Local MCP server for context-aware AI text localization
machi, developed by Qntx, is an MCP server that connects Model Context Protocol clients to local projects for AI-driven text localization. It lets language models read and modify localization files so translations reflect surrounding UI and documentation context. The tool supports structured formats like JSON and YAML, exposes a developer-friendly CLI, and automates file read/write actions, reducing repetitive manual edits during releases. It targets developers, i18n engineers, and content managers working in local workflows.
What tasks can you actually use the tool for?
The tool functions as a local MCP server that routes model requests to project files, producing translated and adapted localization strings rather than isolated phrase replacements. It handles common structured formats and automates file I/O. Concrete tasks include:
translating JSON and YAML resource files
Pros
MCP server integration connects directly to MCP-compatible clients.
Context-aware translations supply surrounding metadata to reduce literal replacements.
Developer-oriented CLI supports setup, configuration, and server management.
Supports common localization formats such as JSON and YAML.
Cons
Translation quality depends on the connected LLM and needs human review.
Requires Node.js and an MCP-compatible client to operate.
Most useful within the MCP ecosystem; limited standalone value.
