WHAT IT DOES

What session_save does on Hamza Agent Hub 252

AI agents use session_save to create or update resources in Hamza Agent Hub 252, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Hamza Agent Hub 252 environment.

RISK

Why session_save is rated Medium

This tool creates or modifies persisted session data, which is a Write operation. The state being saved includes agent definitions and swarm topology that could affect subsequent agent behavior. Severity is medium because while the operation is reversible (session state can be overwritten), improper saves could corrupt agent coordination or leave the system in an inconsistent state.

From the tool's definition Tool description states 'Save current session state' and mentions 'restoring agent definitions, swarm topology, memory store, breaker history.' The verb 'save' and the explicit purpose of persisting state indicates data creation/modification.

RECOMMENDED RULE

The rule that runs session_save safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Hamza Agent Hub 252, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For session_save, this is the rule to start with:

session_save Rate-limited

session_save 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.
