Build MCP Server: NEAR Wallet (Read-Only) for Claude

Overview

Create a read-only MCP server for NEAR wallet operations - checking balances, viewing transactions, and exploring accounts without any write capabilities.

Why This Matters

Many users want Claude to help them understand their NEAR activity without the risk of accidental transactions. Read-only mode provides safety.

Technical Requirements

Read-Only Tools

// Tools to implement (NO write operations):

// 1. get_balance - Check any account balance
// 2. get_transactions - View transaction history
// 3. get_access_keys - List account access keys
// 4. get_staking_info - View staking/delegation status
// 5. explain_transaction - Decode and explain any tx

Safety Features

• No private key handling
• No transaction signing
• Clear "read-only" indicators in responses
• Works with any public account

Deliverables

1. Read-only MCP server - Published to npm
2. Zero transaction risk - By design
3. Documentation - Clear scope explanation
4. Listed in MCP Registry

Budget: 8 NEAR

Simpler scope than full wallet = lower budget, faster delivery.
