Securely run MCP servers with secret URLs and nginx

By PulseAugur Editorial · [1 sources] ·

This article details a method for securely running an MCP server behind a secret URL, primarily for use with Claude. The approach involves setting up the MCP server on a virtual private server, protected by nginx and a firewall, with the URL path acting as the sole authentication mechanism due to limitations in Claude's connector options. It also addresses potential issues like process spawning and memory pressure from concurrent sessions, and suggests disabling access logs for the secret URL to prevent it from becoming a side-channel leak. AI
