validate_v2_playbooks
AI agents invoke validate_v2_playbooks to trigger actions in SousChef. 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.
The name suggests validating Ansible v2 playbooks. Validation typically involves parsing and executing checks against playbook files, which could invoke ansible-playbook --syntax-check or similar execution. Without a description, the exact behavior is unknown. Given the context (Chef-to-Ansible migration toolset), this is most likely a read/execute operation that runs validation logic.

PolicyLayer is an MCP gateway — it sits between your AI agents and SousChef, and nothing reaches the server without passing your rules. This is the rule we recommend for validate_v2_playbooks:
{
"version": "1",
"default": "deny",
"tools": {
"validate_v2_playbooks": {
"limits": [
{
"counter": "validate_v2_playbooks_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}validate_v2_playbooks 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.

validate_v2_playbooks. It is categorised as a Execute tool in the SousChef MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the SousChef MCP server in PolicyLayer and add a rule for validate_v2_playbooks: 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 SousChef. Nothing to install.
validate_v2_playbooks 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 validate_v2_playbooks 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 validate_v2_playbooks. 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.
validate_v2_playbooks is provided by the SousChef MCP server (kpeacocke/souschef). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from SousChef, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
