Overview

Description from the maker (original English)

Nano cryptocurrency operations wallet, balance, transactions via MCP

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs in the cloud
  • Transport: Streamable HTTP
  • Category: Crypto & blockchain

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 2 passed Fail
  • Runs on the maker’s server: what you ask it goes through their server.
  • The registry lists no key to fill in.

What it can do

The server did not answer when we last checked, so we could not read its tools.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.

Common questions

Is NANO MCP safe?

It passed 1 of 2 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.5.1) reached the registry 7 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

⚡ Fastest Integration Path (AI Agents: START HERE)

Complete workflow in 5-6 calls, 30-60 seconds:

// STEP 1: Setup test wallets (1 call, < 1s)

POST https://nano-mcp.replit.app {"jsonrpc":"2.0","method":"setupTestWallets","params":{},"id":1} → Returns: wallet addresses + private keys

// STEP 2: Human funds both addresses (30-60s wait) // → Send 0.1+ NANO to each address

// STEP 3: Check BOTH wallets in parallel (2 calls, 4-6s) POST https://nano-mcp.replit.app {"jsonrpc":"2.0","method":"getAccountStatus","params":{"address":"wallet1_address"},"id":1} {"jsonrpc":"2.0","method":"getAccountStatus","params":{"address":"wallet2_address"},"id":2} → Returns: balance, pending blocks, needsAction

// STEP 4: Follow needsAction automatically (2 calls, 16-24s) POST https://nano-mcp.replit.app {"jsonrpc":"2.0","method":"initializeAccount","params":{"address":"wallet1","privateKey":"key1"},"id":1} {"jsonrpc":"2.0","method":"initializeAccount","params":{"address":"wallet2","privateKey":"key2"},"id":2} → Returns: initialized confirmation

// STEP 5: Send transaction (1 call, 10-15s) POST https://nano-mcp.replit.app {"jsonrpc":"2.0","method":"sendTransaction","params":{ "fromAddress":"wallet1", "toAddress":"wallet2", "amountRaw":"50000000000000000000000000", "privateKey":"key1" },"id":1} → Returns: transaction hash

// DONE! ✅ Total: 6 calls, ~60 seconds (including human wait)

⚠️ CRITICAL: Work Generation Performance

Proof-of-Work (PoW) generation time varies significantly by system:

  • Fast systems: 10-15 seconds
  • Slower systems: 30-60 seconds
  • ALWAYS set 60-second timeout minimum for transaction functions (initializeAccount, sendTransaction, receiveAllPending)

If experiencing timeouts:

  1. Increase timeout to 90-120 seconds
  2. Check system CPU availability
  3. Don't retry immediately - work might still be processing
  4. Check account status after timeout - transaction may have completed
❌ DON'T Do These (Time Wasters)

1. Don't call `getBalance` then `getAccountStatus`

// ❌ INEFFICIENT: 2 calls, 4-6s

await call('getBalance', {address}) // Returns: balance, pending await call('getAccountStatus', {address}) // Returns: balance, pending + more

// ✅ EFFICIENT: 1 call, 2-3s await call('getAccountStatus', {address}) // Returns: everything you need

2. Don't call `checkTestWalletsFunding` repeatedly

// ❌ INEFFICIENT: Shows 0 until manually updated

await call('checkTestWalletsFunding') // Returns: bothFunded: false await call('checkTestWalletsFunding') // Still false (not auto-updating)

// ✅ EFFICIENT: Check blockchain directly await call('getAccountStatus', {address}) // Shows pending blocks immediately

3. Don't set short timeouts on transactions

// ❌ FAILS: Work generation takes 10-15 seconds

await call('sendTransaction', {...}, {timeout: 5000}) // Times out!

// ✅ WORKS: Proper timeout await call('sendTransaction', {...}, {timeout: 30000}) // Completes successfully

4. Don't test functions sequentially when independent

// ❌ SLOW: 6 seconds total

await call('getAccountStatus', {address: wallet1}) // 3s await call('getAccountStatus', {address: wallet2}) // 3s

// ✅ FAST: 3 seconds total await Promise.all([ call('getAccountStatus', {address: wallet1}), call('getAccountStatus', {address: wallet2}) ]) // Both in 3s

💡 Pro Tips for AI Agents
  1. Use `getAccountStatus` for everything - It replaces getBalance, getAccountInfo, getPendingBlocks
  2. Follow `needsAction` array - Auto-recovery without trial-and-error
  3. Batch independent calls - Use Promise.all or batch requests
  4. Set generous timeouts - 60s minimum for transactions (system performance varies)
  5. Save setupTestWallets response - Don't call getTestWallets unless retrieving
  6. Don't retry on timeout - Check account status first, transaction may have completed
  7. Expect work generation variability - 10-60s depending on system load
