// WHAT CAN GO WRONG

Write operations (boot_simulator, set_project_path, set_projects_base_dir) modify state. Without rate limits, an agent can make hundreds of changes in seconds — faster than any human can review or revert.

Execute tools (build_project, compile_asset_catalog, run_lldb) trigger processes with side effects. Builds, notifications, workflows — all fired without throttling.

// RECOMMENDED RULES

Rate limit write operations

boot_simulator:
  rules:
    - rate_limit: 30/hour

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

analyze_file:
  rules:
    - rate_limit: 60/minute

Controls API costs and prevents retry loops from exhausting upstream rate limits.

// FAQ

How do I prevent bulk modifications through Xcode? +

The Xcode server has 5 write tools including boot_simulator, set_project_path, set_projects_base_dir. Set rate limits in your policy file -- for example, rate_limit: 10/hour prevents an agent from making more than 10 modifications per hour. Intercept enforces this at the transport layer.

How many tools does the Xcode MCP server expose? +

18 tools across 3 categories: Execute, Read, Write. 8 are read-only. 10 can modify, create, or delete data.

How do I add Intercept to my Xcode setup? +

One line change. Instead of running the Xcode server directly, prefix it with Intercept: intercept -c xcode.yaml -- npx -y @xcode-mcp-server. Download a pre-built policy from policylayer.com/policies/xcode and adjust the limits to match your use case.
