Shows the camera, lens and exposure details, and keeps or removes the EXIF metadata as you prefer.\n\nMethodology:\n- The file type is detected from its content: HEIC/HEIF and AVIF by their ISO-BMFF brand, RAW by its TIFF/ORF/RW2/RAF/CR3 signature (for TIFF-based RAW such as NEF/ARW the file extension decides between RAW and plain TIFF).\n- HEIC/HEIF and AVIF are decoded with libheif (heif-convert/heif-dec), which applies the rotation and mirroring stored in the file. RAW files are developed with LibRaw (dcraw_emu): demosaicing (AHD), camera or automatic white balance, sRGB output, 8 bits per channel.\n- ImageMagick encodes JPG/PNG; WebP is encoded with libwebp (cwebp) when installed. Width, height and pixel count are checked before decoding (limit 100 megapixels).\n- With \"Keep EXIF\" on, exiftool copies EXIF/XMP/IPTC from the original into the new file (without embedded previews) and resets the Orientation tag when the pixels were rotated. Otherwise the output carries no metadata at all.\n- RAW development here is a neutral default rendering. A dedicated RAW editor (Lightroom, darktable, RawTherapee) gives more control over exposure, noise and colour.\n\nKeep your original HEIC/RAW file: converting to JPG or WebP discards detail and dynamic range.", "tags": [ "media" ], "x-mcp-tool": "heic_raw_converter", "requestBody": { "required": true, "content": { "application/json": { "schema": { "$ref": "#/components/schemas/HeicRawConverterInput" }, "examples": { "example1": { "summary": "AVIF photo to JPG", "value": { "file": { "filename": "photo.avif", "contentType": "image/avif", "contentBase64": "AAAAIGZ0eXBhdmlmAAAAAGF2aWZtaWYxbWlhZk1BMUEAAADybWV0YQAAAAAAAAAoaGRscgAAAAAAAAAAcGljdAAAAAAAAAAAAAAAAGxpYmF2aWYAAAAADnBpdG0AAAAAAAEAAAAeaWxvYwAAAABEAAABAAEAAAABAAABGgAAAC0AAAAoaWluZgAAAAAAAQAAABppbmZlAgAAAAABAABhdjAxQ29sb3IAAAAAamlwcnAAAABLaXBjbwAAABRpc3BlAAAAAAAAABAAAAAMAAAAEHBpeGkAAAAAAwgICAAAAAxhdjFDgSAAAAAAABNjb2xybmNseAABAAIABoAAAAAXaXBtYQAAAAAAAAABAAEEAQKDBAAAADVtZGF0EgAKCDgM/thAQIGkMh8YAAooooQAxC02adqijwo4ID0p6Pgn+VaHUuOCSvH4" }, "format": "jpeg", "quality": 85 } } } } } }, "responses": { "200": { "description": "Calculation result envelope.", "content": { "application/json": { "schema": { "$ref": "#/components/schemas/HeicRawConverterResult" } } } }, "400": { "description": "Malformed JSON body.", "content": { "application/problem+json": { "schema": { "$ref": "#/components/schemas/Problem" } } } }, "422": { "description": "Invalid input (see errors[]).", "content": { "application/problem+json": { "schema": { "$ref": "#/components/schemas/Problem" } } } }, "429": { "description": "Rate limit exceeded (see Retry-After).", "content": { "application/problem+json": { "schema": { "$ref": "#/components/schemas/Problem" } } } } } } }, "/api/v1/tool": { "get": { "operationId": "getToolDefinition", "summary": "Inputs, output schema and examples for this tool", "responses": { "200": { "description": "Tool definition.", "content": { "application/json": { "schema": { "type": "object" } } } } } } } }, "components": { "schemas": { "Problem": { "type": "object", "description": "RFC 9457 problem details. 422 responses include per-field `errors`.", "required": [ "type", "title", "status", "detail" ], "properties": { "type": { "type": "string" }, "title": { "type": "string" }, "status": { "type": "integer" }, "detail": { "type": "string" }, "code": { "type": "string" }, "errors": { "type": "array", "items": { "type": "object", "required": [ "field", "message" ], "properties": { "field": { "type": "string" }, "message": { "type": "string" } } } } } }, "HeicRawConverterInput": { "type": "object", "additionalProperties": false, "properties": { "file": { "title": "HEIC, AVIF or RAW photo", "description": "HEIC/HEIF (iPhone), AVIF or camera RAW (CR2, CR3, NEF, ARW, DNG, ORF, RW2, RAF, PEF…), max 50 MB and 100 megapixels.
