tree-sitter-language-pack

Parse and understand source code in 306 languages, from the language you already work in — with one dependency and no grammars to compile.

What and Why?

Add one package and you can parse any of 306 languages, walk their syntax trees, pull out functions, classes, imports, and symbols, and split code into chunks an LLM can use. It works the same whether you call it from Python, Node.js, Go, Java, C#, Ruby, PHP, Elixir, and eight more, or from the shell via the CLI and MCP server.

tree-sitter gives fast, incremental parsers for individual languages, but wiring up hundreds of grammars — and reaching them from a non-C ecosystem — is the hard part. tree-sitter-language-pack does that work for you: it bundles the most comprehensive set of grammars available behind a single API, ships native bindings for 15 languages, and downloads each parser on first use so the install stays small.

Reach for it whenever you need to process, inspect, or analyze code — building developer tooling, feeding a RAG pipeline, or giving an agent structural understanding of a codebase.

Features

Feature	Description
306 languages	Pre-compiled parsers at ABI 14 (backwards compatible with tree-sitter 0.21–0.26)
Code intelligence	Extract functions, classes, imports, docstrings, and symbols from source
Data extraction	Hierarchical key-value trees from 17 config/data formats (JSON, YAML, TOML, XML, CSV, …)
Host-native language API	get_language() returns native Language objects in Python, Node.js, Go, Java, C#, Kotlin, Swift, Zig, and C
On-demand downloads	Parsers are fetched on first use and cached locally for fast, offline reuse
Prefetch & warming	prefetch() loads (and downloads) every grammar you need up front, so hot loops only parse
Bundled queries	highlights, injections, locals, tags, indents, and folds .scm queries per language, with a process-wide compiled-query cache (Rust)
Selective installation	Download only the languages you need; unused parsers are never downloaded
Polyglot bindings	Native bindings across 15 languages, including a C ABI for everything else
CLI & MCP server	ts-pack download to pre-fetch parsers; MCP integration for AI agents

Supported Languages

This pack includes 306 languages. See the full language list for every supported grammar with extensions and repository links.

Grammars & Bundled Queries

Each grammar bundles a subset of the six standard tree-sitter query types. The table below shows which .scm queries ship with every grammar.

CLI

cargo install ts-pack-cli

brew tap xberg-io/homebrew-tap
brew install xberg-io/homebrew-tap/ts-pack

Or run without a persistent install (the proxy package fetches the native binary):

npx @xberg-io/ts-pack-cli parse <file>
uvx --from ts-pack-cli ts-pack parse <file>

See CLI README for full documentation.

MCP Server

The CLI bundles an MCP server for integration with AI agents. Start it with:

ts-pack mcp

The server runs over stdio by default. For HTTP transport:

ts-pack mcp --transport http --host 127.0.0.1 --port 8011

Register with Claude Code:

claude mcp add ts-pack -- ts-pack mcp

Or add to your Claude Desktop config at ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "ts-pack": {
      "command": "ts-pack",
      "args": ["mcp"]
    }
  }
}

The MCP server exposes 8 tools: parse, process, detect_language, list_languages, info, download, cache_dir, and clean_cache. It also provides resources for the available language catalog and a prompt for code analysis.

The marketplace plugin from xberg-io/plugins auto-registers the server — see AI Coding Assistants below to install it instead of manual registration.

For detailed setup, transport options, and tool reference, see the MCP Server guide.

AI Coding Assistants
