get_weak_functions
AI agents call get_weak_functions to retrieve information from EMBA-MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
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.
From the tool's definition Tool name 'get_weak_functions' suggests retrieval of function information; consistent with sibling tools (get_binary_protection_mechanisms, get_bootloader_info, get_credentials_and_secrets, get_filesystem_overview) which all retrieve/query firmware analysis…
Documented attack patterns abuse exactly the kind of access get_weak_functions gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and EMBA-MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for get_weak_functions:
{
"version": "1",
"default": "deny",
"tools": {
"get_weak_functions": {}
}
}get_weak_functions is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

get_weak_functions. It is categorised as a Read tool in the EMBA-MCP MCP Server, which means it retrieves data without modifying state.
Register the EMBA- MCP server in PolicyLayer and add a rule for get_weak_functions: 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 EMBA-MCP. Nothing to install.
get_weak_functions 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_weak_functions 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_weak_functions. 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_weak_functions is provided by the EMBA- MCP server (0xbuz3r/emba-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from EMBA-MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
