AI agents call context_now to retrieve information from Novyx without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves existing data (the current memory context) without modifying, executing external operations, deleting, or affecting financial systems. It is a safe read operation with minimal risk even if misused, as it only exposes information already accessible to the agent within its current session.
From the tool's definition Tool name 'context_now' and description 'Get a snapshot of your current memory context' indicate a retrieval operation with no side effects. The verb 'Get' and 'snapshot' are characteristic of read-only operations.
Documented attack patterns abuse exactly the kind of access context_now gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Novyx, and nothing reaches the server without passing your rules. This is the rule we recommend for context_now:
{
"version": "1",
"default": "deny",
"tools": {
"context_now": {}
}
}context_now is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get a snapshot of your current memory context. It is categorised as a Read tool in the Novyx MCP Server, which means it retrieves data without modifying state.
Register the Novyx MCP server in PolicyLayer and add a rule for context_now: 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 Novyx. Nothing to install.
context_now is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the context_now 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 context_now. 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.
context_now is provided by the Novyx MCP server (novyxlabs/novyx-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
