Delete an entity edge from the Graphiti knowledge graph. Args: uuid: UUID of the entity edge to delete
AI agents call delete_entity_edge to permanently remove resources in Graphiti MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes data (relationship edges) from a Neo4j knowledge graph. Deletion is irreversible and represents a loss of structured information. While the blast radius may be limited to a single edge rather than an entire graph or entity, the destructive nature of permanent data removal places it in the Destructive category, which is more severe than Write (which covers reversible modifications).
From the tool's definition Tool name contains 'delete' and description states 'Delete an entity edge from the Graphiti knowledge graph.' The operation is irreversible — once an edge is deleted from the knowledge graph, the relationship between entities cannot be recovered without…
Documented attack patterns abuse exactly the kind of access delete_entity_edge gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Graphiti MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for delete_entity_edge:
{
"version": "1",
"default": "deny",
"hide": [
"delete_entity_edge"
]
}delete_entity_edge disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Delete an entity edge from the Graphiti knowledge graph. Args: uuid: UUID of the entity edge to delete. It is categorised as a Destructive tool in the Graphiti MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Graphiti MCP Server MCP server in PolicyLayer and add a rule for delete_entity_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 Graphiti MCP Server. Nothing to install.
delete_entity_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_entity_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 delete_entity_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_entity_edge is provided by the Graphiti MCP Server MCP server (rawr-ai/mcp-graphiti). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
