Get the most recent memory episodes for a specific group.
AI agents call get_episodes 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 queries and retrieves historical memory episodes for a group. It performs a read-only operation that fetches existing data without creating, modifying, deleting, or executing any operations. The verb 'Get' and the retrieval-only nature of the function clearly indicate a Read category tool. Severity is low because retrieving memory metadata poses minimal risk of harm even if misused by an AI agent.
From the tool's definition Tool description explicitly states 'Get the most recent memory episodes' - a retrieval operation with no modification or side effects.
Documented attack patterns abuse exactly the kind of access get_episodes 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_episodes:
{
"version": "1",
"default": "deny",
"tools": {
"get_episodes": {}
}
}get_episodes is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get the most recent memory episodes for a specific group. 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_episodes: 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_episodes 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_episodes 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_episodes. 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_episodes 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.
