load_data
AI agents call load_data 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.
The tool appears to retrieve or load data from storage or sources to support visualization creation. With no description provided, confidence is moderated, but the name and function within the visualization workflow indicate a read-only data retrieval operation with no side effects. Severity is low as data loading carries minimal risk of misuse compared to write, execute, or destructive operations.
From the tool's definition Tool name 'load_data' and sibling tools including 'get', 'search', 'list' suggest data retrieval operations. The server context (creating interactive visualizations) implies reading data for rendering.
Attacks that exploit this kind of access
load_data. 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 load_data: 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.
load_data 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 load_data 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 load_data. 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.
load_data 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.
