What watchers.ioc-reputation does on Mcp
AI agents call watchers.ioc-reputation to retrieve information from Mcp without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Attacks that exploit this kind of access
The rule that runs watchers.ioc-reputation safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Mcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For watchers.ioc-reputation, this is the rule to start with:
watchers.ioc-reputation 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 Mcp, apply this rule, and every watchers.ioc-reputation call is checked against it from then on.
