Claude Twelve Data connectorWhat Claude can do in your Twelve Data account.
The Claude Twelve Data connector exposes 27 tools: 25 read, 2 write, 0 undocumented. The 25 read tools pull prices, indicators, fundamentals, funds, filings and market news; the 2 others handle sign-in in Twelve Data's open-source server and touch no market data.

What changes when Claude can query Twelve Data
With this connector, you ask Claude a market question in plain words, say the RSI of a stock or its latest earnings, and it calls Twelve Data's tools while it answers: prices, technical indicators, fundamentals, funds, filings and news, through your Twelve Data account.
A quick read of a ticker. get_quote returns a real-time snapshot with open, high, low, close and volume, and get_technical_indicator computes indicators such as RSI, MACD or ATR on the same symbol.
Fundamentals without a filing cabinet. get_financials brings income statement, balance sheet or cash flow, annual or quarterly, while get_statistics adds valuation ratios, margins and dividend yield.
The market calendar. get_earnings, get_dividends, get_splits and get_ipo_calendar show what is coming up, and get_regulatory_data lists insider trades or SEC filings.
What it will not do: no tool places an order, manages a portfolio or trades on your behalf. Market indices, options and bonds are not supported by the price tools; Twelve Data points to ETF proxies instead. And nothing runs on its own: Claude calls these tools while it answers you, it does not watch prices. A scheduled alert belongs to an automation platform; our Integrations hub lists the ones we cover.
Five words before you connect
Claude's vocabulary around this connector, in one minute.
- Connector
- The link you set up once between Claude and an account you already have, so Claude can use it while it answers you.
- Tool
- One named capability a connector gives Claude. Claude decides which to call; the directory sheet lists all 27 of them by name.
- Authorization
- The service's sign-in screen, where you grant the access Claude uses. For Twelve Data, a browser login to your account. Revocable.
- Approval
- The confirmation Claude waits for before it changes something in an account for you, shown in the chat at that moment.
- MCP
- The shared standard behind connectors: it is what lets an assistant like Claude request data from a service such as Twelve Data.
Connect Twelve Data to Claude in three steps
- 01
Find Twelve Data in the connector list
Open Claude's settings, go to Customize, then Connectors, and look for Twelve Data. On a Team or Enterprise workspace, an Owner or Primary Owner has to enable it for the organization before members connect.
- 02
Log in to your Twelve Data account
Click Connect. Twelve Data says a browser window opens for you to log in, and your personal API key is then linked automatically, with nothing to copy. If the link breaks, Disconnect and connect again.
- 03
Read the authorization screen
Look at what the Twelve Data screen asks before you authorize. It is the service's screen, not Claude's, and it decides what the access covers. You can withdraw it later the same way.
The 27 tools, sorted by what they do
Twelve Data gives Claude 27 tools: 25 that read your account, 2 that change something in it.
Twenty-five tools read market data and two belong to a sign-in flow. The descriptions used here come from the code of Twelve Data's open-source server, where all 27 names on the directory sheet exist; the hosted connector's own tool list requires a login and is not public. The names stay exactly as Claude shows them.

What Claude reads (25)
25 toolsTwenty-five tools that fetch prices, fundamentals, funds, calendars and reference data.
auth_status
Reports the current authentication state for debugging: which credentials are configured and whether sign-in tokens exist.
currency_conversion
Gives an exchange rate, or converts an amount, between two currencies, fiat or crypto. Without a date it uses the real-time rate; with a date it returns the historical rate for that day.
get_analyst_data
Pulls analyst ratings, consensus price targets and forward estimates for a stock or an ETF, in one answer rather than across several sources.
get_api_usage
Shows how many Twelve Data API credits you have consumed and the limits of your plan. Twelve Data's code also presents it as a way to check that authentication works.
get_company_info
Describes a listed company three ways: its profile (description, sector, industry, employees, CEO, website), its key executives with name, title and compensation, or its logo.
get_company_news
Fetches the latest news, press releases and announcements of a company, from 1 to 10 releases per request, with 5 as the default when you do not say how many.
get_dividends
Lists a stock's dividend history or, with the calendar option, the upcoming ex-dividend dates across the market, depending on what you ask.
get_earliest_timestamp
Tells how far back the history of an instrument goes at a given interval, by returning the earliest available date and time.
