AI agents call list_resources to retrieve information from Materio MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a pure discovery and retrieval tool. It queries a library catalog to enumerate available resources and return structured metadata. No side effects, data modification, code execution, or destructive operations are implied or described. The blast radius of misuse is minimal—an AI agent can only over-query or produce verbose listings, with no impact on system state or data integrity.
From the tool's definition Tool lists and discovers available educational resources without modifying data. Description states 'List all available educational resources' and 'discover what PDFs are available', with no mention of create, modify, delete, or execute operations.

Register the Materio MCP Server MCP server in PolicyLayer and add a rule for list_resources: 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 Materio MCP Server. Nothing to install.
list_resources 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_resources 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_resources. 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_resources is provided by the Materio MCP Server MCP server (materioa/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
