lsp-install

A command that sets up Language Server Protocol tools for Claude Code. LSP is a standard connection that lets a coding tool understand definitions, references, types, and errors in a project.

In plain words
What is it for?
Use it to choose and install language servers for projects using TypeScript, Python, Go, Java, PHP, Swift, Kotlin, C/C++, Rust, or C#.
Why use it?
It can make code navigation more precise than searching for matching words in text. It is intended to reduce unnecessary file reading and catch some type errors while editing.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo

Per session 18 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

lsp-install scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

fireauto-lsp: Claude Code LSP 원클릭 셋업

Claude Code에 LSP(Language Server Protocol)를 연결해서 코드 탐색 속도와 정확도를 극대화하는 커맨드예요.

모든 출력은 **한국어(토스체)**로 작성해요.


LSP가 뭔지 간단히 설명

Claude Code는 기본적으로 코드를 찾을 때 **텍스트 검색(grep)**을 써요. LSP를 켜면 VS Code의 "정의로 이동(Ctrl+Click)"처럼 코드 구조를 이해하면서 찾아요.

  • 속도: 수십 초 → 50ms
  • 정확도: 비슷한 단어 → 정확한 호출 계층
  • 에러 감지: 편집 직후 타입 에러 즉시 포착
  • 토큰 절약: 엉뚱한 파일 안 읽으니까 비용도 절약

Step 1: 어떤 개발을 하시나요?

먼저 사용자에게 개발 분야를 물어보세요. 초보자도 쉽게 고를 수 있도록 선택지를 보여줘요:

어떤 개발을 하고 계세요? (번호로 골라주세요, 여러 개 가능!)

1. 웹 개발 (React, Next.js, Vue 등)
2. 백엔드 개발 (Python, Go, Java 등)
3. iOS/macOS 앱 개발 (Swift)
4. 안드로이드 앱 개발 (Kotlin)
5. 시스템/임베디드 (C/C++, Rust)
6. 게임 개발 (C#/Unity)
7. 잘 모르겠어요 (프로젝트 자동 감지해줘!)

선택에 따라 설치할 항목을 매핑하세요:

선택 설치되는 LSP 설치 명령 플러그인
1. 웹 개발 typescript-language-server npm i -g typescript-language-server typescript typescript-lsp
2. 백엔드 (Python) pyright npm i -g pyright pyright-lsp
2. 백엔드 (Go) gopls go install golang.org/x/tools/gopls@latest gopls-lsp
2. 백엔드 (Java) jdtls brew install jdtls jdtls-lsp
2. 백엔드 (PHP) intelephense npm i -g intelephense php-lsp
3. iOS/macOS sourcekit-lsp (Xcode에 포함) swift-lsp
4. 안드로이드 kotlin-language-server brew install kotlin-language-server kotlin-lsp
5. 시스템 (C/C++) clangd brew install llvm clangd-lsp
5. 시스템 (Rust) rust-analyzer rustup component add rust-analyzer rust-analyzer-lsp
6. 게임 (C#) csharp-ls dotnet tool install -g csharp-ls csharp-lsp

"7. 잘 모르겠어요"를 선택한 경우

프로젝트 루트에서 Glob으로 아래 파일들을 자동 감지하세요:

감지 파일 언어
tsconfig.json, package.json TypeScript/JS
requirements.txt, pyproject.toml, *.py Python
go.mod Go
Cargo.toml Rust
Package.swift, *.xcodeproj Swift
pom.xml, build.gradle Java
*.csproj, *.sln C#
composer.json PHP
CMakeLists.txt + *.c/*.cpp C/C++
build.gradle.kts + *.kt Kotlin

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

lsp-install is a command published in the GitHub repository imgompanda/fireauto (140 stars, last pushed 4mo ago), licensed MIT. It adds 18 tokens to every session and 1,696 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
