BlogCaster - Multi-Platform MCP Publishing Server
Publishing a blog across Hashnode, Dev.to, and WordPress means copying and pasting Markdown three times. BlogCaster is an MCP tool that lets your AI assistant publish to all of them in one command.

The Problem
When you write technical articles with AI assistance (like in Claude Desktop or Cursor), getting the finished post published is still a hassle. You have to open three different browser tabs, paste Markdown, fix formatting quirks, upload headers, and deal with separate API tokens across Hashnode, Dev.to, and WordPress.
How BlogCaster Solves It
BlogCaster connects to your AI assistant using the Model Context Protocol (MCP). Instead of manual copy-pasting, you can just tell your AI: "Publish this article to Hashnode and Dev.to."
The server takes your Markdown, sets the title, handles tags, preserves canonical links, and publishes everything directly through their official APIs.
How It's Built
- Cloudflare Workers: Hosted at the edge so it runs globally with almost zero latency and no server maintenance.
- Durable Objects: Keeps session state and API tokens separate for each user, so credentials never get mixed up.
- Dual Support: Works as a hosted cloud endpoint for remote AI clients and as an installable NPM package for local desktop editors.
What It Means
It turns a tedious 15-minute publishing chore into a single natural-language command inside your editor.
