Clear all data from the graph for specified group IDs.
AI agents call clear_graph 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 performs bulk data deletion that cannot be undone. The verb 'clear' combined with 'all data' indicates comprehensive, permanent removal rather than reversible modification. While the blast radius is limited to specified group IDs (not system-wide), the irreversible nature and volume of data affected make this Destructive rather than Write.
From the tool's definition Tool name 'clear_graph' and description 'Clear all data from the graph for specified group IDs' explicitly indicates irreversible deletion of all data within a graph scope.

Clear all data from the graph for specified group IDs. 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 clear_graph: 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.
clear_graph 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 clear_graph 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 clear_graph. 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.
clear_graph is provided by the Graphiti MCP Server MCP server (tesfandiari1/graphiti-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
