🚨 MANDATORY: Invoke docs-management First
STOP - Before providing ANY response about LSP configuration:
- INVOKE
docs-managementskill for Claude Code LSP documentation- QUERY for the user's specific LSP topic
- BASE all responses on official documentation + this skill's knowledge base
Skipping this step results in outdated or incorrect information.
LSP support in Claude Code is experimental and has known issues. Key points:
| Requirement | Details |
|-------------|---------|
| Environment Variable | ENABLE_LSP_TOOL=1 (singular) required to expose LSP tool |
| Current Version | v2.1.0+ has partial support (regression #17468) |
| Stable Version | v2.0.67 is last known stable LSP version |
| Configuration | .lsp.json at project root or lspServers in plugin.json |
See troubleshooting.md for version-specific issues and workarounds.

Claude Code reads LSP configuration from .lsp.json in the project root.
Basic Structure:
{
"server-name": {
"command": "server-executable",
"args": ["--stdio"],
"extensionToLanguage": {
".ext": "language-id"
},
"restartOnCrash": true,
"maxRestarts": 3
}
}
Required Fields:
| Field | Type | Description |
| --- | --- | --- |
| command | string | Executable command for the server |
| args | string[] | Command-line arguments (typically ["--stdio"]) |
| extensionToLanguage | object | Maps file extensions to language IDs |
Optional Fields:
| Field | Type | Default | Description |
| --- | --- | --- | --- |
| restartOnCrash | boolean | true | Auto-restart server on crash |
| maxRestarts | number | 3 | Maximum restart attempts |
For complete patterns and examples, see configuration-patterns.md.

| Extensions | Language | Recommended Server |
| --- | --- | --- |
| .py, .pyi | Python | pyright |
| .ts, .tsx, .js, .jsx | TypeScript/JavaScript | typescript-language-server |
| .go | Go | gopls |
