Get the audit trail for a secret (requires owner key).
AI agents call audit_secret to retrieve information from Sirr MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves audit/history information about a secret's access and modifications. It is purely informational with no side effects—it queries existing audit logs rather than creating, modifying, or deleting data. The requirement for an 'owner key' restricts access but does not change the read-only nature of the operation. Confidence is high because the description unambiguously indicates data retrieval.
From the tool's definition Tool name 'audit_secret' and description 'Get the audit trail for a secret' indicate a retrieval operation with no modification capabilities. The phrase 'audit trail' explicitly describes historical logging/inspection data, not creation or deletion of secrets.
Attacks that exploit this kind of access
Get the audit trail for a secret (requires owner key). It is categorised as a Read tool in the Sirr MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Sirr MCP Server MCP server in PolicyLayer and add a rule for audit_secret: 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 Sirr MCP Server. Nothing to install.
audit_secret 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 audit_secret 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 audit_secret. 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.
audit_secret is provided by the Sirr MCP Server MCP server (sirrlock/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
