Answers a question about the active codebase using RAG.
AI agents call ask_question to retrieve information from Python Codebase Analysis RAG System without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool performs information retrieval against a vector database to answer natural language questions about code structure and functionality. This is a read-only operation with no side effects, modifications, or code execution capabilities. The RAG system synthesizes existing indexed information without altering the codebase or triggering external operations.
From the tool's definition Tool description states it 'Answers a question about the active codebase using RAG' — a pure query operation that retrieves and synthesizes information without modifying, executing, or deleting any code or data.
Attacks that exploit this kind of access
Answers a question about the active codebase using RAG. It is categorised as a Read tool in the Python Codebase Analysis RAG System MCP Server, which means it retrieves data without modifying state.
Register the Python Codebase Analysis RAG System MCP server in PolicyLayer and add a rule for ask_question: 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 Python Codebase Analysis RAG System. Nothing to install.
ask_question 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 ask_question 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 ask_question. 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.
ask_question is provided by the Python Codebase Analysis RAG System MCP server (shervinemp/codebasemcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
