pod_repo_update

THE RISK

High Risk

This tool triggers an external operation (running 'pod repo update') that fetches and updates remote repository data. It modifies local CocoaPods spec repository clones, which is a network-dependent execution rather than a simple write, as it runs an external process/command with side effects depending on remote state.

HOW TO CONTROL POD_REPO_UPDATE

PolicyLayer is an MCP gateway — it sits between your AI agents and Xcode, and nothing reaches the server without passing your rules. This is the rule we recommend for pod_repo_update:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "pod_repo_update": {
      "limits": [
        {
          "counter": "pod_repo_update_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

pod_repo_update 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.

Create a free account and register Xcode — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

What does the pod_repo_update tool do? +

Updates the local clone of the CocoaPods spec repositories. It is categorised as a Execute tool in the Xcode MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on pod_repo_update? +

Register the Xcode MCP server in PolicyLayer and add a rule for pod_repo_update: 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 Xcode. Nothing to install.

What risk level is pod_repo_update? +

pod_repo_update is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit pod_repo_update? +

Yes. Add a rate_limit block to the pod_repo_update 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 pod_repo_update completely? +

Set action: deny in the PolicyLayer policy for pod_repo_update. 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 pod_repo_update? +

pod_repo_update is provided by the Xcode MCP server (xcode-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Xcode tool call.
