Lets your AI look up company filings, earnings calls, stock and crypto data, and prediction markets for you.
This is a helper that connects your AI assistant to Octagon, a service that gathers financial and market information. Once it is set up, you can ask your AI questions about companies, stocks, crypto, and prediction markets, and it will go fetch the answers for you. It is handy for anyone who does research on companies or markets but does not want to dig through filings and news by hand.
What is an MCP server? The 30-second version
On its own, your AI can only chat with you using what it already learned. An MCP server is a small helper program that gives your AI a new skill or a connection to another service. This one connects your AI to Octagon, a market intelligence service. So when you ask about a company or a market, your AI can reach out through this helper and bring back real information instead of guessing.
What this MCP server does
You ask your AI a question in normal words, like how a company's revenue changed or what its latest earnings call said. Your AI passes that question to this helper, which sends it to Octagon's agents. Octagon looks through filings, earnings transcripts, market data, news, and prediction market reports. Then the answer comes back and your AI explains it to you in the chat, often with numbers and details you can use.

What it gives back to you
You get answers in plain text right in your chat, usually with the numbers, dates, and details you asked about. Some questions come back as lists or short summaries, like a set of financial ratios or recent headlines. If the AI needs one more detail from you, it will ask a short follow-up question. For prediction markets, you can also get structured historical data.
