AI-powered translation for 48 languages with context-aware quality
Most developer tooling work still happens through a UI a human drives. I18n MCP server moves it into the conversation instead. AI-powered translation for 48 languages with context-aware quality.
Professional translation service client for Claude, Cursor, VS Code, Antigravity, and other AI IDEs using the Model Context Protocol (MCP).
The server publishes 7 tools. What each one is for:
Publishing — Use the publishing script with built-in test gate: bash ./scripts/publish-mcp-client.sh --dry-run # Preview package ./scripts/publish-mcp-client.sh #translate_text — Translate text content with cultural adaptation and context awarenesstranslate_file — The translate_file tool exposed by this serveranalyze_content — Analyze content for translation readiness and get improvement suggestions before translation. This helps identify potential issues and optimizelist_supported_languages — The list_supported_languages tool exposed by this serverget_credits — Check remaining translation credits and word count estimatescheck_translation_status — The check_translation_status tool exposed by this serverBecause this one is hosted, setup is mostly authentication — you point your client at the endpoint and approve access. Nothing runs on your machine, so there is no runtime to keep patched.
Configuration is passed through the environment: MCP_SERVER_URL, I18N_AGENT_API_KEY. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. I18n's toolset — Publishing, translate_text, translate_file and 4 more — is a fair guide to whether it matches your workflow. It is maintained by ai.i18nagent; worth a glance at recent repository activity before you build anything load-bearing on it.
This entry was verified against I18n's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.
| Tool | What it does |
|---|---|
| Publishing | Use the publishing script with built-in test gate: bash ./scripts/publish-mcp-client.sh --dry-run # Preview package ./scripts/publish-mcp-client.sh # Run pre-publish checks npm publish # Publish to npm |
| translate_text | Translate text content with cultural adaptation and context awareness. |
| translate_file | The translate_file tool exposed by this server. |
