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-integer-to-ipv6": {
      "name": "integer-to-ipv6",
      "description": "Convert integers (128-bit) to IPv6 addresses. Supports batch conversion.",
      "baseUrl": "https://api.elysiatools.com/mcp/sse?toolId=integer-to-ipv6",
      "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": "integer-to-ipv6",
    "arguments": {
  "integerInput": "Enter integers to convert, one per line:\n42540766411282592856906245548098263284\n1\n42540766411282592856903984951653826561\n\nSupports decimal or hexadecimal (0x prefix):\n0x20010db885a3000000008a2e03707334",
  "format": "compressed",
  "addLineNumbers": false,
  "showSourceData": false
}
  }
}

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).
