"Mastodon" matching MCP servers:

Checks a social post against a platform's real character limit before it ships — X bills every URL at 23 characters and weights non-Latin script at 2, while Bluesky and Mastodon count grapheme clusters. Covers X, X Premium, Bluesky, LinkedIn, Threads, Mastodon, and Discord, with no credentials and no network access.

Schedule and manage social media posts across 13 platforms (Bluesky, Threads, Instagram, LinkedIn, Mastodon, YouTube, Facebook, Pinterest, Telegram, Nostr, X/Twitter, Discord, Tumblr and more). OAuth 2.0 + PKCE, 10 tools, draft-first workflow for AI agents.

Schedule, manage, generate, and analyze social posts across 11 networks (Instagram, TikTok, X, LinkedIn, YouTube, Facebook, Pinterest, Threads, Bluesky, Mastodon, Telegram) from any AI agent — 13 tools covering scheduling, media upload, AI caption generation, best-times, analytics, listening, and comments.

Enables AI agents to write, schedule, publish, and measure social media posts across LinkedIn, Bluesky, Mastodon, and YouTube, plus manage media and queue slots, through one OAuth URL with no install or API key. It also covers retrying, cancelling, restoring posts and reading analytics, with reversibility safeguards around irreversible publishing.

Cross-publishes a single markdown draft to 5 CMS platforms (dev.to, Hashnode, Ghost, WordPress, Medium) and 4 social networks (Bluesky, Mastodon, LinkedIn, X) from any MCP client, with built-in SEO scoring, schema.org JSON-LD, and canonical URL handling so cross-posts compound search rankings instead of competing.
