Perplexity

Cascade chains Marketaux MCP Server data

You drop a single prompt into Windsurf asking for a market breakdown. Cascade takes over, hitting `get_stock_market_status` to check if exchanges are open before doing anything else. It doesn't wait for your permission to pull the data. Once it knows the market status, the agent runs `get_trending_news` to find what traders care about right now. It reads the context, figures out which tickers matter, and hands you a finished briefing document.

Autonomous sentiment tracking

Building trading algorithms means constantly checking how the market feels about specific assets. You tell Cascade to build a sentiment monitor, and it wires up `get_sentiment_analysis` directly into your Python script. The agent knows how to map those sentiment scores to actual companies using `get_entities` and `get_symbols`. It writes the fetch logic, parses the JSON response, and structures the output while you watch.

Global exchange mapping

Finding the right market indices used to mean digging through API docs for hours. Cascade handles that by calling `search_exchanges` and `list_industries` to map out the exact sectors you want to target. When you need historical context, it pulls `get_latest_news` and `search_news` to cross-reference past events with current market conditions. The IDE builds the entire data pipeline autonomously.

Common questions about Marketaux MCP in Windsurf

Edit `~/.codeium/windsurf/mcp_config.json` and add the server details under the `mcpServers` object. You can also use the Settings -> Cascade -> MCP Servers UI. Hit refresh in the MCP panel and Cascade will auto-discover the endpoints.

Yes. Cascade reads your goal and sequences the tools on its own. It might run `search_news` first, parse the results, and immediately pass the relevant tickers into `get_sentiment_analysis`.

No. Once you configure the MCP server, Cascade executes the calls autonomously. You just set the objective, and the agent pulls the financial intelligence without pausing for approval.

Because your code lives in the IDE. Cascade directly injects `get_indices` and `get_symbols` data into your trading logic. You skip the copy-pasting and let the agent write the integration.

Vinkius runs this MCP server in an ephemeral V8 isolate sandbox. When Cascade requests global financial news or entity mappings, the system routes the request via a zero-trust endpoint token. The sandbox spins down immediately after the API returns the sentiment scores, leaving no residual traces.
