Quick start

Call this tool from your code in three languages.

cURL

curl -X POST 'https://api.elysiatools.com/en/api/tools/text-similarity-detector' \
  -H 'Content-Type: application/json' \
  -d '{"text1":"Enter the first text to compare...","text2":"Enter the second text to compare...","algorithm":"combined","caseSensitive":false,"ignoreWhitespace":true,"minWordLength":2}'

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/text-similarity-detector

Parameters

Name	Type	Required	Description
text1	textarea	Yes	—
text2	textarea	Yes	—
algorithm	select	Yes	—
caseSensitive	checkbox	No	Treat uppercase and lowercase as different characters
ignoreWhitespace	checkbox	No	Remove extra spaces, tabs, and newlines before comparison

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-text-similarity-detector": {
      "name": "text-similarity-detector",
      "description": "Calculate similarity percentage between two texts using multiple algorithms including Cosine Similarity, Jaccard Similarity, and Levenshtein Distance",
      "baseUrl": "https://api.elysiatools.com/mcp/sse?toolId=text-similarity-detector",
      "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": "text-similarity-detector",
    "arguments": {
  "text1": "Enter the first text to compare...",
  "text2": "Enter the second text to compare...",
  "algorithm": "combined",
  "caseSensitive": false,
  "ignoreWhitespace": true,
  "minWordLength": 2
}
  }
}

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).
