# list_workflow_predefined_variables A read tool on the ComplianceCow MCP Server MCP server. Agent View of the PolicyLayer registry record for `list_workflow_predefined_variables`. HTML page: https://policylayer.com/tools/compliancecow-cow-mcp/list-workflow-predefined-variables ## Facts - Tool: `list_workflow_predefined_variables` - Server: ComplianceCow MCP Server (`compliancecow/cow-mcp`) — https://policylayer.com/tools/compliancecow-cow-mcp.md - Homepage: https://github.com/ComplianceCow/cow-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": "list_workflow_predefined_variables", "arguments": {} } } ``` ## Why list_workflow_predefined_variables is rated Low This tool retrieves or queries predefined variables used in workflows, returning reference data without modifying system state. Even though the description is empty, the naming convention and context of a compliance platform where workflow variables are configuration metadata indicate a read-only operation. Blast radius is minimal: obtaining variable definitions poses no direct risk to compliance data integrity. From the tool's own definition: "The tool name 'list_workflow_predefined_variables' indicates a listing/retrieval operation. The absence of mutation verbs (create, update, delete, modify) and the 'list_' prefix—consistent with other Read operations on this server like…" ## Use case AI agents call list_workflow_predefined_variables to retrieve information from ComplianceCow 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 ComplianceCow MCP Server: ```json { "version": "1", "default": "deny", "tools": { "list_workflow_predefined_variables": {} } } ``` ## Other tools on ComplianceCow MCP Server (208) - `delete_asset_schedule` — Destructive — https://policylayer.com/tools/compliancecow-cow-mcp/delete-asset-schedule.md - `create_sql_query_evidence` — Execute — https://policylayer.com/tools/compliancecow-cow-mcp/create-sql-query-evidence.md - `execute_action` — Execute — https://policylayer.com/tools/compliancecow-cow-mcp/execute-action.md - `execute_cypher_query` — Execute — https://policylayer.com/tools/compliancecow-cow-mcp/execute-cypher-query.md - `execute_rule` — Execute — https://policylayer.com/tools/compliancecow-cow-mcp/execute-rule.md - `execute_shell_command` — Execute — https://policylayer.com/tools/compliancecow-cow-mcp/execute-shell-command.md - `execute_task` — Execute — https://policylayer.com/tools/compliancecow-cow-mcp/execute-task.md - `prepare_applications_for_execution` — Execute — https://policylayer.com/tools/compliancecow-cow-mcp/prepare-applications-for-execution.md - `run_metrics_assessment` — Execute — https://policylayer.com/tools/compliancecow-cow-mcp/run-metrics-assessment.md - `schedule_asset_execution` — Execute — https://policylayer.com/tools/compliancecow-cow-mcp/schedule-asset-execution.md - `trigger_workflow` — Execute — https://policylayer.com/tools/compliancecow-cow-mcp/trigger-workflow.md - `validate_sql_query` — Execute — https://policylayer.com/tools/compliancecow-cow-mcp/validate-sql-query.md - `validate_sql_query_and_cel` — Execute — https://policylayer.com/tools/compliancecow-cow-mcp/validate-sql-query-and-cel.md - `collect_parameter_input` — Other — https://policylayer.com/tools/compliancecow-cow-mcp/collect-parameter-input.md - `confirm_parameter_input` — Other — https://policylayer.com/tools/compliancecow-cow-mcp/confirm-parameter-input.md - `confirm_template_input` — Other — https://policylayer.com/tools/compliancecow-cow-mcp/confirm-template-input.md - `create_metric_sql_query_evidence` — Other — https://policylayer.com/tools/compliancecow-cow-mcp/create-metric-sql-query-evidence.md - `create_workflow_custom_event` — Other — https://policylayer.com/tools/compliancecow-cow-mcp/create-workflow-custom-event.md - `generate_design_notes_preview` — Other — https://policylayer.com/tools/compliancecow-cow-mcp/generate-design-notes-preview.md - `generate_rule_readme_preview` — Other — https://policylayer.com/tools/compliancecow-cow-mcp/generate-rule-readme-preview.md - `modify_workflow` — Other — https://policylayer.com/tools/compliancecow-cow-mcp/modify-workflow.md - `publish_application` — Other — https://policylayer.com/tools/compliancecow-cow-mcp/publish-application.md - `audit_fetch_assessment_run_details` — Read — https://policylayer.com/tools/compliancecow-cow-mcp/audit-fetch-assessment-run-details.md - `audit_fetch_assessment_run_leaf_control_evidence` — Read — https://policylayer.com/tools/compliancecow-cow-mcp/audit-fetch-assessment-run-leaf-control-evidence.md - `audit_fetch_assessment_runs` — Read — https://policylayer.com/tools/compliancecow-cow-mcp/audit-fetch-assessment-runs.md - `audit_fetch_evidence_records` — Read — https://policylayer.com/tools/compliancecow-cow-mcp/audit-fetch-evidence-records.md - `audit_get_uses_by_ids` — Read — https://policylayer.com/tools/compliancecow-cow-mcp/audit-get-uses-by-ids.md - `audit_list_all_assessment_categories` — Read — https://policylayer.com/tools/compliancecow-cow-mcp/audit-list-all-assessment-categories.md - `audit_list_all_assessments` — Read — https://policylayer.com/tools/compliancecow-cow-mcp/audit-list-all-assessments.md - `audit_list_assessment_control_configs` — Read — https://policylayer.com/tools/compliancecow-cow-mcp/audit-list-assessment-control-configs.md - …and 178 more: https://policylayer.com/tools/compliancecow-cow-mcp.md ## For agents This record is a snapshot.
