AI agents call get_form_fields to retrieve information from Kintone MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only retrieves metadata about form fields in a Kintone app. It has no side effects—it does not create, modify, delete, or execute any operations. The low severity reflects minimal blast radius: an AI agent misusing this tool could only read field structure information, which is generally non-sensitive configuration data that does not directly expose sensitive records or enable destructive actions.
From the tool's definition Tool name 'get_form_fields' and description explicitly state it retrieves/queries form field information ('フォームフィールド情報を取得します' = 'retrieves form field information'). No modification, deletion, or execution of code/commands occurs.
Documented attack patterns abuse exactly the kind of access get_form_fields 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 get_form_fields:
{
"version": "1",
"default": "deny",
"tools": {
"get_form_fields": {}
}
}get_form_fields is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Register the Kintone MCP Server MCP server in PolicyLayer and add a rule for get_form_fields: 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.
get_form_fields is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_form_fields 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 get_form_fields. 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.
get_form_fields 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.
