Twelve Data + ChatGPT
Market data for AI agents from Twelve Data: real-time quotes and prices, historical time series, exchange rates and currency conversion, symbol search, stock, forex and crypto lists, exchanges and market hours, and RSI, MACD, SMA, EMA and Bollinger Bands. 19 read-only tools, API key.
Prerequisites
See the full setup instructions baked into the connector (visible in the in-app store when you select the connector). The required environment variables for this connector are:
TWELVE_DATA_API_KEY
Step 1 — Get credentials
- Create a free account at https://twelvedata.com and open API Keys in the dashboard.
- Copy the key into
TWELVE_DATA_API_KEY. It is sent in theAuthorization: apikeyheader, so it never appears in a URL or a log. - Resolve a name into a symbol with
twelve_data_search_symbols(for example Siemens to SIE on XETR), then calltwelve_data_get_price,twelve_data_get_quoteortwelve_data_get_time_series. For currencies usetwelve_data_get_exchange_rateortwelve_data_convert_currencywith a pair such as EUR/USD.
The free Basic plan allows 8 API credits per minute and 800 per day; most tools cost 1 credit per symbol. Above that the API answers 429 until the next minute. Free plans cover US equities, forex and crypto; many non-US exchanges and fundamentals need a paid plan and answer 403. twelve_data_get_api_usage shows your usage against the plan limits. Prices come back as strings, newest first unless order is asc.
Step 2 — Install the adapter
curl -fsSL https://raw.githubusercontent.com/HelpCode-ai/anythingmcp/main/docker-compose.quickstart.yml -o docker-compose.yml
printf 'JWT_SECRET=%s\nENCRYPTION_KEY=%s\n' "$(openssl rand -hex 32)" "$(openssl rand -hex 32)" > .env
docker compose up -d
Step 3 — Add the connector in ChatGPT
Your server URL: in AnythingMCP, open MCP Servers → the server this connector is on, and copy its URL (
https://cloud.anythingmcp.com/mcp/…). Use it wherever this guide showsYOUR_SERVER_ID.
ChatGPT connects to MCP servers as custom apps in developer mode, available on paid plans (not on Free). On Business and Enterprise workspaces an admin may have to allow it first.
- In ChatGPT, open Settings → Security and login and turn on Developer mode.
- Go to chatgpt.com/plugins and click +.
- Enter a name and a short description, e.g. Name:
Twelve Data. - Under Connection, enter the MCP server URL
https://cloud.anythingmcp.com/mcp/YOUR_SERVER_IDand create the connection. - When ChatGPT asks, sign in to AnythingMCP (OAuth) and allow access.
