Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.
get_events reads open 1h ago
The scheduled US market events for a window of days, from the same calendar the FirmTape terminal draws: FOMC decisions, press conferences and minutes, CPI, payrolls, PCE, PPI, GDP, retail sales, JOLTS, ISM, the Fed Chair's speeches, the Beige Book, 10/20/30-year Treasury auctions, mega-cap earnings, monthly and quarterly expiration and early closes. Each event carries its minute in ET, a link to its source, and, where the archive has measured it, what usually follows, what the dealer book did, and for the releases the forecast, the prior and the actual print. Use when: 'what is on the calendar this week', 'when is the next FOMC', 'is there anything at 14:00 today'. Not for: session measurements (get_session) or levels (get_levels). Limits: US only, 2019 to about a year ahead, at most 31 days per call.

How the SPX dealer-positioning levels MOVED across recent finished sessions: the zero-gamma flip, call resistance and put support day by day, each session's change from the one before, and summary statistics for the window (flip range, net drift, mean daily movement, how often price closed above the flip). Use when: the question is about a trend or a window — has the flip been climbing, how far does it travel in a week — instead of calling get_levels once per day. Not for: one day (get_levels / get_session) or anything inside a session (get_gex_profile). ES: pass symbol ES (or MES) for the same series in E-mini prices, each session moved by its own ES basis. Limits: finished sessions only, max 40 per call; days absent from the archive are reported in `missing`, never interpolated. Measurements only — no buy/sell signals, no forecast.

The minutes of one finished SPX session that the tape itself marked as market-moving, with what stood beside each: the scheduled event that owned the minute, the moment two or more public news desks carried an item (timed to the second, labelled by class, never the headline's text), or the honest reading that no headline existed and the dealer book moved on its own. Each minute carries the index move over the next 5 and 15 minutes and the flip at that minute. Use when: 'what moved SPX at 14:25 on 2026-09-10', 'were there news-driven minutes yesterday', 'which afternoon moves had no headline'. Not for: the scheduled calendar itself (get_events) or the day's levels (get_levels). Limits: finished sessions only (the live day is part of the paid live stream), sessions from 2022-04 on, ET clock.

Filter the finished SPX sessions in the FirmTape archive by their closing measurements and count them: regime at the close and at the open, zero-gamma flip crossings, direction and size of the move, net-gamma percentile, 0DTE ATM IV at the open, the calendar event, weekday and year. Returns how many sessions match, two shares over them (closed above the flip, mean absolute move) printed next to the same shares over the whole archive, and the matched days. A matched share close to the archive's share is a base rate, not a pattern. Use when: 'how often did FOMC days close in negative gamma', 'the days that closed below the flip with the percentile under 20', 'largest moves on CPI days since 2024'. Not for: one day's numbers (get_session), gamma by strike (get_gex_profile), or testing a rule with out-of-sample statistics (the Lab). Limits: counts over finished sessions' closing measurements only, no per-strike data; at most 50 sessions listed per call. Counts, not investment advice.

Search FirmTape for documents about SPX dealer positioning: the explainer pages, the dated research measurements, and the archive of finished trading sessions. Returns ids to pass to `fetch`. A date in the query ("2026-08-24", "August 24 2026", "August 2026") finds the session or sessions for it. Clients that can call the specific tools should prefer list_sessions / get_session / get_levels / get_level_history / screen_sessions instead — those return structured numbers rather than documents. Not for: fetching a document you already have the id for (`fetch`) or any measurement you can name a date for. Limits: FirmTape's own public pages and finished sessions only, ranked by keyword — it searches no other site.

What the free FirmTape SPX archive holds: the first and last finished session, how many sessions, and the NYSE trading days in that span that are MISSING from it (weekdays minus US market holidays; early closes count as trading days), optionally inside a from/to window. Use when: 'is 2024-03-15 in the archive', 'how complete is 2023', 'which days are missing' before a study that needs every session. Not for: the newest days themselves (list_sessions) or any measurement (get_session). Limits: the trading calendar covers 2022 to 2026; missing days are reported, never filled in.

