Zerocheck developer resources
Docs, the CLI, the local MCP server, and the files that agents read. Import a checklist in the web app or on your machine, then run the same tests in a hosted browser or in CI.
How Zerocheck works
The browser agent, test workflow, evidence and fit for your team.
Documentation
Setup, checklist import, the YAML format, runs, GitHub Actions, MCP, and data handling.
CLI
npx zerocheck import, run, and report. The same YAML on your laptop and in CI.
MCP server
npx zerocheck mcp starts a stdio server for coding agents such as Claude Code or Cursor.
zerocheck on npm
The CLI package on npm.
GitHub Actions
The generated workflow, JUnit and JSON reports, and one PR comment per pull request.
Pricing
One pilot plan, no per-seat charges.

Paste this into Claude Code or Cursor
After onboarding has provisioned your project, run this from your app's repository. The agent uses the MCP tools to write, run and fix one test; it cannot complete the browser sign-in for you.
Set up Zerocheck in this repository. Run `npm install --save-dev --save-exact [email protected]`, then `npx zerocheck login`, then `npx zerocheck init --url http://localhost:3000` and `npx zerocheck install`. Start the MCP server with `npx zerocheck mcp --project-dir <absolute path to this repository>` and add it to your MCP configuration. Then use its tools to write one test for the most important page in this app, run it, and fix the test until it passes without changing the expected outcome. Show me the drafted YAML and the result link before saving.Agent quickstart
Requires provisioned access, a configured environment and a running app. Import runs drafts before you review them; save reviewed definitions before running the suite. Read the complete quickstart.
npm install --save-dev --save-exact [email protected]
npx zerocheck login
npx zerocheck init --url http://localhost:3000 --github-actions
npx zerocheck install
npx zerocheck import release-checklist.md --env dev
# Review the draft, then replace DRAFT_ID with its identifier.
npx zerocheck import --draft DRAFT_ID
npx zerocheck validate
npx zerocheck run --env dev
