Your AI assistant’s .NET expert

DotNetMCP gives every AI coding assistant deep .NET expertise through the Model Context Protocol. It works with Claude Code, Cursor, Windsurf, and any MCP-compatible tool.

Instead of relying on the AI’s training data alone (which may be outdated or incomplete), DotNetMCP feeds your assistant curated, up-to-date .NET knowledge in real time — covering modern patterns, performance optimization, security best practices, and migration strategies.

Built for the community

DotNetMCP is sponsored by Noundry and free for all .NET developers. No signup, no API keys, no rate limits. Just connect and go.

Upgrading a .NET 6 project to .NET 10

Ask your AI assistant to help with the migration. DotNetMCP provides a step-by-step plan with breaking change alerts, deprecated API replacements, and new feature recommendations.

> Help me migrate this project from .NET 6 to .NET 10
[dotnetmcp:plan_migration]
Migration plan generated: 12 steps, 3 high-risk changes, 2 deprecated APIs to replace...

Catching performance issues before PR review

DotNetMCP detects anti-patterns like N+1 queries, sync-over-async calls, and allocation-heavy code that would otherwise slip through code review.

> Review this EF Core repository for performance issues
[dotnetmcp:detect_antipatterns]
Found: N+1 query in GetOrdersWithItems(), missing AsNoTracking() on read-only queries...

Learning modern C# patterns

Ask about any .NET topic and get accurate, up-to-date guidance with code examples that follow current best practices.

> What’s the modern way to handle options validation in .NET?
[dotnetmcp:search_guides]
Use ValidateDataAnnotations() + ValidateOnStart() for fail-fast configuration...
