Implementation Reference

• src/index.ts:161-177 (handler)

  Handler for the create_note tool. It extracts title and content from arguments, validates them, generates a new ID, stores the note in the in-memory notes object, and returns a success message with the new note ID and title.

  case "create_note": {
    const title = String(request.params.arguments?.title);
    const content = String(request.params.arguments?.content);
    if (!title || !content) {
      throw new Error("Title and content are required");
    }
  
    const id = String(Object.keys(notes).length + 1);
    notes[id] = { title, content };
  
    return {
      content: [{
        type: "text",
        text: `Created note ${id}: ${title}`
      }]
    };
  }

• src/index.ts:110-123 (schema)

  Input schema for the create_note tool, defining an object with required 'title' and 'content' string properties.

  inputSchema: {
    type: "object",
    properties: {
      title: {
        type: "string",
        description: "Title of the note"
      },
      content: {
        type: "string",
        description: "Text content of the note"
      }
    },
    required: ["title", "content"]
  }

• src/index.ts:107-124 (registration)

  Registration of the 'create_note' tool within the ListToolsRequestSchema handler, specifying name, description, and input schema.

  {
    name: "create_note",
    description: "Create a new note",
    inputSchema: {
      type: "object",
      properties: {
        title: {
          type: "string",
          description: "Title of the note"
        },
        content: {
          type: "string",
          description: "Text content of the note"
        }
      },
      required: ["title", "content"]
    }
  },
