Tools for your AI Agents to operate Poplar

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

01

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.

02

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.

03

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.
