Remove an edge from the diagram.
AI agents call remove_edge to permanently remove resources in Flowchart MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Removing an edge deletes it from the diagram with no indication of an undo mechanism. This is a destructive operation as the edge data is lost. Severity is medium since it affects only a single connection between nodes rather than entire diagrams or nodes themselves.
From the tool's definition 'Remove an edge from the diagram' — removal is an irreversible deletion of a diagram element
Attacks that exploit this kind of access
Remove an edge from the diagram. It is categorised as a Destructive tool in the Flowchart MCP MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Flowchart MCP server in PolicyLayer and add a rule for remove_edge: 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 Flowchart MCP. Nothing to install.
remove_edge 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_edge 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_edge. 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_edge is provided by the Flowchart MCP server (zafer-liu/flowchart_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
remove_edge is one line of Flowchart's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
