Get an entity edge from the Graphiti knowledge graph by its UUID. Args: uuid: UUID of the entity edge to retrieve
AI agents call get_entity_edge to retrieve information from Graphiti MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves an existing entity edge from a Neo4j knowledge graph using its UUID as a lookup parameter. No data is created, modified, or deleted. The operation is purely informational and produces no side effects. This is a straightforward Read-category operation with low severity since retrieval of graph data poses minimal risk of harm even if misused by an AI agent.
From the tool's definition Tool name 'get_entity_edge' and description 'Get an entity edge from the Graphiti knowledge graph by its UUID' indicate a retrieval operation with no side effects. The verb 'Get' and the action of retrieving data by UUID are characteristic of Read operations.
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 Server, 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 Graphiti knowledge graph by its UUID. Args: uuid: UUID of the entity edge to retrieve. It is categorised as a Read tool in the Graphiti MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Graphiti MCP Server 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 Server. 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 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.
