Verity

You can access Medicare coverage policies, prior authorization requirements, and medical code lookups through the Verity MCP Server. This server lets AI agents query CPT, HCPCS, ICD-10, and NDC codes; search Medicare policies; check if procedures require prior authorization; and compare coverage across jurisdictions, all via a lightweight MCP interface that integrates with your preferred client.

How to use

You interact with the Verity MCP Server by connecting through an MCP client using the standard MCP endpoints exposed by the server. You can perform code lookups to retrieve codes and their descriptions, search Medicare coverage policies (including LCDs, NCDs, and related articles), verify whether a procedure needs prior authorization, and compare coverage across MAC jurisdictions. You can also track changes to policies over time and explore specific coverage criteria blocks.

How to install

Practical installation steps to get the Verity MCP Server running on your machine.

Prerequisites you need before installing:

• Node.js 18 or higher

• A Verity API key (obtainable at verity.backworkai.com)

Install and run the server locally

# Step 1: Prepare your workspace
# Create or navigate to your project directory
cd verity_mcp

# Step 2: Install dependencies
npm install

# Step 3: Build the server
npm run build

# Step 4: Start the server (run in the foreground)
npm start

Configuration

Configure how your MCP client connects to Verity and provide your API key.

Claude Desktop configuration

To add the Verity MCP Server to Claude Desktop, update your configuration so Claude can launch the local server as an MCP endpoint.

{
  "mcpServers": {
    "verity": {
      "command": "node",
      "args": ["C:\\Users\\tyler\\OneDrive\\Desktop\\verity_mcp\\build\\index.js"],
      "env": {
        "VERITY_API_KEY": "vrt_live_YOUR_API_KEY_HERE"
      }
    }
  }
}

Replace YOUR_API_KEY_HERE with your actual Verity API key.

## Claude Code command

You can also add the MCP server via Claude Code using a direct command.

claude mcp add verity node C:\Users\tyler\OneDrive\Desktop\verity_mcp\build\index.js

Then set the environment variable:

set VERITY_API_KEY=vrt_live_YOUR_API_KEY_HERE

Replace YOUR_API_KEY_HERE with your actual API key.
