Postmark MCP Server

Postmark ships an official, first-party MCP server. It is distributed ONLY as a local-stdio npm package — there is no hosted remote endpoint an MCP client can POST to. Postmark's own landing page (https://postmarkapp.com/lp/mcp) gives a single install path: `npx -y @activecampaign/postmark-mcp` in the client's mcpServers config.

One-click install for Cursor, VS Code, Claude, and 20+ other MCP clients, powered by API Commons MCP Install — visit install.apicommons.org for more information.

About MCP

The Model Context Protocol (MCP) is an open protocol Anthropic introduced for connecting LLM-based agents to external tools and data sources. Providers publish MCP servers that expose their API surface as structured, discoverable tools — an MCP-compatible client (Claude Desktop, Cursor, Cline, Continue, etc.) can connect to the server and call its tools without any per-provider integration code.

Browse every MCP server on the APIs.io network or compare with the broader Agent Skill surfaces of the same providers.
