Obtiene los módulos (secciones) de una materia. Requiere course_id.
AI agents call modules to retrieve information from Canvas MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves module/section information from Canvas LMS for a given course. It is a read-only operation that queries existing course structure data without creating, modifying, deleting, or executing anything. The low severity reflects that unauthorized access would only expose course organizational structure, which is typically low-sensitivity educational content.
From the tool's definition Tool name 'modules' and description 'Obtiene los módulos (secciones) de una materia' (Gets the modules/sections of a subject) indicates a retrieval operation.

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