Deliver real-time investment research with extensive private and public market data.
Octagon becomes available to MCP clients through the octagon mcp server. Deliver real-time investment research with extensive private and public market data.
The Octagon MCP server provides specialized AI-powered financial research and analysis by integrating with the Octagon Market Intelligence API, enabling users to analyze and extract insights from public filings, earnings calls, financial metrics, stocks & crypto data, stock news, and prediction markets news & research within Claude Desktop and other popular MCP clients.
Once connected, the assistant can call these 5 tools directly:
Multi — source synthesis for investment research questionsoctagon-prediction-markets — agent for updated research reports on each prediction marketsoctagon-docs — search, octagon-docs-read, octagon-docs-list, and octagon-docs-refreshWindows — 1. Download the Node.js installer: - Go to https://nodejs.org/ and download the LTS version for Windows. 2. Run the installerprediction_markets_history — Fetches historical data for a prediction market event ticker with optional pagination and time filtersThe server is distributed via npm as octagon-mcp, so most clients can run it without a manual build step. Add it to your MCP client's configuration and restart the client to pick it up — the copy-paste configs for Claude Desktop, Claude Code and Cursor are on this page.
Before the server will start you need to supply one environment variable: OCTAGON_API_KEY. Keep credentials in your client's env block or a secrets manager rather than committing them.
Before installing or running Octagon MCP, you need to have npx (which comes with Node.js and npm) installed on your system.
Developer-tool servers are usually the first ones people connect, because they turn "help me with this code" into an assistant that can actually read the repo and act on it. Octagon sits in that group, and the shape of its toolset — Multi, octagon-prediction-markets, octagon-docs among others — tells you what it is really for. Worth comparing against the other developer tools servers in this directory before you commit to one, since several overlap in scope but differ sharply in setup cost and permissions.
