glider 6.13.0

Glider - Semantic C# MCP Server

Glider is a semantic C#/.NET MCP server for code navigation, diagnostics, analysis, and refactoring.

Install

Prerequisite: .NET 10 SDK.

dotnet tool install --global glider

If install fails, run dotnet --version first. If dotnet is missing or below 10, install .NET 10 from: https://dotnet.microsoft.com/download/dotnet/10.0

Run Modes

Stdio (default)

glider

HTTP

glider --transport http

Default HTTP MCP endpoint: http://localhost:5001/mcp

Useful flags:

glider --default-timeout 30m
glider --build-host netframework
glider --msbuild-path "C:\Program Files\Microsoft Visual Studio\2022\Community\MSBuild\Current\Bin"
glider --port 8080
glider --verbose
glider --help
glider --version

--default-timeout supports ms, s, and m suffixes. Use 0 to disable server-side timeout. --build-host accepts auto, netframework, and netcore. It changes Roslyn's remote build-host selection, not the Glider server runtime. --msbuild-path points Roslyn's remote build-host process at a specific MSBuild installation by setting its MSBUILD_EXE_PATH environment.

Why you might need them:

• Use --build-host netframework when Roslyn auto-selects the wrong host family for legacy Windows solutions. This is common for older ASP.NET, desktop, test, and non-SDK projects that evaluate better inside the .NET Framework build host than the .NET Core one.
• Use --msbuild-path when the host family is correct but Roslyn still picks the wrong toolset inside that host. This matters when multiple MSBuild installs exist on the machine and a solution only loads cleanly with one specific Visual Studio or SDK toolset.
• In practice, --build-host answers "which Roslyn build-host process should evaluate the project?" and --msbuild-path answers "which MSBuild install should that process use once it starts?"

Capabilities

• Solution/project lifecycle: load, sync, reload, unload
• Discovery and inspection: find_code, search_symbols, resolve_symbol, get_symbol_info, get_symbol_at_position
• References and hierarchy: find_references, find_overrides, find_implementations, get_type_hierarchy, find_callers
• Diagnostics and code search: get_diagnostics, diagnostic_hotspots, semantic_query, search_text
• Refactoring and edits: rename_symbol, move_type, move_member, organize_usings, format_document, write_file
• Dependency and impact analysis: analyze_change_impact, get_cascade_impact, get_project_graph, find_package_usages
• Batch execution: batch

For general code navigation, find_code is the recommended first tool to try. For deeper operational guidance and tool-selection heuristics, use the repository docs.

Version Expiration

Each Glider version expires 1 month after release date.

dotnet tool update --global glider

Troubleshooting

• If glider is not found after install, ensure ~/.dotnet/tools is on PATH.
• If load fails with MSBuild initialization errors, rerun with --verbose and inspect returned diagnostics.
• For legacy .NET Framework web, desktop, or test solutions on Windows, retry with --build-host netframework when auto selects an incompatible Roslyn build host.
• If the host kind is already correct but the wrong MSBuild toolset is still being used, add --msbuild-path and point it at the desired Visual Studio or SDK MSBuild location.
• On Windows, stable Visual Studio installs are preferred for legacy/.NET Framework solutions.
