# trigger_subscriber_events Emit several custom events for one subscriber in order. Events are processed independently and sequentially, so a partial failure can still leave earlier events recorded. Agent View of the PolicyLayer registry record for `trigger_subscriber_events`. HTML page: https://policylayer.com/tools/io-github-polnikale-sequenzy-mcp/trigger-subscriber-events ## Facts - Tool: `trigger_subscriber_events` - Server: Sequenzy Mcp (`Sequenzy/mcp`) — https://policylayer.com/tools/io-github-polnikale-sequenzy-mcp.md - Homepage: https://github.com/Sequenzy/mcp - Risk category: Execute (High 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": "trigger_subscriber_events", "arguments": {} } } ``` ## Why trigger_subscriber_events is rated High This tool triggers custom events for subscribers, which are external operations that execute in sequence. While not destructive (events can theoretically be reversed or logged), it performs state-changing actions in the marketing automation system based on provided arguments. The sequential processing and note that 'partial failure can still leave earlier events recorded' indicates irreversible intermediate states. From the tool's own definition: "Tool description states it will 'Emit several custom events for one subscriber in order' and 'Events are processed independently and sequentially.' The verb 'Emit' combined with processing external events indicates execution of operations with side effects…" ## Use case AI agents invoke trigger_subscriber_events to trigger actions in Sequenzy Mcp. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
