Load grid layout from JSON
AI agents call gridstack_load to retrieve information from GridStack MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The gridstack_load tool reads/loads a grid layout from JSON format. This is a read operation that retrieves configuration data. There are no side effects on the dashboard beyond rendering the loaded layout. No data is created, modified, deleted, or executed as a consequence of loading. This is a standard Read category operation with low severity—worst case, it loads an incorrect layout affecting only UI presentation.
From the tool's definition Tool name 'gridstack_load' and description 'Load grid layout from JSON' indicate retrieval and deserialization of existing layout data without modification.
Attacks that exploit this kind of access
Load grid layout from JSON. It is categorised as a Read tool in the GridStack MCP Server MCP Server, which means it retrieves data without modifying state.
Register the GridStack MCP Server MCP server in PolicyLayer and add a rule for gridstack_load: 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 GridStack MCP Server. Nothing to install.
gridstack_load 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 gridstack_load 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 gridstack_load. 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.
gridstack_load is provided by the GridStack MCP Server MCP server (raghavsharma-simpplr/gridstack-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
