WebMCP: checking… WebMCP spec ↗

Your denial. Your agent.
Overturned.

Health insurers deny about 1 in 5 in-network claims — and fewer than 1% of patients fight back, even though a large share of appeals succeed. Overturn is an appeals office built for both of you: your AI agent does the tedious legwork through WebMCP tools, while you stay in charge of every consequential step.

~1 in 5in-network claims denied
<1%of patients ever appeal
~40%+of appeals that are filed succeed
