What publish_course does on Metis Public Health
AI agents use publish_course to create or update resources in Metis Public Health, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Metis Public Health environment.
Why publish_course is rated Medium
Publishing a course typically involves creating or modifying structured content that becomes available to others—a Write operation. The absence of a description prevents confirmation of whether publication is reversible (could be updated/unpublished) or has broader distribution effects.
From the tool's definition Tool name is 'publish_course' which strongly suggests creating or making content available (publish); however, the description is empty, limiting certainty about the exact scope and reversibility.
Attacks that exploit this kind of access
The rule that runs publish_course safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Metis Public Health, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For publish_course, this is the rule to start with:
publish_course 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Metis Public Health, apply this rule, and every publish_course call is checked against it from then on.
