What load_tool_group does on Metis Public Health
AI agents call load_tool_group to retrieve information from Metis Public Health without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why load_tool_group is rated Low
The tool's function is informational: it enumerates and loads tool definitions from a pre-defined group. No data is created, modified, destroyed, or executed. The worst outcome of misuse is that an agent gains access to a list of available tools, which is a read-level risk in a local-first, user-controlled environment. Severity is low because the blast radius is limited to tool discovery within the user's own system.
From the tool's definition load_tool_group 'Load every tool in a named group at once' — this operation retrieves/queries tool metadata from a named group without modifying, deleting, or executing external operations.

The rule that runs load_tool_group 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 load_tool_group, this is the rule to start with:
load_tool_group is read-only, so it stays allowed. 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 load_tool_group call is checked against it from then on.
