Overview

AI-generated overview

Read-only remote MCP server giving an assistant live US stock, ETF and crypto prices, technical indicators, key levels, market breadth, sentiment and news.

What you can do
  • Fetch quotes, session state, 52-week ranges, earnings dates and daily OHLCV price history
  • Compute technical indicators, support/resistance levels, relative strength between two tickers and historical base rates for active events
  • Read market-wide context: S&P 500 breadth, VIX and put/call ratios, intermarket ratios, Treasury yields, CPI and sector data
  • Read crypto context: BTC/ETH dominance, funding rates, open interest, stablecoin ratio and Fear & Greed
  • Retrieve recent news for a ticker or search news by topic, with source links
  • Look up the provider's technical-analysis methodology notes and monitoring setup options
When to use it
Useful when you want an assistant to answer questions about US-listed stocks, ETFs, bitcoin, ether or the VIX with current data and technical analysis, without setting up an account or API key.
Requirements
A remote MCP endpoint over Streamable HTTP; no account, API key or environment variables are needed. Network access to the provider is required, and fair-use rate limits apply per client.
Before you install
Read-only: it cannot place trades, move money or read uploaded files. Prices are delayed up to 15 minutes, and forex, futures, options chains and most non-US listings are not covered. Answers may include links to the provider's site, and news items point to third-party articles. It is research and education, not investment advice.

Installation

In SourceWeft

  1. Open MarketCrew — live market data & stock analysis 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/ai.marketcrew%2Fmarket-data/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

Other MCP clients

Add this to your client's mcpServers config.

Plugin skills

Installed as a Claude plugin, this repository adds four skills on top of the connector:

  • stock-check: price, trend, RSI and MACD, support and resistance, next earnings date and news for one ticker
  • market-check: risk-on or risk-off posture, market breadth, put/call ratios, the VIX and the macro backdrop
  • crypto-check: bitcoin and ether price and levels, dominance, funding, open interest and ETF flows
  • compare-assets: which of two assets is leading, through their price ratio

Limits

Fair-use rate limits apply per client. Prices are delayed up to 15 minutes. Forex, futures, options chains and most non-US listings are not covered.

get_price_history

Price history (OHLCV)

Get daily OHLCV price history for a ticker: open/high/low/close/volume. Use period_days to control how far back (default 365, max 3650).

Parametersbarstickerrequiredto_datefrom_dateperiod_days

get_technical_indicators

Technical indicators

Calculate technical indicators for a ticker: SMA(50/200), RSI(14), MACD, ATR(14), ADX(14) trend strength, Stochastic(14,3), volume (OBV trend + volume vs 20-day average), RSI/price divergence, Golden/Death Cross, and RSI regime. Computed from daily price history.

Parameterstickerrequired

get_relative_strength

Relative strength (A/B)

Relative strength of one ticker against another as a price ratio A/B (e.g. GDX/GLD, HYG/LQD, XLK/SPY, NVDA/SPY): how far the ratio sits above or below its 50- and 200-day averages, the ratio's RSI and trend, recent values, and a one-line verdict on which side is leading.

Parametersticker_arequiredticker_brequiredperiod_days

get_key_levels

Key price levels

Compute key price levels for a ticker: support/resistance zones (clustered swing highs/lows with touch counts = how often price reacted there), nearby round numbers, 50/200-day moving averages, and the 52-week high/low. Returns nearest levels above (resistance) and below (support) with distance %. Use these for concrete trigger/target/invalidation levels.

Parameterstickerrequired

get_intermarket

Intermarket compass

Intermarket compass — a first-pass read of the market environment through price-ratio lenses: asset-class rotation (bonds vs stocks, commodities), risk appetite (high-yield vs investment-grade credit, small vs large caps, cyclicals vs defensives), defensive flows (gold, utilities, yield-curve proxy) and the dollar. Each lens reports rising/falling vs its 50-day average plus the 20-day change; overall posture is risk_on, risk_off or mixed. Optional focus= ('gold'|'bonds'|'tech'|'commodities'|'equity'|'crypto') adds lenses specific to that asset class.

Parametersfocus

get_market_breadth

Market breadth (S&P 500)

S&P 500 market breadth: the percentage of index members above their 50-day and 200-day moving averages, with RSI, trend and 52-week range for each breadth series. A gauge of how broad the current advance or decline is.

Takes no parameters.

get_sentiment_data

Market sentiment

Market sentiment: the VIX level with its 1-day, 5-day and 1-month change and 52-week range, and Cboe's daily put/call ratios for all products, equities, indices, SPX and VIX options with the underlying call and put volumes. Flags a contrarian extreme when the equity put/call ratio or the VIX sits at one.

Parameterstype

get_macro_context

Macro context

Get macro market context: sector P/E ratios, sector performance, US Treasury rates (2Y/10Y/30Y), CPI inflation data. Also provides key inter-market ratios (HYG/LQD, TLT/SPY) from our price data.

Takes no parameters.

get_crypto_context

Crypto market context

Crypto market context for a technical read: BTC/ETH dominance and total/alt market cap, Fear & Greed sentiment, perp funding rate & open interest (positioning/leverage), and the Stablecoin Supply Ratio (dry powder). Use ONLY when analysing crypto assets (BTC, ETH, crypto ETFs). Background context, not the primary signal.

Takes no parameters.

get_instrument_info

Instrument info

Current snapshot of one instrument: price and recent changes, session state (regular, pre-market, after-hours, closed), 52-week range, and market cap, sector and next earnings date where they apply. Covers the S&P 500, the Nasdaq-100 and popular US ETFs, major cryptocurrencies and the Cboe Volatility Index; crypto uses the -USD pair form (BTC-USD, ETH-USD), the VIX is ^VIX. Forex pairs, futures, options, other indices and non-US listings are not covered. Pass a ticker such as 'AAPL', 'SPY', 'BTC-USD' or '^VIX'.

Parameterstickerinstrument_id

get_event_stats

Event base rates

Historical base rates for the technical events firing on a ticker today (e.g. RSI below 30, golden/death cross, new 52-week high/low). For each active event: the forward returns (1w/1m/3m/6m/1y) seen historically after similar events across the US universe, with the sample size and an unconditional baseline to compare against. Answers 'what usually happened after this'; small samples warrant caution.

Parameterstickerrequired

public_instrument_news

Instrument news

Latest news for a ticker — headline, a short summary and a mandatory source_url to the original article (never the full third-party text). Use to ground a market read in recent, attributable news.

Parameterslimittickerrequireddays_back

public_search_news

News search

Semantic news search across tracked instruments — returns matching items with a short summary and a mandatory source_url (never full article text).

Parameterslimitqueryrequireddays_backmin_similarity

get_ta_methodology

Parametersqueryrequiredtop_k

get_monitoring_options

Monitoring options

Returns available options for ongoing monitoring — price alerts, idea tracking, watchlist monitoring, scheduled digests — with setup instructions and channels (email/Telegram). Call only when the user asks for ongoing monitoring or notifications; never needed to answer a question.
