Summary
This server gives Claude direct access to NEAR Protocol wallet operations through three focused tools: creating ED25519 keypairs with implicit account IDs, fetching account balances via NEAR's JSON-RPC, and signing transaction payloads for transfers or function calls. It's built for agent workflows that need to provision wallets on the fly, check balances, and execute deterministic transaction signing without manual intervention. The sign_transaction tool handles the full signing flow and returns both the signature and base64 encoded transaction blob ready for broadcast. Useful when you're building agents that need to manage NEAR accounts programmatically or execute on-chain actions as part of automated workflows on testnet or mainnet.
Keep your Mac awake while Claude Code and 40+ AI agents run. Sleeps when they're idle.

MCP server for NEAR wallet operations with three production tools:
create_walletcheck_balancesign_transaction
Designed for agent workflows where wallets must be provisioned, checked, and used for deterministic signing.

- Wallet creation
- Generates ED25519 keypair or imports existing private key
- Returns public key + implicit account id
- Balance checking
- Fetches account balance over NEAR JSON-RPC
- Returns total/locked/available balances and key count
- Transaction signing
- Signs NEAR transaction payloads with transfer/function_call actions
- Returns transaction hash, signature, and base64 signed transaction blob
Install
