A command that sets up language-server checks for the current project. It can detect supported languages, verify or offer to install their servers, configure hooks, and update CLAUDE.md with guidance.

Use it to configure LSP support for languages including TypeScript, JavaScript, Python, Markdown, and Terraform, with options to skip installation, hooks, documentation changes, or run verification only.

It gathers several setup tasks into one workflow and shows which language services are ready.

Install

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

git clone --depth 1 https://github.com/zircote/lsp-tools

Made for: Claude Code.

Or install lsp-tools, the plugin that ships this one along with the rest of its 1 skill, 4 commands, 2 hooks.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00020	$0.04535
Opus 5.5	$0.00008	$0.01814
Sonnet 5.5	$0.00004	$0.00907
Haiku 4.5	$0.00002	$0.00453

Security

Grade B, and why

lsp-setup 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 2mo ago.

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.

Unrestricted tool accessmediumExcessive agency

A wildcard tool grant or "run any command" leaves no least-privilege boundary at all.

NAME
    lsp-setup - Set up LSP hooks, verify servers, and configure CLAUDE.md

SYNOPSIS
    /lsp-tools:lsp-setup [language...] [options]

DESCRIPTION
    Complete LSP toolchain setup: detects languages (including Markdown and
    Terraform), verifies LSP servers are installed, offers to install missing
    servers, configures hooks, and updates CLAUDE.md with LSP guidance.

    SPECIALIZED PLUGINS: If zircote/*-lsp plugins are installed (rust-lsp,
    terraform-lsp, markdown-lsp), hooks for those languages are skipped since
    the specialized plugins provide their own hooks.

OPTIONS
    --help, -h           Show this help message
    --skip-install       Skip LSP server installation prompts
    --skip-hooks         Skip hooks installation
    --skip-claudemd      Skip CLAUDE.md modifications
    --verify-only        Only verify LSP servers, don't install anything

LANGUAGES
    TypeScript/JavaScript, Python, Go, Rust, Java, Kotlin, C/C++, C#,
    PHP, Ruby, HTML/CSS, LaTeX, Markdown, Terraform

SPECIALIZED PLUGINS (hooks provided by plugin, not lsp-tools)
    zircote/rust-lsp       16 hooks (clippy, security, dependencies)
    zircote/terraform-lsp  17 hooks (tflint, trivy, checkov, terragrunt)
    zircote/markdown-lsp   4 hooks (links, frontmatter, code blocks, syntax)

EXAMPLES
    /lsp-tools:lsp-setup                     Auto-detect and full setup
    /lsp-tools:lsp-setup typescript python   Setup specific languages
    /lsp-tools:lsp-setup --verify-only       Check LSP server status
    /lsp-tools:lsp-setup --skip-install      Setup hooks only
