Medium Risk

hibernate

Save current session state for next awakening. Call at the END of every session to preserve what you were working on, what you learned, and next steps.

@memory-nexus/mcp Write Risk 3/5

AI agents use hibernate to create or modify resources in Memory Nexus. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.

Without a policy, an AI agent could call hibernate repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Memory Nexus.

Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

What does the hibernate tool do? +

Save current session state for next awakening. Call at the END of every session to preserve what you were working on, what you learned, and next steps.. It is categorised as a Write tool in the Memory Nexus MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on hibernate? +

Add a rule in your Intercept YAML policy under the tools section for hibernate. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Memory Nexus MCP server.

What risk level is hibernate? +

hibernate is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit hibernate? +

Yes. Add a rate_limit block to the hibernate rule in your Intercept 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.

How do I block hibernate completely? +

Set action: deny in the Intercept policy for hibernate. 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.

What MCP server provides hibernate? +

hibernate is provided by the Memory Nexus MCP server (@memory-nexus/mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
