## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-09-29.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 77/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 3582 tokens (~298/item across 12 items; 12 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 97/100
  - Stability observed for 29 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
  - Structured output schemas are declared (67% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 12 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 13 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

## MCP tools (12)

### `get_market_moving_minutes` (~253 tokens)

Minutes that moved the tape

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 and expected-hold band 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.

Input parameters:

- `day` (string): The session, YYYY-MM-DD (default: the last finished session)
- `tape_only` (boolean): Only minutes the tape confirmed (default true; false adds the flashes the tape ignored and the calendar events it did not react to)

Output parameters:

- `day` (string): Trading day, YYYY-MM-DD
- `minutes` (array): The marked minutes of the session in clock order
- `summary` (string): One sentence carrying this answer's numbers, its trading day and its source, written to be quoted verbatim to a reader rather than paraphrased.

### `get_events` (~272 tokens)

Market calendar

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.

Input parameters:

- `from` (string): First day, YYYY-MM-DD (default today, ET)
- `impact` (string): Lowest impact to include (default med: high and medium)
- `to` (string): Last day, YYYY-MM-DD (default from + 6 days; at most 31 days)

Output parameters:

- `events` (array): Scheduled US market events in the window, in date and time order
- `from` (string): Trading day, YYYY-MM-DD
- `summary` (string): One sentence carrying this answer's numbers, its trading day and its source, written to be quoted verbatim to a reader rather than paraphrased.
- `to` (string): Trading day, YYYY-MM-DD

### `list_sessions` (~139 tokens)

List sessions

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.

Input parameters:

- `limit` (integer): How many days to return (default 10, max 50)

Output parameters:

- `newest` (array): Trading days, newest first
- `summary` (string): One sentence carrying this answer's numbers, its trading day and its source, written to be quoted verbatim to a reader rather than paraphrased.
- `total_sessions` (integer): How many finished sessions the free archive holds

### `screen_sessions` (~673 tokens)

Screen sessions

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, whether the expected-hold band held, 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, three shares over them (closed above the flip, band held, 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 the band broke 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.

Input parameters:

- `band` (string): Whether the expected-hold band held all session
- `cross` (string): Flip crossings in the session: 0 = none, 1 = exactly one, 2 = two or more
- `dir` (string): Direction of the open-to-close move
- `dow` (string): Day of the week
- `event` (string): Event the day carried: fomc (decision days), cpi, nfp (payrolls), pce, ppi, gdp, retail (retail sales), jolts, ism, claims, auctions (Treasury), fed (speeches, Beige Book), opex (expiration), vix (VI…
- `gpct` (string): Net-gamma percentile at the close: under 20, 20 to 50, 50 to 80, 80 and above
- `iv` (string): 0DTE ATM implied vol at the open: under 10%, 10-15%, 15-20%, 20% and above
- `limit` (integer): How many matched sessions to list (default 20, max 50); the counts always cover every match
- `move` (string): Size of the open-to-close move: under 0.5%, 0.5% or more, 1% or more, 2% or more
- `open` (string): Regime at the open: pos = opened above the flip, neg = below
- `regime` (string): Regime at the close: pos = closed above the zero-gamma flip, neg = below
- `sort` (string): Order of the sessions list: newest (default), oldest, move (largest absolute move first), gpct (highest percentile first)
- `year` (string): Calendar year, e.g. 2025; a year outside the archive is dropped

Output parameters:

- `archived` (integer): Finished sessions in the archive
- `filters` (object): The filters the screener accepted; a value outside the vocabulary is dropped, not an error
- `label` (string): The filters in words
- `matched` (integer): Sessions matching every filter
- `question_url` (string): When the filters are one of the screener's common questions, that question's own page (e.g. /screener/negative-gamma-closes), the address to cite
- `screened` (integer): Sessions whose closing measurements were available to screen
- `sessions` (array): Matched sessions in the requested order (default newest first), at most `limit`
- `shares` (object): The same three shares over the matched sessions and over the whole archive; a matched share close to the archive's is a base rate, not a pattern
- `source` (string)
- `summary` (string): One sentence carrying this answer's numbers, its trading day and its source, written to be quoted verbatim to a reader rather than paraphrased.
- `truncated` (boolean): True when more sessions matched than `sessions` carries
- `url` (string): The /screener page that shows the same result to a person

