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-uuid-version-generator": {
      "name": "uuid-version-generator",
      "description": "Generate RFC 9562 UUIDs — including the modern v6, v7 and v8 that most generators lack — or decode any UUID back to its version, variant and embedded timestamp.",
      "baseUrl": "http://127.0.0.1:3003/mcp/sse?toolId=uuid-version-generator",
      "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": "uuid-version-generator",
    "arguments": {
  "mode": "generate",
  "version": "v5",
  "count": 5,
  "uppercase": false,
  "namespace": "dns",
  "name": "example.com",
  "uuidToDecode": "e.g. 017f22e2-79b0-7cc3-98c4-dc0c0c07398f"
}
  }
}

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).
