WHAT IT DOES

What pki-generate-intermediate does on Vault MCP Server (mschuchard)

AI agents invoke pki-generate-intermediate to trigger actions in Vault MCP Server (mschuchard). 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 pki-generate-intermediate needs a policy

Based on the tool name, this likely triggers Vault's PKI engine to generate an intermediate CA certificate or CSR, which is an operational action (executing a cryptographic generation process) rather than a simple read or write. Generating an intermediate CA is significant because it creates a certificate authority that can issue certificates, but the description is empty so confidence is reduced.

From the tool's definition Tool name 'pki-generate-intermediate' on a Vault MCP server managing PKI secret engines; description is empty and uninformative.
