List all enumerations with optional filtering
AI agents call list_enumerations to retrieve information from XMI MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays enumeration data from a SysML XMI model. The verb 'list' and the absence of any modification, deletion, or execution capabilities clearly place this in the Read category. The optional filtering is a query parameter, not a data-altering operation. No reversible writes, code execution, deletions, or financial transactions are involved.
From the tool's definition Tool name 'list_enumerations' combined with description 'List all enumerations with optional filtering' indicates data retrieval with no modification or side effects.
Attacks that exploit this kind of access
List all enumerations with optional filtering. It is categorised as a Read tool in the XMI MCP Server MCP Server, which means it retrieves data without modifying state.
Register the XMI MCP Server MCP server in PolicyLayer and add a rule for list_enumerations: 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 XMI MCP Server. Nothing to install.
list_enumerations 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_enumerations 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_enumerations. 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_enumerations is provided by the XMI MCP Server MCP server (mriiot/xmimcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
