Block Unapproved Egress
Block Unapproved Egress: what it does, its label on each agent, what it misses, and examples.
Catalog policy block-unapproved-egress, version 0.2.6, labelled blocks on Claude Code.
What it does
Best-effort guard on the tool channel: blocks sending data to a host outside the allowlist (.chock/egress-allowlist.txt, else a built-in registry list): curl/wget/iwr uploads, nc/socat/telnet, scp/rsync/sftp, ssh commands, aws/gsutil/az uploads, git push|remote add URLs, $(..)/$VAR in a URL or host. Asks on interpreter HTTP one-liners, gh gist/--body-file, curl --proxy/--resolve/Host:. Blocks ~/.curlrc writes. A floor, not a sandbox: other clients, runtimes, obfuscation.
On each agent
| Agent | Label | What it does there |
|---|---|---|
| Claude Code | Blocks | Refuses a matched shell command before it runs |
| Cursor | Blocks | Refuses a matched shell command before it runs. Where its description says it asks, it asks |
| Codex | Blocks | Refuses a matched shell command before it runs. Where its description says it asks, it refuses, because this client cannot prompt before a shell command. If the hook errors, the action goes through (not witnessed; the vendor's row is only partly live-run) |
| GitHub Copilot | Blocks | Refuses a matched shell command before it runs. Where its description says it asks, it asks in VS Code and refuses in Copilot CLI, because it cannot prompt there. If the hook errors, the action goes through (not witnessed; the vendor's row is only partly live-run) |
| Devin | Blocks | Refuses a matched shell command before it runs. Where its description says it asks, it refuses, because this client cannot prompt before a shell command. If the hook errors, the action goes through (vendor docs only, not witnessed) |
| Grok | Not graded | Not graded yet for Grok |
