Extract images from a PDF document as base64-encoded data. Extracts embedded images from specified or all pages. Returns image metadata (dimensions, color space) along with raw pixel data in base64. Args: - file_path (string): Absolute path to a local PDF file - pages (string, optional): Page range. Format:. It is categorised as a Read tool in the Pdf Reader MCP Server, which means it retrieves data without modifying state.
Register the Pdf Reader MCP server in PolicyLayer and add a rule for read_images: 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 Pdf Reader. Nothing to install.
read_images 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 read_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 read_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.
read_images is provided by the Pdf Reader MCP server (shuji-bonji/pdf-reader-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
