AI agents call setup_framework to retrieve information from Narrarium without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool is purely informational: it outputs setup instructions and npx commands for the user to run manually. It does not execute those commands, write any files, or interact with any system state. Classification is Read with low severity since misuse only results in the wrong instructions being shown.

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