XcodeBuildMCP is an MCP server and command-line tool that gives coding agents tools for building and working on iOS and macOS projects. It supports workflows involving Xcode and xcodebuild, including project builds and device-related operations. Its catalogue add-ons provide agent instructions and connections for using the MCP server and CLI.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00034 | $0.00330 |
| Opus 5 | $0.00017 | $0.00165 |
| Sonnet 5 | $0.00007 | $0.00066 |
| Haiku 4.5 | $0.00003 | $0.00033 |
Grade A, and why
xcodebuildmcp-test-boundary-review scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
XcodeBuildMCP Test Boundary Review
Review guardrails for test isolation, scope, and contract validation.
Review scope
- Review-only by default.
- Do not edit product code unless the user explicitly requests implementation changes.
Files to inspect
src/**/__tests__/**src/test-utils/**src/snapshot-tests/**scripts/**/__tests__/**package.jsonxcodebuildmcp.com/app/docs/_content/testing.mdxxcodebuildmcp.com/app/docs/_content/contributing.mdx
Guardrails
- Unit tests inject command/filesystem/external dependencies.
- Unit tests do not call real
xcodebuild,xcrun, AXe, devices, or simulators. - Prefer testing logic/executor functions over handler wrappers unless testing runtime integration.
- Use existing mock executor helpers.
- Treat snapshot updates as contract changes requiring review.
- Do not add fake e2e/snapshot state to force test success.
- Avoid unsafe TypeScript suppressions.
Validation
- Run targeted Vitest command for touched tests.

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

xcodebuildmcp-test-boundary-review is a skill published in the GitHub repository getsentry/XcodeBuildMCP (6,336 stars, last pushed yesterday), licensed MIT. It adds 34 tokens to every session and 330 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
