# generate_subject_lines Generate A/B test subject line variants Agent View of the PolicyLayer registry record for `generate_subject_lines`. HTML page: https://policylayer.com/tools/io-github-polnikale-sequenzy-mcp/generate-subject-lines ## Facts - Tool: `generate_subject_lines` - 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": "generate_subject_lines", "arguments": {} } } ``` ## Why generate_subject_lines is rated Medium This tool generates and creates subject line variants, which modifies data by adding new test variations to the system. It does not delete data (not Destructive), execute arbitrary code (not Execute), move money (not Financial), or retrieve existing data without modification (not Read). The action is reversible — variants can be removed or replaced. From the tool's own definition: "Tool description states 'Generate A/B test subject line variants' — it creates new subject line variants for testing purposes. The sibling tool 'add_ab_test_variant' confirms this server supports A/B test variant creation as a write operation." ## Use case AI agents use generate_subject_lines 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": { "generate_subject_lines": { "limits": [ { "counter": "generate_subject_lines_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.
