Get widget(page fragment) resources. Returns information about all available admin widgets including their names, paths, descriptions, and prerequisites.
AI agents call ui-widget-resource to retrieve information from MCP Demo 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 queries metadata about available widgets. It has no side effects, does not create or modify data, does not execute code, and does not delete anything. The read-only nature and informational purpose classify it as a Read operation with low severity risk.
From the tool's definition Tool description states 'Get widget(page fragment) resources' and 'Returns information about all available admin widgets including their names, paths, descriptions, and prerequisites' — pure data retrieval with no modification, deletion, or execution…

Get widget(page fragment) resources. Returns information about all available admin widgets including their names, paths, descriptions, and prerequisites. It is categorised as a Read tool in the MCP Demo Server MCP Server, which means it retrieves data without modifying state.
Register the MCP Demo Server MCP server in PolicyLayer and add a rule for ui-widget-resource: 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 Demo Server. Nothing to install.
ui-widget-resource 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 ui-widget-resource 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 ui-widget-resource. 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.
ui-widget-resource is provided by the MCP Demo Server MCP server (jiawang1/mcp-demo). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
