Lists the OSCAL profiles published alongside each ISM release: the five classification baselines (NC, OS, P, S, TS) and the three Essential Eight maturity levels (ML1, ML2, ML3).
AI agents call list_profiles to retrieve information from ISM MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only query operation that retrieves metadata about security profiles (classification baselines and maturity levels). It has no side effects, cannot modify data, execute code, or delete anything. The blast radius of misuse is minimal—an AI agent could only list available profiles, which is publicly available security information.
From the tool's definition Tool name is 'list_profiles' and description states it 'Lists the OSCAL profiles published alongside each ISM release', indicating a retrieval operation with no modification or execution capability.
Attacks that exploit this kind of access
Lists the OSCAL profiles published alongside each ISM release: the five classification baselines (NC, OS, P, S, TS) and the three Essential Eight maturity levels (ML1, ML2, ML3). It is categorised as a Read tool in the ISM MCP Server MCP Server, which means it retrieves data without modifying state.
Register the ISM MCP Server MCP server in PolicyLayer and add a rule for list_profiles: 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 ISM MCP Server. Nothing to install.
list_profiles 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 list_profiles 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 list_profiles. 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.
list_profiles is provided by the ISM MCP Server MCP server (rusticeagle/ism-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
