Run an arbitrary LLDB command. Use for advanced debugging not covered by other tools.
AI agents invoke bazel_ios_lldb_command to trigger actions in XcodeBazelMCP. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.
LLDB is a low-level debugger that can execute arbitrary code, inspect and modify memory, and trigger side effects within running processes. Running arbitrary LLDB commands allows an AI agent to execute code whose effects depend entirely on the command arguments provided.
From the tool's definition "Run an arbitrary LLDB command" – the tool explicitly permits execution of arbitrary commands via the LLDB debugger, with no restrictions mentioned.
Documented attack patterns abuse exactly the kind of access bazel_ios_lldb_command gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and XcodeBazelMCP, and nothing reaches the server without passing your rules. This is the rule we recommend for bazel_ios_lldb_command:
{
"version": "1",
"default": "deny",
"tools": {
"bazel_ios_lldb_command": {
"limits": [
{
"counter": "bazel_ios_lldb_command_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}bazel_ios_lldb_command stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Run an arbitrary LLDB command. Use for advanced debugging not covered by other tools. It is categorised as a Execute tool in the XcodeBazelMCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the XcodeBazel MCP server in PolicyLayer and add a rule for bazel_ios_lldb_command: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches XcodeBazelMCP. Nothing to install.
bazel_ios_lldb_command is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the bazel_ios_lldb_command rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for bazel_ios_lldb_command. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
bazel_ios_lldb_command is provided by the XcodeBazel MCP server (xcodebazelmcp/xcodebazelmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from XcodeBazelMCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