The latest dealer gamma picture for a symbol OTHER than the SPX archive: index, ETF and stock option chains (for example QQQ, SPY, IWM, NDX, RUT, NVDA, TSLA, GLD, TLT), and the E-mini futures ES and NQ (MES, MNQ): ES/NQ are the SPX/NDX books moved by the day's basis (future minus index, from put-call parity on the index options; no CME data). Returns spot, the zero-gamma flip, call and put walls and net gamma for the VOLUME book and the OPEN_INTEREST book, the heaviest strikes, a per-expiry table and a trust grade. Use when: the question is about a ticker's gamma exposure, flip or walls right now or at the last close, including ES or NQ gamma levels. Not for: SPX or ES history or a past date (get_session, get_levels, get_gex_profile, which take symbol ES for past days); anything inside a past session. Limits: latest snapshot only (rebuilt every few minutes in session hours); calls count as dealer-long and puts as dealer-short, which is a convention, not a measurement, and on single stocks it is an approximation (see trust.grade: A and B are indices and ETFs, C and D single stocks). Units: US dollars of dealer delta per 1% move.

List the finished SPX trading sessions in the free FirmTape archive, newest first, with the total count and how far back coverage runs. Every listed day can be fetched with get_session / get_levels and replayed free at FirmTape. Use when: you need to know which days exist, or the size and span of the archive, before asking about one. Not for: any measurement about a day — call get_session with that date instead. Limits: finished sessions only (today's session appears after the close), max 50 days per call.

Only the dealer-positioning level set for one finished SPX session: zero-gamma flip, call resistance, put support, plus where the session closed relative to them. A strict subset of get_session. Use when: the levels are the whole question and the rest of the session would be noise. Not for: OHLC, flip crossings, net-gamma percentile or ATM IV (get_session); more than one day (get_level_history); gamma by strike (get_gex_profile). ES: pass symbol ES (or MES) for ES gamma levels, the SPX levels moved by the day's ES basis (future minus index from put-call parity; no CME data); NQ levels come from get_symbol_gamma. Limits: finished sessions only, one day per call.

The SPX dealer gamma LADDER for one minute of a finished session: gamma by strike around spot, the level set, and the heaviest strikes. Read by default as the VOLUME book, the one the terminal's chart draws; also as the MEASURED book (signed off the trade tape, FirmTape's own read) or the OPEN_INTEREST convention every other public GEX chart draws — the same minute through three lenses. The level set is the volume book's whichever ladder is read. Use when: the question is about SHAPE — where gamma sits, how heavy a wall is, how far the three conventions disagree — or about one moment inside a session rather than the day as a whole. Not for: a day's headline numbers (get_session), the level set alone (get_levels), or movement across days (get_level_history). ES: pass symbol ES (or MES) for ES strikes, the SPX ladder moved by the ES basis at the frame's minute. Limits: finished sessions only, one frame every 5 minutes (a requested minute snaps back to the frame at or before it), published window ±2.5% of spot; the three books are not comparable in magnitude. Measurements only, no buy/sell signals.

Everything FirmTape measured for ONE finished SPX session: OHLC and VWAP, the zero-gamma flip and how often price crossed it, call/put walls, net-gamma percentile, ATM IV at the open. Use when: you want a whole day in a single call. Not for: the level set alone (get_levels returns the same day, narrower), how the levels moved across days (get_level_history), or gamma by strike (get_gex_profile). ES: pass symbol ES (or MES) for the same day in E-mini prices, the SPX book moved by the day's ES basis. Limits: finished sessions only, one day per call. Measurements only — FirmTape deliberately publishes no buy/sell signals.

A FirmTape URL or a bare YYYY-MM-DD trading day is accepted too. Use when: you hold an id from `search`, or a client that only speaks search/fetch (ChatGPT).

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.
Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.
- Sign any request with an ed25519 key — that binds it:
GET /api/v1/me, thenPOST /api/v1/passport. - Prove it is yours. Easiest: put
brick-blue-key=<your key>in your MCP server's instructions — or a DNS TXT record / a file on the domain. - Ask the hub to check:

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.
An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
