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 A, and why

yutori-computer-use scanned grade A with 0 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 today.

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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 132 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Computer Use

Run tasks on the user's visible Mac desktop with Yutori computer use, or drive a single app's window in the background while the user keeps working.

Setup

If the user has not set up computer use yet, ask them to run these commands in a real terminal:

uvx yutori-mcp login
uvx yutori-mcp computer-use setup

setup ends with the readiness checks and reports anything still missing. To re-check later, or when a run fails, use uvx yutori-mcp computer-use doctor.

Use the smoke test when validating a fresh install:

uvx yutori-mcp computer-use smoke

Requirements: macOS 15+, Python 3.10+, uvx, a Yutori API key with computer-use access, CuaDriver.app / cua-driver==0.28.0, and Screen Recording plus Accessibility permissions. The optional native reasoning overlay may require Xcode Command Line Tools.

Run a Task

In Claude Code, including Claude sessions hosted by Conductor, run the CLI through the Bash tool with stdout attached. This makes runner ready, each action #... line, shell-command previews, and the final result appear in the agent's live progress. Do not redirect the command to a file or call the MCP run_computer_use_task tool from these sessions: Claude's headless Agent SDK does not expose MCP progress or log notifications to its host.

For a foreground run:

uvx yutori-mcp computer-use run "$ARGUMENTS" --minutes 9 --max-steps 60

Run that as a foreground Bash call and set the Bash tool timeout slightly longer than the CLI's --minutes limit (Claude's foreground Bash timeout is capped at 10 minutes). Pass the task as one safely quoted argument and do not use eval.

For a longer run, start the same CLI command as a background Bash task without redirecting its output, then wait on it with TaskOutput in blocking intervals. Relay meaningful new action lines in progress updates between waits. The computer-use --minutes value remains the absolute run deadline.

For an app-specific task:

uvx yutori-mcp computer-use run "$ARGUMENTS" --app Safari --start-url https://example.com --minutes 9

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.
