This is especially useful for non-English speakers who want to receive answers in their native language. + +## Configuration + +### 1. Environment Variable + +Set the language using the `LOCALE` environment variable in your `.env` file: + +```bash +# In your .env file +LOCALE=fr-FR +``` + +### 2. Supported Languages + +You can use any standard language code. Examples: + +- `fr-FR` - French (France) +- `en-US` - English (United States) +- `zh-CN` - Chinese (Simplified) +- `zh-TW` - Chinese (Traditional) +- `ja-JP` - Japanese +- `ko-KR` - Korean +- `es-ES` - Spanish (Spain) +- `de-DE` - German (Germany) +- `it-IT` - Italian (Italy) +- `pt-PT` - Portuguese (Portugal) +- `ru-RU` - Russian (Russia) +- `ar-SA` - Arabic (Saudi Arabia) + +### 3. Default Behavior + +If no language is specified (`LOCALE` is empty or unset), tools will default to English. + +## Technical Implementation + +### Architecture + +Localization is implemented in the `BaseTool` class in `tools/shared/base_tool.py`. All tools inherit this feature automatically. + +### `get_language_instruction()` Method + +```python +def get_language_instruction(self) -> str: + """ + Generate language instruction based on LOCALE configuration. + Returns: + str: Language instruction to prepend to prompt, or empty string if no locale set + """ + from config import LOCALE + if not LOCALE or not LOCALE.strip(): + return "" + return f"Always respond in {LOCALE.strip()}.\n\n" +``` + +### Integration in Tool Execution + +The language instruction is automatically prepended to the system prompt of each tool: + +```python +# In tools/simple/base.py +base_system_prompt = self.get_system_prompt() +language_instruction = self.get_language_instruction() +system_prompt = language_instruction + base_system_prompt +``` + +## Usage + +### 1. Basic Setup + +1. Edit your `.env` file: + ```bash + LOCALE=fr-FR + ``` +2. Restart the MCP server: + ```bash + python server.py + ``` +3. Use any tool – responses will be in the specified language. + +### 2. Example + +**Before (default English):** +``` +Tool: chat +Input: "Explain how to use Python dictionaries" +Output: "Python dictionaries are key-value pairs that allow you to store and organize data..." +``` + +**After (with LOCALE=fr-FR):** +``` +Tool: chat +Input: "Explain how to use Python dictionaries" +Output: "Les dictionnaires Python sont des paires clé-valeur qui permettent de stocker et d'organiser des données..." +``` + +### 3. Affected Tools + +All MCP tools are affected by this configuration: + +- `chat` – General conversation +- `codereview` – Code review +- `analyze` – Code analysis +- `debug` – Debugging +- `refactor` – Refactoring +- `thinkdeep` – Deep thinking +- `consensus` – Model consensus +- And all other tools... + +## Best Practices + +### 1. Language Choice +- Use standard language codes (ISO 639-1 with ISO 3166-1 country codes) +- Be specific with regional variants if needed (e.g., `zh-CN` vs `zh-TW`) + +### 2. Consistency +- Use the same language setting across your team for consistency +- Document the chosen language in your team documentation + +### 3. Testing +- Test the configuration with different tools to ensure consistency + +## Troubleshooting + +### Issue: Language does not change +**Solution:** +1. Check that the `LOCALE` variable is correctly set in `.env` +2. Fully restart the MCP server +3. Ensure there are no extra spaces in the value + +### Issue: Partially translated responses +**Explanation:** +- AI models may sometimes mix languages +- This depends on the multilingual capabilities of the model used +- Technical terms may remain in English + +### Issue: Configuration errors +**Solution:** +1. Check the syntax of your `.env` file +2. Make sure there are no quotes around the value + +## Advanced Customization + +### Customizing the Language Instruction + +To customize the language instruction, modify the `get_language_instruction()` method in `tools/shared/base_tool.py`: + +```python +def get_language_instruction(self) -> str: + from config import LOCALE + if not LOCALE or not LOCALE.strip(): + return "" + # Custom instruction + return f"Always respond in {LOCALE.strip()} and use a professional tone.\n\n" +``` + +### Per-Tool Customization + +You can also override the method in specific tools for custom behavior: + +```python +class MyCustomTool(SimpleTool): + def get_language_instruction(self) -> str: + from config import LOCALE + if LOCALE == "fr-FR": + return "Respond in French with precise technical vocabulary.\n\n" + elif LOCALE == "zh-CN": + return "请用中文回答，使用专业术语。\n\n" + else: + return super().get_language_instruction() +``` + +## Integration with Other Features + +Localization works with all other MCP server features: + +- **Conversation threading** – Multilingual conversations are supported +- **File processing** – File analysis is in the specified language +- **Web search** – Search instructions remain functional +- **Model selection** – Works with all supported models diff --git a/providers/openai_compatible.py b/providers/openai_compatible.py index 17ce60d..88cbb26 100644 --- a/providers/openai_compatible.py +++ b/providers/openai_compatible.py @@ -311,11 +311,12 @@ class OpenAICompatibleProvider(ModelProvider): last_exception = None for attempt in range(max_retries): -
