Model Context Protocol (MCP) for AI Agents (Node)

Integrate Keeper Secrets Manager into AI agents using Node

AI Agent Integration with Model Context Protocol (MCP)

Keeper Secrets Manager works with AI agents through the Model Context Protocol (MCP), enabling AI Agents to securely interact with specific vault folders. This integration provides a zero-trust architecture where AI agents are explicitly allowed to access designated information from the Keeper Vault.

The Model Context Protocol integration acts as a secure bridge between AI assistants and Keeper Secrets Manager. It allows AI tools to help you manage secrets while maintaining the highest security standards through human-in-the-loop confirmations for sensitive operations.

Key Benefits

Zero Trust Architecture: AI agents are assigned specific folders in the vault Human-in-the-Loop: Confirmation prompts for sensitive operations Enterprise Ready: Comprehensive audit logging and compliance features Multi-Platform: Works on Linux, macOS, and Windows

What Can AI Assistants Do?

With KSM MCP integration, AI assistants can help you:

Secret Operations

List secrets - Browse your accessible secrets Search secrets - Find secrets by title, URL, username, or other fields Retrieve secrets - Get specific secret values (with confirmation for unmasked data) Create secrets - Generate new secret entries Update secrets - Modify existing secret information Delete secrets - Remove secrets (with confirmation)

File Management

List attachments - View file attachments on secrets Upload files - Add file attachments to secrets Download files - Retrieve file attachments Delete files - Remove file attachments

Utilities

Generate passwords - Create secure passwords with customizable parameters Get TOTP codes - Retrieve current time-based one-time passwords Execute KSM notation queries - Use Keeper's notation system for complex operations Health checks - Monitor server status and connectivity

Setup and Installation

(1) Create Secrets Manager Application

From Keeper Secrets Manager, create an Application or use an existing application.

Create an Application and assign folders

(2) Create a Device Token

Discard the first Device token, and click on "Add Device" to generate a new Base64 configuration that will be provided to your AI agent.

Generate Base64 Token

(3) Configure the MCP Server

You have two options for providing your Keeper configuration:

Option A: Configuration File (Recommended)

Place your downloaded configuration file in one of these locations:

  • ~/.keeper/ksm-config.json (recommended)

  • ./ksm-config.json (in the current directory)

Option B: One-Time Token

If you have a one-time token instead:

export KSM_TOKEN="US:YOUR_ONE_TIME_TOKEN_HERE"

The server will use this token to generate and save a configuration file automatically.

(4) Test the Server

Run the server directly to test:

npm start

You should see: Keeper MCP server is running

Usage with MCP Clients

Claude Desktop

Add to your Claude Desktop configuration (~/Library/Application Support/Claude/claude_desktop_config.json):

{
  "mcpServers": {
    "keeper": {
      "command": "node",
      "args": ["/path/to/keeper-mcp-node/dist/index.js"]
    }
  }
}

Postman

  1. In Postman, go to the API Network tab

  2. Create or select an MCP request

  3. Configure the stdio connection:

    • Command: node

    • Arguments: /path/to/keeper-mcp-node/dist/index.js

Other MCP Clients

The server communicates via stdio, so you can integrate it with any MCP-compatible client by running:

node /path/to/keeper-mcp-node/dist/index.js

  • Check that the file has proper JSON formatting

  • Verify file permissions (should be readable by your user)

Error: Failed to initialize KSM

  • Verify your configuration file contains all required fields

  • Check that your application has access to the shared folders/secrets

  • Ensure your device hasn't been revoked in Keeper

Connection Issues

  • Verify you have internet connectivity

  • Check if your organization has IP restrictions enabled

  • Ensure your Keeper subscription includes Secrets Manager
