get_requisites
AI agents call get_requisites to retrieve information from Scottylabs without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves course prerequisites/requisite data from a catalog system. It performs a read operation that queries existing data without creating, modifying, deleting, or executing external operations. The lack of description slightly reduces confidence, but the tool name and consistent pattern with sibling read tools indicate low risk.
From the tool's definition Tool name 'get_requisites' and server context indicate retrieval of prerequisite information from CMU course catalog. Sibling tools (get_course, get_course_fces, etc.) are all read operations.
Attacks that exploit this kind of access
get_requisites. It is categorised as a Read tool in the Scottylabs MCP Server, which means it retrieves data without modifying state.
Register the Scottylabs MCP server in PolicyLayer and add a rule for get_requisites: 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 Scottylabs. Nothing to install.
get_requisites 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_requisites 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_requisites. 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_requisites is provided by the Scottylabs MCP server (shivendoo123/scottylabs_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
