   mcp start Notes
   

2. Example operations:

   # Create a note
   await client.call_tool("add-note", {
       "name": "example",
   
            
        
            
                       "content": "This is a test note"
   })
   
   # List all notes
   await client.call_tool("list-all-notes")
   
   # Update a note
   await client.call_tool("update-note", {
       "name": "example",
       "content": "Updated content"
   })
   
   # Delete a note
   await client.call_tool("delete-note", {
       "name": "example"
   })
   

Storage

Notes are stored in notes_storage.json with the following structure:

{
    "note_name": {
        "content": "Note content",
        "created_at": "2025-01-12T11:28:16.721704",
        "modified_at": "2025-01-12T11:28:16.721704"
    }
}

Resource Access

Notes can be accessed as resources using the note:// URI scheme:

• List resources: Returns all available notes as resources
• Read resource: Access a specific note using note://internal/note_name

Prompt Generation

The server includes a prompt generation feature for note summarization:

• Supports both brief and detailed summaries
• Formats notes for language model input
• Available via the "summarize-notes" prompt

Development

To modify or extend the server:

1. Clone the repository
2. Install development dependencies
3. Make changes in the appropriate module
4. Test thoroughly before deploying

Testing

Tests should cover:

• Basic CRUD operations
• Multiple note handling
• Error cases
• Resource access
• Prompt generation
