Get current number of columns
AI agents call gridstack_get_column 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.
This tool retrieves configuration metadata (column count) from an existing GridStack instance. It performs no modifications, deletions, or execution of arbitrary code. It is a simple state query operation with negligible blast radius if misused by an AI agent.
From the tool's definition Tool name 'gridstack_get_column' and description 'Get current number of columns' indicate a retrieval operation with no side effects. The verb 'get' combined with 'current number' clearly describes querying existing state.
Attacks that exploit this kind of access
Get current number of columns. 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_get_column: 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_get_column 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_get_column 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_get_column. 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_get_column 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.
