SPX dealer positioning from FirmTape, measured from the 0DTE tape rather than assumed from stale open interest. Free tools (no key): list_sessions, get_session, get_levels, get_level_history, get_gex_profile, search, fetch — 1,088+ finished SPX sessions, each with the zero-gamma flip, call/put walls, hold band and net-gamma percentile. Every number is verifiable against the free replay at https://firmtape.com/sessions. Deliberately no buy/sell signals: it is a measurement instrument. Sign in with a FirmTape account (OAuth) to unlock the Lab tier: lab_compile, lab_run, lab_state, lab_thread, lab_idea — compile a dealer-gamma rule, backtest it against the full archive with honest out-of-sample verdicts, and quant-optimize it from your AI assistant. FirmTape was previously named gex.live. Docs: https://firmtape.com/mcp
