Invoke the tool by its id, passing arguments built from its parameters:

tools/call

{
  "jsonrpc": "2.0",
  "id": 2,
  "method": "tools/call",
  "params": {
    "name": "venn-diagram-maker",
    "arguments": {
  "setsData": "{\n  \"sets\": [\n    { \"name\": \"Search\", \"size\": 30 },\n    { \"name\": \"Filters\", \"size\": 25 },\n    { \"name\": \"Export\", \"size\": 20 }\n  ],\n  \"intersections\": {\n    \"Search+Filters\": 10,\n    \"Search+Export\": 6,\n    \"Filters+Export\": 5,\n    \"Search+Filters+Export\": 2\n  }\n}",
  "chartTitle": "Feature Adoption",
