WHAT IT DOES

What bazel_ios_query does on XcodeBazelMCP

AI agents call bazel_ios_query to retrieve information from XcodeBazelMCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why bazel_ios_query is rated Low

This tool retrieves information about the Bazel build graph without modifying or executing anything. The explicit 'read-only' designation and query semantics indicate it only accesses data. Even though Bazel queries can be complex, the constraint to read-only access and workspace introspection keeps it firmly in the Read category with low blast radius.

From the tool's definition Tool name contains 'query' and description explicitly states 'read-only bazel query'

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs bazel_ios_query safely

PolicyLayer is an MCP gateway: it sits between your AI agents and XcodeBazelMCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For bazel_ios_query, this is the rule to start with:

bazel_ios_query Allowed

bazel_ios_query is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "bazel_ios_query": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect XcodeBazelMCP, apply this rule, and every bazel_ios_query call is checked against it from then on.

FAQ

Questions about bazel_ios_query

What does the bazel_ios_query tool do? +

Run a read-only bazel query in the configured workspace. It is categorised as a Read tool in the XcodeBazelMCP MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on bazel_ios_query? +

Register the XcodeBazel MCP server in PolicyLayer and add a rule for bazel_ios_query: 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.

What risk level is bazel_ios_query? +

bazel_ios_query is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit bazel_ios_query? +

Yes. Add a rate_limit block to the bazel_ios_query 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.

How do I block bazel_ios_query completely? +

Set action: deny in the PolicyLayer policy for bazel_ios_query. 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.

What MCP server provides bazel_ios_query? +

bazel_ios_query 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.
