WHAT IT DOES

What get_weak_crypto_and_keys does on EMBA-MCP

AI agents call get_weak_crypto_and_keys to retrieve information from EMBA-MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why get_weak_crypto_and_keys is rated Low

The 'get_' prefix and position among purely informational query tools indicates a Read operation that queries existing firmware analysis results. While the sensitive nature of cryptographic weakness and key data elevates severity (medium rather than low) due to potential for misuse if keys are exposed, the tool itself performs no destructive, write, execute, or financial operations—it only retrieves data that has…

From the tool's definition Tool name 'get_weak_crypto_and_keys' indicates retrieval ('get') of cryptographic weakness information and key data from firmware analysis results.
