Localize MCP Server
Open-source MCP server for the Localize Elixir library that teaches AI agents the full Localize API through eleven typed tool calls backed by BEAM introspection. Replaces source-code grepping with structured discovery, documentation, schema, locale resolution, and live execution tools. Supports formatting numbers, currencies, dates, times, units, lists, messages, collation, and plural rules across locales. The server runs locally from the user's project using stdio transport and sees the exact Localize version pinned in mix.exs. Compatible with Claude Desktop, Claude Code, Codex CLI, ChatGPT, and Zed. Published on Hex as localize_mcp. Released July 15, 2026.

Use Cases
| 01 | Teach AI coding agents the full Localize API surface so they can correctly format numbers, currencies, dates, and messages across locales without grepping source code or burning tokens on documentation searches |
| 02 | Enable AI assistants to invoke read-only Localize functions live from within an Elixir project, validating locale resolution and formatting output in real time under timeout and heap safety constraints |
| 03 | Integrate with Claude Code, Cursor, or Zed to provide version-accurate Localize documentation and examples including guided sigil, Gettext, Phoenix, and LiveView translation setup workflows |
