Check a single PHP file against WordPress Coding Standards.
AI agents call wpcs_check_file to retrieve information from WPCS MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and analyzes coding standards violations in a single PHP file. It produces diagnostic output (findings/violations) but does not modify files, execute code, delete data, or commit financial transactions. The action is a static code analysis read operation similar to linting. No side effects occur beyond generating a report of issues found.
From the tool's definition Tool name 'wpcs_check_file' and description 'Check a single PHP file against WordPress Coding Standards' indicate it performs analysis and reporting on code quality without modifying files or executing arbitrary operations.

PolicyLayer is an MCP gateway — it sits between your AI agents and WPCS MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for wpcs_check_file:
{
"version": "1",
"default": "deny",
"tools": {
"wpcs_check_file": {}
}
