# add_country_block Add a single country to the block list Agent View of the PolicyLayer registry record for `add_country_block`. HTML page: https://policylayer.com/tools/cbrown35-20i-mcp/add-country-block ## Facts - Tool: `add_country_block` - 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": "add_country_block", "arguments": {} } } ``` ## Why add_country_block is rated Medium This tool creates or modifies access control rules by adding countries to a blocklist, which is a Write operation (reversible configuration change). Severity is medium because misconfiguration could block legitimate traffic or be used to deny service, but the effect is limited to access control and can be undone. From the tool's own definition: "Tool name 'add_country_block' and description 'Add a single country to the block list' indicate creation/modification of a firewall or access control rule. This modifies hosting configuration state but is reversible (the block can be removed)." ## Use case AI agents use add_country_block 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": { "add_country_block": { "limits": [ { "counter": "add_country_block_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.
