## 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 2026-09-21.

- **Endpoint Security**: 83/100
  - 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 is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC is configured correctly; the domain's records validate against the full chain to the root.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 70/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 3062 tokens (~127/item across 24 items; 24 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 100/100
  - No destabilizing schema changes in the last 30 days.
- **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.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 24 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 25 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 (24)

### `get_rates_and_curve` (~70 tokens)

Treasury yields and the curve regime

US Treasury yields, the 2s10s and other spreads, and the curve regime (bull or bear, steepener or flattener) with the time it flipped. Prices are live on Pro and Ultimate, one hour behind on Starter, and answer with upgrade steps on the free tiers.

### `get_curve_history` (~74 tokens)

Curve regime flips

Past curve regime changes: every flip with its time, what it flipped from, and how the session closed.

Input parameters:

- `limit` (integer): Most rows to return.
- `since` (string): Oldest date to include, like 2026-06-01. How far back you can go depends on your plan.

### `get_fx_board` (~83 tokens)

FX momentum board

FX momentum scorecard: seven major currencies scored against the basket. Newest reading plus past boards. Market data: answers with numbers on Pro and Ultimate.

Input parameters:

- `limit` (integer): Most rows to return.
- `since` (string): Oldest date to include, like 2026-06-01. How far back you can go depends on your plan.

### `get_vol_board` (~88 tokens)

Volatility board

Implied volatility board: VIX and the other vol gauges with their one-year percentile. Newest reading plus past boards. Market data: answers with numbers on Pro and Ultimate.

Input parameters:

- `limit` (integer): Most rows to return.
- `since` (string): Oldest date to include, like 2026-06-01. How far back you can go depends on your plan.

### `get_inflation` (~184 tokens)

Inflation

Every US inflation measure on one axis: headline and core CPI and PCE, supercore, the trimmed means, the median, the sticky and flexible splits, the CPI components, and what markets expect next. Each one comes back with its year-over-year reading plus 1, 3 and 6-month annualised, so you never have to annualise anything yourself. Also says which parts of the basket are driving the headline rate. `measures` filters by key, `history` adds the monthly series. Published statistics, so it answers on every tier.

Input parameters:

- `history` (boolean): Add the full monthly series per measure.
- `measures` (string): Comma-separated keys to return, such as core_cpi,core_pce. Omit for all of them.
- `window` (integer): Months of history to include when history is true.

### `get_jobs` (~212 tokens)

Jobs

Every US employment measure on one axis: total nonfarm payrolls split into private and government, the ten private sectors, federal, state and local government, ADP's own private count by sector, initial and continuing jobless claims, and JOLTS openings, hires, quits and layoffs including openings by sector. Each comes back with its monthly change plus 3, 6 and 12-month windows, in THOUSANDS of jobs. Also says which sectors drove the headline, and those parts sum to it exactly. Percentages such as the unemployment and quits rates ride in `standing`. `measures` filters by key, `history` adds the monthly series. Published statistics, so it answers on every tier.

Input parameters:

- `history` (boolean): Add the full monthly series per measure.
- `measures` (string): Comma-separated keys to return, such as payrolls,edhealth,openings. Omit for all.
- `window` (integer): Months of history to include when history is true.

### `get_rate_path` (~215 tokens)

Rate path

What the market is paying for US interest rates up to four years out. Two strips, kept apart because they are DIFFERENT RATES: `sr3` is sixteen quarterly 3-month SOFR futures grouped into the whites, reds, greens and blues a rates desk quotes, and `ff` is forty-eight monthly 30-day fed funds contracts. Every contract carries its implied rate now and the rate the SAME contract carried six and twelve months ago, so the gap is the market changing its mind rather than a different instrument. Rates are percent. These are traded prices and not forecasts. Do not compare the two lanes contract by contract: SOFR is secured and the fed funds effective rate is not, and an SR3 month spans the quarter between two IMM dates while a fed funds month is a calendar month.

Input parameters:

- `history` (boolean): Add each contract's own daily settlement run.
- `lane` (string): sr3 for the quarterly SOFR strip, ff for the monthly fed funds strip. Omit for both.

### `get_correlations` (~95 tokens)

Cross-asset correlation matrix (stocks, bonds, dollar, gold, oil) over 30 to 120 day windows. Newest reading plus past boards. Market data: answers with numbers on Pro and Ultimate.

Input parameters:

- `limit` (integer): Most rows to return.
- `since` (string): Oldest date to include, like 2026-06-01. How far back you can go depends on your plan.

### `get_hormuz_transits` (~47 tokens)

Strait of Hormuz transits

Ships through the Strait of Hormuz per day, split tanker and cargo, measured by Helious from live ship tracking.

Input parameters:

- `days` (integer): How many days back.

### `get_yield_closes` (~79 tokens)

Official 17:00 Treasury closes

Official 17:00 New York Treasury yield closes per session, as Helious recorded them. Opens on Starter and above.

Input parameters:

- `limit` (integer): Most rows to return.
- `since` (string): Oldest date to include, like 2026-06-01. How far back you can go depends on your plan.

### `get_economic_calendar` (~157 tokens)

Economic calendar

Economic releases with forecasts, prior values and the actual once it prints, plus Fed speakers and auction times. Defaults to yesterday through the next 7 days; widen days_back and days_ahead to see more, or filter to one country like US, EU, GB or JP.

