WHAT IT DOES

What get_weak_functions does on EMBA-MCP

AI agents call get_weak_functions 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_functions is rated Low

The tool appears to be a read-only query function that retrieves information about weak functions identified during firmware analysis. It follows the naming pattern of other read-category tools on the EMBA-MCP server that expose structured findings.

RECOMMENDED RULE

The rule that runs get_weak_functions safely

PolicyLayer is an MCP gateway: it sits between your AI agents and EMBA-MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For get_weak_functions, this is the rule to start with:

get_weak_functions Allowed

get_weak_functions is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect EMBA-MCP, apply this rule, and every get_weak_functions call is checked against it from then on.
