VibeDNA Vault MCP server

VibeDNA Vault MCP

Encrypted local vault for API keys. Your AI fetches keys on demand and scans code for leaks.

Vault keeps every API key, token and password in one encrypted file on your machine (Fernet, with the key derived from your master password by scrypt). The master password is read from your system keyring, or from VAULTMASTERPASSWORD on machines with no keyring. Your AI searches the vault and fetches the exact key it needs when it needs it, so keys stop getting pasted into chats. It exports an entry as .env lines, tracks rotation dates, keeps a usage log, ships entry templates for common services, and scans a project folder for keys left in plain text, reporting file and line.

A desktop window (vaultui.py) and a terminal CLI (vaultcore.py) open the same vault with no AI involved. There is no password reset: lose the master password and the file stays unreadable.

Tools (17)

Install

git clone https://github.com/marstudio360/vibedna-vault-mcp
cd vibedna-vault-mcp
python -m venv .venv
# Windows: .venv\Scripts\activate    mac/linux: source .venv/bin/activate
pip install -r requirements.txt
python vault_core.py init

Store the master password in your system keyring once, so the MCP server can open the vault:

python -c "import keyring; keyring.set_password('vibedna-vault','master', input('master password: '))"

Claude Code

claude mcp add vault --scope user -- /absolute/path/to/vibedna-vault-mcp/.venv/bin/python /absolute/path/to/vibedna-vault-mcp/server.py

Or in a project's .mcp.json:

{
  "mcpServers": {
    "vault": {
      "command": "/absolute/path/to/vibedna-vault-mcp/.venv/bin/python",
      "args": ["/absolute/path/to/vibedna-vault-mcp/server.py"]
    }
  }
}

On Windows the interpreter is .venv\Scripts\python.exe.

Cursor

Add the same mcpServers block to ~/.cursor/mcp.json (all projects) or .cursor/mcp.json (one project).

Claude Desktop

Add the same mcpServers block to claudedesktopconfig.json (Settings > Developer > Edit Config), then restart Claude Desktop.

INSTALL.md is a step-by-step guide written so you can paste it into an AI chat and let the AI do the install. It also covers the desktop window and the CLI.

Configuration

Shortened. The full README is on GitHub.
