Part of the Knowledge Graph Server MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents may call delete_edge to permanently remove or destroy resources in Knowledge Graph Server. Without a policy, an autonomous agent could delete critical data in a loop with no way to undo the damage. Intercept blocks destructive tools by default and requires explicit human approval before enabling them.
Without a policy, an AI agent could call delete_edge in a loop, permanently destroying resources in Knowledge Graph Server. There is no undo for destructive operations. Intercept blocks this tool by default and only allows it when a human explicitly approves the action.
Destructive tools permanently remove data. Block by default. Only enable with explicit approval workflows.

delete_edge is one of the critical-risk operations in Knowledge Graph Server. For the full severity-focused view — only the critical-risk tools with their recommended policies — see the breakdown for this server, or browse all critical-risk tools across every MCP server.
Delete edges from the knowledge graph. This tool must be used in conjunction with list_graphs and get_node_details tools, and the operation cannot be undone. Use cases: 1. Delete incorrectly created relationships 2. Update relationship structure between nodes 3. Clean up redundant relationships when restructuring the graph Usage recommendations: 1. First call list_graphs to get target graph information 2. Use get_node_details to get edge details 3. Confirm deletion won't break important relationship structures 4. Set confirmDelete to true to confirm deletion Important notes: - Deleting edges won't affect related nodes - Need to call get_node_details again to view updated relationships Return data: - data: Deletion result * id: Deleted edge ID * deletedAt: Deletion time. It is categorised as a Destructive tool in the Knowledge Graph Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Add a rule in your Intercept YAML policy under the tools section for delete_edge. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Knowledge Graph Server MCP server.
delete_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 delete_edge rule in your Intercept 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 Intercept policy for delete_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.
delete_edge is provided by the Knowledge Graph Server MCP server (aiuluna/knowledge-graph-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Open source. One binary. Zero dependencies.
