Remove a block from an opened project
AI agents call remove_block to permanently remove resources in Pl — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Removing a block from a project is a destructive action that cannot be undone; it permanently deletes a component/block from the project structure. The sibling tool 'delete_project' confirms this server deals with irreversible deletions, and 'remove_block' follows the same pattern at the block level.
From the tool's definition 'Remove a block from an opened project' — 'remove' indicates irreversible deletion of a block from the project
Attacks that exploit this kind of access
Remove a block from an opened project. It is categorised as a Destructive tool in the Pl MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Pl MCP server in PolicyLayer and add a rule for remove_block: 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 Pl. Nothing to install.
remove_block 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_block 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_block. 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_block is provided by the Pl MCP server (@milaboratories/pl-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
