chrome-use — Network Interception

Intercept, mock, rewrite, block, and record network traffic on the page you're driving — all via the CDP Fetch domain (no proxy, no extra extension permission).

Mock responses & rewrite requests

network route intercepts matching requests via the CDP Fetch domain (no proxy, no extension permission). Three modes, verbs/fields mirror Playwright:

# Mock the RESPONSE (fulfill — the request never leaves the browser)
chrome-use network route "**/api/users" --body '{"users":[]}' --status 200 --content-type application/json
chrome-use network route "**/api/me" --body '{"vip":true}' --header X-From=mock

# Rewrite the outgoing REQUEST (continue with overrides — real response returns)
chrome-use network route "**/api/save" --method POST --set-header Authorization="Bearer test"
chrome-use network route "**/api/save" --set-body '{"x":1}'          # replace the request body
chrome-use network route "**/v1/*" --rewrite-url https://staging.example.com/v1/thing
