RemNote MCP Bridge

Connect RemNote to AI assistants (Claude, GPT, etc.) via the Model Context Protocol (MCP). This plugin enables bidirectional communication, allowing AI to read and write directly to your RemNote knowledge base.

What is MCP?

Model Context Protocol is an open standard by Anthropic that allows AI assistants to interact with external tools and data sources. With this plugin, your AI assistant becomes a true PKM companion.

Development

# Install dependencies
npm install

# Run in development mode (hot reload)
npm run dev

# Build for production
npm run build

# The plugin zip will be created as PluginZip.zip

Troubleshooting

Plugin shows "Disconnected"

• Ensure the MCP server is running (remnote-mcp-server)
• Check the WebSocket URL in settings (default: ws://127.0.0.1:3002)
• Look for errors in RemNote's developer console (Cmd+Option+I)

"Invalid event setCustomCSS" errors

• These are cosmetic errors from development mode
• They don't affect functionality
• They won't appear in production builds

Notes not appearing

• Check if a default parent ID is set (might be creating under a specific Rem)
• Verify the auto-tag setting isn't filtering your view
