Get the inheritance chain for a class (parents and children)
AI agents call get_inheritance_hierarchy 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 only retrieves and explores structural relationships in a SysML model—it performs no mutations, deletions, code execution, or financial operations. The server is explicitly designed for 'querying and exploring' models, and this tool fits that pattern. The worst-case misuse is exposing metadata about class hierarchies, which poses minimal risk.
From the tool's definition Tool retrieves inheritance chain information (parents and children) for a class from an XMI model without modifying data.
Attacks that exploit this kind of access
Get the inheritance chain for a class (parents and children). 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_inheritance_hierarchy: 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_inheritance_hierarchy 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_inheritance_hierarchy 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_inheritance_hierarchy. 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_inheritance_hierarchy 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.
