Build a Bazel tvOS target (tvos_application, tvos_extension, etc.).
AI agents invoke bazel_tvos_build to trigger actions in XcodeBazelMCP. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.
This tool executes a build operation on external code/targets, which is characteristic of the Execute category. While building itself is reversible (artifacts can be cleaned), the tool invokes external processes whose side effects (compiled binaries, intermediate build artifacts, potential side effects from build scripts) depend on the arguments provided.
From the tool's definition The tool "bazel_tvos_build" invokes the Bazel build system to compile and link tvOS application targets. Building is an external operation that triggers code compilation, linking, and artifact generation—effects that depend on the target argument and Bazel…
Documented attack patterns abuse exactly the kind of access bazel_tvos_build 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_tvos_build:
{
"version": "1",
"default": "deny",
"tools": {
"bazel_tvos_build": {
"limits": [
{
"counter": "bazel_tvos_build_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}bazel_tvos_build 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.
Free to start. No card required.
Build a Bazel tvOS target (tvos_application, tvos_extension, etc.). It is categorised as a Execute tool in the XcodeBazelMCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the XcodeBazel MCP server in PolicyLayer and add a rule for bazel_tvos_build: 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_tvos_build is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the bazel_tvos_build 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_tvos_build. 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_tvos_build 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.
