Where the tokens are

tool tokens share description schema
discover 347 35.5% 38 281
search_engine_batch 191 19.5% 17 142

scrape_as_markdown 115 11.8% 37 43

Each tool is tokenized on its own, so the parts do not sum exactly to the whole: the array adds its own brackets and commas, and the tokenizer merges tokens across object boundaries. The badge number is always the count of the whole array, never a sum of parts.

Re-derive it

npx -y mcp-context-cost verify results/bright-data/measurement.json

That re-tokenizes the published capture and checks the count and the hash. If it disagrees with the badge, the badge is wrong — open an issue and it gets corrected.
