Retrieve the full parent document by its ID. This provides a more complete answer to some questions.
AI agents call get_parent_document to retrieve information from AVS Document Search System without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves data (a parent document) based on an identifier without any side effects, modifications, or code execution. It is a straightforward query operation analogous to a GET request in REST APIs. The severity is low because retrieving existing documents poses minimal risk unless the documents themselves contain highly sensitive data, but the tool's function is fundamentally a safe read operation.
From the tool's definition Tool description states 'Retrieve the full parent document by its ID' — a retrieval operation with no modification, deletion, or execution semantics.
Attacks that exploit this kind of access
Retrieve the full parent document by its ID. This provides a more complete answer to some questions. It is categorised as a Read tool in the AVS Document Search System MCP Server, which means it retrieves data without modifying state.
Register the AVS Document Search System MCP server in PolicyLayer and add a rule for get_parent_document: 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 AVS Document Search System. Nothing to install.
get_parent_document 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_parent_document 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_parent_document. 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_parent_document is provided by the AVS Document Search System MCP server (patw/avs-docs-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
