# update_custom_value Update an existing custom value Agent View of the PolicyLayer registry record for `update_custom_value`. HTML page: https://policylayer.com/tools/basicmachines-co-open-ghl-mcp/update-custom-value ## Facts - Tool: `update_custom_value` - 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: Write (Medium risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Rate-limited ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "update_custom_value", "arguments": {} } } ``` ## Why update_custom_value is rated Medium This tool modifies data reversibly—it updates an existing custom value rather than creating new data or deleting it. Updates can typically be undone by applying a different update, making this a Write operation. Severity is medium because misuse could corrupt or alter CRM data fields that affect business operations, but the blast radius is limited to custom value fields and reversible. From the tool's own definition: "Tool name is 'update_custom_value' with description 'Update an existing custom value'. The verb 'update' indicates modification of existing data in the GoHighLevel CRM system." ## Use case AI agents use update_custom_value to create or update resources in GoHighLevel MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your GoHighLevel MCP Server environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
