Withings MCP Server

# Release v1.1.5 **Release Date:** 2025-12-25 ## 🌍 New Feature: Automatic Timezone Conversion ### All Timestamps Now in Local Time **What's New:** All date and time fields in API responses are now automatically converted from UTC to your local timezone. **Why This Matters:** - 🕒 No more UTC confusion - timestamps match your local time - 📅 Better readability for LLMs and humans - 🌐 ISO 8601 format with timezone information (e.g., `2025-12-25T14:30:00+01:00`) ## Changes ### Automatic Timezone Conversion **What Changed:** The server now automatically converts all UTC timestamps returned by the Withings API to your local timezone before returning them. **Affected Fields:** - `date` - Measurement and activity timestamps - `startdate` / `enddate` - Period boundaries - `start` / `end` - Sleep and workout periods - `created` / `modified` / `lastupdate` - Metadata timestamps **Format:** All converted timestamps use ISO 8601 format with timezone: - Before: `1735134600` (Unix timestamp in UTC) - After: `2025-12-25T14:30:00+01:00` (ISO 8601 with local timezone) ### Technical Details Modified `src/withings_mcp_server/server.py`: 1. Added `timezone` import from `datetime` module 2. Added `_convert_utc_to_local()` method for recursive timestamp conversion 3. Applied conversion to all tool responses before returning results 4. Preserves original data structure while converting timestamp fields ## Impact - ✅ Better timestamp readability for LLMs - ✅ Automatic conversion - no configuration needed - ✅ All date fields include timezone information - ✅ Compatible with existing code - ✅ No breaking changes - timestamps are still parseable ## Upgrade Instructions Update to the latest version: ```bash pip install --upgrade withings-mcp-server ``` Or if installed in editable mode: ```bash cd /path/to/withings-mcp-server git pull ``` Then restart Claude Desktop. ## Notes - The conversion uses your system's local timezone - Input dates (in requests) still accept both YYYY-MM-DD and Unix timestamps - The Withings API still receives UTC timestamps - conversion only affects responses
