Perplexity

Claude Code headless subscriber sync

Cron jobs that sync database records to your marketing lists often fail silently. By attaching this integration, you can run an intelligent agent in your terminal that actively checks list health, flags sync errors, and corrects formatting issues on the fly. You can pipe a CSV of new buyers into the CLI. The agent iterates through the list, checking `get_subscriber` for existing profiles. It then fires `create_subscriber` for new numbers and `update_subscriber` for status changes, handling rate limits automatically.

Automate campaign audits in CI/CD

Stop manually checking if your holiday messaging flows are active before a major deployment. You can add a quick terminal command to your deployment pipeline that verifies all required automated responses are running correctly. The agent executes `list_automations` and `list_campaigns` during your build step. If a critical abandoned cart flow is paused, the script halts the deployment and alerts your team via standard output.

Infrastructure as code for webhooks

Managing event endpoints through a web UI leads to configuration drift. This MCP Server gives you a way to script your endpoint registrations so they match your deployed application environments exactly. Run a shell script that tells the agent to audit your routing. It pulls current routes with `list_webhooks`, compares them to your local config, and uses `create_webhook` or `delete_webhook` to force the remote state to match your local architecture.

Common questions about Postscript MCP in Claude Code

Run `claude mcp add --transport http postscript-mcp -- ` in your terminal. Ensure all flags precede the server name. The configuration saves automatically to your ~/.claude.json file.

Yes. You can wrap the CLI command in a standard shell script and schedule it. The agent handles the execution headlessly and pipes the results to your standard logging tools.

The agent reads the response headers. If it hits a limit while processing a large batch of updates, it backs off automatically and retries the operation without crashing your script.

You can connect using stdio, http, or sse transports depending on your network architecture. HTTP is the most common for remote execution environments.

The raw phone numbers, consent records, and campaign metrics never leave your secure environment. This MCP Server processes the payloads locally and sends them straight to the official API endpoints over TLS.
