Give your AI agent the power to fight insurance denials. One npx command connects Claude, ChatGPT, or any MCP client to 20 years of health system insider knowledge.
Two ways to integrate: MCP for AI agents, REST API for everything else. Both backed by the same denial analysis engine.
Add to your claude_desktop_config.json:
{
"mcpServers": {
"denialbot": {
"command": "npx",
"args": ["@coverageunlocked/denialbot-mcp"],
"env": {
"DENIALBOT_API_KEY": "cu_your_key_here"
}
}
}
}
Works with Claude Desktop, Claude Code, Cursor, Windsurf, and any MCP-compatible client.
Standard HTTP request from any language:
curl -X POST https://api.coverageunlocked.com/v1/appeal/generate \
-H "Authorization: Bearer cu_your_key" \
-H "Content-Type: application/json" \
-d '{
"denial_code": "CO-50",
"diagnosis": "Type 2 Diabetes",
"procedure": "CGM Device"
}'
Python, Node.js, Go, Java — any language that speaks HTTP.
Sandbox tier is free — 100 requests/month, 10 appeal letters. No credit card required.
