localsend-cli

localsend-cli is a skill for Claude Code, Codex from lsendapp/lsend-cli. It costs 48 tokens per session (952 once invoked), scanned B, original, Apache-2.0.

A command-line tool for sending and receiving files between devices on the same local network, compatible with the LocalSend app.

In plain words
What is it for?
Use it to find LocalSend peers, send files to a device IP, or start a one-time file-receiving server.
Why use it?
It gives coding agents a non-interactive way to discover nearby devices and transfer files, with machine-readable output.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

localsend-cli scanned grade B with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

A mod that escalates privileges can change anything on the machine, not only the project.

lsend CLI (agent workflow)

Non-interactive file transfer compatible with the LocalSend app.

Before running

  1. Install the prebuilt binary (don't compile from source — agents don't need a Rust toolchain). Auto-detects arch and OS:
    curl -L https://github.com/lsendapp/cli/releases/latest/download/lsend-$(uname -m | sed 's/x86_64/x86_64/;s/aarch64/aarch64/')-$(uname -s | tr A-Z a-z | sed 's/darwin/apple-darwin/;s/linux/unknown-linux-musl/').tar.gz \
      | tar xz \
      && sudo install lsend /usr/local/bin/
    lsend --version   # verify
    
    Windows: download lsend-x86_64-pc-windows-msvc.zip (or -aarch64-), extract, add the folder to PATH. macOS binaries are signed + notarized, so no Gatekeeper warning.
  2. Read focused docs offline: lsend agent or lsend agent send
  3. Use --json, piped stdout, or LSEND_NO_TUI=1 for machine-parseable output
  4. Close whatever holds port 53317 (e.g. the LocalSend app, another lsend receive) before receive
  5. Keep port 53317 for receive — alternate --port breaks multicast discovery; the LocalSend app and default scan will not see this device

Device alias

lsend alias show --json
lsend alias regenerate --json
lsend alias set "My Laptop" --json

Persisted in ~/.config/lsend/alias.txt. The global --alias flag overrides for one command only.

Discover devices

lsend scan --json --timeout 5000

Parse .devices[].ip from the JSON object. Prefer IP over alias for send.

Send files (preferred path)

lsend send <IP_FROM_SCAN> /path/to/file --json --no-scan
echo "hello" | lsend send <IP_FROM_SCAN> --text --json --no-scan
lsend send <IP_FROM_SCAN> --message "hello" --json --no-scan
lsend send <IP_FROM_SCAN> --clipboard --json --no-scan
  • --no-scan avoids a slow implicit rescan when the target is an alias
  • Add --pin if the receiver requires a PIN
  • --text reads UTF-8 from stdin; --message sends inline text; --clipboard sends plain clipboard text

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

localsend-cli is a skill published in the GitHub repository lsendapp/lsend-cli (5 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 48 tokens to every session and 952 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it B with 2 findings (asks for root, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
