Remote hands for coding agents: an MCP server that runs OpenCode / Claude Code / Codex work on a remote host over SSH, keeps credentials and the local machine closed, and audits everything

About farhand

Gives a coding agent hands on a remote machine and keeps its hands off the local one. https://farhand.cogflux.io

FarHand is an MCP server. Point OpenCode, Claude Code or Codex at it, and every command the model runs and every file it reads or writes happens on a remote host over your existing SSH setup. The local machine stays closed, with one exception you control: a list of local folders the model may look into and upload from. Nothing that looks like a credential is ever sent to the remote, and everything that happens is written to a local audit log.

That works, but the agent's provider keys and configuration have to live on the remote, and every agent needs its own way of doing it. FarHand keeps the agent — and its credentials — local, and gives every MCP-capable agent the same remote hands.

Local: macOS or Linux with OpenSSH. Remote: Linux with bash, timeout (coreutils), base64, an SFTP subsystem (default in sshd), and ideally ripgrep for remoteglob / remotegrep (both fall back to find / grep). Windows is not supported: FarHand relies on OpenSSH connection multiplexing over a Unix socket.

Prebuilt binary (no Rust needed) — one file into ~/.local/bin, checksum verified:

Or download farhand--.tar.gz from the releases page yourself, or cargo binstall farhand.

From source (Rust stable): cargo install --path crates/farhand puts farhand in ~/.cargo/bin; or cargo build --release and point FARHANDBIN at target/release/farhand.
