List all WebMCP tools available on the current page (both native and auto-synthesized)
AI agents call list_webmcp_tools to retrieve information from Webclaw without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries metadata about available WebMCP tools on a page. It performs information retrieval with no side effects—no code execution, data modification, deletion, or financial transactions. It is purely a discovery/enumeration mechanism, classifying as Read with low severity.
From the tool's definition Tool name 'list_webmcp_tools' and description 'List all WebMCP tools available on the current page' indicate a retrieval operation that enumerates available tools without modifying state or triggering external operations.

PolicyLayer is an MCP gateway — it sits between your AI agents and Webclaw, and nothing reaches the server without passing your rules. This is the rule we recommend for list_webmcp_tools:
{
"version": "1",
"default": "deny",
"tools": {
"list_webmcp_tools": {}
}
}list_webmcp_tools is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List all WebMCP tools available on the current page (both native and auto-synthesized). It is categorised as a Read tool in the Webclaw MCP Server, which means it retrieves data without modifying state.
Register the Webclaw MCP server in PolicyLayer and add a rule for list_webmcp_tools: 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 Webclaw. Nothing to install.
list_webmcp_tools 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 list_webmcp_tools 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 list_webmcp_tools. 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.
list_webmcp_tools is provided by the Webclaw MCP server (kuroko1t/webclaw). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Webclaw, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
