Best .NET MCP Servers
.NET is a free, cross-platform, open-source developer platform for building many different types of applications, created by Microsoft.
Why this server?
Captures .NET/C# application logs, including console, ASP.NET, Unity, and Xbox Dev Mode profiles.
AlicenseAqualityAmaintenanceThe logs of everything on one machine — app, build, GPU, containers, serial board, OS — interleaved in the order they happened, and readable by an agent. Read-only: it can tail, search and wait, and it cannot write, delete or configure anything.296 npm1MITWhy this server?
Provides a queryable semantic map of .NET test-automation solutions, indexing projects, Gherkin features, step definitions, and dependencies into a SQLite database. Enables AI agents to resolve steps, assess impact, search scenarios, and explore project dependencies to promote reuse and avoid duplication.
Why this server?
Enables querying, reading, and modifying Microsoft SQL Server databases (part of the .NET ecosystem) through natural language, including executing SQL operations, managing tables and indexes, and performing CRUD operations on data.
AlicenseAqualityCmaintenanceA Model Context Protocol server that enables LLMs like Claude to interact with Microsoft SQL Server databases through natural language, supporting queries, data manipulation, and table management.83,267 npmMITWhy this server?
Enables debugging of .NET applications, allowing users to launch or attach to processes, set and manage breakpoints, step through code, and inspect variables, scopes, and call stacks.
AlicenseBqualityDmaintenanceAn MCP server that enables AI agents to debug .NET applications using netcoredbg. It supports core debugging tasks like setting breakpoints, stepping through code, and inspecting variables or stack traces.1MITWhy this server?
Supports .NET ASP.NET framework export format for architecture designs, generating project scaffolds in .NET.
Why this server?
Provides a Semantic Kernel plugin for .NET agents to access a marketplace of 200+ verified and quality-scored capabilities.
AlicenseAqualityCmaintenanceTrust and quality infrastructure for AI agents. 233+ quality-scored capabilities for company data, compliance checks, financial validation, and more. Every capability has a transparent SQS quality score. Audit trails on every call. EU AI Act support.85MITWhy this server?
Provides search functionality for .NET-specific AWS Lambda Powertools documentation to discover relevant implementation guides, features, and usage examples.
AlicenseAqualityFmaintenanceEnables LLMs to search through AWS Lambda Powertools documentation across multiple runtimes (Python, TypeScript, Java, .NET) using a Model Context Protocol server.274 npm42MITWhy this server?
Discovers .NET SDKs and runtimes to support application development and environmental assessment.
AlicenseAqualityBmaintenanceEncoding-aware, indentation-smart file tools for AI coding agents. 20+ tools including read/edit with automatic encoding detection, smart indentation conversion, SSH, SFTP, process management, and system utilities.1124MITWhy this server?
Analyzes C#/.NET projects to extract namespaces, classes, and routes from ASP.NET or Minimal API applications for structural navigation.
AlicenseAqualityAmaintenanceStructural graph map of any codebase. Scans entities, relationships, and feature flows across 13 languages so LLMs navigate by structure instead of reading everything.6315 PyPI58MIT
