Postbolt

whitemarmot/postbolt-mcp

Connects Claude to PostBolt's API for publishing across 13+ social platforms including Twitter, LinkedIn, Instagram, Threads, and TikTok. You get tools to publish immediately or schedule posts, upload media, and manage content with platform-specific overrides. Useful when you want AI to handle social media posting without switching contexts or writing integration code. The server exposes your PostBolt quota and connected accounts as resources, and includes operations to list, update, and cancel scheduled posts. Requires a PostBolt API key and supports custom content per platform, so you can tailor a LinkedIn announcement differently from a tweet in the same request.
