WHAT IT DOES

What neuroverse_store does on Neuroverse

AI agents use neuroverse_store to create or update resources in Neuroverse — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Neuroverse environment.

WHY IT NEEDS A POLICY

Why neuroverse_store needs a policy

This tool writes/creates a memory record in the NeuroVerse system. It is a Write operation as it creates new data (memory records) in a persistent store. Misuse could lead to injection of false memories or context poisoning for autonomous AI agents, which raises the severity to medium. The operation appears reversible (records can presumably be deleted or overwritten), so it doesn't qualify as Destructive.

Verdict

neuroverse_store Rate-limited

neuroverse_store stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about neuroverse_store

What does the neuroverse_store tool do? +

Store a memory record in NeuroVerse. It is categorised as a Write tool in the Neuroverse MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on neuroverse_store? +

Register the Neuroverse MCP server in PolicyLayer and add a rule for neuroverse_store: 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 Neuroverse. Nothing to install.

What risk level is neuroverse_store? +

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

Can I rate-limit neuroverse_store? +

Yes. Add a rate_limit block to the neuroverse_store 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.

How do I block neuroverse_store completely? +

Set action: deny in the PolicyLayer policy for neuroverse_store. 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 neuroverse_store? +

neuroverse_store is provided by the Neuroverse MCP server (joshua400/neuroverse). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
