Harena Brief

Security checks for vulnerabilities and agentic risk

Overview

Harena Brief is a narrow hosted MCP tool for market/news briefs, with the main risk being that user-entered tickers or event keywords are sent to a remote service.

Install only if you are comfortable sending ticker symbols and event keywords to the hosted MCP provider. Avoid entering private portfolio details, personal identifiers, non-public company information, or sensitive investment plans, and independently verify financial conclusions before acting.
