Remove public access to a Metabase card by deleting its public URL (requires admin privileges) - use this to revoke external access to sensitive data, clean up unused public links, or update security permissions
AI agents call delete_card_public_link to permanently remove resources in Metabase MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool permanently deletes a public link/URL for a Metabase card. While the underlying card data is not destroyed, the public link itself is irreversibly removed (requires admin privileges). This is a destructive action — the link cannot be restored, only recreated. Misuse could inadvertently revoke legitimate external access to shared analytics.
From the tool's definition 'deleting its public URL' and 'revoke external access' — the action irreversibly removes the public link

It is categorised as a Destructive tool in the Metabase MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Metabase MCP Server MCP server in PolicyLayer and add a rule for delete_card_public_link: 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 Metabase MCP Server. Nothing to install.
delete_card_public_link 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_card_public_link 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_card_public_link. 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_card_public_link is provided by the Metabase MCP Server MCP server (thangnm93/metabase-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
