About
MCP server for CostKits: live healthcare procedure cost estimates and provider pricing.
Security Report
5.2
Moderate5.2Moderate RiskA well-architected healthcare cost API MCP server with solid security practices. API key authentication is properly required for sensitive operations and stored via environment variables. Code is clean, input validation uses Zod schemas throughout, and the server safely delegates all business logic to a remote API. Minor quality observations around error handling and logging do not materially impact security. Supply chain analysis found 3 known vulnerabilities in dependencies (0 critical, 3 high severity). Package verification found 1 issue.

CostKits MCP Server
Give Claude, ChatGPT, Cursor, and other MCP clients access to live US healthcare cost data.
CostKits provides procedure cost estimates, patient out-of-pocket calculations, provider pricing, insurance coverage rules, and medical bill analysis using hospital-transparency and CMS data rather than model memory.
Ask healthcare cost questions in natural language. CostKits supplies the structured data and calculations.
A thin Model Context Protocol server for the CostKits API.
What can an agent do with CostKits?
Ask questions such as:
- "What would a colonoscopy cost in Connecticut?"
- "How much would I owe if I have $500 left on my deductible and 20% coinsurance?"
- "Compare MRI prices from providers near Dallas."
- "Does this procedure commonly require prior authorization?"
- "Do these medical bill line items show possible duplicate or unbundled charges?"
- "Resolve 'knee scan' to the correct procedure and estimate the cost."
The MCP server selects the appropriate CostKits API tools and returns structured healthcare cost data the model can explain to the user.

Quick start with Claude Desktop
1. Get a free API key
Create a key at costkits.com/api-keys.
You can test the installation without a key using the demo_estimate tool.
2. Add the MCP server
Add this to claude_desktop_config.json (Settings → Developer → Edit Config):
{
"mcpServers": {
"costkits": {
"command": "npx",
"args": ["-y", "@costkits/costkits-mcp"],
"env": {
"COSTKITS_API_KEY": "ck_your_key_here"
}
}
}
}
3. Restart Claude Desktop
Restart Claude Desktop so it reloads the MCP configuration.
4. Try a prompt
What would a colonoscopy cost me in Connecticut if I have $500 left on my deductible and 20% coinsurance?
The server uses MCP stdio transport and can be used with compatible MCP clients. A tested configuration example is provided for Claude Desktop in examples/claude-desktop-config.json.

Designed for reliable agent workflows
- Self-correcting errors — API errors include an
agent_hintthat tells the model what to call next. A typo'd procedure name becomes a resolve-and-retry, not a dead end. - Transparent estimates — responses include estimate ranges (p25/p50/p75), data sources, data vintage, and model version.
- Structured procedure resolution — agents can translate user language into supported procedure identifiers before estimating costs.
- Minimal sensitive data — bill analysis requires codes and amounts, not names, member IDs, or dates of birth.
- Deterministic insurance math — deductible, coinsurance, copay, and out-of-pocket calculations are performed by the API rather than improvised by the model.
Privacy and data handling
CostKits tools do not require patient names, member IDs, dates of birth, or medical-record identifiers.
For bill analysis, send only the billing codes, descriptions, and amounts needed for analysis. Do not send protected health information.
