Claude Code LSPs

This repository contains a Claude Code marketplace with plugins that offer LSP servers for TypeScript, Rust, X, Y, Z. LSP servers provide powerful and familiar code intelligence features to IDEs, and now Claude Code directly.

Claude Code is going to officially support LSP soon. In 2.0.30 (October 31st) they adding the working beginnings of a system to run LSP servers from plugins automatically on startup, and an LSP tool (enable via $ENABLE_LSP_TOOL=1) that Claude can use to

• Go to the definition for symbols (goToDefinition)
• Hover over symbols (hover)
• List all the symbols in a file (documentSymbol)
• Find all references to a symbol (findReferences)
• Search for symbols across the workspace (workspaceSymbol)

[!warning] Support for LSP in Claude Code is pretty raw still. There are bugs in the different LSP operations, no documention, and no UI indication that your LSP servers are started/running/have errors or even exist. But it's there, and with tweakcc you can make it work.

Patching Claude Code

You can manually patch it, but it's much easier to use tweakcc to automatically detect your Claude Code installation (npm or native) apply the necessary patches.

Run npx tweakcc --apply. It will automatically patch your Claude Code installation to make LSP support usable. (It also does a bunch of other things like let you customize all the system prompt parts, create new CC themes, change the thinking verbs, and a lot more.)

If you'd like to apply the patches yourself, go the bottom of this page.

Installing the plugins

Install them the usual way. First make CC aware of the marketplace:

1. Run claude
2. /plugin marketplace add Piebald-AI/claude-code-lsps

Then enable the plugins of your choice:

1. Run claude
2. Type /plugins
3. Choose Browse and install plugins
4. Enter the Claude Code Language Servers marketplace
5. Select the plugins you'd like with the spacebar (e.g. TypeScript, Rust)
6. Press "i" to install them
7. Restart Claude Code

Here's a screenshot:
