List all sheet tab names available from the loaded file.
AI agents call list_sheets to retrieve information from ERP-File MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only enumerates metadata (sheet names) from an already-loaded file. It retrieves information without creating, modifying, deleting, or executing any operations. The action is read-only and has negligible blast radius—knowing sheet names poses minimal security risk unless the sheet names themselves contain sensitive business logic or are confidential.
From the tool's definition Tool name 'list_sheets' and description 'List all sheet tab names available from the loaded file' indicate a query/retrieval operation with no modifications.
Attacks that exploit this kind of access
List all sheet tab names available from the loaded file. It is categorised as a Read tool in the ERP-File MCP Server MCP Server, which means it retrieves data without modifying state.
Register the ERP-File MCP Server MCP server in PolicyLayer and add a rule for 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 ERP-File MCP Server. Nothing to install.
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 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.
Set action: deny in the PolicyLayer policy for list_sheets. 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.
list_sheets is provided by the ERP-File MCP Server MCP server (sharpjsdev/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
