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.
