Retrieves the current state of a sheet, including rows, columns, and cells
AI agents call get_sheet to retrieve information from Smartsheet MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs read-only access to sheet data. It queries and retrieves information without side effects, making it a straightforward Read category tool. The low severity reflects that unauthorized data access to a sheet is less critical than destructive or financial operations, though sensitivity depends on the sheet's content. Confidence is high due to clear retrieval semantics in both name and description.
From the tool's definition Tool name is 'get_sheet' and description explicitly states it 'Retrieves the current state of a sheet, including rows, columns, and cells' — a pure data retrieval operation with no modification, deletion, or execution capability.
Attacks that exploit this kind of access
Retrieves the current state of a sheet, including rows, columns, and cells. It is categorised as a Read tool in the Smartsheet MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Smartsheet MCP Server MCP server in PolicyLayer and add a rule for get_sheet: 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 Smartsheet MCP Server. Nothing to install.
get_sheet 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 get_sheet 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 get_sheet. 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.
get_sheet is provided by the Smartsheet MCP Server MCP server (thomaswtwrt/smar-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
