Get an entity edge from the graph memory by its UUID.
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 a specific entity relationship (edge) from the knowledge graph using its unique identifier. It performs no modification, deletion, or side effects—it only queries and returns information. This is a straightforward read operation with minimal risk even in adversarial scenarios, as it cannot alter state or trigger external actions.
From the tool's definition Tool name 'get_entity_edge' combined with description 'Get an entity edge from the graph memory by its UUID' indicates a retrieval operation.
Attacks that exploit this kind of access
Get an entity edge from the graph memory by its UUID. 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 (tesfandiari1/graphiti-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
