Search for documents using semantic similarity
AI agents call search_documents to retrieve information from RagDocs MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
search_documents retrieves and queries data without creating, modifying, deleting, or executing operations. It is a pure information retrieval function that matches the Read category definition of 'retrieves or queries data; no side effects (search, list, get, fetch).' The low severity reflects minimal blast radius if misused by an AI agent—worst case is exposure of indexed document content.
From the tool's definition Tool description states 'Search for documents using semantic similarity' — a read-only retrieval operation. No modifications, deletions, or side effects are described.
Attacks that exploit this kind of access
Search for documents using semantic similarity. It is categorised as a Read tool in the RagDocs MCP Server MCP Server, which means it retrieves data without modifying state.
Register the RagDocs MCP Server MCP server in PolicyLayer and add a rule for search_documents: 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 RagDocs MCP Server. Nothing to install.
search_documents 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 search_documents 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 search_documents. 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.
search_documents is provided by the RagDocs MCP Server MCP server (mcpflow/ragdocs). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
