xc-mcp
XC-MCP delivers an intelligent MCP server for Xcode tooling with progressive disclosure and caching to prevent token overflow. It speeds workflows and boosts reliability in development 🐙
Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.
xcodebuild-version⚡ **Prefer this over 'xcodebuild -version'** - Gets Xcode version info with structured output and caching. Advantages over direct CLI: • Returns structured JSON (vs parsing version strings) • Cached results for faster subsequent queries • Validates Xcode installation first • Consistent response for…
xcodebuild-list⚡ **Prefer this over 'xcodebuild -list'** - Gets structured project information with intelligent caching. Advantages over direct CLI: • Returns clean JSON (vs parsing raw xcodebuild output) • 1-hour intelligent caching prevents expensive re-runs • Validates Xcode installation and provides clear err…
xcodebuild-showsdks⚡ **Prefer this over 'xcodebuild -showsdks'** - Gets available SDKs with intelligent caching and structured output. Advantages over direct CLI: • Returns structured JSON data (vs parsing raw CLI text) • Smart caching prevents redundant SDK queries • Consistent error handling and validation • Clean,…
xcodebuild-build⚡ **Prefer this over raw 'xcodebuild'** - Intelligent building with learning, caching, and performance tracking. Why use this instead of direct xcodebuild: • 🧠 **Learns from your builds** - Remembers successful configurations per project • 🚀 **Smart defaults** - Auto-suggests optimal simulators b…
xcodebuild-clean⚡ **Prefer this over 'xcodebuild clean'** - Intelligent cleaning with validation and structured output. Advantages over direct CLI: • Pre-validates project exists and Xcode is installed • Structured JSON responses (vs parsing CLI output) • Better error messages and troubleshooting context • Consist…
xcodebuild-get-detailsGet detailed information from cached build results
simctl-list🚨 **CRITICAL: Use this instead of 'xcrun simctl list'** - Prevents token overflow with intelligent progressive disclosure! Why this is essential over direct CLI: • 🔥 **Prevents token overflow** - Raw simctl output can be 10,000+ tokens, breaking conversations • 🎯 **Progressive disclosure** - Ret…
simctl-get-detailsGet detailed simulator information from cached simctl-list results with progressive disclosure
simctl-boot⚡ **Prefer this over 'xcrun simctl boot'** - Intelligent boot with performance tracking and learning. Advantages over direct CLI: • 📊 **Performance tracking** - Records boot times for optimization insights • 🧠 **Learning system** - Tracks which devices work best for your projects • 🎯 **Smart rec…
simctl-shutdown⚡ **Prefer this over 'xcrun simctl shutdown'** - Intelligent shutdown with better device management. Advantages over direct CLI: • 🎯 **Smart device targeting** - "booted" and "all" options vs complex CLI syntax • 🛡️ **Better error handling** - Clear feedback when devices can't be shut down • 📊 *…
list-cached-responsesList recent cached build/test results for progressive disclosure
cache-get-statsGet comprehensive statistics about all cache systems (simulator, project, response). Shows cache hit rates, expiry times, storage usage, and performance metrics across all caching layers. Useful for: - Monitoring cache effectiveness - Debugging performance issues - Understanding usage patterns - C…
cache-get-configGet current cache configuration settings
cache-set-config🎛️ **Cache Optimization** - Fine-tune XC-MCP's intelligent caching for your workflow. Why manage caching: • ⚡ **Performance tuning** - Longer caches = faster repeated operations • 🔄 **Fresh data control** - Shorter caches = more up-to-date information • 💾 **Memory management** - Balance speed …
cache-clearClear cached data to force fresh data retrieval
persistence-enable🔒 **Enable Opt-in Persistent State Management** - File-based persistence for cache data across server restarts. **Privacy First**: Disabled by default. Only usage patterns, build preferences, and performance metrics are stored. No source code, credentials, or personal information is persisted. Ke…
persistence-disable🔒 **Disable Persistent State Management** - Return to in-memory caching only. Safely disables file-based persistence and optionally clears existing cache data. After disabling, XC-MCP will operate with in-memory caching only, losing state on server restart. Use this when: • Privacy requirements c…
persistence-status🔒 **Get Persistence System Status** - Detailed information about persistent state management. Provides comprehensive status including: • Current enable/disable state • Cache directory location and permissions • Disk usage and file counts • Last save timestamps • Storage recommendations and health …
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
@modelcontextprotocol/sdk has cross-client data leak via shared server/transport instance reuse
Anthropic's MCP TypeScript SDK has a ReDoS vulnerability
Model Context Protocol (MCP) TypeScript SDK does not enable DNS rebinding protection by default
XC_MCP_CACHE_DIRXDG_CACHE_HOMETool annotations
No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
18/18 tools missing one or more hints — xcodebuild-version (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); xcodebuild-list (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); xcodebuild-showsdks (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +15 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
License file
No license file
Add a LICENSE file (MIT, Apache-2.0, etc.).
Tool test coverage
11/18 tools referenced in tests (61%)
Write tests that reference each tool by name so every tool has at least one test.
Shell command execution
2 calls in production code run through a shell (src/utils/command.ts:60, src/utils/validation.ts:7)
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Production dependencies are patched
0 critical, 3 high severity in production deps — @modelcontextprotocol/sdk@1.17.1 (high), @modelcontextprotocol/sdk@1.17.1 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
