mcp-chrome

Chrome MCP Server is a Chrome extension-based Model Context Protocol (MCP) server that exposes your Chrome browser functionality to AI assistants like Claude, enabling complex browser automation, content analysis, and semantic search.

Runs with mockssource: GitHubTypeScriptMITcommit f48e71751e00

TypeScript, MIT licensed.

mcp-chrome runs, with stand-ins for the services it depends on. An Argusic agent installed it in 8 minutes and hit 3 errors and fixed every one without help on a clean machine with no GPU, and the whole session was recorded.

The monorepo builds successfully (packages/shared, app/chrome-extension, app/native-server), all 642 tests pass, the CLI responds to help/doctor commands, and the MCP stdio server starts without errors.

What the agent ended up with on a clean machine, in its own words. How this is measured

Measured by Argusic on a fresh machine every time. Every number links to its evidence. Argusic Score 92 of 100 (the mean of this project's run scores).

What was measured

From the run that decided this verdict. Every line is a recorded value, not an estimate.

Time lost to each failure while testing mcp-chrome, drawn from the recorded run
Every bar is a failure the agent recorded, with the time it cost. Drawn from this run, not from anywhere else.

What went wrong, in the agent's own words

The agent's own words, worst first, never rewritten into advice.

  • System Node.js v18.19.1 is below the project's requirement of Node >= 20, preventing pnpm install and builds2 minutes
  • pnpm 12 blocks build scripts (better-sqlite3, esbuild, sharp, etc.) by default, failing pnpm install2 minutes
  • Original jest.config.js with ts-jest fails to resolve .js extension imports (NodeNext module resolution) and coverage thresholds block tests from running2 minutes

What was not measured

The other half, so you can see exactly how far this evidence goes. A gap is printed as a gap and never filled in.

How the result was proved
runs before 2026-09-07 did not record the command used to check the result
Peak GPU memory
this ran on a CPU machine, so there was no GPU to sample
Behaviour over a long run
each attempt uses the smallest documented settings and a fixed time budget, so this measures whether it runs, not how it holds up under load
Behaviour against real services
this run was verified against stand-in services only

Replay the whole session, every command from a clean machine to this point.

How it was tested

One agent, one container, no human help. It installs the project the way its own documentation says to, runs it, and fixes what breaks. Everything below is recorded as it happened: the terminal session, the log and the exact commit. The full method.

Strengths and limits

Measured facts, not opinions. How this is written.

What went well

  • Recovered from all 3 errors without a human stepping in, which says the failures are documented well enough to solve.
  • Licensed MIT, as reported by its host.
  • Measured 3 times, so the result is not a one-off.

What did not, or is not known

  • Only reached a running state against stand-in services, so nothing here proves it works against the real ones.
  • Took 8 minutes to install, slower than the median of the 5 comparable projects Argusic has measured.

Of the 6 TypeScript projects Argusic has installed and timed, mcp-chrome was the 4th fastest to reach a running state, and 5 of 6 reached one at all.

Questions

Does mcp-chrome run?
mcp-chrome runs, with mocks standing in for external services. Argusic installed and launched it on a clean machine in 8 minutes, hitting 3 errors on the way, and recorded the session.
How did Argusic test mcp-chrome?
On a fresh, disposable machine, with every command recorded and the repository pinned at commit f48e71751e00. 3 attempts are recorded, and the full method is on the methodology page.
What did it cost to test mcp-chrome?
The run that produced this verdict cost $0.07: real compute and model cost, not a list price per million tokens. It is recorded on that run's page.
How long does mcp-chrome take to install?
8 minutes in the run that decided this verdict, from a clean machine to a running state. That is one measured attempt, not an average.
Does mcp-chrome need a GPU?
Not to start. Argusic reached a running state on a machine with no GPU.
What goes wrong when installing mcp-chrome?
3 things broke in the recorded run, and 3 were fixed without human help. Each one, and the time it cost, is listed on this page.
How does mcp-chrome compare with the alternatives?
Of the 6 TypeScript projects Argusic has installed and timed, mcp-chrome was the 4th fastest to reach a running state, and 5 of 6 reached one at all.
Where is the evidence for mcp-chrome?
All 3 recorded runs are on this page, each linking to its full log and terminal recording, stored with a sha256 fingerprint so it cannot be quietly altered.
