Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Run this in your terminal

claude mcp add --transport http nocticas https://app.nocticas.com/api/mcp --header 'x-nocticas-key: your-value'

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{

      "headers": {
        "x-nocticas-key": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

Common questions

Is Nocticas safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: x-nocticas-key

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.69.0) reached the registry 4 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Browser Use, Chrome DevTools MCP, MCP Server Browser

Nocticas E2E Gate — GitHub Action

Run a pinned Nocticas gate against a target URL on every push/PR, and fail the build on a red verdict. The browser runs on Nocticas's servers — this Action is a thin client that starts the run, polls for the verdict, and maps it to an exit code. No false greens: a harness error is never treated as a pass.

Quickstart

Author + pin a flow in Nocticas (agentic run → pin → export the deterministic step script as JSON).
Commit the gate to your repo, e.g. .nocticas/checkout-flow.json.
Add your key as a repo secret: NOCTICAS_API_KEY.
Add the workflow:

# .github/workflows/nocticas.yml

name: Nocticas E2E gate on: [pull_request, workflow_dispatch] jobs: verify: runs-on: ubuntu-latest # standard runner = free on public repos steps:

uses: actions/checkout@v4 # so the gate file is available
uses: Low-Latency-Labs/nocticas-action@v1 with: api-key: ${{ secrets.NOCTICAS_API_KEY }} gate: .nocticas/checkout-flow.json target: ${{ vars.PREVIEW_URL }} # your deployed preview/staging URL

A red verdict fails the job → blocks the PR/merge.

Inputs

Input	Required	Default	Description
`api-key`	yes	—	Your Nocticas API key (store as a secret).
`gate`	yes	—	Path to the pinned gate JSON (array of deterministic steps) in your repo.
`target`	yes	—	URL to test (e.g. the PR's preview deploy).
`api-base`	no	`https://app.nocticas.com/api`	Nocticas API base.
`timeout-seconds`	no	`300`	Max wait for a verdict.
`poll-seconds`	no	`3`	Poll interval.
`fail-on-error`	no	`true`	Treat a harness `error` (not a test fail) as a build failure. An unverified run is never a pass.

Outputs

Output	Description
`run-id`	The Nocticas run id (link it in your logs).
`verdict`	`passed` \	`failed` \	`error` \	`timeout`.

The gate file

A JSON array of deterministic steps — exactly what Nocticas produces when you *pin* a passing run. Example in examples/gate.example.json. Keeping it in your repo means your E2E test is version-controlled alongside the code it guards.

Don't commit real credentials. Point the gate at a staging/preview target and use a dedicated test account; Nocticas's built-in test inbox handles OTP/magic-link logins so you don't need to embed secrets in the gate.

Cost

Publishing this Action: free (public repo, no paid plan).
Running it (your customers): free on public repos with standard runners; within the monthly free-minutes allowance on private repos. It's a single thin job — seconds of runner time.
The browser run: billed in Nocticas credits — and deterministic/pinned runs are free within your monthly allowance, so gating every push typically costs nothing in credits.

Other CI systems (the recipe)

Not on GitHub? The same start → poll → exit logic is a portable script — see recipe.sh and examples/gitlab-ci.example.yml. The contract is just JSON over HTTP:

POST {api-base}/runs   { "mode":"deterministic", "target": "...", "script": [ ...gate... ] }   → { "id": "..." }

GET {api-base}/runs/{id} → { "status": "passed|failed|error|..." }

Header: `x-nocticas-key: <key>`. Exit non-zero unless `status == "passed"`.
