HTML page: https://policylayer.com/tools/basicmachines-co-open-ghl-mcp/get-custom-field ## Facts - Tool: `get_custom_field` - Server: GoHighLevel MCP Server (`basicmachines-co/open-ghl-mcp`) — https://policylayer.com/tools/basicmachines-co-open-ghl-mcp.md - Homepage: https://github.com/basicmachines-co/open-ghl-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": "get_custom_field", "arguments": {} } } ``` ## Why get_custom_field is rated Low This tool retrieves or queries a specific custom field from the GoHighLevel CRM using its ID. It performs no modifications, deletions, or external operations. The action is read-only and has no destructive capability. Severity is low because disclosure or misuse of this tool would only allow an attacker to view existing custom field data, not modify or delete it. From the tool's own definition: "Tool name 'get_custom_field' and description 'Get a single custom field by ID' indicate a retrieval operation with no side effects." ## Use case AI agents call get_custom_field 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": { "get_custom_field": {} } } ``` ## Other tools on GoHighLevel MCP Server (63) - `delete_appointment` — Destructive — https://policylayer.com/tools/basicmachines-co-open-ghl-mcp/delete-appointment.md - `delete_contact` — Destructive — https://policylayer.com/tools/basicmachines-co-open-ghl-mcp/delete-contact.md - `delete_contact_note` — Destructive — https://policylayer.com/tools/basicmachines-co-open-ghl-mcp/delete-contact-note.md - `delete_contact_task` — Destructive — https://policylayer.com/tools/basicmachines-co-open-ghl-mcp/delete-contact-task.md - `delete_custom_field` — Destructive — https://policylayer.com/tools/basicmachines-co-open-ghl-mcp/delete-custom-field.md - `delete_custom_value` — Destructive — https://policylayer.com/tools/basicmachines-co-open-ghl-mcp/delete-custom-value.md - `delete_opportunity` — Destructive — https://policylayer.com/tools/basicmachines-co-open-ghl-mcp/delete-opportunity.md - `delete_user` — Destructive — https://policylayer.com/tools/basicmachines-co-open-ghl-mcp/delete-user.md - `remove_contact_from_workflow` — Destructive — https://policylayer.com/tools/basicmachines-co-open-ghl-mcp/remove-contact-from-workflow.md - `ghl_request` — Execute — https://policylayer.com/tools/basicmachines-co-open-ghl-mcp/ghl-request.md - `debug_config` — Read — https://policylayer.com/tools/basicmachines-co-open-ghl-mcp/debug-config.md - `get_all_form_submissions` — Read — https://policylayer.com/tools/basicmachines-co-open-ghl-mcp/get-all-form-submissions.md - `get_appointment` — Read — https://policylayer.com/tools/basicmachines-co-open-ghl-mcp/get-appointment.md - `get_appointments` — Read — https://policylayer.com/tools/basicmachines-co-open-ghl-mcp/get-appointments.md - `get_calendar` — Read — https://policylayer.com/tools/basicmachines-co-open-ghl-mcp/get-calendar.md - `get_calendars` — Read — https://policylayer.com/tools/basicmachines-co-open-ghl-mcp/get-calendars.md - `get_contact` — Read — https://policylayer.com/tools/basicmachines-co-open-ghl-mcp/get-contact.md - `get_contact_note` — Read — https://policylayer.com/tools/basicmachines-co-open-ghl-mcp/get-contact-note.md - `get_contact_notes` — Read — https://policylayer.com/tools/basicmachines-co-open-ghl-mcp/get-contact-notes.md - `get_contact_task` — Read — https://policylayer.com/tools/basicmachines-co-open-ghl-mcp/get-contact-task.md - `get_contact_tasks` — Read — https://policylayer.com/tools/basicmachines-co-open-ghl-mcp/get-contact-tasks.md - `get_conversation` — Read — https://policylayer.com/tools/basicmachines-co-open-ghl-mcp/get-conversation.md - `get_conversations` — Read — https://policylayer.com/tools/basicmachines-co-open-ghl-mcp/get-conversations.md - `get_custom_fields` — Read — https://policylayer.com/tools/basicmachines-co-open-ghl-mcp/get-custom-fields.md - `get_custom_value` — Read — https://policylayer.com/tools/basicmachines-co-open-ghl-mcp/get-custom-value.md - `get_custom_values` — Read — https://policylayer.com/tools/basicmachines-co-open-ghl-mcp/get-custom-values.md - `get_forms` — Read — https://policylayer.com/tools/basicmachines-co-open-ghl-mcp/get-forms.md - `get_free_slots` — Read — https://policylayer.com/tools/basicmachines-co-open-ghl-mcp/get-free-slots.md - `get_messages` — Read — https://policylayer.com/tools/basicmachines-co-open-ghl-mcp/get-messages.md - `get_opportunities` — Read — https://policylayer.com/tools/basicmachines-co-open-ghl-mcp/get-opportunities.md - …and 33 more: https://policylayer.com/tools/basicmachines-co-open-ghl-mcp.md ## For agents This record is a snapshot.
