file· File resultOpen tool

Quick start

Call this tool from your code in three languages.

cURL
# 1) Request a presigned URL → returns { uploadUrl, storageKey }
curl -X POST 'https://api.elysiatools.com/api/upload/presign/image-trim-tolerance' \
  -H 'Content-Type: application/json' \
  -d '{"filename":"imageFile.ext","contentType":"application/octet-stream","size":12345}'

# 2) PUT the file bytes directly to the presigned uploadUrl
curl -X PUT '<presigned uploadUrl>' \
  --data-binary @/path/to/file.ext

# 3) Call the tool, passing the returned storageKey for each file field
curl -X POST 'https://api.elysiatools.com/en/api/tools/image-trim-tolerance' \
  -F 'imageFile=uploads/2026/01/01/your-tool-1700000000000-abc123.ext' \
  -F 'toleranceMode=absolute' \
  -F 'toleranceValue=40' \
  -F 'autoDetectBackground=true' \
  -F 'backgroundColor=Manual background color (overrides auto-detect)' \
  -F 'scanMethod=full' \
  -F 'edgeSampling=true' \
  -F 'analyzeOnly=false' \
  -F 'format=original' \
  -F 'quality=90'

API reference

Send a POST request with your inputs as JSON. File parameters require a separate upload first.

Endpoint

HTTP
POST https://api.elysiatools.com/en/api/tools/image-trim-tolerance

Parameters

NameTypeRequiredDescription
imageFilefileupload requiredYesUpload any image file (JPEG, PNG, WebP, TIFF) for advanced tolerance trimming
toleranceModeselectYesHow to calculate color tolerance for background detection
toleranceValuerangeNoTolerance for background detection. Higher = more pixels considered background
autoDetectBackgroundcheckboxNoAnalyze image edges to automatically determine the background color
backgroundColorcolorNoSpecific background color to trim (disables auto-detection)
scanMethodselectNoHow to scan the image for content boundaries
edgeSamplingcheckboxNoAdd padding proportional to tolerance to avoid cutting off edge content
analyzeOnlycheckboxNoAnalyze tolerance settings without trimming the image
formatselectNoChoose output format or keep original
qualitynumberNoOutput quality for lossy formats (JPEG, WebP). Higher = better quality but larger file size
File-type parameters must be uploaded first via POST /upload/image-trim-tolerance, then the returned filePath is passed to the corresponding file field.

MCP integration

Add this tool to your Model Context Protocol server so AI agents can list and call it.

Server configuration

Add this block to your MCP client configuration:

mcp.json
{
  "mcpServers": {
    "elysiatools-image-trim-tolerance": {
      "name": "image-trim-tolerance",
      "description": "Advanced image trimming with configurable tolerance levels for precise border removal",
      "baseUrl": "https://api.elysiatools.com/mcp/sse?toolId=image-trim-tolerance",
      "command": "",
      "args": [],
      "env": {},
      "isActive": true,
      "type": "sse"
    }
  }
}

List available tools

After connecting to the SSE endpoint, list the exposed tools:

tools/list
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/list"
}

Call this tool

Invoke the tool by its id, passing arguments built from its parameters:

tools/call
{
  "jsonrpc": "2.0",
  "id": 2,
  "method": "tools/call",
  "params": {
    "name": "image-trim-tolerance",
    "arguments": {
  "imageFile": "https://example.com/file.ext",
  "toleranceMode": "absolute",
  "toleranceValue": 40,
  "autoDetectBackground": true,
  "backgroundColor": "Manual background color (overrides auto-detect)",
  "scanMethod": "full",
  "edgeSampling": true,
  "analyzeOnly": false,
  "format": "original",
  "quality": 90
}
  }
}
Chain multiple tools in one session with a comma-separated toolId list, e.g. /mcp/sse?toolId=png-to-webp,jpg-to-webp,gif-to-webp (max 20).
File parameters accept a public file URL only (https://…). Local paths, data: URIs, and Base64 strings are not supported.
