# get_custom_fields List all custom fields for a location (optionally filtered by model) Agent View of the PolicyLayer registry record for `get_custom_fields`. HTML page: https://policylayer.com/tools/basicmachines-co-open-ghl-mcp/get-custom-fields ## Facts - Tool: `get_custom_fields` - 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_fields", "arguments": {} } } ``` ## Why get_custom_fields is rated Low This tool queries and returns custom field metadata for a location without creating, modifying, or deleting data. It is a read-only operation that retrieves information. The blast radius of misuse is minimal—an AI agent could retrieve custom field definitions but cannot perform destructive or financial actions with this tool alone. From the tool's own definition: "Tool name 'get_custom_fields' and description 'List all custom fields for a location' indicate a retrieval operation with no data modification or side effects." ## Use case AI agents call get_custom_fields 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_fields": {} } } ``` ## 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_field` — Read — https://policylayer.com/tools/basicmachines-co-open-ghl-mcp/get-custom-field.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.
