Endform skills

Endform runs your existing Playwright suite in parallel, up to 10x faster, and helps you keep it healthy as it grows.

The endform skill lets your agent run your tests on Endform and find failing, flaky, and slow tests. It can then fix or quarantine them, or debug a test step by step in a live test.

Install

Claude Code

claude plugin marketplace add endformdev/skills
claude plugin install endform@endformdev

Claude Code doesn't update plugins from this marketplace automatically. To turn that on, run /plugin, go to Marketplaces, select endformdev, and select Enable auto-update. To update once, run claude plugin update endform@endformdev.

Codex

codex plugin marketplace add endformdev/skills
codex plugin add endform@endformdev

VS Code

In VS Code, enable chat.plugins.enabled, run Chat: Install Plugin From Source from the Command Palette, and enter https://github.com/endformdev/skills.

Other agents

Install the skill with skills.sh:

npx skills add endformdev/skills --skill endform

Pick your agents when prompted, or pass them with -a, for example -a claude-code. Add -g to install it for all your projects.

Use

Ask your agent, for example:

• "Set up Endform so our tests run on it in CI"
• "Which of our e2e tests are flaky?"
• "The checkout test only fails in CI, can you look into it?"
• "Quarantine the flaky search test so it stops blocking our PRs"

You can also call the skill directly: /endform in Claude Code and Cursor, /endform:endform in VS Code, and $endform in Codex.

MCP server

The Endform MCP server lets your agent query your test runs and debug failing tests on Endform. It comes in two versions:

	Local	Remote
Runs	On your machine, through npx	On Endform, at https://endform.dev/mcp
Best for	Coding agents working in your repository	Agents that can't run local commands, such as claude.ai
Sign-in	npx endform@latest login or ENDFORM_API_KEY	Your Endform account, in the browser
Organizations	Any you can access	All of yours, or one you choose when you connect
Live test debugging	Yes	No, it needs your local checkout

Local

The Codex and VS Code plugins add it for you. To add it in Claude Code:

claude mcp add --transport stdio --scope local endform -- npx -y endform@latest mcp

For Cursor and other agents, see the MCP server docs.

Remote

Add https://endform.dev/mcp as a remote MCP server in your agent and sign in with your Endform account. You choose all your organizations or a single one when you connect.

The Claude Code plugin adds it for you: run /mcp to sign in. To add it without the plugin, in Claude Code, add it and then run /mcp:

claude mcp add --transport http endform-remote https://endform.dev/mcp

In Codex:

codex mcp add endform-remote --url https://endform.dev/mcp
codex mcp login endform-remote

In VS Code, add this to .vscode/mcp.json and sign in when prompted:

{
  "servers": {
    "endform-remote": {
      "type": "http",
      "url": "https://endform.dev/mcp"
    }
  }
}

Using both

If you use the local server in one agent and the remote server in another, there's nothing else to set up: each agent has its own connection.

You can also add both to one agent by giving them different names, as the commands above do. It's usually better to pick one: local if the agent can run commands, remote if it can't.

Data and privacy

The plugin runs the Endform CLI from npm, which sends the Playwright tests you select, with what they need to run, and their results to Endform. See our privacy policy for more details.
