Perplexity

Manage newsletters from the command line via MCP Server

The `list_newsletters` tool displays your active newsletter feeds directly in your terminal window. Claude Code uses this to verify your account configuration before running any automation scripts or bulk operations. You can also use `get_account_info` to quickly check your profile settings and API status. This lets you confirm your connection is active without leaving your shell session.

Script automated drafts using Claude Code

The `create_email` tool generates new newsletter drafts directly from your terminal output. Claude Code can pipe local build logs, release notes, or git diffs straight into a new draft. If you want to review what was sent previously, `list_emails` pulls your recent campaign history. Claude Code displays this history in your terminal so you can maintain consistent formatting across drafts using this MCP tool.

Audit your subscriber list from the terminal

The `list_subscribers` tool outputs your entire audience list directly to your console. Claude Code can search, filter, and inspect subscriber records using standard terminal pipes. By calling `get_subscriber` on specific profiles, you can check their status and tags. This allows you to debug sign-up flows or list hygiene issues during your development workflows.
