Show PDF search index statistics (file count, page count, DB size, renderer).
AI agents call stats to retrieve information from Pdf Search without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves read-only metadata and statistics about the indexed PDF collection. It has no side effects, cannot modify data, and poses minimal risk if misused by an AI agent—the worst case would be surfacing harmless diagnostic information. It clearly falls under the Read category.
From the tool's definition Tool returns statistics about the PDF search index (file count, page count, DB size, renderer) with no capability to modify or delete data. The description uses 'Show' indicating query/retrieval only.
Attacks that exploit this kind of access
Show PDF search index statistics (file count, page count, DB size, renderer). It is categorised as a Read tool in the Pdf Search MCP Server, which means it retrieves data without modifying state.
Register the Pdf Search MCP server in PolicyLayer and add a rule for stats: 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 Search. Nothing to install.
stats 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 stats 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 stats. 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.
stats is provided by the Pdf Search MCP server (renvk/pdf-search-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
