Ask a natural language question about the codebase and get relevant code fragments as context. Use this when you need to UNDERSTAND how something works, not just find it.
AI agents call ask_context to retrieve information from Contextflow without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs semantic search and retrieval of code context to answer questions. It queries a vectorized repository to return relevant code fragments, which is purely informational with no side effects, data modification, or external operations. This is a classic Read operation—retrieving and presenting existing data for understanding purposes.
From the tool's definition Tool description states 'Ask a natural language question about the codebase and get relevant code fragments as context' and explicitly says 'Use this when you need to UNDERSTAND how something works, not just find it.' The verb 'ask' and 'get' indicate…
Attacks that exploit this kind of access
Ask a natural language question about the codebase and get relevant code fragments as context. Use this when you need to UNDERSTAND how something works, not just find it. It is categorised as a Read tool in the Contextflow MCP Server, which means it retrieves data without modifying state.
Register the Contextflow MCP server in PolicyLayer and add a rule for ask_context: 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 Contextflow. Nothing to install.
ask_context 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_context 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_context. 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_context is provided by the Contextflow MCP server (millermarru/mcpcontext). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
