Frequently asked questions

What is the Postmark MCP server?

The Postmark MCP server is an Communication Model Context Protocol server that lets Claude Code, Cursor, Windsurf, VS Code with Copilot, and other MCP-compatible AI agents send transactional emails and inspect delivery logs through Postmark from AI agents. It exposes Postmark's capabilities as tools the AI can call directly from your editor or CLI.

How do I install Postmark MCP with Claude Code?

The fastest way is the MCPizy CLI: run `mcpizy install postmark` and MCPizy will add the server to your `.claude.json` automatically. You can also install it manually by adding an entry under `mcpServers` in `.claude.json` with the command `npx -y @postmark/mcp-server` and restarting Claude Code.

Is Postmark MCP free?

Yes. The Postmark MCP server is free and open source (see the GitHub repository linked on this page). You may still need a Postmark account or API key to connect the server to the underlying service, but the MCP layer itself has no MCPizy subscription cost.

Does Postmark MCP work with Cursor and Windsurf?

Yes. Any MCP-compatible client works — including Claude Code, Claude Desktop, Cursor (via `.cursor/mcp.json`), Windsurf, VS Code with Copilot Chat, and custom agents built on the MCP SDK. The same install command targets all of them; only the config file path differs.
