GTM API / Create antidetect browser

Provision ONE antidetect browser for the team. The main flow mints a fresh vendor (GoLogin) profile and pushes the resolved proxy into it, so supply exactly one proxy source: proxy_country_code is the default, custom_proxy_config routes that minted profile through a proxy the caller supplies (probed first, 422 custom_proxy_unreachable_* when dead, never with proxy_5g). Pick the branch yourself, never ask an end user for a sid. Bind an existing vendor_profile_id for the BYO-PROFILE path instead, with no proxy source: that profile carries its own. If no LinkedIn account signs in on it for 30 days, it is deleted and its seat freed. DANGEROUS: creates real vendor + proxy infrastructure. For SEVERAL browsers under ONE approval, do not call this per browser: author a mass action on /mcp/orchestration/mass-actions with scope {kind:"generate", count:N} and a plan of antidetect-browsers.create (+ antidetect-browsers.generate-cloud-browser-access-key), then read the connect links off each row when it finishes. Contract: - MCP tool create_antidetect_browser, registry package mcp.linkedin/antidetect_browsers, mount linkedin.browsers. - Operation create, response envelope create. - Flags: dangerous: the MCP layer gates it behind a preview/commit token, and the effect cannot be undone through this API.
