Network Diagram Mcp
Bridges Claude to a live browser tab running NetMap at map.den.dance. The 44 MCP tools let your agent build network diagrams by adding nodes and connections, import nmap XML or CSV inventories with auto-detected column mapping, run smart layouts (force-directed, cluster by type or connection), and export to PNG or PDF. Clicking ports on node cards launches your local SSH client, psql, or redis-cli directly. The package also registers OS-level URL handlers so ssh://, postgres://, and redis:// links anywhere on your system spawn an in-app picker of installed clients. Everything runs local-first in localStorage with no login. Useful when you're documenting infrastructure, onboarding on a new network, or turning scan output into a visual map you can hand off.
