List all secrets owned by the calling key.
AI agents call list_secrets 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 or queries secret metadata without modifying, deleting, or executing anything. It fits the Read category as a listing operation. Severity is low because metadata-only enumeration has limited blast radius compared to actual secret value exposure, and access is scoped to 'calling key' ownership.
From the tool's definition Tool name 'list_secrets' and description 'List all secrets owned by the calling key' indicate a retrieval operation with no modification.
Attacks that exploit this kind of access
List all secrets owned by the calling 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 list_secrets: 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.
list_secrets 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 list_secrets 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 list_secrets. 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.
list_secrets 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.
list_secrets is one line of Sirr MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
