Why this is BLOCK. The audit found 0 critical and 5 high findings; the most severe is Code injection at src/utils/axe-helpers.ts:204. Each finding is listed below with its file and line.

Why this page is still public. People search for this server by name. Hiding it would leave them with the README's word alone; here they see what the code does. We list it so you can decide, and we do not show connect commands for BLOCK servers.

Questions about XcodeBuild MCP server

What is the XcodeBuild MCP server?
A Model Context Protocol (MCP) server and CLI that provides tools for agent use when working on iOS and macOS projects.
What tools does XcodeBuild expose?
4 in total: 4 read-only, 0 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.
Is XcodeBuild safe to connect to an agent?
No — not without reading the findings first. The audit graded it D (64/100) and found 5 critical or high issues in the source. Each one is listed on this page with the file and line it is on.
What credentials does XcodeBuild need?
It reads GITHUB_TOKEN from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.
How does XcodeBuild run?
It speaks stdio, so it runs as a local process your client starts. It is published on npm as xcodebuildmcp at 2.7.0.
How current is this page?
The grade is for one exact copy of the source (51987d327c73), read on 2026-09-21. The repository is watched and re-audited when it changes.
I already installed XcodeBuild. What should I do?
Remove it from your client's MCP configuration, then rotate any API keys and tokens that were in your environment while it ran.
Can the verdict change?
Yes. The repository is watched and re-audited when its source changes. If the findings are removed the verdict updates, and the history on this page shows it.
