Nmap MCP Server
MCP server wrapping nmap — the industry-standard network scanner — enabling AI agents to perform network discovery, port scanning, service version detection, OS fingerprinting, and script-based vulnerability enumeration through structured MCP tool calls. Integrates nmap's comprehensive scanning capabilities into agent-driven security assessment workflows.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Dual-use security tool. Authorized security testing only. Network scanning without permission is illegal. Scan activity is visible to targets. Use in controlled pentesting environments only.
⚡ Reliability
Best When
An authorized penetration tester or security researcher wants AI-assisted network scanning — combining nmap's comprehensive capabilities with agent reasoning for structured security assessments.
Avoid When
You don't have explicit authorization to scan the target network — unauthorized scanning is illegal in most jurisdictions. Always obtain written permission before use.
Use Cases
- • Running network discovery scans from authorized penetration testing agents
- • Identifying open ports and services from security assessment agents
- • Detecting OS versions and service fingerprints from reconnaissance agents
- • Automating vulnerability enumeration with nmap scripts from security audit agents
Not For
- • Scanning networks or hosts without explicit written authorization — ILLEGAL without permission
- • Production monitoring (use dedicated network monitoring tools, not nmap for this)
- • Automated bulk internet scanning (violates ToS of most networks and ISPs)
Interface
Authentication
No authentication — local tool. Nmap itself must be installed. Some scan types require root/admin privileges for raw packet access.
Pricing
Free open source. Nmap is free and open source. This MCP server is also free.
Agent Metadata
Known Gotchas
- ⚠ CRITICAL LEGAL RISK: Unauthorized network scanning is a crime in most jurisdictions — always obtain written authorization first
- ⚠ Some scan types (SYN scan, OS detection) require root/admin privileges — run with appropriate permissions
- ⚠ Aggressive scans can trigger IDS/IPS alerts and disrupt network services — use timing flags carefully
- ⚠ Long scan timeouts — implement appropriate agent timeouts for large network ranges
- ⚠ Nmap must be installed separately (not bundled with the MCP server)
