Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "syncpen": {
      "command": "npx",
      "args": [
        "-y",
        "syncpen-mcp"
      ],
      "env": {
        "SYNCPEN_API_KEY": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add syncpen --env SYNCPEN_API_KEY=your-value -- npx -y syncpen-mcp

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "syncpen": {
      "command": "npx",
      "args": [
        "-y",
        "syncpen-mcp"
      ],
      "env": {
        "SYNCPEN_API_KEY": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "syncpen": {
      "type": "stdio",

      ],
      "env": {
        "SYNCPEN_API_KEY": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Common questions

Is Syncpen safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: SYNCPEN_API_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.6.3) reached the registry 4 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

Syncpen MCP Server

Connect Claude Code (or any MCP client) to your Syncpen workspace — the writing workspace your AI can actually write in. Your agent can search, read, draft, suggest, comment, organize, and publish in the same live documents you edit.

Don't have an account yet? Create one free at [syncpen.io](https://www.syncpen.io).

What is Syncpen great at?

Build a knowledge base your AI maintains — capture notes, docs, and clips, then let your agent organize, cross-link, and keep it current.
Write long-form where you publish — articles, docs, whole books; your agent drafts, you approve, and one call ships it to WordPress, Ghost, or Sanity.
Your agents and you on one project — everyone works in the same live documents; every edit is shared, legible, and attributed.
Edits with a paper trail — agents propose changes as signed suggestions you accept or reject. Nothing changes silently.
Research → draft → ship without leaving your tools — clip sources, let your AI draft from them, publish.

Quick Setup

1. Generate an API Key

Go to [Settings → API Keys](https://www.syncpen.io/settings/api-keys) in your Syncpen account
Enable API Access
Create a new API key
Copy the key (you'll only see it once!)

2. Configure Claude Code

Add to your MCP configuration file (~/.mcp.json or project-level .mcp.json):

"mcpServers": { "syncpen": { "command": "npx", "args": ["-y", "syncpen-mcp"], "env": { "SYNCPEN_API_KEY": "sp_your_api_key_here" } } } }

That's it! Claude Code will automatically download and run the MCP server.
