AI agents call ReadFiles to retrieve information from Mcp Wcgw without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves file contents without modifying, executing, or deleting anything. It is a straightforward read operation with minimal security risk, appropriate for an AI agent to use when gathering context or information. The low severity reflects that reading files alone cannot damage systems or data, though sensitivity of file contents should be controlled via filesystem permissions outside this tool's scope.
From the tool's definition Tool name is 'ReadFiles' and description explicitly states 'Read content from one or more files' — a retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access ReadFiles gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Wcgw, and nothing reaches the server without passing your rules. This is the rule we recommend for ReadFiles:
{
"version": "1",
"default": "deny",
"tools": {
"ReadFiles": {}
}
}ReadFiles is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Read content from one or more files. It is categorised as a Read tool in the Mcp Wcgw MCP Server, which means it retrieves data without modifying state.
Register the Mcp Wcgw MCP server in PolicyLayer and add a rule for ReadFiles: 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 Wcgw. Nothing to install.
ReadFiles 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 ReadFiles 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 ReadFiles. 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.
ReadFiles is provided by the Mcp Wcgw MCP server (rusiaaman/wcgw). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