Input parameters:

- `country` (string): Two-letter country or bloc, like US, EU, GB, JP. Empty means everywhere.
- `days_ahead` (integer): How many days ahead to include. Default 7, up to 365.

One economic series in depth

One economic data series: the latest print, the forecast, the surprise in standard deviations, and the history.

Input parameters:

- `slug` (string): Series slug from list_series, like cpi or nonfarm-payrolls.

### `get_auctions` (~277 tokens)

Treasury auction results and tails

US Treasury auction results, measured by Helious at the close: the high yield, the tail against the when-issued yield, bid-to-cover against the tenor's twelve-auction average, who bought (indirect, direct, dealer), and the desk's strong, in line or weak verdict. Pass tenor to ask about one part of the curve, like 10-year-note or 30-year-bond, which is what you want for 'how did the last 10-year auction go'. The tail is the number that answers whether an auction was good or bad, and Helious is the only free source that publishes it.

Input parameters:

- `limit` (integer): Most auctions to return.
- `tenor` (string): One tenor, like 10-year-note, 30-year-bond or 26-week-bill. Plain forms work too: '10y', '30 year'. Or a whole class: bills, notes, bonds, tips, frn. Or a curve SEGMENT, which is usually what 'the fr…

### `get_feed` (~139 tokens)

The Helious feed

The posts Helious publishes: scored releases, auction results, board updates, the daily brief and live squawk lines. Posts carry helious_read, the desk's plain-English line on why it matters. Depth follows your plan (1 day keyless, 7 days free, 12-24 months paid, 10 years Ultimate). Optional q filters by word; categories narrows to chosen lanes. Delayed 60 minutes without a paid key.

Input parameters:

- `categories` (string): Comma-separated lanes, like release,auction. Empty means all.
- `limit` (integer): Most items to return.
- `q` (string): Filter word.

### `get_document_digests` (~150 tokens)

FOMC minutes and speech digests

The desk's read of FULL central bank documents, not headlines: FOMC minutes and Fed/ECB speeches read end to end. Each digest carries a summary, what is genuinely new versus what the market already knew, key findings with their market consequence, a hawkish/dovish committee lean, and quotes verified word for word against the source document. Minutes carry no bond or equity direction on purpose: they describe a meeting about three weeks earlier, so the desk states the lean and declines the market call. Delayed 60 minutes without a paid key.

Input parameters:

- `kind` (string): minutes, speech, or all (default).
- `limit` (integer): Most digests to return.

### `get_fed_roster` (~36 tokens)

The FOMC roster

Who is on the FOMC: governors and presidents, who votes this year, their lean, and their upcoming speeches.

### `get_squawk_sessions` (~50 tokens)

Transcribed live events

Live events Helious transcribed in the last week (Fed pressers, briefings), one entry per event.

Input parameters:

- `hours` (integer): How many hours back, up to 168.

### `get_access_info` (~46 tokens)

Your plan and how to get more

What your current tier can do, the full plan ladder, and the exact steps to tell your user when you need more: make a free account, get a key, or subscribe.

### `get_treasury_curve` (~56 tokens)

The whole Treasury curve

The whole US Treasury curve in one call, 3M bill to 30Y bond with daily closes: live points on Pro and Ultimate, one hour behind on Starter, upgrade steps instead of numbers on the free tiers.

### `get_nasdaq100` (~135 tokens)

NASDAQ-100 board

The NASDAQ-100 ranked best to worst on the session: price, change and sector for every stock. Pass symbol to ask about ONE company instead, like AAPL or NVDA, and you get its price, its move on the session and where it ranks on the board today. Equities are market data: live on Pro and Ultimate, upgrade steps instead of numbers below.

Input parameters:

- `limit` (integer): Most stocks to return.
- `symbol` (string): One or more NASDAQ-100 tickers, comma separated, like AAPL or AAPL,MSFT. Empty returns the whole ranked board.

### `get_rate_odds` (~118 tokens)

Fed rate cut and hike odds

The odds of a Federal Reserve rate cut or hike at each remaining FOMC meeting, priced from fed funds futures. THIS IS THE TOOL for 'what are the odds of a cut in September', 'is the Fed cutting', 'what is priced in for the next meeting' or 'how many cuts this year'. Gives the probability per meeting, the implied effective rate after each one, and the total move priced across the whole path. Computed by Helious from settlement prices against the effective fed funds rate, not the target midpoint.

### `get_market_context` (~137 tokens)

Why the market is moving

START HERE for any 'why is the market doing this' question. One call gives the whole cross-asset board (equities, the Treasury curve, FX, volatility, commodities), every scored economic release behind it, and the Helious desk's read on what is actually driving the session: whether it is event-driven, flow-driven or quiet, the evidence that read rests on, and the regime yields and stocks have actually been trading in. Use this before the individual board tools: it saves five calls, and it characterises the session rather than leaving you to guess a cause. Market data: answers with numbers on Pro and Ultimate.

### `get_earnings` (~125 tokens)

Mega-cap earnings dates and EPS

US mega-cap earnings: when a company reports, whether that date is confirmed or still an estimate, whether it prints before the open or after the close, the consensus EPS, and once it lands the reported EPS with the beat or miss. Pass symbol for one name, like AAPL. This is the tool for any question about a company's earnings date or EPS.

Input parameters:

- `limit` (integer): Most rows to return.
- `symbol` (string): One or more tickers, comma separated, like AAPL or AAPL,MSFT. Empty returns every name tracked.
