HTML page: https://policylayer.com/tools/hooker-dev-hailey-mcp/check-url-slug ## Facts - Tool: `check_url_slug` - Server: GoHighLevel MCP Server (`hooker-dev/hailey-mcp`) — https://policylayer.com/tools/hooker-dev-hailey-mcp.md - Homepage: https://github.com/hooker-dev/hailey-mcp - Risk category: Read (Low risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Allowed ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "check_url_slug", "arguments": {} } } ``` ## Why check_url_slug is rated Low This tool performs a lookup/query operation to verify whether a URL slug exists or is available. It does not create, modify, delete, execute code, or move money. It purely returns availability status information to inform subsequent actions. The blast radius of misuse is minimal—an agent could spam checks, but this causes no actual data modification or system harm. From the tool's own definition: "check_url_slug checks if a URL slug is available. The verb 'check' and the intent to verify availability before creation indicates a query operation with no side effects. It retrieves information about slug availability status." ## Use case AI agents call check_url_slug to retrieve information from GoHighLevel MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere. ## Recommended policy (PolicyLayer) Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches GoHighLevel MCP Server: ```json { "version": "1", "default": "deny", "tools": { "check_url_slug": {} } } ``` ## Other tools on GoHighLevel MCP Server (254) - `bulk_delete_social_posts` — Destructive — https://policylayer.com/tools/hooker-dev-hailey-mcp/bulk-delete-social-posts.md - `cancel_scheduled_email` — Destructive — https://policylayer.com/tools/hooker-dev-hailey-mcp/cancel-scheduled-email.md - `cancel_scheduled_message` — Destructive — https://policylayer.com/tools/hooker-dev-hailey-mcp/cancel-scheduled-message.md - `delete_appointment` — Destructive — https://policylayer.com/tools/hooker-dev-hailey-mcp/delete-appointment.md - `delete_appointment_note` — Destructive — https://policylayer.com/tools/hooker-dev-hailey-mcp/delete-appointment-note.md - `delete_calendar` — Destructive — https://policylayer.com/tools/hooker-dev-hailey-mcp/delete-calendar.md - `delete_calendar_group` — Destructive — https://policylayer.com/tools/hooker-dev-hailey-mcp/delete-calendar-group.md - `delete_calendar_notification` — Destructive — https://policylayer.com/tools/hooker-dev-hailey-mcp/delete-calendar-notification.md - `delete_calendar_resource_equipment` — Destructive — https://policylayer.com/tools/hooker-dev-hailey-mcp/delete-calendar-resource-equipment.md - `delete_calendar_resource_room` — Destructive — https://policylayer.com/tools/hooker-dev-hailey-mcp/delete-calendar-resource-room.md - `delete_contact` — Destructive — https://policylayer.com/tools/hooker-dev-hailey-mcp/delete-contact.md - `delete_contact_note` — Destructive — https://policylayer.com/tools/hooker-dev-hailey-mcp/delete-contact-note.md - `delete_contact_task` — Destructive — https://policylayer.com/tools/hooker-dev-hailey-mcp/delete-contact-task.md - `delete_conversation` — Destructive — https://policylayer.com/tools/hooker-dev-hailey-mcp/delete-conversation.md - `delete_coupon` — Destructive — https://policylayer.com/tools/hooker-dev-hailey-mcp/delete-coupon.md - `delete_custom_provider_integration` — Destructive — https://policylayer.com/tools/hooker-dev-hailey-mcp/delete-custom-provider-integration.md - `delete_email_template` — Destructive — https://policylayer.com/tools/hooker-dev-hailey-mcp/delete-email-template.md - `delete_invoice_template` — Destructive — https://policylayer.com/tools/hooker-dev-hailey-mcp/delete-invoice-template.md - `delete_location` — Destructive — https://policylayer.com/tools/hooker-dev-hailey-mcp/delete-location.md - `delete_location_custom_field` — Destructive — https://policylayer.com/tools/hooker-dev-hailey-mcp/delete-location-custom-field.md - `delete_location_custom_value` — Destructive — https://policylayer.com/tools/hooker-dev-hailey-mcp/delete-location-custom-value.md - `delete_location_tag` — Destructive — https://policylayer.com/tools/hooker-dev-hailey-mcp/delete-location-tag.md - `delete_location_template` — Destructive — https://policylayer.com/tools/hooker-dev-hailey-mcp/delete-location-template.md - `delete_media_file` — Destructive — https://policylayer.com/tools/hooker-dev-hailey-mcp/delete-media-file.md - `delete_object_record` — Destructive — https://policylayer.com/tools/hooker-dev-hailey-mcp/delete-object-record.md - `delete_opportunity` — Destructive — https://policylayer.com/tools/hooker-dev-hailey-mcp/delete-opportunity.md - `delete_social_account` — Destructive — https://policylayer.com/tools/hooker-dev-hailey-mcp/delete-social-account.md - `delete_social_post` — Destructive — https://policylayer.com/tools/hooker-dev-hailey-mcp/delete-social-post.md - `ghl_delete_association` — Destructive — https://policylayer.com/tools/hooker-dev-hailey-mcp/ghl-delete-association.md - `ghl_delete_custom_field` — Destructive — https://policylayer.com/tools/hooker-dev-hailey-mcp/ghl-delete-custom-field.md - …and 224 more: https://policylayer.com/tools/hooker-dev-hailey-mcp.md ## For agents This record is a snapshot.
