Use Alpha Vantage data with AI, safely

Sets up how the assistant reads Alpha Vantage market and fundamental data: it confirms the symbol, date window and asset type first, keeps responses small, and reports rate-limit or key problems instead of guessing. The connector is read-only, so it never changes your account.

Use it when

You want stock or commodity data from Alpha Vantage and need the right symbol and window first
A rate limit or key error stopped a previous analysis and you want to know what to do next
You are not sure which Alpha Vantage tool fits your question

Tools it uses

CASH_FLOW
COMPANY_OVERVIEW
BRENT
COFFEE
COPPER
CORN
ALUMINUM

ADD_TWO_NUMBERS

Example

Pull two years of weekly closing prices for Brent and tell me the high, the low and the overall change.

Scope: Brent crude, weekly bars, two years. The series opened near the start of the window and closed higher overall, with a high and low I have read from the returned data. I summarised the key points rather than listing every row, and noted that the source reports Brent in dollars per barrel. Nothing was written to your account.

Commodity price trend check

Checks whether Brent, coffee, copper, corn or aluminum is rising, falling or flat over a chosen window, and how it compares with the others. It states the window and separates a real trend from normal month-to-month noise.

Use it when

You want to know if oil has been going up or down over the past year
You are comparing how coffee and corn have moved recently
You need to tell whether a commodity is trending or just moving sideways

Tools it uses

ALL_COMMODITIES

Example

Has copper been rising or falling over the last 12 months, and how does it compare with aluminum?

Over the 12 months to the latest month, copper is up 9.6% while aluminum is up 2.1%, so copper leads by about 7.5 percentage points. Copper's monthly moves are typically around 3%, and its 9.6% gain clears that bar, so it reads as rising. Aluminum sits within its normal range and reads as flat.

Review a company's fundamentals with AI

Pulls a listed company's overview, balance sheet and cash flow statement, checks them against each other, and flags debt build-up, shrinking margins or earnings that cash does not support. It reads the figures only and never changes anything.

Use it when

You are weighing a stock and want to know if its reported numbers are getting healthier or weaker.
You suspect profits are not turning into cash and want the periods that show it.
You want a short, sourced read of a company's debt and cash trends before a deeper dive.

Tools it uses

COMPANY_OVERVIEW
BALANCE_SHEET
CASH_FLOW

Example

Review the fundamentals of Microsoft (MSFT) over the last five years. Are profits backed by cash, and is debt rising?

Revenue and operating cash flow both rose across the five annual periods, so the earnings look backed by cash. Total debt was broadly flat while free cash flow grew, which is reassuring. One watch item: receivables grew faster than revenue in two of the periods, so I would check collection timing before drawing a firm conclusion.

Sliding-window stability report for a price series

Measures rolling volatility, return stability and regime shifts over time using sliding and fixed window analytics, then writes a short report on whether a stock's behaviour is stable or changing. The connector is read-only, so nothing is changed.

Use it when

You want to know whether a stock's volatility has changed over the past year
You need to check if a return pattern is stable or shifted to a new regime
You want windowed statistics compared across quarters without overlapping-window errors

Tools it uses

ANALYTICS_SLIDING_WINDOW
ANALYTICS_FIXED_WINDOW

Example

Has AAPL's daily return volatility changed over the last two years? Use 60-day windows and tell me whether the behaviour is stable or shifted.

Over the last two years, AAPL's 60-day rolling volatility sat in a range of about 14 to 22 percent annualised. From March to August 2025 it moved up and stayed elevated for roughly five consecutive windows, so I read that as a regime shift, not a single spike. Removing the largest one-day gap leaves the shift intact, so confidence is medium because the history covers only two years.

Screen a stock's technical indicators with AI

Reads a symbol's trend, momentum, volatility and volume indicators together and returns a one-page read that calls out where the signals agree and where they conflict. It only reads data and never places trades.

Use it when

You want a quick technical read on a stock before deciding whether to look closer.
You need to know whether a trend is strengthening or fading.
You want to check whether a breakout has volume behind it.

Tools it uses

ADX
ADXR
AROON
AROONOSC
CCI
CMO
BOP
ATR
BBANDS
AD
ADOSC
APO

Example

Give me a technical read on AAPL over daily bars, focusing on trend and momentum.

AAPL on daily bars, using ADX(14), CCI(20) and ATR(14). Trend strength is 27 and rising, and price is making higher highs. Momentum confirms with a higher CCI high, so there is no divergence. ATR suggests a normal daily move of about 2.1%. Overall read: bullish lean, with volume confirming the move. Lagging indicators, so this describes past price action, not the business.

How Alpha Vantage skills work

Connect Alpha Vantage
The Alpha Vantage MCP server gives the agent its tools.
Ask in plain words
“Has copper been rising or falling over the last 12 months, and how does it compare with aluminum?” Each SKILL.md says when it applies, so only the one that fits is loaded.
Approve any change
The agent calls the tools in order, checks its work, and shows you any change before it makes it.

Alpha Vantage skills FAQ

What is a Alpha Vantage agent skill?

A SKILL.md file: a short playbook an AI agent loads when your request matches it. Each Alpha Vantage skill describes one job, which Alpha Vantage tools to use in which order, what to check first and when to stop and ask you.

Do the Alpha Vantage skills change anything on their own?

4 of the 5 only read. The others tell the agent to show you the change and wait for a yes before it creates, edits or deletes anything in Alpha Vantage.

Which tools can use these skills?

Any agent that reads the open Agent Skills format: Claude Code, Cursor, Codex, VS Code with Copilot and RevampKey. In RevampKey they are attached when you connect Alpha Vantage; elsewhere you copy the folders into your project or skills directory.

Do I need the Alpha Vantage MCP server too?

Yes. The skills tell the agent how to do the work; the Alpha Vantage MCP server gives it the tools to do it. The Alpha Vantage MCP setup guide covers every client.
