download_files
AI agents call download_files to retrieve information from Moodle Student MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Despite empty description, the server is explicitly read-only and the tool name indicates file retrieval rather than creation, modification, or deletion. Downloading files a student can access is a read operation with minimal risk. Confidence is moderate due to missing description, but server context is decisive.
From the tool's definition Tool is hosted on a 'read-only' Moodle server and named 'download_files', consistent with sibling tools that are all read operations (get_*, list_*). Description is empty, but context strongly indicates retrieval of student-accessible files.
Attacks that exploit this kind of access
download_files. It is categorised as a Read tool in the Moodle Student MCP MCP Server, which means it retrieves data without modifying state.
Register the Moodle Student MCP server in PolicyLayer and add a rule for download_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 Moodle Student MCP. Nothing to install.
download_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 download_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 download_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.
download_files is provided by the Moodle Student MCP server (tcpassos/moodle-student-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
