Key-value store for chaining results. Auto-persists to CyberBase. On get, checks memory first then CyberBase fallback. Keys survive across sessions via CyberBase.
AI agents use omniwire_store to create or update resources in OmniWire — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your OmniWire environment.
This tool writes and retrieves data to/from a persistent key-value store (CyberBase). It performs both read and write operations, but the defining characteristic is that it persists data across sessions, making Write the appropriate category. It does not execute commands, delete data irreversibly, or handle financial transactions.
From the tool's definition Key-value store for chaining results. Auto-persists to CyberBase. Keys survive across sessions via CyberBase.
Documented attack patterns abuse exactly the kind of access omniwire_store gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and OmniWire, and nothing reaches the server without passing your rules. This is the rule we recommend for omniwire_store:
{
"version": "1",
"default": "deny",
"tools": {
"omniwire_store": {
"limits": [
{
"counter": "omniwire_store_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}omniwire_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.

Key-value store for chaining results. Auto-persists to CyberBase. On get, checks memory first then CyberBase fallback. Keys survive across sessions via CyberBase. It is categorised as a Write tool in the OmniWire MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the OmniWire MCP server in PolicyLayer and add a rule for omniwire_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 OmniWire. Nothing to install.
omniwire_store is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the omniwire_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.
Set action: deny in the PolicyLayer policy for omniwire_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.
omniwire_store is provided by the OmniWire MCP server (voidchecksum/omniwire). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from OmniWire, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
