Get details of an enumeration including all literals
AI agents call get_enumeration 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 queries enumeration definitions and their literal values from a SysML XMI model. It is a read-only operation with no side effects, consistent with other query tools on the server (find_classes, get_class_details, list_enumerations). The blast radius of misuse is minimal—an AI agent could retrieve unwanted model details but cannot modify, execute, or delete data.
From the tool's definition Tool name 'get_enumeration' and description 'Get details of an enumeration including all literals' indicate retrieval of enumeration metadata. No modification, execution, or destructive operations are implied.
Attacks that exploit this kind of access
Get details of an enumeration including all literals. 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 get_enumeration: 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.
get_enumeration 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_enumeration 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_enumeration. 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_enumeration 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.
