List available data files in the project data directory.
AI agents call list_data_files to retrieve information from MCP Tabular Data Analysis Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or enumerates existing files without creating, modifying, or deleting data. It is a read-only directory listing operation with minimal security risk.
From the tool's definition Tool name 'list_data_files' and description 'List available data files in the project data directory' indicate a query/retrieval operation with no data modification or side effects.
Attacks that exploit this kind of access
List available data files in the project data directory. It is categorised as a Read tool in the MCP Tabular Data Analysis Server MCP Server, which means it retrieves data without modifying state.
Register the MCP Tabular Data Analysis Server MCP server in PolicyLayer and add a rule for list_data_files: 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 MCP Tabular Data Analysis Server. Nothing to install.
list_data_files 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_data_files 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_data_files. 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_data_files is provided by the MCP Tabular Data Analysis Server MCP server (k02d/mcp-tabular). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
