FAQ

General

What blockchains does MUTX support?

Currently Solana.

Is MUTX open source?

No. The public product is distributed as binaries and container images.

Where is my data stored?

All wallet data is stored locally in SQLite databases under ~/.local/share/mutx/. Private keys are encrypted with AES-256-GCM.

Does mutx-mcp store wallet keys?

No. Wallet access stays in mutx-tui. The MCP server forwards requests to the TUI over a local Unix socket.

Does the TUI need to be running for MCP to work?

Yes. mutx-mcp depends on the TUI socket and cannot serve wallet operations by itself.

MCP

Can I run MCP remotely?

Yes, using HTTP mode:

mutx-mcp --mode http --bind 0.0.0.0:8000

The MCP endpoint is /mcp and the health endpoint is /health.

What still requires human approval?

Anything you do without an SLK. request_slk itself also always requires approval.

Can an SLK be revoked immediately?

Yes. Use slk_revoke or revoke it from the TUI.

TUI

Can I use Docker for the TUI?

Yes, but it must run with an interactive TTY and persistent volumes for config, data, and the shared socket directory.

Which tab should I watch during operation?

• Requests for MCP approvals
• DApps for WalletConnect proposals and sessions
• Logs for troubleshooting and audit context
