WHAT IT DOES

What pdf-metadata does on MCP PDF Reader

AI agents call pdf-metadata to retrieve information from MCP PDF Reader without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why pdf-metadata is rated Low

Metadata retrieval from PDFs is a read-only operation with no side effects. It queries document properties without modifying, executing, or deleting anything. The empty description lowers confidence slightly, but the naming convention and server context strongly indicate this is a straightforward metadata extraction tool. Severity is low because metadata exposure poses minimal risk even if misused by an AI agent.

From the tool's definition Tool name 'pdf-metadata' combined with server description stating it 'retrieves metadata through the Model Context Protocol'. The sibling tools (ocr-pdf-auto-legacy, read-pdf, search-pdf, etc.) are all read operations.
