WHAT IT DOES

What update_session_type does on Businys

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

RISK

Why update_session_type is rated Medium

This tool modifies session type configuration, which is reversible. It does not execute arbitrary code, delete data irreversibly, or involve financial transactions. The Write category is appropriate. Severity is medium because session type changes could affect multiple sessions or business workflows if misconfigured by an agent, but the impact is recoverable via another update or rollback.

From the tool's definition Tool name 'update_session_type' and description 'Update an existing session type' clearly indicate modification of existing data. The 'update' verb is a classic Write operation.

update_session_type Rate-limited

update_session_type 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.
