MOST DANGEROUS TOOLS
Critical Risk

The most dangerous XcodeBazelMCP tools

Destructive · High bazel_ios_clean The bazel_ios_clean tool, particularly with the expunge option, irreversibly deletes or removes data (build outputs and the entire output base). Destructive · Medium bazel_ios_agent_debug_log_clear The tool deletes debug log files, which is an irreversible destructive operation. Destructive · High bazel_ios_erase_simulator This tool permanently deletes all simulator state and configuration. Destructive · Medium swift_package_clean Cleaning build artifacts irreversibly deletes compiled outputs and cached build data.

80 of XcodeBazelMCP's 117 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control XcodeBazelMCP

PolicyLayer is an MCP gateway — it sits between your AI agents and XcodeBazelMCP, and nothing reaches the server without passing your rules. These are the rules we recommend:

Deny destructive operations
{
  "bazel_ios_agent_debug_log_clear": {
    "deny_if": [
      {
        "conditions": [],
        "on_deny": "Blocked by default. Requires approval."
      }
    ]
  }
}

Destructive tools should never be available to autonomous agents without human approval.

Rate limit write operations
{
  "bazel_scaffold": {
    "limits": [
      {
        "counter": "bazel_scaffold_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations
{
  "bazel_ios_last_command": {
    "limits": [
      {
        "counter": "bazel_ios_last_command_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

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

  1. Create a free account and register XcodeBazelMCP — nothing to install.
  2. Add these rules — paste them, or build them visually. Tune the limits to your setup.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.

Questions about XcodeBazelMCP

Can an AI agent delete data through the XcodeBazel MCP server? +

Yes. The XcodeBazelMCP server exposes 5 destructive tools including bazel_ios_agent_debug_log_clear, bazel_ios_clean, bazel_ios_erase_simulator. These permanently remove resources with no undo. PolicyLayer blocks destructive tools by default so they never reach the upstream server.

How do I prevent bulk modifications through XcodeBazelMCP? +

The XcodeBazelMCP server has 6 write tools including bazel_scaffold, bazel_toggle_workflow, swift_package_init. Set a rate limit in your policy -- for example, 10 calls per hour prevents an agent from making more than 10 modifications per hour. PolicyLayer enforces this at the gateway, before calls reach XcodeBazelMCP.

How many tools does the XcodeBazel MCP server expose? +

117 tools across 4 categories: Destructive, Execute, Read, Write. 37 are read-only. 80 can modify, create, or delete data.

How do I enforce a policy on XcodeBazelMCP? +

Register the XcodeBazel MCP server in PolicyLayer, apply the suggested rules above (adjust the limits to your use case), and point your AI client at the PolicyLayer proxy URL instead of the server directly. Your agents keep the same tools; PolicyLayer evaluates every call against policy before it executes. Nothing to install, live in minutes.

Enforce policy on every XcodeBazelMCP tool call.

Deterministic rules across all 117 XcodeBazelMCP tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
