What reject_proposal does on Metis Public Health
AI agents use reject_proposal 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 reject_proposal is rated Medium
Based on naming convention and context of sibling tools (add_*, apply_proposal), this tool likely modifies proposal records in a reversible manner. Without an explicit description, confidence is reduced, but the 'reject' action implies state change rather than deletion (which would be Destructive) or mere querying (which would be Read).
From the tool's definition Tool name 'reject_proposal' suggests modifying the state of a proposal object (marking it as rejected), which is a reversible write operation. The description is empty, limiting certainty.
Attacks that exploit this kind of access
The rule that runs reject_proposal 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 reject_proposal, this is the rule to start with:
reject_proposal 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 reject_proposal call is checked against it from then on.
