AI agents call smartsheet_search 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 a query/search operation to locate and retrieve content from a Smartsheet document. No data is modified, created, deleted, or committed. The blast radius of misuse is minimal—an AI agent could search for sensitive information but cannot alter, delete, or destroy data. This clearly falls under the Read category.
From the tool's definition The tool name is 'smartsheet_search' and the description states it 'Search[es] for content in a Smartsheet'. Search is a read-only operation that retrieves data without modification, creation, deletion, or side effects.

{
"version": "1",
"default": "deny",
"tools": {
"smartsheet_search": {}
}

smartsheet_search is provided by the Smartsheet MCP Server MCP server (terilios/smartsheet-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Smartsheet MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
