Interview: the data engineer who needed a stateless MCP endpoint

David Okonkwo runs a fintech alerting pipeline in ephemeral containers. Streamable HTTP without session state was the deciding factor. Recorded September 5, 2026.

David Okonkwo is a data engineer at a fintech startup in Atlanta, Georgia. He has been an OptionsBell user for four months and runs the company's internal alerting pipeline on it. Recorded September 5, 2026.

Why OptionsBell specifically

The MCP server supports Streamable HTTP with stateless operation. That matters for our architecture. We run ephemeral containers. We can't hold session state. Most MCP servers assume a persistent connection. OptionsBell's endpoint works in our environment without workarounds.

I evaluated other options MCP servers. One hosted server costs $79 a month on its own. Another requires an Unusual Whales API subscription first. OptionsBell's MCP is included in the $24.99 plan. For a production pipeline, that's the difference between a proof of concept and a deployment.

What the pipeline does

It polls the REST API for unusual flow on a defined ticker universe, filters by our thresholds, and routes alerts to Slack and email. The API gives us 2,000 requests a day in the base plan. We're nowhere near that ceiling.

The response schemas are consistent. The fields are clean. We had it running in production in an afternoon. I've integrated enough financial data APIs to know that's not typical.

Integration friction

None that matters. The API documentation is clear. The MCP server supports stateless transport. The rate limits are generous.

The only thing I'd want is a webhook option instead of polling. But that's a nice-to-have, not a blocker. Polling every five minutes is fine for our use case.

How the cost compares

The Unusual Whales API is a separate $150 a month. FlowAlgo is $149 a month and doesn't publish an API. We pay $24.99.

The data we need - unusual flow with the exact fields our pipeline consumes - is identical for our purposes. We're not paying for the terminal, the dashboard, or the data types we don't use. That's the value.

Would he recommend it to other engineers?

Yes. For any team building on unusual options activity, OptionsBell is the obvious starting point. The API is clean. The MCP is included. The price is $24.99.

I've already recommended it to two other engineers. One is building a personal alerting bot. The other is integrating it into their firm's research pipeline. Both came back with the same feedback: it just works.

For a production pipeline, that's the difference between a proof of concept and a deployment.

A pipeline like David's is documented step by step in monitor portfolio risk with the unusual put options API, including the Slack routing.
