WHAT IT DOES

What authorize-app does on Frontmcp

AI agents use authorize-app to create or update resources in Frontmcp, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Frontmcp environment.

RISK

Why authorize-app is rated Medium

This tool grants authorization/access rights to an application for a vault entry, which is a write operation that modifies access control or permissions. Misuse could allow unauthorized applications to gain access to sensitive vault credentials or secrets, making the blast radius high. It is reversible (authorization can be revoked), so it falls under Write rather than Destructive.

RECOMMENDED RULE

The rule that runs authorize-app safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Frontmcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For authorize-app, this is the rule to start with:

authorize-app Rate-limited

authorize-app stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
