List all images embedded in a PDF file with their metadata (page, dimensions, type)
AI agents call list_pdf_images to retrieve information from MCP PDF Reader without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only queries and returns information about embedded images in a PDF document. It performs no data modification, deletion, execution, or financial operations. The blast radius of misuse is minimal—an AI agent could at most enumerate image metadata from documents it has access to, which poses negligible security risk.
From the tool's definition The tool 'list_pdf_images' retrieves metadata about images embedded in a PDF file (page, dimensions, type). The verb 'list' and the action of retrieving metadata without modification or side effects clearly indicate a read-only operation.

Yes. Add a rate_limit block to the list_pdf_images 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 list_pdf_images. 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.
list_pdf_images is provided by the MCP PDF Reader MCP server (rturv/mcp-pdf-reader). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
list_pdf_images is one line of MCP PDF Reader's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
