Question 1

What is Langtools (langtools-mcp)?

Accepted Answer

Langtools (langtools-mcp) is a modular, multi-language code analysis and static-check sidecar designed to orchestrate best-in-class language tools for AI agents, LLMs, CI/CD, and developer automation workflows.

Question 2

How does Langtools perform multi-language code analysis?

Accepted Answer

Langtools uses a robust daemon architecture. It provides a unified API for analysis requests, routing them through a sidecar to the appropriate language-specific tools (like Ruff for Python) and returning normalized results as JSON.

Question 3

What are the primary use cases for Langtools?

Accepted Answer

Langtools is ideal for integrating code analysis into AI agents, LLMs (Large Language Models), CI/CD pipelines, review bots, and various developer automation workflows, especially those dealing with multi-language codebases.

Question 4

Why is Langtools suitable for LLMs and automation?

Accepted Answer

Langtools is designed to be headless and batch-friendly, enabling decoupled code analysis without direct IDE or tool dependencies. This makes it perfect for automated environments where scalable, programmatic code checks are essential.

Question 5

What programming languages does Langtools support?

Accepted Answer

Currently, Langtools provides robust support for Python (via Ruff). There are active plans to extend support to other languages, including Go (gopls), Rust (rust-analyzer), and TypeScript in future releases.
