WHAT IT DOES

What toggle_context does on Metis Public Health

AI agents use toggle_context 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.

RISK

Why toggle_context is rated Medium

The tool modifies the state of a specialist context by toggling it on or off. This is a reversible write operation (it can be toggled back), affecting system configuration rather than data. Misuse could disrupt agent routing or research workflows, warranting medium severity.

RECOMMENDED RULE

The rule that runs toggle_context 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 toggle_context, this is the rule to start with:

toggle_context Rate-limited

toggle_context 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.
