file· File resultOpen tool

Quick start

Call this tool from your code in three languages.

cURL

# 1) Upload each file first → returns { filePath }
curl -X POST 'https://api.elysiatools.com/upload/audio-noise-reducer' \
  -F 'file=@/path/to/audioFile.ext'

# 2) Call the tool with the returned filePath values
curl -X POST 'https://api.elysiatools.com/en/api/tools/audio-noise-reducer' \
  -F 'audioFile=/path/to/file.ext' \
  -F 'algorithm=afftdn' \
  -F 'noiseReductionLevel=0.5' \
  -F 'highpassFreq=80' \
  -F 'lowpassFreq=8000' \
  -F 'outputFormat=mp3'

API reference

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

Endpoint

HTTP

Parameters

Name	Type	Required	Description
audioFile	fileupload required	Yes	—
algorithm	select	Yes	—
noiseReductionLevel	range	No	0.1 = light reduction, 1.0 = maximum reduction. Higher values may remove more audio details.

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-audio-noise-reducer": {
      "name": "audio-noise-reducer",
      "description": "Remove background noise from audio files using various noise reduction algorithms",
      "baseUrl": "https://api.elysiatools.com/mcp/sse?toolId=audio-noise-reducer",
      "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": "audio-noise-reducer",
    "arguments": {
  "audioFile": "https://example.com/file.ext",
  "algorithm": "afftdn",
  "noiseReductionLevel": 0.5,
  "highpassFreq": "80",
  "lowpassFreq": "8000",
  "outputFormat": "mp3"
}
  }
}

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).
