Show current session defaults, active profile, and config file settings.
AI agents call bazel_ios_show_defaults to retrieve information from XcodeBazelMCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool reads and displays session defaults and configuration settings. It performs no state changes, no code execution, and no side effects—it is purely informational retrieval. This aligns with the Read category for tools that query or fetch data.
From the tool's definition Tool name 'show_defaults' and description 'Show current session defaults, active profile, and config file settings' indicate a query operation that retrieves and displays configuration information without modifying or executing anything.
Documented attack patterns abuse exactly the kind of access bazel_ios_show_defaults 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_show_defaults:
{
"version": "1",
"default": "deny",
"tools": {
"bazel_ios_show_defaults": {}
}
}bazel_ios_show_defaults is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Show current session defaults, active profile, and config file settings. It is categorised as a Read tool in the XcodeBazelMCP MCP Server, which means it retrieves data without modifying state.
Register the XcodeBazel MCP server in PolicyLayer and add a rule for bazel_ios_show_defaults: 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_show_defaults is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the bazel_ios_show_defaults 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_show_defaults. 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_show_defaults 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.
