Generate a new Bazel iOS or macOS project from a template. Creates MODULE.bazel, BUILD files, Swift sources, and config.
AI agents use bazel_scaffold to create or update resources in XcodeBazelMCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your XcodeBazelMCP environment.
This tool creates new files and project scaffolding (MODULE.bazel, BUILD files, Swift sources, config). It is a Write operation as it generates new content on disk. While it creates multiple files, this is reversible by deleting the generated project directory. Severity is medium due to the potential to overwrite existing files if run in an existing project directory.

Documented attack patterns abuse exactly the kind of access bazel_scaffold 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_scaffold:
{
"version": "1",
"default": "deny",
"tools": {
"bazel_scaffold": {
"limits": [
{
"counter": "bazel_scaffold_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}bazel_scaffold stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Generate a new Bazel iOS or macOS project from a template. Creates MODULE.bazel, BUILD files, Swift sources, and config. It is categorised as a Write tool in the XcodeBazelMCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the XcodeBazel MCP server in PolicyLayer and add a rule for bazel_scaffold: 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_scaffold is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the bazel_scaffold 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_scaffold. 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_scaffold 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.
