# set_file_permissions Set file permissions for specific files Agent View of the PolicyLayer registry record for `set_file_permissions`. HTML page: https://policylayer.com/tools/cbrown35-20i-mcp/set-file-permissions ## Facts - Tool: `set_file_permissions` - Server: 20i MCP Server (`cbrown35/20i-mcp`) — https://policylayer.com/tools/cbrown35-20i-mcp.md - Homepage: https://github.com/Cbrown35/20i-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": "set_file_permissions", "arguments": {} } } ``` ## Why set_file_permissions is rated Medium Setting file permissions modifies file attributes and access controls, which is a reversible write operation. While this does not delete data, incorrect permission changes could impact system security and file accessibility. Severity is high due to potential for privilege escalation or lockout of critical files if misused by an AI agent without proper safeguards. From the tool's own definition: "Tool sets file permissions for specific files; modifies access control attributes on files. The description explicitly states 'Set file permissions' indicating a write operation that changes file metadata." ## Use case AI agents use set_file_permissions to create or update resources in 20i MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your 20i MCP Server environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches 20i MCP Server: ```json { "version": "1", "default": "deny", "tools": { "set_file_permissions": { "limits": [ { "counter": "set_file_permissions_rate", "window": "minute", "max": 30, "scope": "grant" } ] } } } ``` ## Other tools on 20i MCP Server (301) - `deactivate_package` — Destructive — https://policylayer.com/tools/cbrown35-20i-mcp/deactivate-package.md - `deactivate_vps` — Destructive — https://policylayer.com/tools/cbrown35-20i-mcp/deactivate-vps.md - `delete_application` — Destructive — https://policylayer.com/tools/cbrown35-20i-mcp/delete-application.md - `delete_cdn_security_headers` — Destructive — https://policylayer.com/tools/cbrown35-20i-mcp/delete-cdn-security-headers.md - `delete_easy_builder_instance` — Destructive — https://policylayer.com/tools/cbrown35-20i-mcp/delete-easy-builder-instance.md - `delete_hosting_package` — Destructive — https://policylayer.com/tools/cbrown35-20i-mcp/delete-hosting-package.md - `delete_mssql_database` — Destructive — https://policylayer.com/tools/cbrown35-20i-mcp/delete-mssql-database.md - `delete_package` — Destructive — https://policylayer.com/tools/cbrown35-20i-mcp/delete-package.md - `manage_directories` — Destructive — https://policylayer.com/tools/cbrown35-20i-mcp/manage-directories.md - `manage_wordpress_plugin` — Destructive — https://policylayer.com/tools/cbrown35-20i-mcp/manage-wordpress-plugin.md - `purge_cdn_cache` — Destructive — https://policylayer.com/tools/cbrown35-20i-mcp/purge-cdn-cache.md - `rebuild_vps` — Destructive — https://policylayer.com/tools/cbrown35-20i-mcp/rebuild-vps.md - `reinstall_software` — Destructive — https://policylayer.com/tools/cbrown35-20i-mcp/reinstall-software.md - `reinstall_wordpress` — Destructive — https://policylayer.com/tools/cbrown35-20i-mcp/reinstall-wordpress.md - `remove_country_block` — Destructive — https://policylayer.com/tools/cbrown35-20i-mcp/remove-country-block.md - `remove_ip_block` — Destructive — https://policylayer.com/tools/cbrown35-20i-mcp/remove-ip-block.md - `remove_mssql_user` — Destructive — https://policylayer.com/tools/cbrown35-20i-mcp/remove-mssql-user.md - `remove_ssl_certificates` — Destructive — https://policylayer.com/tools/cbrown35-20i-mcp/remove-ssl-certificates.md - `remove_stack_user_from_package` — Destructive — https://policylayer.com/tools/cbrown35-20i-mcp/remove-stack-user-from-package.md - `remove_subdomain` — Destructive — https://policylayer.com/tools/cbrown35-20i-mcp/remove-subdomain.md - `reset_managed_vps_profile` — Destructive — https://policylayer.com/tools/cbrown35-20i-mcp/reset-managed-vps-profile.md - `restore_ftp_backup` — Destructive — https://policylayer.com/tools/cbrown35-20i-mcp/restore-ftp-backup.md - `restore_snapshot` — Destructive — https://policylayer.com/tools/cbrown35-20i-mcp/restore-snapshot.md - `shutdown_vps` — Destructive — https://policylayer.com/tools/cbrown35-20i-mcp/shutdown-vps.md - `suspend_package` — Destructive — https://policylayer.com/tools/cbrown35-20i-mcp/suspend-package.md - `activate_vps` — Execute — https://policylayer.com/tools/cbrown35-20i-mcp/activate-vps.md - `change_vps_root_password` — Execute — https://policylayer.com/tools/cbrown35-20i-mcp/change-vps-root-password.md - `clone_wordpress_staging` — Execute — https://policylayer.com/tools/cbrown35-20i-mcp/clone-wordpress-staging.md - `deploy_application` — Execute — https://policylayer.com/tools/cbrown35-20i-mcp/deploy-application.md - `deploy_website_complete` — Execute — https://policylayer.com/tools/cbrown35-20i-mcp/deploy-website-complete.md - …and 271 more: https://policylayer.com/tools/cbrown35-20i-mcp.md ## For agents This record is a snapshot.
