AI agents call mem0_get_graph_relations to retrieve information from Mem0 MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'get_' prefix and 'graph_relations' suggest this retrieves relationship data from a knowledge graph—a read-only query operation. Sibling tools include deletion (mem0_delete_memory) and addition operations (mem0_add_*), confirming this server supports writes and deletes, but this specific tool appears designed for retrieval.
From the tool's definition Tool name 'mem0_get_graph_relations' indicates a retrieval operation ('get') from a graph structure. No description provided, but naming convention and context within a memory management system suggest querying relationships without modification.
Documented attack patterns abuse exactly the kind of access mem0_get_graph_relations gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Mem0 MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for mem0_get_graph_relations:
{
"version": "1",
"default": "deny",
"tools": {
"mem0_get_graph_relations": {}
}
}mem0_get_graph_relations is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

mem0_get_graph_relations. It is categorised as a Read tool in the Mem0 MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Mem0 MCP Server MCP server in PolicyLayer and add a rule for mem0_get_graph_relations: 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 Mem0 MCP Server. Nothing to install.
mem0_get_graph_relations 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 mem0_get_graph_relations 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 mem0_get_graph_relations. 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.
mem0_get_graph_relations is provided by the Mem0 MCP Server MCP server (ryaker/mcp-mem0-general). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Mem0 MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
