Implementation Reference

src/index.ts:193-218 (handler)

MCP tool handler for 'uber_get_price_estimates': parses input, checks authentication, calls UberClient.getPriceEstimates, and returns JSON-formatted estimates.

case 'uber_get_price_estimates': {
  const { userId, startLatitude, startLongitude, endLatitude, endLongitude } =
    PriceEstimateSchema.parse(args);
  
  const token = userTokens.get(userId);
  if (!token) {
    throw new Error('User not authenticated. Please authorize first.');
  }
  
  uberClient.setAccessToken(token);
  const estimates = await uberClient.getPriceEstimates(
    startLatitude,
    startLongitude,
    endLatitude,
    endLongitude
  );
  
  return {
    content: [
      {
        type: 'text',
        text: JSON.stringify(estimates, null, 2),
      },
    ],
  };
}

): Promise<PriceEstimate[]> {
  const response = await this.api.get('/v1.2/estimates/price', {
    params: {
      start_latitude: startLat,
      start_longitude: startLng,
      end_latitude: endLat,
      end_longitude: endLng,
    },
  });
  return response.data.prices;
}
