What session_delete does on Ruflo
AI agents call session_delete to permanently remove resources in Ruflo, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Why session_delete is rated Critical
The tool permanently deletes saved session data including agent definitions, topology configuration, memory stores, and historical state. This is a destructive action that cannot be undone and eliminates persistent state across the swarm system. An AI agent misusing this could irreversibly destroy critical system configuration and operational history, making it Destructive rather than merely Write.
From the tool's definition Tool name 'session_delete' combined with description stating 'Delete a saved session' with explicit mention of deleting 'durable cross-session state — restoring agent definitions, swarm topology, memory store, breaker history.' This is an irreversible…
Attacks that exploit this kind of access
The rule that runs session_delete safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Ruflo, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For session_delete, this is the rule to start with:
session_delete is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
The button opens the PolicyLayer dashboard: create your workspace, connect Ruflo, apply this rule, and every session_delete call is checked against it from then on.
Questions about session_delete
Delete a saved session Use when native conversation memory is wrong because you need durable cross-session state — restoring agent definitions, swarm topology, memory store, breaker history. For in-session continuation only, no tool needed. Pair with session_save before exiting and session_restore on resume. It is categorised as a Destructive tool in the Ruflo MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Ruflo MCP server in PolicyLayer and add a rule for session_delete: 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 Ruflo. Nothing to install.
session_delete is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the session_delete 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 session_delete. 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.
session_delete is provided by the Ruflo MCP server (ruvnet/ruflo). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
