Get wallet address from private key with proper checksum formatting
AI agents call get_wallet_address_from_private_key to retrieve information from EDUCHAIN Agent Kit without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Although the tool handles sensitive cryptographic material (private keys), its function is strictly informational: deriving and returning the corresponding wallet address. This is a Read operation. However, severity is high because misuse in an agent context could expose private key handling, potentially leading to key leakage or compromise if the derived address is logged or shared insecurely.
From the tool's definition Tool name and description indicate it 'Get wallet address from private key' — a lookup/derivation operation that retrieves data (wallet address) from supplied input. No modification, deletion, or external action is performed.
Documented attack patterns abuse exactly the kind of access get_wallet_address_from_private_key gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and EDUCHAIN Agent Kit, and nothing reaches the server without passing your rules. This is the rule we recommend for get_wallet_address_from_private_key:
{
"version": "1",
"default": "deny",
"tools": {
"get_wallet_address_from_private_key": {}
}
}get_wallet_address_from_private_key is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get wallet address from private key with proper checksum formatting. It is categorised as a Read tool in the EDUCHAIN Agent Kit MCP Server, which means it retrieves data without modifying state.
Register the EDUCHAIN Agent Kit MCP server in PolicyLayer and add a rule for get_wallet_address_from_private_key: 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 EDUCHAIN Agent Kit. Nothing to install.
get_wallet_address_from_private_key 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_wallet_address_from_private_key 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_wallet_address_from_private_key. 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_wallet_address_from_private_key is provided by the EDUCHAIN Agent Kit MCP server (sailfish-finance/educhain-ai-agent-kit). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from EDUCHAIN Agent Kit, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
