AI agents call bazel_ios_deps 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 queries and retrieves dependency metadata for a Bazel target. The term 'query' and 'dependencies' indicate a read-only retrieval of target information. There are no indications of side effects, code execution, data modification, or destructive operations. The blast radius is minimal—incorrect usage would simply return wrong or no dependency information to the user.
From the tool's definition Tool name 'bazel_ios_deps' and description 'Query direct dependencies of a Bazel target' indicate a query operation that retrieves dependency information without modifying or executing anything.

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_deps:
{
"version": "1",
"default": "deny",
"tools": {
"bazel_ios_deps": {}
}
}bazel_ios_deps 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.
Query direct dependencies of a Bazel target. 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_deps: 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_deps 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_deps 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_deps. 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_deps 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.
