Get an entity edge from the graph memory by its UUID.
AI agents call get_entity_edge to retrieve information from Graphiti MCP Demo without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves a single entity edge from a Neo4j-backed knowledge graph using a UUID lookup. It performs a query operation that reads data without modifying, deleting, or executing arbitrary logic. No data is created, modified, or destroyed.
From the tool's definition Tool name 'get_entity_edge' and description 'Get an entity edge from the graph memory by its UUID' indicate a retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access get_entity_edge gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Graphiti MCP Demo, and nothing reaches the server without passing your rules. This is the rule we recommend for get_entity_edge:
{
"version": "1",
"default": "deny",
"tools": {
"get_entity_edge": {}
}
}get_entity_edge is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get an entity edge from the graph memory by its UUID. It is categorised as a Read tool in the Graphiti MCP Demo MCP Server, which means it retrieves data without modifying state.
Register the Graphiti MCP Demo MCP server in PolicyLayer and add a rule for get_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 Demo. Nothing to install.
get_entity_edge is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_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 get_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.
get_entity_edge is provided by the Graphiti MCP Demo MCP server (kartikk-26/graphiti-mcp-demo). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Graphiti MCP Demo, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
