AI agents are only as useful as the data they can reach. Quantustik runs a hosted Model Context Protocol (MCP) server that gives an agent structured, read-only access to S&P 500 market data, so it can answer questions from live figures instead of guessing or scraping a web page.
The server runs at quantustik.com/mcp (streamable-HTTP, no API key required to start) and is described by a public manifest at /.well-known/mcp.json. The tools cover market conditions, the Fear & Greed index, market indicators, per-ticker indicators, the earnings calendar, insider and institutional activity, and SEC filing digests. The exact, always-current list comes from the server itself rather than a number restated here.
MCP is a data-access convenience, not a trading connection. No tool places or manages an order, and every response carries the date it was generated, so an agent can say how fresh a figure is.
MCP is a data-access layer, not a trading connection: it only reads market data, it never places or manages an order, and no autonomous trading is wired to it. Every tool is callable without an API key (anonymous access is rate-capped per hour; an optional free key raises limits). The protocol changes how an agent reaches the data, not how reliable the underlying data sources are.
