AI agents call pruva_ask to retrieve information from Pruva without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and analyzes information from Pruva (features, documents, relations) without creating, modifying, or deleting data. The explicit 'read-only' designation and guarantee that it 'cannot modify anything' place it squarely in the Read category with low severity, as misuse would only expose information rather than cause operational or financial harm.
From the tool's definition Tool description states 'read-only question' and 'cannot modify anything'. The tool name 'ask' and capability to 'analyse features, documents, and relations' are consistent with data retrieval without side effects.
Attacks that exploit this kind of access
Ask the Pruva analysis agent a read-only question about a product. The agent can analyse features, documents, and relations but cannot modify anything. It is categorised as a Read tool in the Pruva MCP Server, which means it retrieves data without modifying state.
Register the Pruva MCP server in PolicyLayer and add a rule for pruva_ask: 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 Pruva. Nothing to install.
pruva_ask 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 pruva_ask 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 pruva_ask. 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.
pruva_ask is provided by the Pruva MCP server (pruva-ai/pruva-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
