header-test-mcp
Verified Safeby matsjfunke
Overview
An MCP server designed for debugging custom header implementations in MCP hosts/clients by providing a tool to retrieve request headers.
Installation
pnpm dSecurity Notes
The server enables wildcard CORS ('Access-Control-Allow-Origin: *'), which is a security risk in production but acceptable for its stated debugging purpose. The `currentRequestHeaders` global variable can be overwritten by concurrent requests, potentially leading to stale information for debugging, but does not pose a direct critical security vulnerability like data leakage to unauthorized parties.
