Unlink resource associations from nodes. This tool must be used in conjunction with list_graphs and get_node_details tools. Use cases: 1. Adjust resource associations 2. Remove incorrect resource associations 3. Reorganize node resource structure Usage recommendations: 1. First call list_graphs ...
Part of the Knowledge Graph Server MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents may call unlink_resource 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 unlink_resource 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.

unlink_resource 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.
Unlink resource associations from nodes. This tool must be used in conjunction with list_graphs and get_node_details tools. Use cases: 1. Adjust resource associations 2. Remove incorrect resource associations 3. Reorganize node resource structure Usage recommendations: 1. First call list_graphs to get target graph information 2. Use get_node_details to view node's resource associations 3. Confirm unlinking won't affect other functionality 4. Record changes for potential re-association Important notes: - Only removes association, does not delete resource - Resource can still be used by other nodes - Association can be re-established at any time Return data: - data: Operation result * resourceId: Resource ID * nodeId: Node ID * unlinkedAt: Time when association was removed. 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 unlink_resource. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Knowledge Graph Server MCP server.
unlink_resource 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 unlink_resource 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 unlink_resource. 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.
unlink_resource 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.
