Summary
Private tokens on COTI, handled end to end.
The private ERC20 and ERC721 sets are the reason to reach for this over a generic EVM server: minting, transferring and reading a balance all go through COTI's encryption, and the AES key tools that make those readable sit in the same place.
What it is
An interface to the COTI blockchain built around its MPC-based private token support. The tools cover accounts and keys, private ERC20 and ERC721 operations, contract calls and native COTI transfers.
What you get
- Account handling: create an account, generate an AES key, encrypt and decrypt values, sign and verify messages, read or switch the current network (create_account, generate_aes_key, encrypt_value, decrypt_value, sign_message, verify_signature, get_current_network, switch_network)
- Private ERC20: deploy a contract, mint, transfer, approve a spender, and read balance, allowance, decimals and total supply (deploy_private_erc20_contract, mint_private_erc20_token, transfer_private_erc20, approve_erc20_spender, get_private_erc20_balance, get_private_erc20_allowance, get_private_erc20_decimals, get_private_erc20_total_supply)
- Private ERC721: deploy a collection, mint, transfer, approve one token or an operator for all, and read owner, balance, token URI and total supply (deploy_private_erc721_contract, mint_private_erc721_token, transfer_private_erc721, approve_private_erc721, set_private_erc721_approval_for_all, get_private_erc721_token_owner, get_private_erc721_balance, get_private_erc721_token_uri, get_private_erc721_total_supply, get_private_erc721_approved, get_private_erc721_is_approved_for_all)
- Transactions: call a contract function, read logs and status, decode event data (call_contract_function, get_transaction_logs, get_transaction_status, decode_event_data)
- Native COTI: read a balance and transfer (get_native_balance, transfer_native)
Requirements
Node.js v18 or higher and a COTI AES key. Private balances are encrypted on-chain, so without the key the read tools have nothing to return in the clear.
Setup effort
One command plus a key — npx -y @smithery/cli install @davibauer/coti-mcp --client claude, then supply credentials
