AI agents call smartsheet_list_sheets 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 retrieves information about sheets accessible to the authenticated user without creating, modifying, deleting, or executing any operations. It is purely a data retrieval/query operation with no side effects, fitting the Read category. Severity is low because listing sheets reveals metadata but does not expose sensitive cell data or enable destructive actions.
From the tool's definition Tool 'lists all sheets' and 'returns sheet summaries with IDs and metadata'; no modification, deletion, or execution occurs. The description explicitly states it enables discovery of 'available sheets' with pagination and filtering by modification date.

List all sheets the authenticated user has access to, with pagination support. Returns sheet name, ID, permalink, access level, and modification timestamps. Use this to discover available sheets before reading data from a specific one. Args: - page_size (number, optional): Results per page (default 100, max 100) - page (number, optional): Page number (default 1) - modified_since (string, optional): ISO 8601 date filter Returns: Array of sheet summaries with IDs and metadata. 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 smartsheet_list_sheets: 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.
smartsheet_list_sheets 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 smartsheet_list_sheets 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.
