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": "array-filter",

  "includeUndefined": false,
  "caseSensitive": true,
  "trimWhitespace": true,
  "customSeparator": "Enter separator (default: comma, semicolon, or newline)"
