AI agents call get_definitions to retrieve information from Pdf Spec without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only query operation on structured specification data. It retrieves and returns term definitions from a specific section of an ISO PDF specification document. There are no side effects, data modifications, code execution, financial implications, or destructive operations. The tool's purpose is purely informational retrieval, making it a Read category tool with low risk.
From the tool's definition Tool description states 'Get term definitions' which is a retrieval operation with no modification or execution capability. The tool accesses Section 3 of the PDF specification document to fetch definitional data.
Attacks that exploit this kind of access
Get term definitions from Section 3 of the PDF specification (ISO 32000-2). It is categorised as a Read tool in the Pdf Spec MCP Server, which means it retrieves data without modifying state.
Register the Pdf Spec MCP server in PolicyLayer and add a rule for get_definitions: 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 Spec. Nothing to install.
get_definitions 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_definitions 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_definitions. 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_definitions is provided by the Pdf Spec MCP server (shuji-bonji/pdf-spec-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
