"Canonical" matching MCP servers:

Enables publishing markdown blog posts directly to Dev.to as drafts or live articles through a single MCP tool, with support for tags, series, canonical URL, and cover image.

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.

Enables canonical social content packages to be ingested, adapted into platform-native variants with classified diffs, and bound to hash-verified owner approvals. It also evaluates engagement policy, tracks accounts and kill switches, and records hash-chained receipts without performing platform actions or network calls.

Enables AI assistants to publish posts to Medium with support for drafts, tags, canonical URLs, and follower notifications. Supports various publishing statuses and SEO optimization features.

Enables an AI assistant or any MCP client to publish, cross-post, schedule, and preview markdown stories on Medium, DEV, and other pluggable platforms, while keeping credentials out of the chat and adding a canonical link back to the author's own blog.
