Scan a symbol list for a TA-Lib indicator meeting a numeric threshold such as RSI >= 60.
AI agents call scan_indicator_threshold to retrieve information from Nubra MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs technical analysis screening by querying TA-Lib indicator values against thresholds. It returns matching symbols but does not create, modify, delete, or execute trades. No side effects or irreversible actions occur. The operation is purely informational retrieval, fitting the Read category with low severity due to minimal blast radius if misused by an AI agent.
From the tool's definition Tool scans a symbol list and retrieves indicator data meeting a threshold (RSI >= 60). The description uses 'scan' and 'meeting', indicating a query-based retrieval operation with no modification, deletion, execution of external commands, or financial…
Attacks that exploit this kind of access
Scan a symbol list for a TA-Lib indicator meeting a numeric threshold such as RSI >= 60. It is categorised as a Read tool in the Nubra MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Nubra MCP Server MCP server in PolicyLayer and add a rule for scan_indicator_threshold: 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 Nubra MCP Server. Nothing to install.
scan_indicator_threshold 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 scan_indicator_threshold 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 scan_indicator_threshold. 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.
scan_indicator_threshold is provided by the Nubra MCP Server MCP server (socials-zanskar/nubra-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
