BeyondTrust EPM Server

A Model Context Protocol (MCP) server for managing BeyondTrust Endpoint Privilege Management (EPM) through Claude Desktop and other MCP clients.

Features

• 🔐 Policy Management: Create, read, and manage EPM policies and applications
• 📋 Computer Management: List, authorize, and organize managed endpoints

🚀 Quick Start

Prerequisites

• Python 3.14 or higher
• uv package manager
• Claude Desktop (or another MCP client)
• BeyondTrust EPM instance with API credentials

Installation

1. Clone the Repository

git clone https://github.com/wesharris222/btepmmcp.git
cd btepmmcp

2. Install Dependencies

uv sync

This installs:

• httpx - HTTP client for EPM API
• mcp - Model Context Protocol SDK
• pefile - PE file parser for file inspection

3. Get Your EPM API Credentials

From your BeyondTrust EPM console:

1. Navigate to Configuration → API Registration
2. Create a new API client
3. Copy the following values:
   • Base URL: https://[your-subdomain]-services.pm.beyondtrustcloud.com
   • Client ID: Your API client ID (GUID)
   • Client Secret: Your API client secret

4. Configure Claude Desktop

Windows: Edit %APPDATA%\Claude\claude_desktop_config.json

macOS: Edit ~/Library/Application Support/Claude/claude_desktop_config.json

Linux: Edit ~/.config/Claude/claude_desktop_config.json

Add this configuration:

{
  "mcpServers": {
    "beyondtrust-epm": {
      "command": "uv",
      "args": [
        "--directory",
        "C:/path/to/btepmmcp",
        "run",
        "bt_epm_mcpv1.py"
      ],
      "env": {
        "BT_EPM_BASE_URL": "https://YOUR-SUBDOMAIN-services.pm.beyondtrustcloud.com",
        "BT_EPM_CLIENT_ID": "your-client-id-here",
        "BT_EPM_CLIENT_SECRET": "your-client-secret-here"
      }
    }
  }
}

Important: Replace the following:

• C:/path/to/btepmmcp → Actual path where you cloned the repo
• YOUR-SUBDOMAIN → Your EPM subdomain
• your-client-id-here → Your API client ID
• your-client-secret-here → Your API client secret

5. Restart Claude Desktop

Close and reopen Claude Desktop to load the MCP server.

6. Verify Installation

In Claude Desktop, try:

List all EPM policies

If configured correctly, Claude will use the MCP server to retrieve your policies!

🔒 Security & Safety

File Inspection Safety

The inspect_file_for_policy tool is 100% safe:

✅ Never executes files - Only reads metadata
✅ Read-only operations - No file modifications
✅ Static analysis only - Parses PE structures without running code
✅ Industry-standard library - Uses trusted pefile library
✅ Cross-platform - Works on Windows, Linux, macOS

See FILE_INSPECTION_README.md for details.

API Security

• Uses OAuth 2.0 client credentials flow
• Credentials stored in Claude Desktop config (local only)
• HTTPS communication with BeyondTrust EPM API
• Token auto-refresh with expiration handling

🐛 Troubleshooting

"Missing required environment variables"

Problem: Server can't find API credentials

Solution: Check your claude_desktop_config.json:

1. Verify the path is correct
2. Ensure all three env vars are set
3. No typos in variable names
4. Restart Claude Desktop after changes

"Import pefile could not be resolved"

Problem: Dependencies not installed

Solution:

cd /path/to/btepmmcp
uv sync

"File not found" when inspecting files

Problem: Relative paths or incorrect path format

Solution: Use absolute paths:

• Windows: C:\\Program Files\\App\\app.exe (double backslashes)
• Linux/Mac: /usr/bin/app

"HTTP Error 401 Unauthorized"

Problem: Invalid API credentials

Solution:

1. Verify credentials in EPM console
2. Check Base URL format (must include https://)
3. Ensure client has proper permissions

"HTTP Error 405 Method Not Allowed"

Problem: Incorrect API endpoint (fixed in v1)

Solution: Update to latest version:

git pull origin main

MCP Server Not Loading

Problem: Claude Desktop can't find the server

Solution:

1. Check absolute path in config is correct
2. Verify uv is in your PATH
3. Check Claude Desktop logs:
   • Windows: %APPDATA%\Claude\logs\
   • macOS: ~/Library/Logs/Claude/
   • Linux: ~/.config/Claude/logs/

💡 Tips & Best Practices

Policy Creation

1. Inspect files first: Use inspect_file_for_policy to get accurate metadata
2. Use publisher matching: More flexible than hash matching for updates
3. Test with small groups: Verify policies before wide deployment

File Inspection

1. Always use absolute paths: Avoid path resolution issues
2. Review extracted properties: Not all files have all metadata
3. Combine criteria: Use publisher + product name for best results

Security

1. Protect API credentials: Never commit config files with real credentials
2. Use least privilege: Create API clients with minimum required permissions
3. Review audit logs: Monitor MCP server actions in EPM audit logs
