Obtiene la lista de páginas de una materia. Requiere course_id.
AI agents call pages 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 course page information through the Canvas REST API. The verb 'obtiene' (obtains/retrieves) indicates a read-only operation with no side effects. The tool belongs to the Read category as it queries data without creating, modifying, deleting, or executing external operations.
From the tool's definition Tool description states 'Obtiene la lista de páginas' (Gets the list of pages), which is a retrieval operation. The function signature and Canvas LMS context confirm this is a query-only tool that fetches page metadata without modification.

Register the Canvas MCP Server MCP server in PolicyLayer and add a rule for pages: 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.
pages 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 pages 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 pages. 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.
pages 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.
