Tired of watching your coding agent fumble through C# code? Grepping file after file, missing obvious connections, bloating context with irrelevant code, and unable to peek inside third-party libraries to understand how to use them?
Glider is an MCP (Model Context Protocol) server that gives AI assistants deep semantic understanding of C# codebases. Built on Roslyn, it now provides 43 tools for code navigation, diagnostics, dependency cleanup, refactoring, and architecture analysis.
Key Features
Load and analyze .NET solutions and projects with optional automatic file watching
Get compiler and analyzer diagnostics, plus grouped hotspot summaries
Resolve and search symbols and get stable keys for precise follow-up tool calls
Find references, overrides, implementations, unused symbols, and unused parameters
Semantic symbol queries plus literal/regex text search
Navigate type hierarchies, call graphs, direct impact, and cascade impact
Get detailed type and method information
Inspect external assemblies and NuGet package usage before cleanup work
Review project graphs and identify likely-unused direct project references
Apply semantic rename and move refactorings with preview diffs
Use deterministic formatting and preview-first file writes
Get bounded source for types, methods, and external definitions
Batch multiple tool calls for faster workflows
Works with any MCP-compatible AI client
