ssl_switch_ca · Web Proxy MCP Server MCP: Risk & Policy

WHAT IT DOES

What ssl_switch_ca does on Web Proxy MCP Server

AI agents invoke ssl_switch_ca to trigger actions in Web Proxy MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why ssl_switch_ca needs a policy

Switching the Certificate Authority on an HTTPS proxy is an operational action that affects how SSL/TLS traffic is intercepted and decrypted. It doesn't merely read data, nor does it irreversibly delete anything, but it triggers an external configuration change with significant security implications — altering which CA signs intercepted certificates could break TLS for all proxied clients or enable MitM attacks if…

From the tool's definition 'Switch to a different Certificate Authority' — changes the active CA used for SSL/TLS interception