get_earnings
Returns a company's earnings per share history, actual against estimate with the surprise percentage, or the market-wide calendar of earnings, depending on what you ask.
get_etf_data
Provides ETF analytics, from a summary with assets under management, expense ratio, net asset value and category, to the top holdings and the sector and asset-class weights.
get_financials
Brings a company's financial statements: income statement, balance sheet or cash flow, annual or quarterly, with assets, liabilities, equity, cash and debt on the balance sheet side.
get_ipo_calendar
Shows upcoming and recent initial public offerings, each with its price range, offer price, currency and share count, so new listings come to the conversation.
get_market_cap
Gives a company's current market capitalization, or a historical series of values when Claude passes a start date and an end date.
get_market_movers
Ranks the biggest gainers, losers or most active instruments in the market you pick: stocks, ETFs, mutual funds, forex, crypto or commodities.
get_market_state
Tells whether exchanges are trading right now and gives their trading hours; with every filter left blank, it covers all major markets at once.
get_mutual_fund_data
Covers mutual funds from several angles: summary, performance, risk, ratings, holdings, and a sustainability view with ESG scores and controversy metrics.
get_price
Returns the current real-time price of one or several symbols in a single call.
get_quote
Delivers a fuller real-time snapshot than the price alone: open, high, low, close, volume, percentage variation and 52-week range, for a stock, ETF, forex pair or crypto.
get_reference_data
Serves reference and dictionary data, such as exchanges, countries and instrument types, as well as the trading hours and holiday schedule of an exchange.
get_regulatory_data
Retrieves regulatory and ownership data, such as recent insider buying and selling by officers and directors, or recent SEC filings like 10-K, 10-Q and 8-K reports.
get_splits
Lists a company's past stock splits with their ratio and date or, at market level, the calendar of upcoming splits.
get_statistics
Gathers key fundamental statistics for a stock or ETF: revenue, margins, return on assets and on equity, earnings per share, beta, 52-week range, short ratio and dividend yield.
get_technical_indicator
Computes a technical indicator for a symbol, among the many Twelve Data supports, with volatility measures such as ATR, NATR or SuperTrend among them.
get_time_series
Returns historical open, high, low, close and volume data for an instrument, 30 data points by default and up to 5000 per request.
search_symbol
Finds financial instruments by name or partial ticker, or finds the cross-listings of a symbol.
Sign-in tools marked as writing (2)
2 toolsTwo tools from the open-source server's login flow. They store credentials, not market data. No source describes a confirmation for them, so the general rule below applies.
oauth_configure
Approval: see the ruleIn Twelve Data's open-source server, saves OAuth credentials to a local configuration file, to be run once before the login tool.
oauth_login
Approval: see the ruleStarts a login through OAuth, in Twelve Data's open-source server: a browser window opens for you to authorize access, then the API token is fetched from your profile and saved locally.
What Claude asks before acting
Claude's default is to stop and ask before any action it takes on an account for you. Here, 25 tools only read market data, and the 2 others belong to sign-in: no source describes a confirmation specific to them.
On Team and Enterprise workspaces, owners decide whether members may let some actions through without a new prompt, and they can restrict what a connector does for the whole organization, keeping reads open and blocking writes, for instance. No member overrides that from a personal account. Claude works with the rights of the person who connected it, never more. The official per-tool read or write label only appears in a connected account's settings.
Which Claude plans include it
None of the 819 sheets in the official directory shows availability by plan. Connector by connector, that answer is not published anywhere.
The published rule is general: remote connectors are open to all users on Claude, Cowork, Claude Desktop and mobile, and on Team and Enterprise an Owner or Primary Owner enables a connector before members connect. Twelve Data's own subscription is a separate question and decides how much data you can pull. For this connector's state, open its directory sheet.
Where the Claude Twelve Data connector stops
A connector is not an automation. Claude queries Twelve Data while it answers you; nothing fires when a price crosses a threshold.
A tool list made mostly of reads is an observed floor, not a guarantee: an admin can open actions that no public sheet shows. The verification badge is not a security audit, and Anthropic says on every sheet that it does not decide a publisher's tools. Only Twelve Data documents this connector, in its docs, its directory description and its open-source code; no Claude help article or Anthropic developer page covers it.
