OpenChrome is an MCP server that controls your real, already-logged-in Chrome through the CDP. It wraps the browser API with a hint engine, circuit breaker, auto-recovery runtime, and token-efficient page serialization.
navigate url=<url> opens a URL in a managed tab.read_page mode=dom returns a compact, ~5–15x token-cheaper
serialization of the page. Use ref_N handles in follow-up actions.interact, fill_form, form_input, act for clicking,
typing, and high-level actions.computer returns a screenshot of the current viewport.oc_lane_create; work them
concurrently with the same Chrome session and existing cookies.oc_assert checks page state against a JSON contract
(url equals, dom_count ≥ N, dom_text contains …) and returns pass / fail /
inconclusive without guessing.oc_skill_record / oc_skill_recall store and replay procedural
memory across sessions.crawl_start / crawl_status / crawl_cancel with
cursor pagination.npm install -g openchrome-mcp
