start_v2_migration
AI agents invoke start_v2_migration 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.
This tool appears to initiate a major version migration in enterprise infrastructure. Even though the description is empty, the name and server context indicate it executes automated processes that reconfigure or redeploy infrastructure resources.
From the tool's definition Tool name 'start_v2_migration' indicates initiation of a migration process. Given the server context (Chef-to-Ansible migration for enterprise infrastructure), this tool likely triggers automated infrastructure configuration changes, resource conversions, or…
Documented attack patterns abuse exactly the kind of access start_v2_migration gives an agent:
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 start_v2_migration:
{
"version": "1",
"default": "deny",
"tools": {
"start_v2_migration": {
"limits": [
{
"counter": "start_v2_migration_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}start_v2_migration 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.

start_v2_migration. 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 start_v2_migration: 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.
start_v2_migration 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 start_v2_migration 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 start_v2_migration. 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.
start_v2_migration 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.
