AI agents use create_form_layout to create or update resources in Kintone MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Kintone MCP Server environment.
This tool creates or modifies configuration data (form layout) within a Kintone application. It is reversible—form layouts can be updated or deleted—and has no financial implications or destructive effects. It fits the Write category: it creates new structured data (the form layout configuration).
From the tool's definition Tool name 'create_form_layout' and description indicating automatic generation of form layout from field information.
Documented attack patterns abuse exactly the kind of access create_form_layout gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Kintone MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for create_form_layout:
{
"version": "1",
"default": "deny",
"tools": {
"create_form_layout": {
"limits": [
{
"counter": "create_form_layout_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_form_layout 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.

フィールド情報からフォームレイアウトを自動生成します. It is categorised as a Write tool in the Kintone MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Kintone MCP Server MCP server in PolicyLayer and add a rule for create_form_layout: 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 Kintone MCP Server. Nothing to install.
create_form_layout 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 create_form_layout 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 create_form_layout. 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.
create_form_layout is provided by the Kintone MCP Server MCP server (r3-yamauchi/kintone-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Kintone MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
