Connect Claude to a live options-analytics API over MCP (the 2-endpoint gotcha)
The article discusses how to connect Claude to a live options-analytics API over MCP, highlighting the importance of selecting the correct endpoint. It outlines two main options for authentication: OAuth and API key. The piece provides detailed instructions for both methods to ensure successful integration.
- ▪FlashAlpha offers two MCP endpoints with the same tool catalogue but different authentication methods.
- ▪The OAuth method provides a cleaner setup, allowing Claude to call tools without manual key handling.
- ▪For clients using older builds, the API key method requires registering the URL and providing the key in each chat.
