# update_appointment Update an existing appointment Agent View of the PolicyLayer registry record for `update_appointment`. HTML page: https://policylayer.com/tools/basicmachines-co-open-ghl-mcp/update-appointment ## Facts - Tool: `update_appointment` - 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_appointment", "arguments": {} } } ``` ## Why update_appointment is rated Medium This tool creates or modifies data reversibly. Updating an appointment changes calendar/scheduling data but does not delete it and can be undone by updating again. It falls under the Write category. Severity is medium because misuse could disrupt business operations (e.g., changing critical client meetings) but the impact is limited to one appointment and is reversible. From the tool's own definition: "Tool name is 'update_appointment' and description states 'Update an existing appointment' — this modifies existing data in the CRM calendar system." ## Use case AI agents use update_appointment 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**.
