Alpha Vantage MCP Server Tools & Capabilities (126)
Tool names from Anthropic's directory listing. This server requires sign-in, so we could not read tool descriptions or parameter schemas.
Limits
- The free quota is 25 requests per day, and tool calls spend it fast. Alpha Vantage's own worked examples use two and three calls per question. Budget accordingly, or expect quota errors mid-conversation.
- Six endpoints are badged premium in Alpha Vantage's API documentation: Realtime Bulk Quotes, Index Data, FX Intraday, Crypto Intraday, VWAP and MACD.
MACDsitting behind the paywall matters more than the others, since it is one of the most-requested indicators on the server. - Realtime and 15-minute-delayed US market data is premium-only by regulation. Alpha Vantage attributes this to exchange, FINRA and SEC rules rather than to its own pricing choice. On a free key, expect historical data.
- We could not read tool schemas or safety annotations. The endpoint requires authentication, so the 126 count and the tool names are the directory's, and parameter-level detail is not published here. What we did read is the auth posture and the scopes.
- The vendor's Tools Reference and the directory listing disagree by eleven names in one direction and three in the other, as of the dates above.
- Two of the 126 tools return no market data.
PINGandADD_TWO_NUMBERSare documented diagnostics. - The connector delivers data, not analysis. Alpha Vantage's suggested agent instructions tell the assistant to source market queries from the server rather than from prior knowledge, which is a hedge against a model narrating numbers it did not fetch.
Frequently asked questions
Can the Alpha Vantage MCP server change anything in your account?
No write scope is advertised. The server's own OAuth descriptors name exactly one scope, alphavantage:read, and we read both of them directly from the endpoint on 2026-08-18. Every tool in the listing fetches market data. That is the scope the server publishes, not a per-tool guarantee, but it is strong evidence the connector only reads.
Are there usage limits on the free Alpha Vantage API key?
Yes, and they are strict. Alpha Vantage's support page states the free tier covers 25 API requests per day across the majority of its datasets, with unlimited requests for verified open-source or educational projects. Every MCP tool call spends one request, so a single charting conversation can exhaust a day's free quota.
How much does an Alpha Vantage premium key cost?
Premium plans start at 49.99 dollars a month for 75 requests per minute, rising through 150, 300, 600 and 1200 requests per minute at 99.99, 149.99, 199.99 and 249.99 dollars respectively, per Alpha Vantage's premium page in 2026. Commercial-licence pricing for the same rate tiers runs from 499 to 2499 dollars a month.
Which Alpha Vantage tools require a paid key?
Alpha Vantage's API documentation badges six endpoints as premium: Realtime Bulk Quotes, Index Data, FX Intraday, Crypto Intraday, VWAP and MACD. It separately notes that realtime and 15-minute-delayed US market data is premium-only, because exchange, FINRA and SEC rules govern its distribution. Historical data on those endpoints remains available on a free key.
How do you sign in to the Alpha Vantage MCP server?
You paste an Alpha Vantage API key into an authorisation page, not a username and password. Alpha Vantage documents that connecting opens a consent page where you enter and authorise your key, and that rotating it means disconnecting and reconnecting. A deprecated legacy option puts the key in the URL query string instead.
Why does the Alpha Vantage connector expose a tool called ADD_TWO_NUMBERS?
It is a deliberate example tool, not an accident. Alpha Vantage's own Tools Reference lists a ping category holding exactly two entries, describing PING as a health check that returns pong and ADD_TWO_NUMBERS as an example tool for adding two numbers. Both ship in the published 126-tool listing alongside the 124 market-data tools.
