WHAT IT DOES

What keyway_generate does on Keyway MCP Server

AI agents use keyway_generate to create or update resources in Keyway MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Keyway MCP Server environment.

WHY IT NEEDS A POLICY

Why keyway_generate needs a policy

This tool creates and persists new secrets in a vault, which is a reversible write operation. While secrets are sensitive, the tool itself does not execute arbitrary code, delete data, or move money. The severity is medium because misuse could lead to generation of many secrets that clutter the vault or exhaust quota limits, but the operation is reversible and doesn't expose values in conversation.

From the tool's definition Tool description states 'Generate a secure secret and store it directly in the vault', which indicates creation and storage of data.
