Nginx Proxy Manager MCP Server: Give AI Agents Access to Your Reverse Proxy

Why Give AI Access to Nginx Proxy Manager?

Nginx Proxy Manager is the simple reverse proxy GUI that handles SSL certificates, proxy hosts, redirects, and access lists for your self-hosted services. It makes exposing internal services with Let's Encrypt certificates as easy as filling out a form.

But when you're coding deployment scripts or debugging connectivity in Claude or Cursor, your AI assistant can't see your proxy configuration. It can't check which domains point where, verify SSL expiry dates, or review access list rules. You keep switching to the NPM dashboard.

With DataFaucet, you browse your Nginx Proxy Manager dashboard once and it captures the API calls as MCP tools. Now your AI coding assistant can check proxy hosts, SSL status, and redirect rules directly.

What AI Agents Can Do With Nginx Proxy Manager Access

Once DataFaucet creates an MCP server from your NPM session, AI agents can:

• List proxy hosts with domains, forward targets, and SSL status
• Check SSL certificate expiry dates across all hosts
• View redirection hosts with schemes and forwarding rules
• Review access lists with allowed/denied IP ranges
• Check stream hosts for TCP/UDP forwarding
• View dead hosts (404 pages) and custom locations
• Monitor certificate renewal status and errors

Setting Up Nginx Proxy Manager as an MCP Server with DataFaucet

Step 1: Browse Your NPM Dashboard

Open your Nginx Proxy Manager web interface and navigate through Proxy Hosts, Redirection Hosts, Streams, 404 Hosts, and Access Lists.

Step 2: DataFaucet Captures the API

DataFaucet's browser extension records the API calls your browser makes to NPM. Each call becomes a callable MCP tool with parameters and response types.

Step 3: Connect to Your AI Client

Add the generated MCP server to Claude Desktop, Cursor, or Windsurf. Your AI assistant can now query your reverse proxy configuration whenever it needs context.

Example: AI Checks Proxy Hosts

\\\`

User: What services am I proxying through NPM?

AI (via DataFaucet MCP): 12 proxy hosts configured:

• grafana.example.com → 192.168.1.10:3000 (SSL valid, expires in 58 days)
• nextcloud.example.com → 192.168.1.20:443 (SSL valid, expires in 62 days)
• jellyfin.example.com → 192.168.1.30:8096 (SSL valid, expires in 45 days)
• vaultwarden.example.com → 192.168.1.40:8080 (SSL expiring in 3 days!)

...8 more hosts

Example: AI Checks SSL Expiry

\\\`

User: Any SSL certificates expiring soon?

AI (via DataFaucet MCP): 1 certificate needs attention:

• vaultwarden.example.com: expires in 3 days (renewal may have failed)
• All other 11 certificates valid for 45+ days
• Last successful renewal: grafana.example.com (2 days ago)

Why Not Just Use the NPM API Directly?

Nginx Proxy Manager has an internal API, but it uses JWT token authentication with session management. Building a dedicated MCP server means handling login flows, token refresh, and keeping up with API changes across versions.

DataFaucet skips all of that. It watches what your browser does and replicates those exact calls as structured MCP tools. If NPM updates its interface, you just re-capture.

Works With Any MCP Client

The Nginx Proxy Manager MCP server created by DataFaucet works with:

• Claude Desktop and Claude Code
• Cursor (AI-powered editor)
• Windsurf (Codeium's IDE)
• Any MCP-compatible client

Your AI gets real-time data from your reverse proxy regardless of which tool you use.
