Fetch a page's full content as Markdown.
AI agents call get_page to retrieve information from Libretexts without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and returns existing content from LibreTexts open textbooks without modifying, deleting, or executing any operations. It is a straightforward read operation with minimal risk even if invoked by an AI agent, as it only accesses publicly available educational material.
From the tool's definition Tool description states 'Fetch a page's full content as Markdown' - fetch is a read-only retrieval operation with no side effects.
Attacks that exploit this kind of access

Register the Libretexts MCP server in PolicyLayer and add a rule for get_page: 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 Libretexts. Nothing to install.
get_page 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 get_page 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 get_page. 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.
get_page is provided by the Libretexts MCP server (mubashir1osmani/libretexts-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
