Reads the content of widgetResource.md file. This file contains widget-related information and documentation.
AI agents call read_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 performs a simple read operation on a static markdown file. It retrieves data without altering state, executing code, or causing irreversible changes. The stateless HTTP streaming server context and sibling tools (read_page_resource, ui-page-resource, ui-widget-resource) suggest a documentation/content serving role.
From the tool's definition Tool name 'read_widget_resource' and description 'Reads the content of widgetResource.md file' explicitly indicate retrieval of file contents with no modification or side effects.

Register the MCP Demo Server MCP server in PolicyLayer and add a rule for read_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.
read_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 read_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 read_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.
read_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.
