  Handler for the 'set_operator_key' tool which updates the API key in the session state.

  case 'set_operator_key': {
    const parsed = SetOperatorKeySchema.parse(args);
    session.setClient(new LightningFaucetClient(parsed.api_key));
    return {
      content: [
        {
          type: 'text',
          text: JSON.stringify({
            success: true,
            message: 'Switched to operator credentials. Subsequent requests will use this API key.',
          }, null, 2),
        },
      ],
    };
  }

• src/index.ts:147-150 (schema)

  Schema for validating the input to 'set_operator_key'.

  const SetOperatorKeySchema = z.object({
    api_key: z.string().min(10, 'API key is too short').max(200, 'API key is too long')
      .describe('The operator API key to use for subsequent requests'),
  });

• src/index.ts:449-458 (registration)

  Tool registration for 'set_operator_key'.

    name: 'set_operator_key',
    description: 'Switch to a different operator API key for subsequent requests. Use after register_operator to start using the new credentials.',
    inputSchema: {
      type: 'object',
      properties: {
        api_key: { type: 'string', description: 'The operator API key' },
      },
      required: ['api_key'],
