从列表变量删除项
AI agents call remove_from_list_variable to permanently remove resources in Code Analysis MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Removing an item from a list variable is a destructive operation in that the item is deleted/removed, likely irreversibly unless there is an undo mechanism (none described). Sibling tools include 'delete_list_variable' and 'delete_plan', suggesting this server treats removals as permanent. Severity is medium since it affects stored variable data rather than source files or financial records.
From the tool's definition '从列表变量删除项' translates to 'delete items from list variable' — the operation removes data from a stored list variable
Attacks that exploit this kind of access
从列表变量删除项. It is categorised as a Destructive tool in the Code Analysis MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Code Analysis MCP Server MCP server in PolicyLayer and add a rule for remove_from_list_variable: 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 Code Analysis MCP Server. Nothing to install.
remove_from_list_variable 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_from_list_variable 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_from_list_variable. 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_from_list_variable is provided by the Code Analysis MCP Server MCP server (zeocax/code-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
