Octagon MCP Server gives AI agents access to SEC filings, earnings call transcripts, financial metrics, stock market data, deep financial research, and prediction markets, covering 8,000+ public companies and 10,000+ active tickers.
Claude is Anthropic's AI assistant, available as a desktop app and in Cowork. It supports custom connectors, so it can call MCP servers directly from a chat.
This guide connects Octagon AI MCP to Claude Desktop through MewCP, so Claude Desktop can use Octagon AI MCP's 4 tools, like octagon-agent, octagon-deep-research-agent and octagon-prediction-markets-agent, without your Octagon AI MCP credentials ever reaching the app.
Octagon AI MCP signs in through managed OAuth. MewCP stores the token encrypted, refreshes it before it expires and injects it only at call time. Your agent never holds it, so it can never leak it.

Other clients
Octagon AI MCP works the same way in every client below. Pick yours for its own guide.
Free to start.
Scope access to the exact Octagon AI MCP tools and accounts you allow, work and personal side by side. Anything outside that scope is refused at call time, even when the model asks for it.
Each call is logged: what ran, on which account, and whether it worked. Failures come back structured, so the agent knows whether to retry instead of guessing.
Every app sits behind one secure MCP URL, and there is no server for you to deploy or keep running. Add an integration in the dashboard and it is live on the next call, with no config to change and no new credentials to wire up. Tools load only when a task needs them, so your agent stays fast and focused however many apps you connect.
In Claude, open Settings → Connectors, then choose Add custom connector.
Name it "mewcp" and paste the URL.
A browser window opens the first time the client connects. Sign in and approve access. No API key needed.
Start a new chat and ask: "List the tools you can use from MewCP." You should see your connected apps.
