# create_list Create a new subscriber list Agent View of the PolicyLayer registry record for `create_list`. HTML page: https://policylayer.com/tools/io-github-polnikale-sequenzy-mcp/create-list ## Facts - Tool: `create_list` - Server: Sequenzy Mcp (`Sequenzy/mcp`) — https://policylayer.com/tools/io-github-polnikale-sequenzy-mcp.md - Homepage: https://github.com/Sequenzy/mcp - Risk category: Write (Medium risk) - Registry record: grade D, identity unverified - Server auth posture: gated - Server CORS policy: *, * - 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": "create_list", "arguments": {} } } ``` ## Why create_list is rated Medium Creating a new list is a write operation that adds a new entity to the system. It is reversible (the list can be deleted), so it does not qualify as Destructive. The blast radius is medium because miscreation of lists could disrupt email marketing workflows, but the impact is limited to data organization rather than financial transactions or irreversible data loss. This fits squarely in the Write category. From the tool's own definition: "Tool name is 'create_list' and description states 'Create a new subscriber list' — this creates a new data structure within the email marketing system." ## Use case AI agents use create_list to create or update resources in Sequenzy Mcp, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Sequenzy Mcp environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Sequenzy Mcp: ```json { "version": "1", "default": "deny", "tools": { "create_list": { "limits": [ { "counter": "create_list_rate", "window": "minute", "max": 30, "scope": "grant" } ] } } } ``` ## Other tools on Sequenzy Mcp (221) - `cancel_campaign` — Destructive — https://policylayer.com/tools/io-github-polnikale-sequenzy-mcp/cancel-campaign.md - `cancel_sequence_enrollments` — Destructive — https://policylayer.com/tools/io-github-polnikale-sequenzy-mcp/cancel-sequence-enrollments.md - `cancel_team_invitation` — Destructive — https://policylayer.com/tools/io-github-polnikale-sequenzy-mcp/cancel-team-invitation.md - `delete_ab_test` — Destructive — https://policylayer.com/tools/io-github-polnikale-sequenzy-mcp/delete-ab-test.md - `delete_ab_test_variant` — Destructive — https://policylayer.com/tools/io-github-polnikale-sequenzy-mcp/delete-ab-test-variant.md - `delete_api_key` — Destructive — https://policylayer.com/tools/io-github-polnikale-sequenzy-mcp/delete-api-key.md - `delete_audience_sync` — Destructive — https://policylayer.com/tools/io-github-polnikale-sequenzy-mcp/delete-audience-sync.md - `delete_campaign` — Destructive — https://policylayer.com/tools/io-github-polnikale-sequenzy-mcp/delete-campaign.md - `delete_campaign_goal` — Destructive — https://policylayer.com/tools/io-github-polnikale-sequenzy-mcp/delete-campaign-goal.md - `delete_email_component` — Destructive — https://policylayer.com/tools/io-github-polnikale-sequenzy-mcp/delete-email-component.md - `delete_landing_page` — Destructive — https://policylayer.com/tools/io-github-polnikale-sequenzy-mcp/delete-landing-page.md - `delete_list` — Destructive — https://policylayer.com/tools/io-github-polnikale-sequenzy-mcp/delete-list.md - `delete_popup` — Destructive — https://policylayer.com/tools/io-github-polnikale-sequenzy-mcp/delete-popup.md - `delete_product` — Destructive — https://policylayer.com/tools/io-github-polnikale-sequenzy-mcp/delete-product.md - `delete_segment` — Destructive — https://policylayer.com/tools/io-github-polnikale-sequenzy-mcp/delete-segment.md - `delete_sequence` — Destructive — https://policylayer.com/tools/io-github-polnikale-sequenzy-mcp/delete-sequence.md - `delete_sequence_goal` — Destructive — https://policylayer.com/tools/io-github-polnikale-sequenzy-mcp/delete-sequence-goal.md - `delete_subscriber_note` — Destructive — https://policylayer.com/tools/io-github-polnikale-sequenzy-mcp/delete-subscriber-note.md - `delete_tag` — Destructive — https://policylayer.com/tools/io-github-polnikale-sequenzy-mcp/delete-tag.md - `delete_template` — Destructive — https://policylayer.com/tools/io-github-polnikale-sequenzy-mcp/delete-template.md - `delete_transactional_email` — Destructive — https://policylayer.com/tools/io-github-polnikale-sequenzy-mcp/delete-transactional-email.md - `delete_web_tracking_key` — Destructive — https://policylayer.com/tools/io-github-polnikale-sequenzy-mcp/delete-web-tracking-key.md - `delete_webhook` — Destructive — https://policylayer.com/tools/io-github-polnikale-sequenzy-mcp/delete-webhook.md - `remove_landing_page_domain` — Destructive — https://policylayer.com/tools/io-github-polnikale-sequenzy-mcp/remove-landing-page-domain.md - `remove_product_file` — Destructive — https://policylayer.com/tools/io-github-polnikale-sequenzy-mcp/remove-product-file.md - `remove_subscriber` — Destructive — https://policylayer.com/tools/io-github-polnikale-sequenzy-mcp/remove-subscriber.md - `remove_subscribers_from_list` — Destructive — https://policylayer.com/tools/io-github-polnikale-sequenzy-mcp/remove-subscribers-from-list.md - `revoke_api_key` — Destructive — https://policylayer.com/tools/io-github-polnikale-sequenzy-mcp/revoke-api-key.md - `realign_sequence_enrollments` — Execute — https://policylayer.com/tools/io-github-polnikale-sequenzy-mcp/realign-sequence-enrollments.md - `replay_webhook_delivery` — Execute — https://policylayer.com/tools/io-github-polnikale-sequenzy-mcp/replay-webhook-delivery.md - …and 191 more: https://policylayer.com/tools/io-github-polnikale-sequenzy-mcp.md ## For agents This record is a snapshot.
