A modern, secure command-line password manager written in Go. Uses age for encryption with built-in MCP server support for AI agent integration.

> Safety Notice: Symaira Vault manages sensitive secrets. Use at your own risk, keep tested backups of your vault, and verify recovery before relying on it for critical credentials.

Features

• Modern Encryption: age (X25519 + ChaCha20-Poly1305)
• TOTP Support: Store and generate TOTP codes
• Clipboard Auto-Clear: Automatic clearing after timeout
• Autotype: Cross-platform automatic password entry (macOS, Linux, Windows)
• Secret Execution: Run commands with vault secrets injected as environment variables
• Session Caching: OS keyring with 15-minute TTL
• Git Integration: Automatic commits and sync
• Multi-User Vaults: age recipients for shared access
• MCP Server: stdio and HTTP for AI agent integration with scoped token management
• MCP Slash Commands: add-credential, rotate-credential, find-and-use, share-credential — guided workflows surfaced as slash commands in Claude Code, OpenCode, Hermes
• Native Secure-Input Dialog: cross-platform popups (macOS osascript, Linux zenity/kdialog, Windows Get-Credential) for collecting credentials from agents without exposing them in chat
• Cross-Platform: macOS, Linux, Windows, FreeBSD

Quick Start

# Initialize vault
symvault init

# Add a password
symvault add github
# or non-interactive:
symvault set github.password --value "mysecretpassword"

# Add TOTP metadata
symvault add github --totp-secret JBSWY3DPEHPK3PXP --totp-issuer GitHub

# Retrieve (auto-copies to clipboard with 45s timeout)
symvault get github.password --clip

# Autotype password into focused application (macOS/Linux/Windows)
symvault get github.password --autotype

# Show entry details, including the current TOTP code when configured
symvault get github

# List and search
symvault list
symvault find mybank

# Generate secure passwords
symvault generate --length 32 --symbols
symvault generate --store newaccount.password --length 20 --symbols

# Session management
symvault unlock   # cache passphrase
symvault lock     # clear cache
symvault auth status
symvault auth set touchid      # macOS Touch ID unlock
symvault auth set passphrase   # passphrase-only unlock

# Interactive Terminal UI
symvault ui

# Recipients for multi-user vaults
symvault recipients list
symvault recipients add age1...

# Git sync
symvault git pull
symvault git push

# Secret execution (injects vault secrets as env vars)
symvault run --env API_KEY=api.kimi-key -- curl -H "Authorization: Bearer $API_KEY" https://api.example.com

# Backup/Restore
symvault backup ~/backups/symvault-$(date +%Y%m%d).tar.gz
symvault restore ~/backups/symvault-20260427.tar.gz

Backup archives contain encrypted vault files, identity material, config, and MCP tokens. Protect them like the vault itself and test restore before relying on backups.

Migration from other managers

Symaira Vault can import from 1Password, Bitwarden, pass, and CSV exports:

symvault import  
symvault import bitwarden ~/exports/bitwarden.json
symvault import pass ~/.password-store

See [docs/migration.md](docs/migration.md) for export steps, format details, and verification guidance.

MCP Server

Symaira Vault exposes an MCP server for AI agent integration:

# Stdio mode (recommended for local agents)
symvault serve --stdio --agent claude-code

# HTTP mode
symvault serve --port 8080

Use symvault agent install to generate ready-to-paste client config:

symvault agent install claude-code --config-only
symvault agent install claude-code --http --config-only
symvault agent install hermes --http --config-only

HTTP mode binds to 127.0.0.1 by default and uses bearer token authentication. Agents can use the MCP generate_totp tool to get current TOTP codes without receiving the stored TOTP secret.

Scoped Token Management (v2.2.0+): Create fine-grained access tokens for agents:

symvault agent token hermes new --tools list_entries,get_entry --expires 24h
symvault agent token list
symvault agent token hermes revoke 

For detailed agent setup, profiles, token management, and observability, see [docs/agent-integration.md](docs/agent-integration.md).

Configuration

Global config lives in the XDG config directory: $XDG_CONFIG_HOME/symaira-vault/config.yaml (default ~/.config/symaira-vault/config.yaml). Installs created before the XDG layout continue to read from the legacy ~/.symvault/config.yaml. See [config.yaml.example](config.yaml.example) for a commented starting point.

For the full configuration reference, see [docs/configuration.md](docs/configuration.md).

Environment Variables

• SYMVAULT_VAULT — Path to vault directory (default: $XDG_DATA_HOME/symaira-vault, i.e. ~/.local/share/symaira-vault; legacy installs use ~/.symvault)

Vault Structure

~/.local/share/symaira-vault/   # XDG data dir (legacy installs: ~/.symvault/)
├── identity.age      # Encrypted age identity
├── config.yaml       # Vault configuration

Security

• age encryption: X25519 + ChaCha20-Poly1305
• Passphrase never stored in plain text
• Session caching via OS keyring (15-minute TTL)
• Each entry individually encrypted
• Git history contains only ciphertext
• HTTP MCP bound to 127.0.0.1 with bearer token auth
• No telemetry (see [SECURITY.md](SECURITY.md#privacy--telemetry))

Symaira Vault differentiators:

• Terminal-native: Designed for keyboard-driven workflows without GUI dependency
• Modern encryption: age instead of GPG — simpler key management, no web of trust
• MCP-ready: Native AI agent integration via Model Context Protocol with scoped tokens and audit logging
• Zero telemetry: No analytics, no cloud dependency, no account required
• Built-in utilities: TOTP, autotype, secret execution, and password generation without external tools
• Git-native: Automatic sync with full version history of encrypted entries

> Security note on AI agent chat sharing: Pasting passwords into chat interfaces exposes secrets in plaintext chat history, model training logs, and provider databases. Unlike Symaira Vault's MCP integration — which keeps credentials encrypted and uses scoped tokens with audit logging — chat sharing provides no access control, rotation, or revocation capabilities.

Dependencies

• Go 1.26.4 or later
• filippo.io/age — encryption
• spf13/cobra — CLI framework
• zalando/go-keyring — OS keyring

Testing

# Run all tests with race detector (recommended for local validation)
make test

# Run tests without race detector (faster, for quick iteration)
make test-fast

# Run specific package tests
go test ./internal/vault/... -v

Tests include the Go race detector by default via make test to catch concurrency issues early. Use make test-fast when iterating quickly and you want a faster feedback loop without the race detector penalty.

Some tests are skipped automatically:

• Slow tests (-short flag): Flow and binary e2e tests skip in short mode. Run without -short to execute them.
• Headless CI: Tests requiring the OS keyring (session caching) skip when no keyring backend is available (e.g., containerized or headless CI). These are environment-dependent and not failures.
