getDocumentMetadata
AI agents call getDocumentMetadata to retrieve information from RAG MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Metadata retrieval is a read-only operation with no side effects. It queries existing document metadata without creating, modifying, deleting, or executing anything. The blast radius if misused is minimal—an agent could only access information already stored in the system.
From the tool's definition Tool name 'getDocumentMetadata' indicates metadata retrieval. The server is a RAG system focused on document storage, embedding, and retrieval. Sibling tools like 'listDocuments', 'retrieveDocs', and 'collectionStats' are clearly Read operations.
Attacks that exploit this kind of access
getDocumentMetadata. It is categorised as a Read tool in the RAG MCP Server MCP Server, which means it retrieves data without modifying state.
Register the RAG MCP Server MCP server in PolicyLayer and add a rule for getDocumentMetadata: 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 RAG MCP Server. Nothing to install.
getDocumentMetadata 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 getDocumentMetadata 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 getDocumentMetadata. 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.
getDocumentMetadata is provided by the RAG MCP Server MCP server (nsantra/rag-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
