Overview

AI-generated overview

Remote MCP server giving an assistant live US rates, macro and cross-asset market intelligence from the Helious desk, including curve regime, auctions, releases

What you can do
Read the US Treasury curve, yields, spreads and curve regime, plus history of regime flips and official yield closes. Track rate expectations: market-implied rate paths, Fed cut/hike odds per FOMC meeting, and Treasury issuance and auction results. Pull US macro data: inflation and employment measures, individual economic series, and the economic calendar. Monitor cross-asset boards: FX momentum, implied volatility, cross-asset correlations, NASDAQ-100 rankings and mega-cap earnings. Follow the desk's output: scored feed posts, central bank document digests, FOMC roster, transcribed squawk sessions and Hormuz transit counts. Check plan limits and credit wallet, and get a one-call market-con
When to use it
Use it when questions turn on US rates, Fed policy expectations, Treasury auctions, macro releases or cross-asset context, and you want desk-style interpretation rather than raw data. Useful for a quick read on why a session moved, or for scheduled macro and earnings awareness.
Requirements
Remote streamable HTTP endpoint at helious.io; no local runtime, packages, environment variables or headers declared. Access is tiered: some tools work keyless or free, while live market data and deeper history require a paid plan and credits.
Before you install
Several tools return numbers only on paid tiers and otherwise return upgrade steps, and calls can spend credits from a wallet. Data depth is limited by plan (feed history from 1 day keyless to 10 years). Market data may be delayed by an hour on lower tiers. No authentication is declared in the manifest, so confirm how your key is supplied before relying on paid access.

Installation

In SourceWeft

  1. Open Helious market intelligence in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.helious%2Fmarket-intelligence/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Tools

get_rates_and_curve

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.

Parametersfresh

get_curve_history

Curve regime flips

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

Parametersfreshlimitsince

get_fx_board

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.

Parametersfreshlimitsince

get_vol_board

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.

Parametersfreshlimitsince

get_inflation

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.

Parametersfreshwindowhistorymeasures

get_jobs

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.

Parametersfreshwindowhistorymeasures

get_rate_path

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.

Parameterslanefreshhistory

get_treasury_issuance

Treasury borrowing and cash

Monthly US Treasury borrowing: marketable debt sold, gross and net, split into bills, notes (TIPS and floating-rate notes included) and bonds, the cash balance the Treasury holds at the Fed, a quarterly rollup, and the refunding schedule ahead. Figures are billions of dollars. `measures` filters by key, `history` adds the monthly series. Published statistics, so it answers on every tier; the history depth follows your plan.

Parametersfreshhistorymeasures

list_series

Economic series Helious tracks

Every US economic data series Helious tracks (CPI, payrolls, GDP and so on) with its slug for get_series. Free: it spends no credit.

Takes no parameters.

get_series

One economic series in depth

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

Parametersslugfresh

get_auctions

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.

Parametersfreshlimittenor

get_feed

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.

Parametersqfreshlimitcategories

get_document_digests

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.

Parameterskindfreshlimit

get_fed_roster

The FOMC roster

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

Parametersfresh

get_squawk_sessions

Transcribed live events

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

Parametersfreshhours

get_access_info

Your plan and how to get more

What your current tier can do, the full plan ladder, your credit wallet (what a call costs, what is left), and the exact steps to tell your user when you need more: make a free account, get a key, buy credits, or subscribe. Free: it spends no credit.

Takes no parameters.

get_treasury_curve

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.

Parametersfresh

get_nasdaq100

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.

Parametersfreshlimitsymbol

get_rate_odds

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.

Parametersfresh

get_market_context

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.

Parametersfresh

get_earnings

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.
