How to Use the Twelve Data MCP in Claude Code

Q: How do I get historical candles using Twelve Data with Claude Code?

You run gettimeseries in your terminal script. You pass the symbol and the time interval as parameters, and the output streams directly to stdio for piping into other tools.

Q: Can Twelve Data provide crypto prices for my scripts using Claude Code?

Yes. Use getcryptolist first to validate available exchanges, then run a script that pulls the current pricing data via the MCP Server endpoint. It’s ideal for automated nightly reports.

Perplexity

Scheduled Indicator Checks in Pipelines

Set up a cron job or GitHub Action to run scheduled checks. You can call `get_rsi` on critical symbols, making your CI/CD pipeline fail if the value moves outside acceptable ranges (e.g., above 70). The output is direct, machine-readable data. This works headless. Your script just needs to pipe the result of the indicator check into a log file or another analysis tool.

Batch Time Series Data Export

Need historical data for quarterly reporting? Use `get_time_series` to fetch OHLCV candle data for multiple assets across various intervals. The output is structured, making it perfect for piping directly into a database ingest script. This capability means you don't need manual intervention; the script grabs the data and pipes it out, ready for the next stage of your pipeline.

Market Symbol Verification Before Deployment

Before starting a build that requires market data, run `search_symbols` to ensure all necessary instruments exist. This prevents runtime errors in production scripts. You can write logic that checks for available exchange rates (`get_exchange_rate`) first, failing fast if the required currency pair isn't active.
