⁠Commix MCP Server

MCP server wrapper for Commix⁠ — Command injection exploitation.

⁠What is Commix?

Commix (commix) is a security tool that provides: Command injection exploitation.

See commixproject/commix⁠ for full documentation.

No API keys required — Commix runs locally inside the Docker container.

Summary. MCP server wrapper for Commix⁠ — Command injection exploitation.

Tools:

• run_commix — Run commix with the given arguments. Returns structured JSON output.

⁠Tools Reference

⁠run_commix

Run commix with the given arguments. Returns structured JSON output.

{
  "raw": "commix output will appear here"
}

⁠Example Prompts

Here are example prompts you can use with Claude (or any MCP client) when this tool is connected:

• "Run commix with --help to see all available options."
• "Use commix to scan the target 192.168.1.1."
• "What options does commix support? Show me its help output."
• "Run commix against example.com with default settings."
• "Execute commix with verbose output enabled."
• "Use the commix tool to analyze the target and report findings."

⁠Deploy

⁠Docker Compose (recommended)

docker-compose up -d

⁠Docker Run (stdio mode)

docker run -i --rm hackerdogs/commix-mcp:latest

⁠Docker Run (HTTP streamable mode)

docker run -d -p 8225:8225 \
  -e MCP_TRANSPORT=streamable-http \
  -e MCP_PORT=8225 \
  hackerdogs/commix-mcp:latest

⁠MCP Client Configuration

⁠Stdio mode (default)

Add to your Claude Desktop or Cursor MCP config:

{
  "mcpServers": {
    "commix-mcp": {
      "command": "docker",
      "args": ["run", "-i", "--rm", "-e", "MCP_TRANSPORT", "hackerdogs/commix-mcp:latest"],
      "env": {
        "MCP_TRANSPORT": "stdio"
      }
    }
  }
}

⁠HTTP mode (streamable-http)

First, start the server using Docker Compose or docker run with HTTP mode (see Deploy⁠ above), then point your MCP client at the running server:

{
  "mcpServers": {
    "commix-mcp": {
      "url": "http://localhost:8225/mcp"
    }
  }
}

⁠Environment Variables

⁠Installing in Hackerdogs

The fastest way to get started is through Hackerdogs⁠:

1. Log in to your Hackerdogs account.
2. Go to the Tools Catalog.
3. Search for the tool by name (e.g. "nuclei", "naabu", "julius").
4. Expand the tool card and click Install — you're ready to go.

1. Vendor API key required? Add your key in the config environment variable field before clicking Install. Your key will be encrypted at rest.
2. Enable / Disable the tool anytime from the Enabled Tools page.
3. Need to update a key or parameter? Go to My Tools → toggle Show Decrypted Values → edit → Save.

⁠Build

docker build -t hackerdogs/commix-mcp:latest .

⁠Testing

⁠Automated tests

./test.sh

⁠Test directly with Docker

1. Start the server in HTTP mode:

docker run -d --rm --name commix-mcp-test -p 8225:8225 \
  -e MCP_TRANSPORT=streamable-http \
  hackerdogs/commix-mcp:latest

2. Initialize the MCP session:

SESSION_ID=$(curl -s -D - -X POST http://localhost:8225/mcp \
  -H "Content-Type: application/json" \
  -H "Accept: application/json, text/event-stream" \
  -d '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2024-11-05","capabilities":{},"clientInfo":{"name":"test","version":"0.1"}}}' \
  2>&1 | grep -i mcp-session-id | awk '{print $2}' | tr -d '\r\n')

curl -s -X POST http://localhost:8225/mcp \
  -H "Content-Type: application/json" \
  -H "Accept: application/json, text/event-stream" \
  -H "mcp-session-id: $SESSION_ID" \
  -d '{"jsonrpc":"2.0","method":"notifications/initialized"}'

3. Call a tool:

curl -s -X POST http://localhost:8225/mcp \
  -H "Content-Type: application/json" \
  -H "Accept: application/json, text/event-stream" \
  -H "mcp-session-id: $SESSION_ID" \
  -d '{"jsonrpc":"2.0","id":2,"method":"tools/call","params":{"name":"run_commix","arguments":{"arguments":"--help"}}}'

4. Clean up:

docker stop commix-mcp-test

⁠Running the tool directly (bypassing MCP)

You can run the commix CLI in the same container by overriding the entrypoint to test for command injection without starting the MCP server.

Test a URL:

docker run -i --rm --entrypoint commix hackerdogs/commix-mcp:latest -u "https://example.com/page?cmd=test"

Show help:

docker run -i --rm --entrypoint commix hackerdogs/commix-mcp:latest --help
