List previously shared secrets and their current status — view counts, expiry, and whether they
AI agents call list_secrets to retrieve information from Vaulted 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 and queries information about secrets (view counts, expiry status) without creating, modifying, deleting, or executing anything. It has no side effects and fits the Read category definition: 'retrieves or queries data; no side effects (search, list, get, fetch)'.
From the tool's definition Tool name is 'list_secrets' and description states 'List previously shared secrets and their current status — view counts, expiry, and whether they'. The verb 'list' and 'view' indicate read-only retrieval of metadata about secrets without modification.
Attacks that exploit this kind of access
List previously shared secrets and their current status — view counts, expiry, and whether they. It is categorised as a Read tool in the Vaulted MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Vaulted 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 Vaulted 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 Vaulted MCP Server MCP server (vaulted-fyi/vaulted-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
