Extract document structure including headers, sections, and metadata
AI agents call get_document_structure to retrieve information from MCP PDF 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 document structure, metadata, headers, and sections without creating, modifying, deleting, or executing any operations. It performs analysis and extraction tasks typical of Read category operations. No side effects or state changes occur on the document or system.
From the tool's definition Tool name 'get_document_structure' and description 'Extract document structure including headers, sections, and metadata' indicate data retrieval with no modification.
Documented attack patterns abuse exactly the kind of access get_document_structure gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MCP PDF, and nothing reaches the server without passing your rules. This is the rule we recommend for get_document_structure:
{
"version": "1",
"default": "deny",
"tools": {
"get_document_structure": {}
}
}get_document_structure is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Extract document structure including headers, sections, and metadata. It is categorised as a Read tool in the MCP PDF MCP Server, which means it retrieves data without modifying state.
Register the MCP PDF MCP server in PolicyLayer and add a rule for get_document_structure: 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 MCP PDF. Nothing to install.
get_document_structure 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 get_document_structure 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 get_document_structure. 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.
get_document_structure is provided by the MCP PDF MCP server (rsp2k/mcp-pdf). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from MCP PDF, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
