List secrets for a Smartcar application. Secret values are not included in the response.
AI agents call list_application_secrets to retrieve information from Smartcar 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 metadata about application secrets (names, identifiers) but not the actual secret values themselves, classifying it as a Read operation. However, severity is marked high because: (1) knowing which secrets exist and their identifiers could enable reconnaissance for credential theft attacks, (2) it exposes the existence of sensitive credentials, and (3) in context of a vehicle API server,…
From the tool's definition Tool name 'list_application_secrets' and description states 'List secrets for a Smartcar application.' The description explicitly confirms secret values are NOT included in the response, making this a read/query operation with no modification capability.
Attacks that exploit this kind of access
List secrets for a Smartcar application. Secret values are not included in the response. It is categorised as a Read tool in the Smartcar MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Smartcar MCP Server MCP server in PolicyLayer and add a rule for list_application_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 Smartcar MCP Server. Nothing to install.
list_application_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_application_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_application_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_application_secrets is provided by the Smartcar MCP Server MCP server (thachdosc/smartcar-mcp-test). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
