AI agents call get_now to retrieve information from OathScore 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 real-time data (exchange status, volatility indices, economic events, data health metrics) without creating, modifying, deleting, or executing anything. It is a read-only data aggregation endpoint.
From the tool's definition Tool description states 'Get current world state' and 'One call replaces 4-6 separate API calls' — purely retrieval operation with no modification, deletion, execution, or financial side effects. Collects market data and status information only.
Attacks that exploit this kind of access
Get current world state: exchange status, volatility (VIX/VVIX/SKEW/term structure), economic event countdowns, and data health. One call replaces 4-6 separate API calls. It is categorised as a Read tool in the OathScore MCP Server, which means it retrieves data without modifying state.
Register the OathScore MCP server in PolicyLayer and add a rule for get_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 OathScore. Nothing to install.
get_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 get_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 get_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.
get_now is provided by the OathScore MCP server (moxiespirit/oathscore). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
