What search_tabs does on AirMCP
AI agents call search_tabs to retrieve information from AirMCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why search_tabs is rated Low
This tool queries the state of open Safari tabs and returns matching results based on search criteria. It is a passive retrieval operation with no side effects, no data modification, and no execution of external commands. It fits squarely within the Read category.
From the tool's definition "Search open Safari tabs by title or URL keyword" — retrieves information about existing tabs without modifying, deleting, or executing actions.
Attacks that exploit this kind of access
The rule that runs search_tabs safely
PolicyLayer is an MCP gateway: it sits between your AI agents and AirMCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For search_tabs, this is the rule to start with:
search_tabs 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 AirMCP, apply this rule, and every search_tabs call is checked against it from then on.

search_tabs is provided by the Air MCP server (airmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
