Reflex MCP is a local MCP server that drives your own Chrome from any MCP client. It returns compressed page snapshots and batched actions instead of full dumps, so your agent finishes the same task ~1.7x faster end to end on a fraction of the context, and never sends page content to our servers.
- ~2.8× fewer round trips
- Run browsers in parallel
- ~4× fewer tokens

How does Reflex MCP compare to Playwright MCP?
Reflex is the Playwright MCP alternative when every page look costs your context window: our head-to-head measured 6 tool calls and ~13K tokens across three flows versus 14 calls and ~56K for Playwright MCP, with 5 of 6 flows completed versus 3. Playwright MCP is free and better for iframes, network mocking, and Firefox/WebKit; Reflex wins on round trips, tokens, parallel sessions, and forensic failures.

Clients like Claude Desktop pay that snapshot cost on every look. Reflex compresses the page instead, so your agent keeps its context for the real work. Playwright MCP is free and better for iframes and other browsers; Reflex wins when every look costs you context. Full methodology and the reproduce command are on the benchmarks page.
Can I run multiple browsers in parallel?
Yes. Pass a session name on any Reflex tool call and it spins up a separate, isolated Chrome on demand, free. One agent can research ten sites at once; subagents can each drive their own browser. Playwright MCP shares a single browser, so parallel agents collide on the same tab. Reflex is the browser automation MCP built for parallel work from Claude Desktop, Cursor, and other MCP clients.

Agent-native
Built for agents, not just browsers.
- Failures you can act on
- When a step misses, Reflex sends back the closest matches, the console errors, and a screenshot, so your agent fixes it on the next try instead of guessing.
- Checks built into the action
- Reflex verifies the result inside the same call, so a task clearly succeeds or fails without an extra round trip to confirm.
- 0-token replay
- Save a task and re-run it anytime with no AI and no tokens. It repairs itself when the page changes.
Privacy
Your pages never leave your machine.
Reflex runs entirely on your computer: the MCP server, the browser, your logins, every page you visit. The only things that ever cross the network are your API key and a count of tool calls, so we can meter credits. We could not read your pages, sessions, or passwords if we wanted to; the architecture has no path for them.
Compare that to cloud browser products, where every page you visit renders on someone else's server.
