Oya Browser: MCP server, setup and security

What Oya Browser does

According to its repository: “Real Chrome for agents: start a browser, read pages as numbered markdown, click, type, hand off.”

An MCP server gives an AI agent extra tools it calls during the conversation: the agent reads their description, decides to use them and gets the result back. Oya Browser is listed under Browser automation, a category of 109 servers in the directory, where it ranks #33 by stars.

Topics declared by the repository: ai-agents, browser-automation, browser-infrastructure, cdp, headless-chrome, playwright.

Installing and connecting Oya Browser

Distribution modes declared in the official MCP registry:

• remote server (streamable-http): you connect to it by URL, with nothing to install locally

Like any MCP server, you declare it in your client's configuration (Claude Desktop, Claude Code, Cursor, VS Code, Codex…): a name, the command that starts it or its URL, and any environment variables. The client then starts it and lists its tools. Project language: TypeScript.

Security: what to check

An MCP server runs code with the rights you give it, and the model reads its tool descriptions: a malicious or compromised server can hijack the agent. Read the code, or pick a maintained and widely used server, before connecting it.

Points found for Oya Browser:

• System access: the Browser automation category gives the agent control over files, a terminal, code or a browser. A booby-trapped instruction in content the agent reads (prompt injection) can then turn into an action.
• No licence: without a licence the code is not legally reusable, even if it is public. Avoid it in a company setting without the author's agreement.

Good practice: grant only the rights needed (least privilege), require human approval for irreversible actions, and run the AI agent security check.

Project activity and maintenance

Created on March 15, 2026, the OyadotAI/oya-browser repository has 351 stars and 282 forks, with 0 open issues. It has more stars than 85% of the servers in the directory. It received changes this month. Version published in the registry: 1.0.206 (October 22, 2026).

Stars measure attention, not quality: a recent, heavily promoted project can collect them fast, while a useful but niche server will have few.
