Show HN: Wealthnow – a read-only financial data MCP server with OAuth sign-in (wealthnow.io)

Wealthnow has launched a read-only financial data MCP (Model Context Protocol) server that allows AI agents—including Claude, ChatGPT, Cursor, and Codex—to access a wide array of financial information via OAuth sign-in. This server facilitates seamless interactions with the Wealthnow financial data API, which includes market data, SEC filings, congressional trades, and more, using Streamable HTTP. With a straightforward connection process, users can authenticate their AI agents to fetch real-time financial insights without the need for API keys, thereby enhancing the usability of AI tools in financial analysis. This launch holds significant implications for the AI/ML community as it democratizes access to robust financial data, allowing developers to build more informed and capable applications that can aid in tasks like investment analysis or market research. The read-only nature of the server ensures that it cannot execute changes or trades, maintaining user account security and compliance. Furthermore, the pricing structure offers flexibility, with tiers ranging from a free plan to a specialized enterprise solution, making it accessible for various use cases and allowing developers to leverage advanced data insights effectively.
