Claude Code LSPs
A collection of Language Server Protocol (LSP) plugins for Claude Code.
What is LSP Integration?
[!NOTE] LSP Integration: If you're on v2.0.69 through v2.0.x, LSP integration is broken due to a race condition (#14803, #13952). This has been fixed in v2.1.0+. Please upgrade to the latest version.
The Language Server Protocol provides IDE-like intelligence to Claude Code. On startup, Claude Code automatically starts LSP servers from installed plugins and exposes them to Claude in two ways:
LSP Tool - A builtin tool with 9 operations mapping directly to LSP commands:
| Operation | Description |
| ---------------------- | --------------------------------------------------------------- |
| goToDefinition | Find where a symbol is defined |
| findReferences | Find all references to a symbol |
| hover | Get hover info (docs, type info) for a symbol |
| documentSymbol | Get all symbols (functions, classes, variables) in a document |
| workspaceSymbol | Search for symbols across the entire workspace |
| goToImplementation | Find implementations of an interface/abstract method |
| prepareCallHierarchy | Get call hierarchy item at a position |
| incomingCalls | Find all functions/methods that call the function at a position |
| outgoingCalls | Find all functions/methods called by the function at a position |
Automatic Diagnostics - Real-time error and warning detection similar to the VS Code integration, but operating independently. These diagnostics tend to be faster and more comprehensive than the VS Code equivalent.

Manual LSP Installation
Each plugin will attempt to auto-install its LSP server on first use. If auto-install fails, use the manual instructions below.
brew install bash-language-server
Or via npm:
npm install -g bash-language-server
brew install llvm
Or via Xcode Command Line Tools:
xcode-select --install
Supports C, C++, Objective-C (.m), and Objective-C++ (.mm) files.
brew install omnisharp/omnisharp-roslyn/omnisharp-mono
Or via dotnet:
dotnet tool install -g csharp-ls
brew install clojure-lsp
Or download from GitHub releases.
Install Dart SDK:
brew tap dart-lang/dart
brew install dart
Or install Flutter (includes Dart):
# See https://docs.flutter.dev/get-started/install
Ensure dart is in your PATH.
brew install elixir-ls
Requires Elixir to be installed:
brew install elixir
brew install gleam
Or download from GitHub releases.
