Add this block to your MCP client configuration:

mcp.json

{
  "mcpServers": {
    "elysiatools-config-file-semantic-diff": {
      "name": "config-file-semantic-diff",
      "description": "Compare JSON, YAML, TOML, and dotenv configurations by key path while ignoring ordering and formatting noise.",
      "baseUrl": "https://api.elysiatools.com/mcp/sse?toolId=config-file-semantic-diff",
      "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": "config-file-semantic-diff",
    "arguments": {
  "leftConfig": "{\"server\":{\"port\":8080,\"tags\":[\"api\",\"web\"]}}",
  "leftFormat": "json",
  "rightConfig": "server:\n  tags: [api, web]\n  port: 9090\n",
  "rightFormat": "yaml"
}
  }
}

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).
