Search for any element by name across the entire model
AI agents call search_by_name 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 performs a read-only search across a SysML XMI model to locate elements by name. It retrieves information without creating, modifying, deleting, or executing any operations. The search capability is inherently non-destructive and non-mutating, making it a clear Read category classification.
From the tool's definition Tool is described as 'Search for any element by name across the entire model' - a search operation that retrieves/queries data with no side effects.
Attacks that exploit this kind of access
Search for any element by name across the entire model. 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 search_by_name: 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.
search_by_name 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 search_by_name 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 search_by_name. 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.
search_by_name 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.
Every MCP server has a record like this.
