# get_metrics_evidence_sample_data A read tool on the ComplianceCow MCP Server MCP server. Agent View of the PolicyLayer registry record for `get_metrics_evidence_sample_data`. HTML page: https://policylayer.com/tools/compliancecow-cow-mcp/get-metrics-evidence-sample-data ## Facts - Tool: `get_metrics_evidence_sample_data` - 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": "get_metrics_evidence_sample_data", "arguments": {} } } ``` ## Why get_metrics_evidence_sample_data is rated Low The 'get_' prefix unambiguously indicates data retrieval with no side effects. Even though the description is empty (lowering confidence slightly), the naming convention and context of retrieving 'sample data' for metrics and evidence aligns with read operations that query the Compliance Graph. The tool appears designed to fetch auditable evidence, not modify or execute actions. From the tool's own definition: "Tool name 'get_metrics_evidence_sample_data' indicates a retrieval operation that fetches sample data related to metrics and evidence. The 'get_' prefix strongly suggests a read-only query operation." ## Use case AI agents call get_metrics_evidence_sample_data 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": { "get_metrics_evidence_sample_data": {} } } ``` ## 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.
