Delete all data (episodes, nodes, and entity edges) associated with a group_id. This is an atomic operation that completely removes a group from the system in a single call. Returns counts of deleted entities.
AI agents call delete_everything_by_group_id to permanently remove resources in Graphiti Knowledge Graph MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently and irreversibly deletes entire groups of data in a single atomic operation. There is no undo mechanism mentioned, and the deletion encompasses all associated records (episodes, nodes, edges). The blast radius is maximum—an AI agent with access to this tool could permanently destroy all knowledge graph data for a group, causing complete data loss.
From the tool's definition Tool description explicitly states 'Delete all data (episodes, nodes, and entity edges) associated with a group_id' and 'completely removes a group from the system in a single call.' The verb 'delete' combined with 'all data' and 'completely removes'…
Documented attack patterns abuse exactly the kind of access delete_everything_by_group_id gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Graphiti Knowledge Graph MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for delete_everything_by_group_id:
{
"version": "1",
"default": "deny",
"hide": [
"delete_everything_by_group_id"
]
}delete_everything_by_group_id disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Delete all data (episodes, nodes, and entity edges) associated with a group_id. This is an atomic operation that completely removes a group from the system in a single call. Returns counts of deleted entities. It is categorised as a Destructive tool in the Graphiti Knowledge Graph MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Graphiti Knowledge Graph MCP Server MCP server in PolicyLayer and add a rule for delete_everything_by_group_id: 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 Knowledge Graph MCP Server. Nothing to install.
delete_everything_by_group_id 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_everything_by_group_id 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_everything_by_group_id. 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_everything_by_group_id is provided by the Graphiti Knowledge Graph MCP Server MCP server (michabbb/graphiti-mcp-but-working). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Graphiti Knowledge Graph MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
