What discover-tools does on Search
AI agents call discover-tools to retrieve information from Search without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why discover-tools is rated Low
The tool performs discovery of available tools on the server, which is a metadata query operation. 'List' falls squarely under Read category as it retrieves information about tools without modifying state or triggering external operations. The incomplete description ('that aren') does not provide additional concerning detail. No destructive, financial, or code execution capability is evident.
From the tool's definition Tool description explicitly indicates 'List and load additional tools' — listing is a retrieval operation with no side effects.
Attacks that exploit this kind of access
The rule that runs discover-tools safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Search, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For discover-tools, this is the rule to start with:
discover-tools 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 Search, apply this rule, and every discover-tools call is checked against it from then on.

Yes. Add a rate_limit block to the discover-tools rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for discover-tools. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
discover-tools is provided by the Search MCP server (Dave-London/Pare). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
