nmap Scan Management

How to Call the nmap MCP Tools

python3 $MCP_CALL "python3 -u $NMAP_MCP_SCRIPT" TOOL_NAME '{"param":"value"}'

When to Use

• Run nmap with flags not covered by the purpose-built tools
• Review past scan results without re-scanning
• Compare before/after scans (pre-change vs post-change)
• Retrieve a specific scan result by ID

Available Tools

Tool	Purpose
nmap_custom_scan	Run nmap with arbitrary flags (scope-enforced + audit-logged)
nmap_list_scans	List recent saved scans with IDs, timestamps, targets
nmap_get_scan	Retrieve full results of a previous scan by ID

Custom Scans

For power users who need flags not covered by the dedicated tools:

# Aggressive scan with version detection
python3 $MCP_CALL "python3 -u $NMAP_MCP_SCRIPT" nmap_custom_scan '{"target":"192.168.1.1","flags":"-A -T4"}'

# Scan specific ports with timing template
python3 $MCP_CALL "python3 -u $NMAP_MCP_SCRIPT" nmap_custom_scan '{"target":"10.0.0.0/24","flags":"-sS -p 22,80,443 -T3 --open"}'

# Idle scan using a zombie host
python3 $MCP_CALL "python3 -u $NMAP_MCP_SCRIPT" nmap_custom_scan '{"target":"192.168.1.1","flags":"-sI 192.168.1.254"}'

# IPv6 scan
python3 $MCP_CALL "python3 -u $NMAP_MCP_SCRIPT" nmap_custom_scan '{"target":"fd00:cc:1:2::1","flags":"-6 -sT -p 179,22,80"}'

Safety: The following are blocked in custom scans:

• Shell metacharacters (;, &, |, `, $, etc.)
• Output-writing flags (-oN, -oX, -oG, -oA)
• Path-based flags (--datadir, --servicedb, --script with path)

Use the dedicated nmap_script_scan or nmap_vuln_scan tools for NSE scripts.

Scan History

List Recent Scans

python3 $MCP_CALL "python3 -u $NMAP_MCP_SCRIPT" nmap_list_scans '{"limit":20}'

Returns newest-first list with scan_id, timestamp, tool used, and target.

Retrieve a Specific Scan

python3 $MCP_CALL "python3 -u $NMAP_MCP_SCRIPT" nmap_get_scan '{"scan_id":"20250307_143022_a1b2c3"}'

Returns the full scan result as originally captured.

Workflow: Before/After Comparison

When validating a change:

1. Before change: Run a baseline scan and note the scan_id
2. Make the change (firewall rule, service deploy, etc.)
3. After change: Run the same scan again
4. Compare: Retrieve both scans and diff the open ports / services

# Baseline
python3 $MCP_CALL "python3 -u $NMAP_MCP_SCRIPT" nmap_top_ports '{"target":"192.168.1.1","count":1000}'
# Note: scan_id from output, e.g. "20250307_140000_abc123"

# ... make changes ...

# Post-change
python3 $MCP_CALL "python3 -u $NMAP_MCP_SCRIPT" nmap_top_ports '{"target":"192.168.1.1","count":1000}'

# Retrieve both for comparison
python3 $MCP_CALL "python3 -u $NMAP_MCP_SCRIPT" nmap_get_scan '{"scan_id":"20250307_140000_abc123"}'
python3 $MCP_CALL "python3 -u $NMAP_MCP_SCRIPT" nmap_get_scan '{"scan_id":"20250307_141500_def456"}'

Tool Parameters

nmap_custom_scan

• target (required): IP, hostname, or CIDR range
• flags (required): Raw nmap flags (do NOT include the target in flags)

nmap_list_scans

• limit (optional): Max number of scans to return (default: 20, newest first)

nmap_get_scan

• scan_id (required): The scan_id returned by any scan tool or nmap_list_scans

Important Rules

• Custom scans still enforce the CIDR allowlist — out-of-scope targets are rejected
• Every scan (including custom) is recorded in the audit log
• All scan results are saved to disk and retrievable by scan_id
• Do NOT put the target in the flags parameter — it's added automatically
• Shell injection is blocked — forbidden characters are rejected
