# clickup_validate_webhook_signature Validate the HMAC signature of a webhook payload to ensure authenticity. Agent View of the PolicyLayer registry record for `clickup_validate_webhook_signature`. HTML page: https://policylayer.com/tools/chykalophia-clickup-mcp-server-enhanced/clickup-validate-webhook-signature ## Facts - Tool: `clickup_validate_webhook_signature` - Server: ClickUp MCP Server - Enhanced (`chykalophia/clickup-mcp-server---enhanced`) — https://policylayer.com/tools/chykalophia-clickup-mcp-server-enhanced.md - Homepage: https://github.com/Chykalophia/ClickUp-MCP-Server---Enhanced - 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": "clickup_validate_webhook_signature", "arguments": {} } } ``` ## Why clickup_validate_webhook_signature is rated Low This tool performs authentication verification on webhook payloads. It reads and validates data (the HMAC signature) to confirm authenticity, but produces no side effects, creates no resources, deletes nothing, and executes no external operations. It is a security check operation that retrieves/validates information. No data is modified, no commands are executed, and no financial or destructive operations occur. From the tool's own definition: "Tool name and description indicate validation/verification: 'Validate the HMAC signature of a webhook payload to ensure authenticity.' This is a cryptographic verification operation that checks the authenticity of incoming data without modifying, deleting, or…" ## Use case AI agents call clickup_validate_webhook_signature to retrieve information from ClickUp MCP Server - Enhanced 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 ClickUp MCP Server - Enhanced: ```json { "version": "1", "default": "deny", "tools": { "clickup_validate_webhook_signature": {} } } ``` ## Other tools on ClickUp MCP Server - Enhanced (201) - `clickup_bulk_delete_tasks` — Destructive — https://policylayer.com/tools/chykalophia-clickup-mcp-server-enhanced/clickup-bulk-delete-tasks.md - `clickup_delete_attachment` — Destructive — https://policylayer.com/tools/chykalophia-clickup-mcp-server-enhanced/clickup-delete-attachment.md - `clickup_delete_chat_message` — Destructive — https://policylayer.com/tools/chykalophia-clickup-mcp-server-enhanced/clickup-delete-chat-message.md - `clickup_delete_chat_message_reaction` — Destructive — https://policylayer.com/tools/chykalophia-clickup-mcp-server-enhanced/clickup-delete-chat-message-reaction.md - `clickup_delete_checklist` — Destructive — https://policylayer.com/tools/chykalophia-clickup-mcp-server-enhanced/clickup-delete-checklist.md - `clickup_delete_checklist_item` — Destructive — https://policylayer.com/tools/chykalophia-clickup-mcp-server-enhanced/clickup-delete-checklist-item.md - `clickup_delete_comment` — Destructive — https://policylayer.com/tools/chykalophia-clickup-mcp-server-enhanced/clickup-delete-comment.md - `clickup_delete_custom_field` — Destructive — https://policylayer.com/tools/chykalophia-clickup-mcp-server-enhanced/clickup-delete-custom-field.md - `clickup_delete_dependency` — Destructive — https://policylayer.com/tools/chykalophia-clickup-mcp-server-enhanced/clickup-delete-dependency.md - `clickup_delete_doc` — Destructive — https://policylayer.com/tools/chykalophia-clickup-mcp-server-enhanced/clickup-delete-doc.md - `clickup_delete_doc_page` — Destructive — https://policylayer.com/tools/chykalophia-clickup-mcp-server-enhanced/clickup-delete-doc-page.md - `clickup_delete_folder` — Destructive — https://policylayer.com/tools/chykalophia-clickup-mcp-server-enhanced/clickup-delete-folder.md - `clickup_delete_goal` — Destructive — https://policylayer.com/tools/chykalophia-clickup-mcp-server-enhanced/clickup-delete-goal.md - `clickup_delete_goal_target` — Destructive — https://policylayer.com/tools/chykalophia-clickup-mcp-server-enhanced/clickup-delete-goal-target.md - `clickup_delete_list` — Destructive — https://policylayer.com/tools/chykalophia-clickup-mcp-server-enhanced/clickup-delete-list.md - `clickup_delete_subtask` — Destructive — https://policylayer.com/tools/chykalophia-clickup-mcp-server-enhanced/clickup-delete-subtask.md - `clickup_delete_task` — Destructive — https://policylayer.com/tools/chykalophia-clickup-mcp-server-enhanced/clickup-delete-task.md - `clickup_delete_time_entry` — Destructive — https://policylayer.com/tools/chykalophia-clickup-mcp-server-enhanced/clickup-delete-time-entry.md - `clickup_delete_view` — Destructive — https://policylayer.com/tools/chykalophia-clickup-mcp-server-enhanced/clickup-delete-view.md - `clickup_delete_webhook` — Destructive — https://policylayer.com/tools/chykalophia-clickup-mcp-server-enhanced/clickup-delete-webhook.md - `clickup_merge_tasks` — Destructive — https://policylayer.com/tools/chykalophia-clickup-mcp-server-enhanced/clickup-merge-tasks.md - `clickup_remove_chat_channel_member` — Destructive — https://policylayer.com/tools/chykalophia-clickup-mcp-server-enhanced/clickup-remove-chat-channel-member.md - `clickup_add_processing_rule` — Execute — https://policylayer.com/tools/chykalophia-clickup-mcp-server-enhanced/clickup-add-processing-rule.md - `clickup_bulk_attachment_operations` — Execute — https://policylayer.com/tools/chykalophia-clickup-mcp-server-enhanced/clickup-bulk-attachment-operations.md - `clickup_ping_webhook` — Execute — https://policylayer.com/tools/chykalophia-clickup-mcp-server-enhanced/clickup-ping-webhook.md - `clickup_process_webhook` — Execute — https://policylayer.com/tools/chykalophia-clickup-mcp-server-enhanced/clickup-process-webhook.md - `clickup_resolve_dependency_conflicts` — Execute — https://policylayer.com/tools/chykalophia-clickup-mcp-server-enhanced/clickup-resolve-dependency-conflicts.md - `clickup_retry_webhook_events` — Execute — https://policylayer.com/tools/chykalophia-clickup-mcp-server-enhanced/clickup-retry-webhook-events.md - `clickup_start_realtime_engine` — Execute — https://policylayer.com/tools/chykalophia-clickup-mcp-server-enhanced/clickup-start-realtime-engine.md - `clickup_start_timer` — Execute — https://policylayer.com/tools/chykalophia-clickup-mcp-server-enhanced/clickup-start-timer.md - …and 171 more: https://policylayer.com/tools/chykalophia-clickup-mcp-server-enhanced.md ## For agents This record is a snapshot.
