Search the graph memory for relevant facts.
AI agents call search_memory_facts 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 is a read-only operation that searches and retrieves facts from a knowledge graph stored in Neo4j. It has no side effects, does not modify data, and does not execute code or trigger external operations. The search capability poses minimal security risk as it only exposes information already stored in the system.
From the tool's definition Tool name 'search_memory_facts' and description 'Search the graph memory for relevant facts' indicate a query/retrieval operation with no modification of underlying data.
Documented attack patterns abuse exactly the kind of access search_memory_facts 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 search_memory_facts:
{
"version": "1",
"default": "deny",
"tools": {
"search_memory_facts": {}
}
}search_memory_facts is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Search the graph memory for relevant facts. 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 search_memory_facts: 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.
search_memory_facts 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 search_memory_facts 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 search_memory_facts. 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.
search_memory_facts 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.
