Implementation Reference

• src/dicom_mcp/server.py:237-255 (handler)

  The handler function for the 'add-note' tool within the @server.call_tool() method. It extracts 'name' and 'content' from arguments, validates them, stores the note in the global 'notes' dict, notifies clients of resource list changes, and returns a TextContent confirmation.

  if name == "add-note":
      note_name = arguments.get("name")
      content = arguments.get("content")
  
      if not note_name or not content:
          raise ValueError("Missing name or content")
  
      # Update server state
      notes[note_name] = content
  
      # Notify clients that resources have changed
      await server.request_context.session.send_resource_list_changed()
  
      return [
          types.TextContent(
              type="text",
              text=f"Added note '{note_name}' with content: {content}",
          )
      ]

• src/dicom_mcp/server.py:154-165 (registration)

  Registration of the 'add-note' tool in the @server.list_tools() handler, including name, description, and input schema definition.

  types.Tool(
      name="add-note",
      description="Add a new note",
      inputSchema={
          "type": "object",
          "properties": {
              "name": {"type": "string"},
              "content": {"type": "string"},
          },
          "required": ["name", "content"],
      },
  ),

• src/dicom_mcp/server.py:157-164 (schema)

  JSON schema for 'add-note' tool inputs, requiring 'name' and 'content' as strings.

  inputSchema={
      "type": "object",
      "properties": {
          "name": {"type": "string"},
          "content": {"type": "string"},
      },
      "required": ["name", "content"],
  },

• src/dicom_mcp/server.py:25-25 (helper)

  Global dictionary used to store notes by name, serving as the persistent storage for the 'add-note' tool.

  notes: dict[str, str] = {}  # Keep the notes functionality for backward compatibility
