Overview

AI-generated overview

Lets an assistant create NEAR wallets, check account balances, and sign NEAR transactions locally.

What you can do
Exposes three tools for NEAR blockchain wallet work: create_wallet generates an ED25519 keypair or imports an existing private key and returns the public key and implicit account id; check_balance fetches total, locked, and available balances plus key count over NEAR JSON-RPC; sign_transaction signs transfer or function_call payloads and returns the transaction hash, signature, and base64 signed blob.
When to use it
Use it in agent workflows that need to provision a NEAR wallet, inspect an account's balance, or produce signed NEAR transactions deterministically from a local process.
Requirements
Runs as a local stdio process installed from the npm package mcp-near-wallet-manager (Node.js required). Network access to NEAR JSON-RPC is needed for balance checks and signing. No environment variables, headers, or accounts are declared; sign_transaction takes the signer private key as a tool input.
Before you install
create_wallet can return a private key, and sign_transaction accepts signer_private_key as an input, so secrets pass through the assistant and its logs; the README warns to treat returned keys as sensitive, never store private keys in plaintext logs, and use dedicated signer accounts with minimal permissions. Signing produces valid transactions that can move funds, so review actions and deposits before use.

Installation

In SourceWeft

  1. Open Near Wallet Manager in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

README

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

bash
npm install -g mcp-near-wallet-manager
