to search the bug bounty database for a well-known company like Google or HackerOne to confirm the connection is working.

Example prompts using the bug bounty search and lookup tools exposed by this MCP server.
- "Search the bug bounty database for programs related to 'cloud storage'"
- "Look up the responsible disclosure contact for github.com"
- "Find the bug bounty program for the 'requests' PyPI package"
- "Get the full details of Google's bug bounty program including scope and rewards"
- "Look up security contact information for the Twitter mobile app"Troubleshooting Bug Bounties
npx takes a long time or installs the wrong package
The package name is 'bug-bounties-mcp' (with hyphen, not underscore). For faster starts, install it globally with 'npm install -g bug-bounties-mcp' and change the command in your config to 'bug-bounties-mcp' with an empty args array.
lookup_website returns no results for a known domain
The lookup_website tool is rate-limited to 8 requests per minute per IP and relies on the site having a security.txt, RDAP record, or other discoverable contact. Some smaller domains may not have any security contact information in the database.
Connecting to a self-hosted instance fails
Pass the base URL via the --api-url flag: 'bug-bounties-mcp --api-url https://my-instance.example.com'. Your instance must expose the same /api/* endpoints as the upstream bug-bounties.as93.net deployment.
