Overview Installation

Overview

Postbye is an MCP server that helps you cancel subscriptions by providing real cancellation letters and verified mailing addresses for over 10,000 companies. Instead of hunting down contact information and drafting your own letters, you can query Postbye to get ready-to-use cancellation templates and official addresses, then send them directly.

The server runs as a hosted remote service at https://postbye.com/mcp with no local installation required and no authentication needed. Version v1.2.0 is the latest release. Simply point your MCP client to the endpoint and start using it immediately.

Postbye is listed in the Development category on mcp.site and works with any MCP client including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain Postbye, you're invited to claim this listing to verify your ownership, display the Verified badge, and keep the information up to date.
