What list_patterns does on 3ilm
AI agents call list_patterns to retrieve information from 3ilm without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why list_patterns is rated Low
Despite the empty description, the tool name 'list_patterns' strongly suggests it retrieves or enumerates a collection of patterns, likely security or vulnerability patterns given the context of sibling tools. This is a passive read operation with no side effects. The absence of a description lowers confidence slightly, but the semantic meaning of 'list_' is reliable enough to classify confidently as Read.
From the tool's definition Tool name 'list_patterns' combined with sibling tools 'get_pattern_details' and 'search_vulnerabilities' indicates a query/retrieval operation. The 'list' prefix is characteristic of Read operations that enumerate data without modification.
Attacks that exploit this kind of access
The rule that runs list_patterns safely
PolicyLayer is an MCP gateway: it sits between your AI agents and 3ilm, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For list_patterns, this is the rule to start with:
list_patterns is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect 3ilm, apply this rule, and every list_patterns call is checked against it from then on.

Register the 3ilm MCP server in PolicyLayer and add a rule for list_patterns: 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 3ilm. Nothing to install.
list_patterns 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_patterns 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_patterns. 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_patterns is provided by the 3ilm MCP server (3ilm-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
