Lets AI agents check whether an EVM wallet address carries an EIP-7702 delegation across eight chains (Ethereum, Base, BNB Chain, Arbitrum, OP, Polygon, Gnosis, Unichain) and learn how to obtain a deeper paid report with delegate bytecode heuristics and risk levels. Read-only, never touching private keys or seed phrases.

Teaches AI coding agents how to reason correctly about MetaMask Embedded Wallets / Web3Auth architecture, SDK choice, key derivation, auth flows, and common integration pitfalls.

Enables an AI agent to check whether contracts are covered by ERC-7730 descriptors, preview how transactions and typed-data signatures would appear to a person, and simulate execution outcomes before signing, without holding keys or submitting transactions.

Read-only access to the live NOVAI blockchain (an AI-native L1) over public JSON-RPC. Query blocks, transactions, AI entities, on-chain signals, oracle anchors, and memory objects. No keys, no write paths.

Includes onboarding tools for headless agents and read-only versus write access controlled by an API key and a write-enabled flag.

MCP server for Bags on Solana. Reads token analytics, creator-fee data and trade quotes; executes swaps and fee claims only behind a token gate, a hard SOL spend cap, and a single-use confirmation token bound to the exact arguments. The first call to a write tool signs nothing — it returns a preview. 14 tools, 337 tests at 100% coverage enforced in CI, mainnet-only writes, npm provenance.
