 # MCP Interceptors - C# SDK
 
 ## What this is
-C# implementation of gateway-level interceptors from [SEP-1763](https://github.com/modelcontextprotocol/modelcontextprotocol/issues/1763). NuGet package additive to the official [C# MCP SDK](https://github.com/modelcontextprotocol/csharp-sdk) (v1.1.0). Focus is on the protocol-level extension (client → interceptor server → server), NOT in-process middleware.

 **`InterceptingMcpClient` is composition**: `McpClient` has an internal constructor; subclassing is `[Experimental]`. We wrap it as a concrete class exposing `.Inner` for direct access.
