exif-mcp
An MCP server that allows LLMs (or humans) to read image metadata on-demand, entirely offline. Based on the excellent exifr library it's exremely fast and does not rely on any external tools.
Usecases:
- Analyze image metadata and visualize it
- Perform analysis of your image library: what are my most used cameras? Lens distribution? Which dates of the week I take most pictures on? Most favorite locations?
- Debugging image manipulation code.
Ths tool is used extensively by the reverse geolocation service PlaceSpotter for development and testing.

This allows this service to parse image metadata without executing any external tools which allows it to be both highly efficient and secure.

- Multiple segments: Extracts EXIF, GPS, XMP, ICC, IPTC, JFIF, and IHDR metadata
- Various input formats: Supports JPEG, TIFF, HEIC/AVIF, and PNG
- Flexible image sources: Read from file system, URLs, base64 data, or buffers
- Specialized tools: Get orientation, rotation info, GPS coordinates, and thumbnails
