remove_guest
AI agents call remove_guest to permanently remove resources in Mofstructure — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The name 'remove_guest' strongly suggests it removes guest molecules from a crystal structure, which could be a destructive/irreversible modification of the structural data. However, since the description is empty, it's possible this operates on a copy or returns a modified structure without overwriting the original.
From the tool's definition Tool name 'remove_guest' implies removal/deletion of guest molecules from a MOF structure. Description is empty, providing no additional context.
Attacks that exploit this kind of access
remove_guest. It is categorised as a Destructive tool in the Mofstructure MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Mofstructure MCP server in PolicyLayer and add a rule for remove_guest: 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 Mofstructure. Nothing to install.
remove_guest is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the remove_guest 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 remove_guest. 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.
remove_guest is provided by the Mofstructure MCP server (lichman0405/mofstructure-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
remove_guest is one line of Mofstructure's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
