   • Run an nmap scan on specified targets
   • Parameters:
     • target: Target host or network (e.g., 192.168.1.1 or 192.168.1.0/24)
     • options: Nmap options (e.g., -sV -p 1-1000)
2. get-scan-details
   • Get detailed information about a specific scan
   • Parameters:
     • scan_id: ID of the scan to retrieve
3. list-all-scans
   • List all available scan results
   • No parameters required

Available Prompts

1. analyze-scan
   • Analyze an nmap scan result
   • Parameters:
     • scan_id: ID of the scan to analyze
     • focus: Focus area (security/services/overview)

Resources

Scan results are available as resources with the nmap://scan/{scan_id} URI scheme.

Example Workflow

1. Run a scan:
   Call tool: run-nmap-scan Parameters: {"target": "192.168.1.0/24", "options": "-sV -p 22,80,443"}
2. Get scan details:
   Call tool: get-scan-details Parameters: {"scan_id": "<scan_id from previous step>"}
3. List all scans:
   Call tool: list-all-scans
4. Analyze scan results:
   Get prompt: analyze-scan Parameters: {"scan_id": "<scan_id>", "focus": "security"}

Security Considerations

This server executes nmap commands on your system. Be cautious when scanning networks you don't own or have permission to scan, as unauthorized scanning may be illegal in some jurisdictions.

Troubleshooting

If you encounter errors related to nmap not being found or being executed incorrectly:

1. Make sure nmap is installed and available in your PATH
2. Check the logs for which nmap executable is being used
3. The server will attempt to use the full path to nmap to avoid conflicts

Docker Usage

You can run the MCP server in a Docker container:

For integration with the Glama MCP directory, the Docker container allows others to easily use this MCP server without worrying about installation dependencies.
