Paubox MCP Server
Paubox ships a first-party Model Context Protocol server exposing 30 tools across the Email API, Forms API and Marketing API. It is offered over two transports: a hosted streamable-HTTP endpoint at https://mcp.paubox.com/mcp and a stdio package invoked with npx. Tool names and descriptions below were read verbatim from the provider's own tool reference at https://docs.paubox.com/mcp-server/tools; the live tools/list manifest is auth-gated, so per-tool inputSchema was NOT captured (see x-evidence).
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.
Work with this as data
Every MCP server here is available over the APIs.io API and to AI agents over MCP.
