How to Set Up and Use MCPVault
MCPVault is a local, encrypted credential vault and MCP server that enables AI agents to securely manage and switch between multiple service accounts without storing secrets in plaintext config files or restarting the chat client. It wraps the APIs of Supabase, GitHub, Vercel, and Stripe with pre-built tool sets, using AES-256-GCM encryption to protect stored credentials and OS keyring integration for the master password. When an AI agent needs to switch from one account to another mid-conversation — for example, from a staging Supabase project to a production one — MCPVault handles the credential swap instantly through a tool call, keeping the workflow uninterrupted.
Prerequisites
- Node.js 20+ installed
- Access to one or more supported services: Supabase, GitHub, Vercel, or Stripe, with their respective API tokens or keys
- An MCP-compatible client such as Claude Desktop, Cursor, or Windsurf
- OS keyring support (macOS Keychain, Windows Credential Manager, or Linux Secret Service) for master password storage
Install MCPVault globally
Install the MCPVault CLI globally via npm.
npm i -g @elraian/mcpvaultInitialize the vault
Run the init command to create the encrypted vault file at ~/.mcpvault/vault.enc and set up the master password.
mcpvault initAdd service accounts to the vault
Use the 'add' command to add accounts for each service. MCPVault will prompt you for the credentials and encrypt them.
# Add a Supabase account
mcpvault add supabase
# Add a GitHub account
mcpvault add github
# Add a Vercel account
mcpvault add vercel
# Add a Stripe account
mcpvault add stripeRun the setup command
Run setup to generate the MCP server configuration for your installed MCP client.
mcpvault setupAdd MCPVault to your MCP client configuration
Add the MCPVault server entry to your claude_desktop_config.json or equivalent config file.
{
"mcpServers": {
"mcpvault": {
"command": "npx",
"args": ["-y", "@elraian/mcpvault", "serve"]
}
}
}Use account switching in your AI assistant
Ask your AI assistant to unlock the vault and switch between accounts. MCPVault will activate the selected account's credentials for all subsequent tool calls.

Example prompts for managing credentials and switching accounts with MCPVault.
- "Unlock the vault and list all stored accounts"
- "Switch to the Acme Corp Supabase account and list its projects"
- "Activate my personal GitHub account and list my repositories"
- "Show me all Vercel deployments under the staging account"
- "Switch to the production Stripe account and list recent charges"
- "What account is currently active for Supabase?"Troubleshooting MCPVault
Vault unlock fails or master password is not recognized
The vault uses OS keyring integration. On Linux, ensure the Secret Service daemon (e.g. gnome-keyring or kwallet) is running. If the keyring is unavailable, MCPVault may fall back to prompting for the password directly. Re-run 'mcpvault init' if the vault file is corrupted.
Tools for a specific service (e.g. Supabase) are not appearing
Ensure you have added an account for that service with 'mcpvault add supabase' and that an account is active. Run 'vault_status' through your AI assistant or 'mcpvault list' in the terminal to see registered accounts.
'@elraian/mcpvault' package not found by npx
Install globally first with 'npm i -g @elraian/mcpvault' and change the command in the config from 'npx' with args to the direct 'mcpvault' binary with 'serve' argument.
