show
AI agents call show to retrieve information from HoloViz MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Based on the name and server context (visualization/charting), 'show' almost certainly retrieves and displays existing visualizations to the user without side effects. No modification, deletion, or execution of arbitrary operations is implied. Low severity because displaying data poses minimal risk.
From the tool's definition Tool name 'show' in a visualization server context typically renders or displays previously created content. Description is empty, limiting evidence.
Attacks that exploit this kind of access
show. It is categorised as a Read tool in the HoloViz MCP Server MCP Server, which means it retrieves data without modifying state.
Register the HoloViz MCP Server MCP server in PolicyLayer and add a rule for show: 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 HoloViz MCP Server. Nothing to install.
show 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 show 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 show. 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.
show is provided by the HoloViz MCP Server MCP server (sumayabee/holoviz-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
