Read a PDF file from disk and return its text content
AI agents call read_pdf to retrieve information from PDF-Tools MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries PDF content from disk, returning text without creating, modifying, deleting, or executing anything. It is a straightforward read operation with minimal risk—the only potential concern would be unauthorized access to sensitive PDF files, but that is a deployment/access-control issue rather than an inherent tool capability issue.
From the tool's definition Tool name is 'read_pdf' and description states 'Read a PDF file from disk and return its text content'. The verb 'Read' and the action of returning content without modification indicates data retrieval with no side effects.

Register the PDF-Tools MCP Server MCP server in PolicyLayer and add a rule for read_pdf: 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-Tools MCP Server. Nothing to install.
read_pdf 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_pdf 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_pdf. 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_pdf is provided by the PDF-Tools MCP Server MCP server (theorhd/pdftools-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
