Glass: MCP server, setup and security

What Glass does

According to its repository: “Drive native GUI apps under development: launch, screenshot, read the accessibility tree, inject input, tail logs and diff frames on desktop, Android and iOS.”

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. Glass is listed under Terminal and OS, a category of 115 servers in the directory, where it ranks #97 by stars.

Topics declared by the repository: cross-platform, developer-tools, native-apps, rust, sandbox, tools.

Installing and connecting Glass

No package or remote server is declared in the official MCP registry: you install it from source, following the repository README.

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: Rust. Listed systems: macOS, Windows, Linux.

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 Glass:

• System access: the Terminal and OS 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 June 8, 2026, the fixed-width/glass repository has 20 stars and 0 forks, with 18 open issues. It has more stars than 38% of the servers in the directory. It received changes this month. Version published in the registry: 1.8.0 (September 20, 2026).

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