~/Library/Application Support/Claude/claude_desktop_config.json · Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "h1-brain": {
      "command": "TODO",
      "args": [
        "See README: https://github.com/PatrikFehrenbach/h1-brain"
      ]
    }
  }
}

Abra Claude Desktop → Settings → Developer → Edit Config. Reinicie após salvar.

~/.cursor/mcp.json · .cursor/mcp.json

{
  "mcpServers": {
    "h1-brain": {
      "command": "TODO",
      "args": [
        "See README: https://github.com/PatrikFehrenbach/h1-brain"
      ]
    }
  }
}

Cursor usa o mesmo esquema mcpServers que o Claude Desktop. Config de projeto vence a global.

VS Code → Cline → MCP Servers → Edit

{
  "mcpServers": {
    "h1-brain": {
      "command": "TODO",
      "args": [
        "See README: https://github.com/PatrikFehrenbach/h1-brain"
      ]
    }
  }
}

Clique no ícone MCP Servers na barra lateral do Cline, depois "Edit Configuration".

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "h1-brain": {
      "command": "TODO",
      "args": [
        "See README: https://github.com/PatrikFehrenbach/h1-brain"
      ]
    }
  }
}

Mesmo formato do Claude Desktop. Reinicie o Windsurf para aplicar.

~/.continue/config.json

{
  "mcpServers": [
    {
      "name": "h1-brain",
      "command": "TODO",
      "args": [
        "See README: https://github.com/PatrikFehrenbach/h1-brain"
      ]
    }
  ]
}

O Continue usa um array de objetos de servidor em vez de um map.

~/.config/zed/settings.json

{
  "context_servers": {
    "h1-brain": {
      "command": {
        "path": "TODO",
        "args": [
          "See README: https://github.com/PatrikFehrenbach/h1-brain"
        ]
      }
    }
  }
}

Adicione em context_servers. Zed recarrega automaticamente ao salvar.

claude mcp add h1-brain -- TODO 'See README: https://github.com/PatrikFehrenbach/h1-brain'

Uma linha só. Verifique com claude mcp list. Remova com claude mcp remove.

Dica: Populate the local databases once, then queries are free and instant. Re-sync periodically.

Segurança

Permissões, segredos, alcance

Escopos mínimos: HackerOne API token with read access

Armazenamento de credenciais: API token in environment variable or Claude Desktop config

Saída de dados: API calls to HackerOne during sync and scope fetching. Local DB queries have no network calls.

⚠ This tool is designed for authorized security research, CTF competitions, and defensive analysis only. Do not use it against systems you don't own or have written authorization to test.
Only target programs that are active on HackerOne and within their defined scope.
Your HackerOne API token grants access to your account data. Keep it secure.

Solução de problemas

Erros comuns e correções

Empty personal database

Run fetch_rewarded_reports first to populate your local database from HackerOne.

Verificar: Check that h1_data.db file exists and has data

HackerOne API authentication failed

Verify your API token is valid and hasn't expired. Generate a new one at hackerone.com/settings/api_token.

Verificar: curl -H 'Authorization: ...' https://api.hackerone.com/v1/me

hack() returns empty briefing

The program handle may be incorrect. Search for the exact handle on HackerOne's directory.

Verificar: search_programs to find the correct handle

Alternativas

h1-brain vs. outros

Alternativa	Quando usar	Troca
hexstrike-ai	You need active security scanning tools rather than HackerOne-specific intelligence	Broader tool coverage but no HackerOne integration or report history
