Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

    const child = spawn(cmd, args, { cwd: opts.cwd, stdio: opts.quiet ? 'ignore' : 'inherit' });
    encoding: 'utf8', env: { ...process.env, PATH: `${dir}:${process.env.PATH}`, TEST_COUNT: path.join(dir, mode),
…olbar"><button id="step-undo" class="text-button">Undo</button><button id="step-redo" class="text-button">Redo</button><select id="step-add" aria-label="Add step"><option value="">+ Add step</option><option value="assert_visible">Assert visible</option><option value="assert_text"…
  assert.doesNotThrow(() => new Function(body), 'renderer inline script does not parse');
Object.assign(process.env, { API_KEYS: 'owner,other', OYA_OPERATOR_TOKEN: 'operator', OYA_PROFILE_SECRET: 'test-control-api', OYA_DATA_DIR: directory, OYA_STUCK_COMMAND_MS: '300' });
Sends data to a third-party sink ui/next.config.ts:24
const DEV_TUNNEL_ORIGINS = ["*.ngrok-free.app", "*.ngrok.app", "*.trycloudflare.com"];

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

This endpoint answered with an authorization challenge. The server is running, but it did not say what kind of credentials it expects.

Oya Browser — questions

Answers built from our own checks of this server.

Why is there no tool list for Oya Browser?
The server answered our handshake with an authorization challenge, so it is running — but it will not describe its tools to an anonymous client. To see them you need to connect with your own credentials. We record it as alive, not as broken: 100.0% of checks in the last 24 hours got a reply.
Is Oya Browser working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 530 ms. The bar chart above shows every period we have measured.
How do I connect Oya Browser?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address. You will need your own credentials: it refuses anonymous clients.
Does Oya Browser need an API key?
Yes. Every time we knock, Oya Browser answers with an authorization challenge instead of its tool list — that is how we know it is running and gated rather than broken. Bring your own credentials and it will talk.
How fast is Oya Browser?
It answers our handshake in 530 ms on average, which is faster than 27% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is Oya Browser open source?
We cannot say either way: written in JavaScript and 109 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
