Tap: MCP server, setup and security

What Tap does

According to its repository: “Compile browser automation into deterministic plans that run in your logged-in Chrome without runtime LLM calls, detecting drift when sites change.”

The Model Context Protocol (MCP) is a standard plug between an AI agent and an outside service: once the server is connected, its tools show up in the agent, which decides when to call them. Tap is listed under Browser automation, a category of 109 servers in the directory, where it ranks #83 by stars.

Topics declared by the repository: ai-agent, browser-automation, chrome-extension, playwright, automation, deterministic.

Installing and connecting Tap

Distribution modes declared in the official MCP registry:

• npm package (Node.js, usually started with npx)
• PyPI package (Python, started with uvx or pip)
• remote server (streamable-http): you connect to it by URL, with nothing to install locally

It works with any MCP-compatible client (Claude Desktop, Claude Code, Cursor, VS Code, Codex and most recent agents). You add one entry to the client's MCP configuration: server name, start command or URL, environment variables. Project language: TypeScript. Listed systems: macOS, Windows, Linux.

Security: what to check

Connecting an MCP server means installing software that talks straight to your agent: it runs with your rights and the model trusts its tool descriptions. The risk therefore depends on what it can touch and how far its code can be trusted.

Points found for Tap:

• 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.

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 April 3, 2026, the LeonTing1010/tap repository has 18 stars and 2 forks, with 1 open issues. It has more stars than 36% of the servers in the directory. Last change 3 months ago. Version published in the registry: 0.29.2 (August 1, 2026).

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