mcp.json

{
  "mcpServers": {
    "elysiatools-chunk-array": {
      "name": "chunk-array",
      "description": "Split array into chunks of specified size using lodash _.chunk",
      "baseUrl": "https://api.elysiatools.com/mcp/sse?toolId=chunk-array",

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": "chunk-array",

  "array": "[1, 2, 3, 4, 5] or [\"a\", \"b\", \"c\", \"d\", \"e\"]",
  "size": 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).
