MCP connection guide

Connect once.
Ask a research question.

Three read-only tools. No account, key, or local installation needed with a compatible remote MCP client.

Add the hosted server.

Choose a remote Streamable HTTP connection in your client, enter this URL, and select no authentication:

https://chartlibrary.io/mcp

Setup screens and connector availability depend on the client. Chart Library research is free; any client or model-provider charges are separate.

Try one call.

“Use Chart Library to read AAPL’s latest completed-session market state. Keep the session date, sample sizes, historical outcome ranges, informative receipts, and warnings.”

Your client should discover market_state, daily_note, and research_quality. The question above needs only market_state. An optional date selects a historical session; latest is not a real-time quote.

Need a command-based client?

The MCP source and release notes cover the Python client. Check the release’s supported tools and dependencies; package releases and the hosted service can differ. The hosted URL above is the primary getting-started path.

Keep the evidence intact.

The default tools are read-only. Retrieving research does not require permission to send messages, place orders, or change accounts. Missing or weak evidence should remain visibly missing or weak.

Historical excess-return ranges are not automatically calibrated forecasts. The calibration receipt applies only to the method and population it names; daily notes have a separate settled-note tally.
