Get the most recent episodes for a specific group. Args: group_id: ID of the group to retrieve episodes from. If not provided, uses the default group_id. last_n: Number of most recent episodes to retrieve (default: 10)
AI agents call get_episodes 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/queries existing episodes from the Neo4j knowledge graph without side effects. It fits the Read category as a straightforward data fetch operation. Severity is low because retrieval of historical episode data presents minimal risk even if misused by an agent.
From the tool's definition Tool name 'get_episodes' and description 'Get the most recent episodes for a specific group' indicate data retrieval with parameters 'group_id' and 'last_n' for filtering. No modification, deletion, or execution is described.
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 Server, 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 episodes for a specific group. Args: group_id: ID of the group to retrieve episodes from. If not provided, uses the default group_id. last_n: Number of most recent episodes to retrieve (default: 10). 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_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 Server. 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 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.
