Postproxy

Overview

Postproxy is a Model Context Protocol (MCP) server: Publish, schedule, and manage social media posts across major platforms via the Postproxy API. Because it speaks the Model Context Protocol, AI assistants can use Postproxy as a set of callable tools instead of you copy-pasting between apps.

It's a hosted (remote) server — point your client at https://mcp.postproxy.dev/mcp and you're connected, with nothing to install locally. The current release is v1.10.0, published under the MIT license, with source at postproxy/postproxy-mcp on GitHub.

On mcp.site, Postproxy sits in the Marketing category. Any MCP client can use it — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed among them — via the install snippets below.
