Answer a question using retrieval-augmented generation.
AI agents call rag_answer to retrieve information from MCP Math Calculator Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information from a RAG system to answer questions. It queries data without creating, modifying, deleting, or executing arbitrary code. The operation is informational and has no side effects on the underlying data or system state. Classified as Read with low severity due to minimal blast radius if misused.

Answer a question using retrieval-augmented generation. It is categorised as a Read tool in the MCP Math Calculator Server MCP Server, which means it retrieves data without modifying state.
Register the MCP Math Calculator Server MCP server in PolicyLayer and add a rule for rag_answer: 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 MCP Math Calculator Server. Nothing to install.
rag_answer 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 rag_answer 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 rag_answer. 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.
