Overview

AI-generated overview

Connects an AI assistant to a Syncpen markdown workspace so it can search, read, draft, suggest edits, comment, organize and publish documents.

What you can do
  • Search and read documents as markdown, and list folders and documents
  • Create and update documents, and propose edits as pending suggestions for a human to accept or reject
  • Read, reply to and resolve comment threads
  • Create, rename, move and delete folders and documents
  • Publish documents to WordPress, Ghost or Sanity, and list connected CMS targets
  • Review recent workspace changes, related documents and team spaces
When to use it
Useful when your writing or knowledge base lives in Syncpen and you want an assistant to draft, cross-link, comment on or publish it while keeping human approval over changes. Also handy for pulling in connected Drive, Notion, Slack and news sources during research.
Requirements
Runs locally over stdio, typically via npx with the syncpen-mcp package, so Node.js is needed. Requires a Syncpen account with API access enabled and an API key supplied in the SYNCPEN_API_KEY environment variable. Optional SYNCPEN_API_URL targets a non-production instance. Connected Drive, Notion, Slack, World News and CMS integrations must be set up in the Syncpen account.
Before you install
The API key in SYNCPEN_API_KEY grants access to your workspace and is shown only once, so store it carefully. Tools can create, update, move and delete documents and folders, reply to comments and publish to external CMS targets; deletions go to trash but publishing and replies are visible to others. Content from connected Google Drive, Notion, Slack and news services is sent through the Syncpen API.

Installation

In SourceWeft

  1. Open Syncpen in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

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.

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

  1. Go to Settings → API Keys in your Syncpen account
  2. Enable API Access
  3. Create a new API key
  4. 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):

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.

Usage Examples

Once configured, ask Claude Code:

  • "List my Syncpen folders"
  • "Search for documents that mention authentication"
  • "Read my document titled 'API Design Notes'"
  • "What documents do I have in my 'Projects' folder?"
  • "Publish my 'Launch Post' document to Ghost as a draft"
  • "What's changed in my workspace since yesterday?"

Development

For contributing or running from source:

bash
git clone https://github.com/airbuzz/syncpen-mcp.gitcd syncpen-mcpnpm installnpm run build     # or: npm run dev  (watch mode)

Point your MCP config at the built entry (node /path/to/syncpen-mcp/dist/index.js). It uses the production API by default; set SYNCPEN_API_URL only to target a local instance.
