Risky Repositories

These tools failed our security audit. They are listed here to call them out, not to recommend them. Review source code and permissions carefully before installing.

Repository	Risk Level	Why
EVM Wallet Skill	Dangerous	Generates and stores a private key at `~/.evm-wallet.json`, giving the AI agent full hot wallet control. Mainnet-by-default across 6 chains.
MCP Crypto Wallet EVM	Dangerous	Exposes private keys and mnemonics to LLM context via `wallet_get_private_key`. Full wallet lifecycle management.
Blockchain MCP	Dangerous	Private key passed as plaintext tool parameter through LLM context. Sends transactions on 7 mainnets.
EVM MCP Server	Dangerous	Private key/mnemonic via env vars across 60+ mainnet chains. HTTP mode binds to `0.0.0.0` (network-exposed).
Foundry MCP Server	Dangerous	Executes arbitrary Forge scripts and sends mainnet transactions with configured private key. No testnet enforcement.
EVM Agent Skills	Dangerous	Defaults to Ethereum mainnet with transaction signing and broadcasting via `cast`. Very broad RPC permissions.
Crypto Skills	Unsafe	Token Minter deploys contracts requiring signing. Write operations via EVM Swiss Knife. No testnet safeguards.
