Run intelligent zero-configuration onboarding wizard to detect project type, generate configuration, verify tools, and validate setup
AI agents invoke onboarding_wizard to trigger actions in MCP DevTools Server. 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 performs automated setup and configuration generation which constitutes code/file execution with side effects. While it may also read project state ('detect project type'), the primary function is executing an onboarding process that generates and validates configuration. The effects depend on project context and could create files, modify settings, or install tools.
From the tool's definition Tool description states it will 'generate configuration, verify tools, and validate setup' and 'run intelligent' processes.
Documented attack patterns abuse exactly the kind of access onboarding_wizard gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MCP DevTools Server, and nothing reaches the server without passing your rules. This is the rule we recommend for onboarding_wizard:
{
"version": "1",
"default": "deny",
"tools": {
"onboarding_wizard": {
"limits": [
{
"counter": "onboarding_wizard_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}onboarding_wizard 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.

Run intelligent zero-configuration onboarding wizard to detect project type, generate configuration, verify tools, and validate setup. It is categorised as a Execute tool in the MCP DevTools Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the MCP DevTools Server MCP server in PolicyLayer and add a rule for onboarding_wizard: 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 MCP DevTools Server. Nothing to install.
onboarding_wizard 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 onboarding_wizard 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 onboarding_wizard. 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.
onboarding_wizard is provided by the MCP DevTools Server MCP server (rshade/mcp-devtools-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from MCP DevTools Server, 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.
