验证输出文件 - 检查所有必需文件是否正确生成
AI agents call verify_output_files to retrieve information from JoyCode MCP Server - FOP Workflow Assistant without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool performs verification and checking of files—a read-only operation that queries state without side effects. It does not create, modify, delete, or execute code/commands. This is consistent with other sibling tools like 'get_output_directories' and 'get_file_naming_rules' which are information retrieval tools on this workflow automation server.
From the tool's definition Tool name 'verify_output_files' and description '验证输出文件 - 检查所有必需文件是否正确生成' (Verify output files - check whether all required files are correctly generated) indicate inspection/validation of existing files without modification, creation, or deletion.
Documented attack patterns abuse exactly the kind of access verify_output_files gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and JoyCode MCP Server - FOP Workflow Assistant, and nothing reaches the server without passing your rules. This is the rule we recommend for verify_output_files:
{
"version": "1",
"default": "deny",
"tools": {
"verify_output_files": {}
}
}verify_output_files is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Register the JoyCode MCP Server - FOP Workflow Assistant MCP server in PolicyLayer and add a rule for verify_output_files: 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 JoyCode MCP Server - FOP Workflow Assistant. Nothing to install.
verify_output_files 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 verify_output_files 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 verify_output_files. 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.
verify_output_files is provided by the JoyCode MCP Server - FOP Workflow Assistant MCP server (shaun888/easy-workflow). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
