mcpdotnet 1.0.0 - Full MCP Support

We're excited to announce mcpdotnet 1.0.0, bringing complete Model Context Protocol support to .NET applications! This release marks a significant milestone with the addition of server capabilities alongside our existing client implementation.

Major Features

• Server Support: Create MCP-compliant servers using the new McpServer class and server factory
• Shared Core Architecture: Robust shared endpoint implementation handling JSON-RPC messaging and lifecycle management
• Transport Flexibility:
  • Built-in support for stdio transport (Windows)
  • SSE client transport (cross-platform)
  • Extensible transport system for custom implementations
• Full Protocol Compliance: Complete implementation of the MCP specification for both clients and servers

Getting Started

Check out our updated documentation with examples for both client and server implementations. The README includes a simple echo server example to help you get started with server development.

Roadmap

Future releases will bring:

• SSE server transport support
• Cross-platform stdio transport
• Authentication capabilities
• Additional examples and documentation

Breaking Changes

None - this is a feature addition release building on our stable client implementation.
