# update_safe A write tool on the CyberArk Privilege Cloud MCP Server MCP server. Agent View of the PolicyLayer registry record for `update_safe`. HTML page: https://policylayer.com/tools/aaearon-mcp-privilege-cloud/update-safe ## Facts - Tool: `update_safe` - Server: CyberArk Privilege Cloud MCP Server (`aaearon/mcp-privilege-cloud`) — https://policylayer.com/tools/aaearon-mcp-privilege-cloud.md - Homepage: https://github.com/aaearon/mcp-privilege-cloud - 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_safe", "arguments": {} } } ``` ## Why update_safe is rated Medium The tool modifies safe configurations (a core vault/container concept in CyberArk) but does not delete them (which would be Destructive). Safe updates are reversible changes to access control, policies, or membership. Severity is high because misconfigured safes can grant or revoke access to sensitive privileged accounts. From the tool's own definition: "Tool name 'update_safe' from CyberArk Privilege Cloud MCP Server, which manages privileged access and safe management. The 'update_' prefix indicates modification of safe configurations or properties." ## Use case AI agents use update_safe to create or update resources in CyberArk Privilege Cloud MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your CyberArk Privilege Cloud MCP Server environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches CyberArk Privilege Cloud MCP Server: ```json { "version": "1", "default": "deny", "tools": { "update_safe": { "limits": [ { "counter": "update_safe_rate", "window": "minute", "max": 30, "scope": "grant" } ] } } } ``` ## Other tools on CyberArk Privilege Cloud MCP Server (52) - `deactivate_target_platform` — Destructive — https://policylayer.com/tools/aaearon-mcp-privilege-cloud/deactivate-target-platform.md - `delete_account` — Destructive — https://policylayer.com/tools/aaearon-mcp-privilege-cloud/delete-account.md - `delete_application` — Destructive — https://policylayer.com/tools/aaearon-mcp-privilege-cloud/delete-application.md - `delete_application_auth_method` — Destructive — https://policylayer.com/tools/aaearon-mcp-privilege-cloud/delete-application-auth-method.md - `delete_safe` — Destructive — https://policylayer.com/tools/aaearon-mcp-privilege-cloud/delete-safe.md - `delete_target_platform` — Destructive — https://policylayer.com/tools/aaearon-mcp-privilege-cloud/delete-target-platform.md - `remove_safe_member` — Destructive — https://policylayer.com/tools/aaearon-mcp-privilege-cloud/remove-safe-member.md - `import_platform_package` — Execute — https://policylayer.com/tools/aaearon-mcp-privilege-cloud/import-platform-package.md - `reconcile_account_password` — Execute — https://policylayer.com/tools/aaearon-mcp-privilege-cloud/reconcile-account-password.md - `verify_account_password` — Execute — https://policylayer.com/tools/aaearon-mcp-privilege-cloud/verify-account-password.md - `export_platform` — Other — https://policylayer.com/tools/aaearon-mcp-privilege-cloud/export-platform.md - `analyze_account_distribution` — Read — https://policylayer.com/tools/aaearon-mcp-privilege-cloud/analyze-account-distribution.md - `count_accounts_by_criteria` — Read — https://policylayer.com/tools/aaearon-mcp-privilege-cloud/count-accounts-by-criteria.md - `count_sessions` — Read — https://policylayer.com/tools/aaearon-mcp-privilege-cloud/count-sessions.md - `filter_accounts_by_environment` — Read — https://policylayer.com/tools/aaearon-mcp-privilege-cloud/filter-accounts-by-environment.md - `filter_accounts_by_management_status` — Read — https://policylayer.com/tools/aaearon-mcp-privilege-cloud/filter-accounts-by-management-status.md - `filter_accounts_by_platform_group` — Read — https://policylayer.com/tools/aaearon-mcp-privilege-cloud/filter-accounts-by-platform-group.md - `get_account_details` — Read — https://policylayer.com/tools/aaearon-mcp-privilege-cloud/get-account-details.md - `get_application_auth_method_details` — Read — https://policylayer.com/tools/aaearon-mcp-privilege-cloud/get-application-auth-method-details.md - `get_application_details` — Read — https://policylayer.com/tools/aaearon-mcp-privilege-cloud/get-application-details.md - `get_applications_stats` — Read — https://policylayer.com/tools/aaearon-mcp-privilege-cloud/get-applications-stats.md - `get_platform_details` — Read — https://policylayer.com/tools/aaearon-mcp-privilege-cloud/get-platform-details.md - `get_platform_statistics` — Read — https://policylayer.com/tools/aaearon-mcp-privilege-cloud/get-platform-statistics.md - `get_safe_details` — Read — https://policylayer.com/tools/aaearon-mcp-privilege-cloud/get-safe-details.md - `get_safe_member_details` — Read — https://policylayer.com/tools/aaearon-mcp-privilege-cloud/get-safe-member-details.md - `get_session_details` — Read — https://policylayer.com/tools/aaearon-mcp-privilege-cloud/get-session-details.md - `get_session_statistics` — Read — https://policylayer.com/tools/aaearon-mcp-privilege-cloud/get-session-statistics.md - `get_target_platform_statistics` — Read — https://policylayer.com/tools/aaearon-mcp-privilege-cloud/get-target-platform-statistics.md - `group_accounts_by_platform` — Read — https://policylayer.com/tools/aaearon-mcp-privilege-cloud/group-accounts-by-platform.md - `group_accounts_by_safe` — Read — https://policylayer.com/tools/aaearon-mcp-privilege-cloud/group-accounts-by-safe.md - …and 22 more: https://policylayer.com/tools/aaearon-mcp-privilege-cloud.md ## For agents This record is a snapshot.
