THE RISK

Critical Risk

Why ragflow_reset_session needs a policy

Resetting/clearing a chat session is an irreversible destructive action — the session history and context are wiped. While not catastrophic in terms of data loss (no documents or datasets are deleted), the session state cannot be recovered after clearing, making it Destructive rather than Write. Severity is medium because only session/conversation data is lost, not underlying knowledge base content.

From the tool's definition Reset/clear the chat session for a specific dataset

POLICY

How to control ragflow_reset_session

PolicyLayer is an MCP gateway — it sits between your AI agents and RAGFlow Claude MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for ragflow_reset_session:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "ragflow_reset_session"
  ]
}

ragflow_reset_session disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Create a free account and register RAGFlow Claude MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
