HackerOne

An MCP server that connects Claude to the HackerOne Hacker API. List your programs, pull structured scope, read and submit reports, browse Hacktivity, and check your balance — all from inside Claude Code.

Tools

Setup

1. Get an API token

Go to https://hackerone.com/settings/api_token/edit, create a token, and note both the identifier (username) and the token value.

2. Install deps

cd ~/projects/hackerone-mcp
uv venv .venv
uv pip install --python .venv/bin/python -r requirements.txt

3. Add credentials

cp .env.example .env
# edit .env and fill in HACKERONE_API_USERNAME + HACKERONE_API_TOKEN

The server auto-loads .env from this folder — nothing else to configure.

4. Test

.venv/bin/python -c "import hackerone_mcp as h; print(h.test_connection())"

5. Register with Claude Code

claude mcp add hackerone -- ~/projects/hackerone-mcp/.venv/bin/python ~/projects/hackerone-mcp/hackerone_mcp.py

Then in Claude: "list my HackerOne programs" or "pull the scope for program X".

To register only for the current project instead, add --scope project.

Manual config (any MCP client)

{
  "mcpServers": {
    "hackerone": {
      "command": "/home/kali/projects/hackerone-mcp/.venv/bin/python",
      "args": ["/home/kali/projects/hackerone-mcp/hackerone_mcp.py"]
    }
  }
}

Credentials come from .env, or set HACKERONE_API_USERNAME / HACKERONE_API_TOKEN in the env block of the config.

Notes

• Base URL: https://api.hackerone.com/v1, HTTP Basic auth.
• submit_report creates a real report — review details before calling.
• .env is gitignored; never commit your token.
