RISK

Why post_workroom_message is rated Medium

This tool creates new data (messages) within an internal communication system. It is categorized as Write rather than Execute because it performs a simple, bounded content creation action without triggering external operations or side effects. The internal-only nature and reversibility keep severity low. No customer communication, financial impact, or destructive operations are involved.

From the tool's definition Tool description states 'Post an internal message' to 'Workroom thread' with explicit note 'This does not send anything to customers.' The action is to create/add a message, which is reversible (messages can be edited or deleted).

RECOMMENDED RULE

The rule that runs post_workroom_message safely

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

post_workroom_message Rate-limited

post_workroom_message 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.
