⁠OWASP ZAP MCP Server

MCP server wrapper for Zap⁠ — Automated security scanning proxy (headless).

⁠What is Zap?

Zap (zap.sh) is a security tool that provides: Automated security scanning proxy (headless).

See zaproxy/zap-core⁠ for full documentation.

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

Summary. MCP server wrapper for Zap⁠ — Automated security scanning proxy (headless).

Tools:

• run_zap — Run zap.sh with the given arguments. Returns structured JSON output.

⁠Tools Reference

⁠run_zap

Run zap.sh with the given arguments. Returns structured JSON output.

{
  "raw": "zap.sh 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 zap.sh with --help to see all available options."
• "Use zap to scan the target 192.168.1.1."
• "What options does zap.sh support? Show me its help output."
• "Run zap against example.com with default settings."
• "Execute zap.sh with verbose output enabled."
• "Use the zap 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/zap-mcp:latest

⁠Docker Run (HTTP streamable mode)

docker run -d -p 8231:8231 \
  -e MCP_TRANSPORT=streamable-http \
  -e MCP_PORT=8231 \
  hackerdogs/zap-mcp:latest

⁠MCP Client Configuration

⁠Stdio mode (default)

Add to your Claude Desktop or Cursor MCP config:

{
  "mcpServers": {
    "zap-mcp": {
      "command": "docker",
      "args": ["run", "-i", "--rm", "-e", "MCP_TRANSPORT", "hackerdogs/zap-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": {
    "zap-mcp": {
      "url": "http://localhost:8231/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/zap-mcp:latest .

⁠Testing

⁠Automated tests

./test.sh

⁠Test directly with Docker

1. Start the server in HTTP mode:

docker run -d --rm --name zap-mcp-test -p 8231:8231 \
  -e MCP_TRANSPORT=streamable-http \
  hackerdogs/zap-mcp:latest

2. Initialize the MCP session:

SESSION_ID=$(curl -s -D - -X POST http://localhost:8231/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:8231/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:8231/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_zap","arguments":{"arguments":"--help"}}}'

4. Clean up:

docker stop zap-mcp-test

⁠Running the tool directly (bypassing MCP)

You can run the zap.sh (OWASP ZAP) CLI in the same container by overriding the entrypoint for headless passive or active scanning without starting the MCP server.

Show help:

docker run -i --rm --entrypoint zap.sh hackerdogs/zap-mcp:latest -h
