Where the tokens are

tool tokens share description schema
hf_whoami 1,948 41.5% 30 26
hf_fs 1,924 41.0% 966 87
hub_repo_details 453 9.7% 76 327
hub_repo_search 364 7.8% 38 278

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/huggingface/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.
