Margen MCP

A read-only MCP server that allows AI assistants like Claude and ChatGPT to search, read, and summarize handwritten notes from ONYX Boox tablets. It transcribes handwriting in the background and makes notes accessible via AI tools, supporting use cases like flashcard generation, meeting note summarization, and keyword search.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.

Claude Code configuration

claude mcp add --transport http margen-mcp https://connector.getmargen.app/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).

Codex configuration

codex mcp add margen-mcp --url https://connector.getmargen.app/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable margen-mcp in your MCP settings.

Cursor configuration

{
  "mcpServers": {
    "margen-mcp": {
      "url": "https://connector.getmargen.app/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).

Cline configuration

{
  "mcpServers": {
    "margen-mcp": {
      "type": "streamableHttp",
      "url": "https://connector.getmargen.app/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start margen-mcp and inspect its tools.

VS Code configuration

{
  "servers": {
    "margen-mcp": {
      "type": "http",
      "url": "https://connector.getmargen.app/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.

Gemini CLI configuration

gemini mcp add --transport http margen-mcp https://connector.getmargen.app/mcp

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.

Claude Desktop configuration

{
  "mcpServers": {
    "margen-mcp": {
      "url": "https://connector.getmargen.app/mcp"
    }
  }
}

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.

Windsurf configuration

{
  "mcpServers": {
    "margen-mcp": {
      "serverUrl": "https://connector.getmargen.app/mcp"
    }
  }
