Cortex Context MCP Adapter

MCP (Model Context Protocol) adapter for Cortex Context integration.

Getting Started

Installation

You can use either pnpm or npm.

pnpm:

pnpm install @cortexguardai/mcp

npm:

npm install @cortexguardai/mcp

Important: How MCP Adapters Work

The MCP adapter communicates via stdin/stdout using the MCP protocol. When you run it directly from the command line, it will appear to “hang” - this is normal behavior. The adapter is waiting for MCP protocol messages from a compatible client.

Usage

With Claude Desktop (Recommended)

1. Configure your mcp.json file.

For pnpm users:

{
  "mcpServers": {
    "cortex-context": {
      "command": "pnpm",
      "args": [
        "dlx",
        "@cortexguardai/mcp@latest",
        "--token", "your-auth-token",
        "--project-id", "your-project-id"
      ]
    }
  }
}

For npm/npx users:

{
  "mcpServers": {
    "cortex-context": {
      "command": "npx",
      "args": [
        "@cortexguardai/mcp@latest",
        "--token", "your-auth-token",
        "--project-id", "your-project-id"
      ]
    }
  }
}

2. Restart Claude Desktop
3. The adapter will be available as a context source

Direct Command Line (for testing only)

pnpm:

pnpm dlx @cortexguardai/mcp --token  --project-id 

npx:

npx @cortexguardai/mcp --token  --project-id 

Note: When run directly, the adapter will start and then wait for MCP messages. This is expected behavior, not an error.

Testing the Adapter

To verify the adapter is working correctly, you can use the test client:

# From the project root
node test-mcp-client.js

This will spawn the adapter, send an MCP initialize request, and confirm it responds correctly.

Configuration Options

• --token, -t: Authentication token (required)
• --project-id, -p: Project ID to scope the adapter to (required)
• --timeout: Request timeout in milliseconds (default: 30000)
• --verbose, -v: Enable verbose logging (default: false)

Troubleshooting

“The adapter appears to hang”

This is normal! The MCP adapter uses stdin/stdout communication and waits for MCP protocol messages. It only responds when a compatible MCP client (like Claude Desktop) sends requests.

Schema Validation Errors

If you encounter invalid_literal errors expecting “object” in tool inputSchema:

• This was fixed in version 1.0.5+ by using explicit string literals in JSON Schema definitions
• Ensure you’re using the latest version:
  • pnpm add -g @cortexguardai/mcp@latest
  • npm install -g @cortexguardai/mcp@latest
• Rebuild the adapter if developing locally:
  • pnpm run build
