ClawMoat | Run Agents On Your Main Computer. Don’t Run Them Naked.

New Anthropic suspended Fable's Claude access after Fable 5 jailbreak concerns. Read the ClawMoat angle →Agent seatbelt for the laptop era<br>Run agents on your main computer. Don’t run them naked.<br>Desktop agents are finally useful because they can touch your real files, real browser, real shell, real Gmail, and real workflows.<br>That also means one poisoned webpage, doc, email, MCP server, or background job can turn your assistant into a security incident. ClawMoat watches the work you are not watching.<br>Buy the agent seatbelt →Why the Fable 5 suspension mattersSee attack demo<br>$ npm install -g clawmoat

The shift<br>Agents moved from chat windows to your real machine.<br>The old threat model was hallucination. The new threat model is tool use on a laptop full of credentials, private files, browser sessions, and background tasks.<br>💻<br>Main computer access<br>Your agent works better when it can see the files you actually use. It also has a bigger blast radius.

🛠️<br>Shell and file tools<br>Helpful agents run commands, edit files, install packages, and call APIs. Those same tools can leak secrets or destroy state.

📬<br>Gmail, browser, Drive<br>Emails, webpages, docs, and tickets are untrusted input. Prompt injection stops being cute when it can trigger tool calls.

⏱️<br>Background jobs<br>Cron jobs and background sessions keep working after your attention moves elsewhere. That is exactly when guardrails matter.

The mechanism<br>ClawMoat is runtime security for desktop AI agents.<br>It scans the things that influence your agent, the actions your agent wants to take, and the data your agent is about to expose.<br>A chat app can hallucinate. A desktop agent can read your SSH keys, call curl, push to GitHub, message people, and keep running in the background.

What it catches<br>The bad stuff that happens after you give an agent tools.<br>💉<br>Prompt injection<br>Hidden instructions in webpages, READMEs, emails, Slack exports, PDFs, and support tickets.

🔐<br>Credential leaks<br>API keys, SSH keys, GitHub tokens, cloud credentials, npm tokens, and secrets in logs or outbound messages.

☠️<br>Dangerous tool calls<br>Destructive shell commands, sketchy curl pipes, sensitive file reads, suspicious network exfiltration.

📋<br>Audit gaps<br>No identity, no approval gates, no kill switch, no MCP policy, no trail for what the agent did while you were gone.

Buy protection<br>Free to scan. Paid when you want enforcement, alerts, and a real audit trail.<br>If an agent is already touching your laptop, the buy path should be obvious.

Before you run naked<br>10 checks before your agent lives on your laptop.<br>Use this as the quick mental model for Hermes, Claude Code, Codex, OpenCode, Cursor agents, local models, and MCP-heavy setups.

Know which directories the agent can read.<br>Know which commands it can execute without asking.<br>Scan untrusted webpages, emails, repos, and docs before the agent acts on them.<br>Block access to SSH keys, cloud creds, package tokens, browser cookies, and wallet material.<br>Scan outbound messages for secrets and PII.<br>Audit background sessions and cron jobs.<br>Set approval gates for destructive tools and external sends.<br>Review MCP server permissions before enabling them.<br>Keep an agent activity trail you can inspect later.<br>Install a seatbelt before you hand over the wheel.
