WHAT IT DOES

What register-test-session does on Frontmcp

AI agents use register-test-session 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 register-test-session is rated Medium

The tool creates/registers a new fake session, which is a write operation (creating session state). While labeled for testing/isolation purposes, registering sessions could be misused to create unauthorized session contexts. Severity is medium because fake sessions in a real environment could bypass authentication or session controls, but the 'fake' and 'testing' framing suggests limited blast radius in production.

RECOMMENDED RULE

The rule that runs register-test-session 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 register-test-session, this is the rule to start with:

register-test-session 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.
