OpenChrome

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.

What you can do

Navigate — navigate url=<url> opens a URL in a managed tab.
Read — read_page mode=dom returns a compact, ~5–15x token-cheaper serialization of the page. Use ref_N handles in follow-up actions.
Interact — interact, fill_form, form_input, act for clicking, typing, and high-level actions.
Screenshot — computer returns a screenshot of the current viewport.
Parallel lanes — open multiple tabs with oc_lane_create; work them concurrently with the same Chrome session and existing cookies.
Outcome contracts — oc_assert checks page state against a JSON contract (url equals, dom_count ≥ N, dom_text contains …) and returns pass / fail / inconclusive without guessing.
Skills — oc_skill_record / oc_skill_recall store and replay procedural memory across sessions.
Crawling — async crawl_start / crawl_status / crawl_cancel with cursor pagination.

Setup

npm install -g openchrome-mcp
openchrome setup               # Claude Code
openchrome setup --client codex   # Codex CLI

Restart your MCP client. Chrome auto-launches on the first tool call.

First tool by intent

Use this as the short routing card. The full catalogue remains in docs/agent/capability-map.md.

Intent	Start with	Fallback	Verify with
Open a URL	`navigate`	`tabs_create`	`read_page`
Read page facts	`read_page mode=dom`	`inspect` / `query_dom`	`oc_assert`
Find action targets	`oc_observe`	`find` / `oc_query`	`inspect`
Click or type	`interact`	`computer`	`oc_assert`
Verify success	`oc_assert`	`validate_page`	`oc_evidence_bundle`
Capture evidence	`oc_evidence_bundle`	`page_screenshot`	`oc_diff`
Debug a broken page	`validate_page`	`console_capture`	`oc_evidence_bundle`
Crawl or run background work	`crawl_start`	`crawl_status` / `crawl_cancel`	`oc_assert`
Repair runtime setup	`openchrome doctor`	`oc_doctor_report`	`openchrome check`

Default loop: navigate → read_page / oc_observe → interact → oc_assert → oc_evidence_bundle if the result is uncertain.

Use something else when:

You need a deterministic browser script without an MCP host agent: use Playwright or Puppeteer.
The user explicitly asks for a platform API or CLI: use that external tool.
The next step is irreversible: get the host/user confirmation gate first.

Key tools

Tool	Purpose
`navigate`	Open a URL
`read_page`	Read page content (dom / markdown / screenshot)
`interact`	Click / type on an element
`oc_assert`	Verify page state against a contract
`oc_lane_create`	Open a parallel tab lane
`oc_skill_record`	Store a reusable step sequence
`oc_skill_recall`	Retrieve steps for a domain
`crawl_start`	Start an async crawl job
`oc_evidence_bundle`	Snapshot DOM + screenshot + network + console
`oc_diff`	Compare two evidence bundles
