Delete a specific user/vehicle connection for the application.
AI agents call delete_connection to permanently remove resources in Smartcar MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly deletes data (a user/vehicle connection) and cannot be undone. Destructive is the appropriate category per the severity hierarchy. While the blast radius is contained to a single connection rather than entire users/vehicles, an AI agent could maliciously delete connections affecting service availability or user access to their vehicle integrations, warranting 'high' severity.
From the tool's definition Tool name contains 'delete' and description explicitly states 'Delete a specific user/vehicle connection'. The action is irreversible—removing a connection permanently severs the relationship between a user and their vehicle in the system.
Attacks that exploit this kind of access
Delete a specific user/vehicle connection for the application. It is categorised as a Destructive tool in the Smartcar MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Smartcar MCP Server MCP server in PolicyLayer and add a rule for delete_connection: 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.
delete_connection is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the delete_connection 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 delete_connection. 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.
delete_connection 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.
delete_connection is one line of Smartcar 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.
