Connect Claude.ai to NexusTrade MCP

Add the NexusTrade server

https://nexustrade.io/api/mcp

On an individual Pro or Max account, open Customize, then Connectors. Choose + Add, then Add custom connector. Name it NexusTrade, paste the server URL shown above and choose Continue. Review detected authentication and continue. Choose Sign in now and Claude's published OAuth identity, then finish with Add and complete NexusTrade sign-in.

Sign in to your NexusTrade account

On Team or Enterprise, an owner first adds the Web connector in Organization settings, Connectors. Members then open Customize, Connectors and choose Connect. In a chat, use +, then Connectors to enable NexusTrade for that conversation.

Verify with a real read

Run this public read after sign-in. Match the company, filing form, date and SEC URL in the returned result.

If something doesn't work

If NexusTrade is absent from the client's server list, check that you saved the configuration in the selected project or profile. If it appears but requests sign-in, finish the client-specific OAuth step above. If a read returns an authorization error, reconnect to the intended NexusTrade account. Preserve the returned error instead of asking the agent to bypass authentication. A research conversation can request compute and backtests, which can consume credits. Historical results are simulations. Live-order workflows retain their existing application approval boundary.
