Read a document from the configured knowledge directory.
AI agents call get_document to retrieve information from AI App MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves documents from a knowledge base without altering, deleting, or executing anything. It is clearly a Read operation. Severity is medium rather than low because: (1) it accesses a configured knowledge directory, which may contain sensitive information depending on deployment context, and (2) in a RAG system, unrestricted document retrieval could leak proprietary training data, business intelligence,…
From the tool's definition Tool description states 'Read a document from the configured knowledge directory' — explicit read operation with no modification capability.
Attacks that exploit this kind of access
Read a document from the configured knowledge directory. It is categorised as a Read tool in the AI App MCP MCP Server, which means it retrieves data without modifying state.
Register the AI App MCP server in PolicyLayer and add a rule for get_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 AI App MCP. Nothing to install.
get_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_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_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_document is provided by the AI App MCP server (yh008/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
