Alchemy MCP — Ethereum + L2 enhanced RPC (NFT, token, txn enrichment endpoints). Free key 300M compute units/mo.

Auth

• Platform: PLATFORM_ALCHEMY_KEY. BYO: ?_apiKey=….
• Chain selector: pass chain to most tools (eth-mainnet (default) | eth-sepolia | polygon-mainnet | arb-mainnet | opt-mainnet | base-mainnet).

Tools (Core RPC passthrough)

• eth_call(method, params, chain?) — generic JSON-RPC call

Tools (Token API)

• token_balances(address, contracts?, chain?) — ERC-20 balances
• token_metadata(contract, chain?) — ERC-20 metadata
• token_allowance(contract, owner, spender, chain?) — allowance

Tools (NFT API)

• nfts_owned(owner, contracts?, page_key?, page_size?, chain?) — NFTs owned by address
• nft_metadata(contract, tokenId, refresh_cache?, chain?) — single NFT metadata
• nfts_for_collection(contract, withMetadata?, startToken?, limit?, chain?) — NFTs in a collection
• nft_owners(contract, tokenId?, chain?) — owners of a contract / token

Tools (Transfers + Webhooks)

• asset_transfers(from?, to?, contract_addresses?, category?, fromBlock?, toBlock?, order?, withMetadata?, excludeZeroValue?, maxCount?, pageKey?, chain?) — enhanced transfer feed
