Perplexity

Windsurf autonomous subscriber sync

Connect this MCP Server, and Cascade reads your project context to automatically build integration logic. If you need a script to pull your top buyers and sync them to SMS lists, the agent handles the entire sequence. It figures out the exact API calls without needing step-by-step instructions. The agent uses `list_subscribers` to check existing records, then runs `create_subscriber` or `update_subscriber` based on what it finds. You define the target audience. Cascade writes the code, executes the sync, and shows you the final result right in your editor.

Audit campaign performance instantly

Stop switching tabs to check how yesterday's text blast performed. You can ask your agent to pull the metrics while you stay in your codebase. It grabs the raw data and formats it exactly how you need it for your internal dashboards. Behind the scenes, Cascade calls `list_campaigns` to find active sends and `get_campaign` to pull the specific conversion numbers. If you want to compare those against your `list_automations` data, the agent chains those requests together and outputs a clean summary.

Manage webhook infrastructure

Setting up event listeners for SMS replies usually means digging through API docs and manually registering endpoints. This integration gives your IDE direct access to your account's event routing. You just tell the agent which events you want to track. Cascade will inspect your local endpoint structure, then fire `create_webhook` to register it. If an old route breaks or gets deprecated, the agent runs `list_webhooks` to find the stale entry and `delete_webhook` to clean it up.
