.NET MCP Anycall Mobile Sample

This solution contains a Streamable HTTP MCP server and a Blazor Server chat/table app for Anycall mobile phone price lists.

Projects

DotNetMcpSseServer

• Hosts MCP tools at /mcp with bearer-token protection.
• Hosts REST APIs at /api/phones.
• Stores dated Anycall price snapshots in SQLite.
• Seeds the first SQLite snapshot from Features/Api/anycall-mobile-data.json.
• Imports pasted or uploaded Anycall plain text atomically: if parsing has fatal row errors, the selected date is not changed.
• Exports the selected snapshot to Excel.

DotNetMcpBlazorSample

• Chat-first UI at /.
• Date-aware phone table at /phones.
• Plain-text snapshot import page at /imports.
• Uses REST for table/import/export workflows.
• Uses MCP tools for grounded chat facts, with optional Hugging Face wording through HF_TOKEN.

Key Endpoints

• GET /api/phones?date=yyyy-MM-dd
• GET /api/phones/search?brand=Apple&maxPrice=5000000&date=yyyy-MM-dd
• GET /api/phones/brands?date=yyyy-MM-dd
• GET /api/phones/snapshots
• POST /api/phones/snapshots/import-text
• POST /api/phones/import/text
• GET /api/phones/price-diff?fromDate=yyyy-MM-dd&toDate=yyyy-MM-dd
• GET /api/phones/export/excel?date=yyyy-MM-dd

MCP Tools

• search_mobile_phones
• get_phone_by_brand
• get_phones_by_price_range
• list_brands
• get_cheapest_phones
• list_price_dates
• compare_mobile_phone_prices

Most phone tools accept an optional date argument. Price comparison accepts optional fromDate and toDate; when omitted, it compares the latest two available snapshots.

Configuration

Server SQLite database:

{
  "ConnectionStrings": {
    "MobilePhones": "Data Source=Data/anycall-mobile.db"
  }
}

Blazor MCP and Hugging Face settings:

{
  "McpServer": {
    "Url": "http://localhost:5194/mcp",
    "AuthToken": "my-super-secret-password-123"
  },
  "HuggingFace": {
    "BaseUrl": "https://router.huggingface.co/v1/chat/completions",
    "Model": "meta-llama/Llama-3.1-8B-Instruct"
  }
}

Set HF_TOKEN or user secrets for Hugging Face. Do not commit HuggingFace:ApiToken.
