Syncpen MCP Server

A markdown knowledge base your AI reads, writes, and organizes — a memory in plain files you can actually open and correct (not an opaque vector store), with every agent edit signed and yours to approve.

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.

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 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.

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:

git clone https://github.com/airbuzz/syncpen-mcp.git
cd syncpen-mcp
npm install
npm 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.
