Retrieves the current state of a folder, including its contents which can be sheets, reports, or other folders
AI agents call get_folder 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.
The tool performs a read-only operation that queries and retrieves folder metadata and contents from Smartsheet. There are no side effects, data modifications, or destructive actions. This is a straightforward data retrieval operation with minimal blast radius if misused by an agent—it would simply expose existing folder structure and contents the agent already has access to.
From the tool's definition Tool name 'get_folder' and description 'Retrieves the current state of a folder, including its contents' clearly indicate data retrieval without modification.
Attacks that exploit this kind of access
Retrieves the current state of a folder, including its contents which can be sheets, reports, or other folders. 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_folder: 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_folder 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_folder 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_folder. 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_folder 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.
