What scan_document does on AirMCP
AI agents call scan_document 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 scan_document is rated Low
The tool retrieves and extracts information (text and structure) from a document image but does not create, modify, delete, or execute operations. It is purely analytical/informational, making it a Read category tool with low severity risk.
From the tool's definition Tool performs OCR text extraction from image files using Apple Vision framework—a query/read operation with no side effects, no data modification, and no execution of commands.
Attacks that exploit this kind of access
The rule that runs scan_document 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 scan_document, this is the rule to start with:
scan_document 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 scan_document call is checked against it from then on.

Register the Air MCP server in PolicyLayer and add a rule for scan_document: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches AirMCP. Nothing to install.
scan_document is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the scan_document 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 scan_document. 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.
scan_document 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.
