Twelve Data
Market prices, indicators and fundamentals from the Twelve Data API
Overview
What Twelve Data does
Twelve Data sells a market data API covering equities, foreign exchange, crypto, ETFs, commodities and bonds across dozens of exchanges. The connector fronts that API so a request phrased in ordinary language is turned into the right endpoint call and parameter set. Behind it sit historical and intraday OHLCV series, a large library of technical indicators, company fundamentals including statements and analyst coverage, and calendars for earnings, IPOs, dividends and splits. An API key is required; Twelve Data offers a free tier and puts real time data, higher rate limits and extended datasets on paid plans. The listing is community tier and publishes documentation.
Tool surface
Twenty seven tools are listed by Twelve Data, and the endpoint answers an unauthenticated tools/list with 401, so how that count divides across price, indicator and fundamentals calls is not visible from outside a keyed account.
Availability
Where Twelve Data is listed
Twelve Data is listed in the Claude connectors directory only. Twelve Data has no app under the same domain in the ChatGPT directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.
The MCP server behind a Claude connector is usually the same server a ChatGPT app would need, so the absence is a distribution decision rather than a technical one.
Claude listing
In the Claude connectors directory
Twelve Data publishes 27 tools to Claude, deeper than 78.2% of the 1,253 Claude-listed connectors.
The median Claude-listed connector filed under Finance publishes 12, so this one runs 15 tools above its bucket's median and ranks 32nd of 159 by tool count.
It falls in the 21-50 tools band, which holds 20% of the Claude directory.
Twelve Data publishes a remote MCP endpoint. Claude connects to it over HTTP; there is nothing to install locally.
Every connector in the Claude directory is remote, all 1,253 of them, so transport is not a differentiator there.

Twelve Data is community-listed in the Claude directory, the tier 770 of 1,253 connectors sit in (61.5%). It is the default for a self-published server, and says nothing either way about quality.
