McpClientServerDemo
A simple MCP Server & Client example with mcp.json config. The mcp.json roughly matches VSCode's settings.json, so in theory it can just import VSCode's settings.
Server (aspnet Minimal API, SSE) defines the following MCP servers:
- Youtube subtitles extractor
Client (Console app, OpenAI client) consumes the following MCP servers defined in mcp.json:
- Youtube subtitles extractor ^
- Yahoo Finance server
- Airbnb server
- Hacker News
- Simple Calculator
(just a bunch of random public cloud MCP servers for the demo purposes)

Short explanation of the problem in the video:
The video describes the "100 prisoners problem," a counterintuitive logic puzzle. There are
100 prisoners, each numbered 1 to 100, and 100 boxes, each hiding a slip with a unique prisoner
number. Each prisoner, one at a time, can open up to 50 boxes to find their own number. If all
prisoners succeed, they go free; if even one fails, all are executed. If they choose boxes
randomly, the chance of everyone surviving is astronomically small. However, using a clever
strategy-each prisoner following a chain by starting at the box with their own number and
always moving to the box whose number is on the slip they find-the probability of all surviving
rises to about 31%. The catch: it relies on the arrangement of numbered loops in the boxes,
and the math behind it is strikingly unintuitive.
