Ask your AI agent "Send a postcard to Jane Doe using campaign ID 'camp_123'." and get the answer without opening a single dashboard. With 11 tools connected to real Poplar data, your agents reason over live information, cross-reference it with other MCP servers, and deliver insights you would spend hours assembling manually.
Works with Claude, ChatGPT, Cursor, and any MCP-compatible client. Powered by the Vinkius - your credentials never touch the AI model, every request is auditable. Connect in under two minutes.

Frequently asked questions about the Poplar MCP Server
How do I get my Poplar Access Token?
Log in to your Poplar account and navigate to the API Settings or Developer section. You will find your Access Token there. Use a Test Token for development and a Production Token for live mailings.
Can I standardize non-US addresses?
No, Poplar's address standardization service is specifically designed for US addresses only. For international mailing, ensure your addresses are pre-formatted correctly.
How can I check if a mailer has been delivered?
Use the get_mailer_status tool with the unique mailer ID. It will return the current status, including production phases and the final USPS delivery confirmation when available.
Is the integration secure for customer addresses?
Absolutely. The integration uses official Poplar Bearer tokens over HTTPS. Your credentials and customer data are encrypted and stored securely within the Vinkius Cloud infrastructure.