### `get_session` (~168 tokens)

Session summary

Everything FirmTape measured for ONE finished SPX session: OHLC and VWAP, the zero-gamma flip and how often price crossed it, call/put walls, the hold band, 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). Limits: finished sessions only, one day per call. Measurements only — FirmTape deliberately publishes no buy/sell signals.

Input parameters:

- `day` (string, required): A finished trading day, YYYY-MM-DD. Weekends, holidays and days before coverage return an error — call list_sessions to see which days exist.

Output parameters:

- `day` (string): Trading day, YYYY-MM-DD
- `dealer_positioning` (object)
- `events` (array): The day's scheduled market events (high and medium impact), each with its minute in ET, its source, the release's prints when known, and, for an event inside the session, what the book did in the 15…
- `replay` (string): Free minute-by-minute replay of the session on FirmTape
- `session` (object): SPX price facts for the session
- `summary` (string): One sentence carrying this answer's numbers, its trading day and its source, written to be quoted verbatim to a reader rather than paraphrased.

### `get_level_history` (~253 tokens)

Level history

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). 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.

Input parameters:

- `days` (integer): How many of the most recent finished sessions to read (default 20, max 40). Ignored when `from` is given.
- `from` (string): Start of an explicit window, YYYY-MM-DD (inclusive). Overrides `days`.
- `to` (string): End of an explicit window, YYYY-MM-DD (inclusive). Defaults to the newest finished session.

Output parameters:

- `from` (string): Trading day, YYYY-MM-DD
- `missing` (array): Days in the requested window with no payload in the archive; the window is reported over what was actually read
- `movement` (object): How the level set travelled across the window. Descriptive statistics, not a forecast.
- `sessions` (array): One entry per finished session, NEWEST FIRST, same order as list_sessions
- `summary` (string): One sentence carrying this answer's numbers, its trading day and its source, written to be quoted verbatim to a reader rather than paraphrased.
- `to` (string): Trading day, YYYY-MM-DD

### `get_symbol_gamma` (~273 tokens)

Gamma for another symbol

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). 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. Not for: SPX history, a past date, or the tape-signed measured book (get_session, get_levels, get_gex_profile); 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.

Input parameters:

- `symbol` (string, required): The ticker. Carried symbols are listed at https://firmtape.com/gex; an unknown ticker returns an error naming that page.

### `get_levels` (~156 tokens)

Level set

Only the dealer-positioning level set for one finished SPX session: zero-gamma flip, call resistance, put support, hold band — 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). Limits: finished sessions only, one day per call.

Input parameters:

- `day` (string, required): A finished trading day, YYYY-MM-DD. Weekends, holidays and days before coverage return an error — call list_sessions to see which days exist.

Output parameters:

- `close` (number|null): Session close
- `close_minus_flip` (number|null): Close minus zero-gamma flip, index points; positive = closed above the flip
- `day` (string): Trading day, YYYY-MM-DD
- `levels` (object): Dealer-positioning levels in SPX index points; null when the session did not produce one
- `replay` (string): Free minute-by-minute replay of the session on FirmTape
- `summary` (string): One sentence carrying this answer's numbers, its trading day and its source, written to be quoted verbatim to a reader rather than paraphrased.

### `get_gex_profile` (~384 tokens)

Gamma by strike

The SPX dealer gamma LADDER for one minute of a finished session: gamma by strike around spot, the level set, and the heaviest strikes. Readable as the MEASURED book (signed off the trade tape, FirmTape's own read), as the OPEN_INTEREST convention every other public GEX chart draws, or as the VOLUME convention — the same minute through three lenses. 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). 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.

