FREQUENTLY ASKED QUESTIONS
What is Postbye?
Postbye is an MCP server (package postbye-mcp) that exposes cancellation letters, mailing addresses, and how-to-cancel guides for 8,600+ companies. It is served from the remote MCP endpoint https://postbye.com/mcp and is aimed at developer-tools and agent workflows that need reliable cancellation data.
How do I install it?
Postbye is a remote MCP server, so installation is configuration rather than a local build: add an MCP server entry that points to https://postbye.com/mcp (the postbye-mcp package) in your client's config file, then restart the client. Ready-made setup snippets are published for Claude, Cursor, and VS Code.
What are the authentication requirements?
The public MCP endpoint is added by URL and does not document mandatory API keys or OAuth scopes for basic use. If your Postbye plan or deployment requires credentials, supply them through your MCP client's header or environment settings and confirm the exact scheme in the Postbye setup documentation.
Which clients are supported?
Postbye documents setup configurations for Claude, Cursor, and VS Code. Because it is a standard remote MCP server, any client that supports URL-based MCP servers over HTTP can connect to https://postbye.com/mcp, subject to that client's transport support.
