106 tools. 18 only read. 1 changes records. 10 move money. 77 have no reading.

AI reading, beta. side-effects v1 on claude-haiku-5.5, calibrated on MCP (golden-3). Only readings above a measured precision count. Counts are tools, not calls: no tool was called.

AI readings summary · beta

The service lists 106 tools, and 18 have AI readings.

7 tools are read as moving money, including ai_chat, token_verdict and ai_translate.

token_watch_subscribe is read as creating records.

10 tools are read as read-only, including base_erc20_allowance, optimism_wallet_balances and arbitrum_contract_info.

Written by code from the AI readings on this page: it groups them and says nothing they do not.