Input parameters:

- `book` (string): Which book to read (default measured). open_interest is the convention rival tools print.
- `day` (string, required): A finished trading day, YYYY-MM-DD. Call list_sessions if unsure which days exist.
- `expiry_scope` (string): all = every expiry the session's book was pulled with (default); 0dte = the same-day slice alone
- `minute` (string): ET minute HH:MM inside 09:30-16:00. Snaps back to the frame at or before it, so quote the minute the answer returns. Default: the last frame of the session.
- `strikes_around_spot` (integer): How many strikes to return each side of spot (default 20). Raise it for the whole published window, which is +/-2.5% of spot.

Output parameters:

- `book` (string): Which book was read: measured, open_interest or volume
- `book_note` (string): How this book is built, and what it can and cannot be compared with
- `day` (string): Trading day, YYYY-MM-DD
- `expiry_scope` (string): all = every expiry this session's book was pulled with; 0dte = the same-day slice alone
- `heaviest` (array): The largest strikes by absolute gamma inside the window, heaviest first
- `levels` (object): Dealer-positioning levels in SPX index points; null when the session did not produce one
- `minute` (string): The ET minute (HH:MM) this profile actually belongs to. The archive keeps a frame every 5 minutes, so a requested minute snaps back to the frame at or before it — quote the minute returned here, not…
- `net_gamma_in_window` (number|null): Sum of the returned strikes — a window total, not the session's net gamma
- `replay` (string): Free minute-by-minute replay of the session on FirmTape
- `spot` (number|null): SPX at that minute
- `strikes` (array): Dealer gamma by strike at that minute, lowest strike first
- `strikes_returned` (integer): How many strikes the window actually held
- `summary` (string): One sentence carrying this answer's numbers, its trading day and its source, written to be quoted verbatim to a reader rather than paraphrased.
- `unit` (string): Unit of every gamma number below

### `search` (~178 tokens)

Search FirmTape

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.

Input parameters:

- `query` (string, required): A topic, a question, or a trading date

### `fetch` (~155 tokens)

Fetch a FirmTape document

Retrieve the full text of one FirmTape document by the id `search` returned: `session:YYYY-MM-DD` for a finished trading session, `page:/path` for an explainer or research page. 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). Not for: structured numbers — get_session and get_levels answer the same day with fields instead of prose. Limits: public FirmTape documents only; long pages are truncated with a link to the rest.

Input parameters:

- `id` (string, required): An id from `search`, a FirmTape URL, or a YYYY-MM-DD trading day

### `options_strategy_test` (~423 tokens)

Test an options strategy on the archive

Test an SPX 0DTE options strategy — a condor, strangle, straddle or any leg set — against every session in the FirmTape archive on real quotes and real settlement. One call prices it 63 ways: seven widths of your geometry across nine entry times, so the answer is WHERE TO PUT THE STRIKES rather than a verdict on one guess. Short legs are sold at the bid and long legs bought at the ask, $1.25 a leg — measured on 13.1M prints, the median SPX 0DTE print pays the full quoted half-spread, so these fills are the median outcome and not a conservative one. Returns the marginal by width and by entry, a recommended direction ONLY when the marginal is ordered and a withheld holdout agrees, the day-clustered mean and its error, prob_loss_20, and all 63 cells with yours marked. If those 63 come back flat the run carries on by itself for the same credits -- where the structure sits relative to spot, past the edge of the grid, then eight standard 0DTE shapes -- up to 154 configurations, so the answer is 'not this, and here is what the archive does pay for' rather than a shrug. It never names a best cell: the best of 63 is best by chance. Spends 10 credits, refunded on failure. Requires a Lab token (Authorization header).

Input parameters:

- `entry` (string): Your entry time. All nine are reported whatever you pick; this only marks which cell is yours.
- `legs` (array, required): The strategy, as legs. `dist` is the leg's distance from spot as a fraction: -0.005 is half a percent below, +0.0083 is 0.83% above. Strikes are not given because they travel — the geometry is what t…
