postcache

Overview

postcache is a Model Context Protocol server that generates public, short-lived media URLs for agents posting to Instagram, Threads and Facebook. It integrates directly into your AI assistant, exposing posting functionality as callable tools that work on your behalf.

The server runs remotely at https://postcache.dev/mcp, so there's nothing to install locally — just point your MCP client at the endpoint and authenticate with your API key. The current release is v1.0.0, available via the vendor at https://postcache.dev/docs.

You'll find postcache listed in the AI & Agents category on mcp.site. It works with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and others. If you maintain postcache, claim this listing to verify ownership and keep the information up to date.
