Developer: MCP server, setup and security

What Developer does

According to its repository: “Developer tools for file editing, shell command execution and screen capture.”

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. Developer is listed under Coding agents, a category of 151 servers in the directory, where it ranks #122 by stars.

Installing and connecting Developer

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 Developer:

• Maintenance: no commit for 16 months. Possible flaws and protocol changes are no longer tracked.

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 May 26, 2025, the VertexStudio/developer repository has 20 stars and 8 forks, with 0 open issues. It has more stars than 38% of the servers in the directory. Last change 16 months ago.

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