Semantic Pen MCP Server

A one-click MCP server for Semantic Pen that allows you to create, view, and manage articles and projects directly from Claude Code and Cursor.

Quick Setup (Recommended)

Just add this to your MCP configuration - no installation required!

Add to your ~/.config/claude-code/settings.json:

{
  "mcpServers": {
    "semantic-pen": {
      "command": "npx",
      "args": ["-y", "@semanticpen/mcp-server@latest"],
      "env": {
        "SEMANTIC_PEN_API_KEY": "your-api-key-here"
      }
    }
  }
}

Add to your Cursor MCP settings:

{
  "mcpServers": {
    "semantic-pen": {
      "command": "npx",
      "args": ["-y", "@semanticpen/mcp-server@latest"],
      "env": {
        "SEMANTIC_PEN_API_KEY": "your-api-key-here"
