mcp-near-wallet-manager

MCP server for NEAR wallet operations with three production tools:

  • create_wallet
  • check_balance
  • sign_transaction

Designed for agent workflows where wallets must be provisioned, checked, and used for deterministic signing.

What This Delivers (Job Mapping)

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

Install

npm install -g mcp-near-wallet-manager
