ExecBro: MCP server, setup and security
ExecBro is an MCP server published on GitHub that lets an AI agent inspect logs and interact with running React Native applications. Its repository has 80 stars and its last commit is from October 22, 2026, but it declares no licence.
What ExecBro does
According to its repository: “Gives AI agents eyes and hands into running React Native apps: logs, REPL, tap, screenshots”
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. ExecBro is listed under Code execution, a category of 32 servers in the directory, where it ranks #16 by stars.
Installing and connecting ExecBro
Distribution modes declared in the official MCP registry:
- npm package (Node.js, usually started with
npx)
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 ExecBro:
- System access: the Code execution 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 December 23, 2025, the igorzheludkov/execbro repository has 80 stars and 9 forks, with 0 open issues. It has more stars than 62% of the servers in the directory. It received changes this month. Version published in the registry: 2.18.1 (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.
