Pull request overview
This PR upgrades the ModelContextProtocol library from version 0.3.0-preview.4 to 0.5.0-preview.1, along with corresponding updates to ModelContextProtocol.AspNetCore. The upgrade requires refactoring the InstrumentedTool class to use a traditional constructor instead of a primary constructor and implementing the required Metadata property override. Additionally, API changes in the MCP library necessitate replacing IMcpClient interface references with the concrete McpClient class and updating McpClientFactory.CreateAsync calls to McpClient.CreateAsync.
Key Changes
- Upgraded ModelContextProtocol packages from 0.3.0/0.1.0 preview versions to 0.5.0-preview.1
- Refactored
InstrumentedToolfrom primary constructor to traditional constructor with explicit field initialization - Migrated from
