  • syncpen_delete_folderwrite action

  • syncpen_list_comments

    Read the comment threads on a document (top-level comments with their replies, line numbers, authors, and resolved state).

  • syncpen_list_connections

    List your connected CMS targets (WordPress, Ghost, Sanity) and their connectionIds. Use before syncpen_publish to find the connectionId when a target has more than one active connection.

  • syncpen_list_documents

    List documents in your SyncPen account, optionally filtered by folder.

  • syncpen_list_folders

    List all folders in your SyncPen account.

  • syncpen_list_suggestions

    List a document's suggestions so you can see what is still pending. Defaults to pending only; pass status 'all' to include accepted/rejected.

  • syncpen_move_document

    Move a document into a folder, or to the root (un-foldered).

  • syncpen_move_folder

    Move a folder under a new parent folder, or to the root. Rejects circular moves and moves that exceed the nesting depth limit.

  • syncpen_publishwrite action

    Publish a SyncPen document to a connected CMS (WordPress, Ghost, or Sanity). Auto-selects the connection when only one is active for the target; otherwise pass connectionId.

  • syncpen_read

    Read a SyncPen document's content as markdown. Use the document ID from search or list results.

  • syncpen_recent_changes

    A time-ordered feed of recent workspace changes — who created, edited, or trashed which documents, and when. Surfaces both in-app human edits and agent/API writes. Use it to catch up on what changed since you last looked (pass `since`), or to scope to one folder.

  • syncpen_rename_folder

    Rename an existing SyncPen folder.

  • syncpen_reply_comment

    Reply to a comment thread. The reply is posted under the agent's name and notifies any @mentioned members.

  • syncpen_resolve_comment

  • syncpen_search

    Search SyncPen documents by title and body content (full text). Use this to find documents about a specific topic.

  • syncpen_suggest_edit

    Propose an edit to a document as a pending suggestion that a human accepts or rejects in the editor. The document is NOT changed until accepted. Use this instead of syncpen_update when you want human approval. Anchor the edit either by character offsets {from,to} or by a unique snippet {text} to replace.

  • syncpen_updatewrite action

    Update an existing SyncPen document's title and/or content.

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

  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):

{
  "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.
