lsp-plugin

@jgoz/cli-lsp-client

CLI tool for getting LSP diagnostics. Uses a background daemon to keep LSP servers running.

Features

• Get diagnostics from LSP servers
• Get hover information for symbols (functions, variables, types)
• Background daemon for fast repeated requests
• Built in Claude Code hook to provide feedback on file edit tool calls
• Comprehensive daemon management (list, stop-all commands)
• Multi-project support with isolated daemon instances per directory
• Custom language server support via config files

How It Works

• Daemon starts automatically when needed
• LSP servers spawn based on file type
• Finds project roots using config files (tsconfig.json, etc.)
• Servers stay running for subsequent requests

Claude Code Integration

Plugin Installation (Recommended)

The easiest way to integrate with Claude Code is via the official plugin:

# Add the plugin marketplace
/plugin marketplace add jgoz/cli-lsp-client

# Install the plugin
/plugin install lsp-plugin

This automatically configures:

• SessionStart hook: Starts the LSP daemon when Claude Code starts
• PostToolUse hook: Runs diagnostics after file edits (Edit, Write, MultiEdit)

No manual configuration needed - the plugin handles everything!
