Calculate optimal chunk ranges for processing a large PDF. Returns page ranges that fit within character limits.
AI agents call pdf_get_chunks to retrieve information from PDF 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 calculates metadata about PDF structure (page ranges and character limits) to optimize downstream processing. It does not modify, delete, execute external operations, or create financial obligations. The capability is purely analytical and read-only.
From the tool's definition Tool description states it 'Calculate[s] optimal chunk ranges' and 'Returns page ranges' — a computational operation with no side effects.
Attacks that exploit this kind of access
Calculate optimal chunk ranges for processing a large PDF. Returns page ranges that fit within character limits. It is categorised as a Read tool in the PDF MCP Server MCP Server, which means it retrieves data without modifying state.
Register the PDF MCP Server MCP server in PolicyLayer and add a rule for pdf_get_chunks: 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 MCP Server. Nothing to install.
pdf_get_chunks 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 pdf_get_chunks 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 pdf_get_chunks. 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.
pdf_get_chunks is provided by the PDF MCP Server MCP server (volume19/pdf-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
