🚀 BlogCaster MCP — Your Blog Ecosystem, One MCP Server

Cloud-hosted MCP server that lets you publish, list, and delete posts across multiple blogging platforms from any MCP-enabled client (Claude Desktop, Cursor/Cline, etc.). No local installs — just point your client at the URL.

Architecture: Secure Session-Based Storage
Tokens are stored encrypted in dedicated, ephemeral Durable Objects. Each chat session gets a unique storage box.

📦 Installation

Option 1: NPM Package (Recommended)

Install via NPM for local stdio transport:

npm install -g blogcaster-mcp

Then configure your MCP client:

Claude Desktop:

{
  "mcpServers": {
    "blogcaster": {
      "command": "npx",
      "args": ["-y", "blogcaster-mcp"]
    }
  }
}

Cursor / Cline:

{
  "blogcaster": {
    "command": "npx",
    "args": ["-y", "blogcaster-mcp"]
  }
}

Option 2: Remote Cloud Endpoint

Use the hosted Cloudflare Worker (no installation required):

MCP Endpoint:

https://blogcaster-mcp.rrpb2580.workers.dev/mcp

Claude Desktop:

{
  "mcpServers": {
    "blogcaster": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://blogcaster-mcp.rrpb2580.workers.dev/mcp"]
    }
  }
}

Cursor / Cline:

{
  "blogcaster": {
    "url": "https://blogcaster-mcp.rrpb2580.workers.dev/mcp"
  }
}

Restart the client after saving the config.

🛠️ Tools you can call

• getTokenManagementLink() — Start here. Generates a secure link to manage your tokens.
• publishPost(title, contentMarkdown, platforms, coverImageURL?) — publish to one or many blogs.

🚦 Quickstart flow

1) Setup Tokens (Do this once per session)

2) Publish a post

publishPost(
  title: "My First BlogCaster Demo",
  contentMarkdown: "# Hello World\\nPublished via MCP!",
  platforms: ["hashnode", "devto", "wordpress"],

)

❓ FAQ

Do I install anything?
No — everything runs on Cloudflare Workers (remote mode) or via NPM (local mode).

Where are tokens stored?
Secure Durable Object storage scoped to your session.

Does it remember me tomorrow?
Sessions are ephemeral. If you start a new chat, you'll need to link again (this is a security feature).

Can I self-host?
Yes, deploy the Worker and point your MCP client to your URL.

Does BlogCaster store my posts?
Only temporarily to publish; no retention.
