Implementation Reference

• src/server.ts:357-370 (registration)

  Registration of the 'get_resource' tool in the ListTools response, including name, description, and input schema definition.

  {
    name: 'get_resource',
    description: 'Get detailed information about a specific Azure resource',
    inputSchema: {
      type: 'object',
      properties: {
        resourceId: {
          type: 'string',
          description: 'Full Azure resource ID',
        },
      },
      required: ['resourceId'],
    },
  },

• src/server.ts:452-477 (handler)

  Handler implementation for the 'get_resource' tool. It fetches the topology, finds the resource by ID, and returns formatted details including name, type, group, location, subscription, ID, tags, and properties.

  case 'get_resource': {
    const { resourceId } = args as { resourceId: string };
    const topology = await buildTopology();
    const resource = topology.nodes.find(n => n.id === resourceId);
    
    if (!resource) {
      throw new McpError(ErrorCode.InvalidRequest, `Resource not found: ${resourceId}`);
    }
    
    return {
      content: [
        {
          type: 'text',
          text: `Resource Details:\n\n` +
            `Name: ${resource.name}\n` +
            `Type: ${resource.type}\n` +
            `Resource Group: ${resource.resourceGroup}\n` +
            `Location: ${resource.location}\n` +
            `Subscription: ${resource.subscriptionId}\n` +
            `ID: ${resource.id}\n\n` +
            (resource.tags ? `Tags: ${JSON.stringify(resource.tags, null, 2)}\n\n` : '') +
            (resource.properties ? `Properties: ${JSON.stringify(resource.properties, null, 2)}` : ''),
        },
      ],
    };
  }
