# Algorand MCP Interaction

Interact with Algorand blockchain through the Algorand MCP server (126 tools across 16 categories, including x402 payments and Bazaar discovery).

## Key Characteristics

- **Agent wallet** — the MCP server holds mnemonics in a local SQLite DB at `~/.algorand-mcp/wallet.db` (file mode `0600`) and signs transactions on your behalf via the `wallet_*` tools. Mnemonics are never returned in tool responses. The DB file IS the secret — protect the data directory like any secret material (relevant for Docker: mount `~/.algorand-mcp` as a persistent volume).
- **Multi-network** — supports `mainnet`, `testnet`, and `localnet`

## mcporter Syntax (Critical)

When calling Algorand MCP tools via mcporter, use the correct syntax:

**Correct:**
```bash
mcporter call algorand-mcp.tool_name --args '{"param": "value", "network": "testnet"}'
```

**Also correct (flag-style):**
```bash
mcporter call algorand-mcp.tool_name param=value network=testnet
```

**Wrong — args not sent properly:**
```bash
mcporter call algorand-mcp tool_name '{"param": "value"}'  # Space instead of dot, missing --args
```

Key points:
- Use `server.tool` (dot notation), NOT `server tool` (space)
- Use `--args '{"json"}'` for JSON payloads
- Or use `param=value` / `param:value` flag syntax

## Session Start Checklist

**At EVERY session start:**

1. **Check wallet**: `wallet_get_info` with target `network` — verify an account exists and is active
2. **If no accounts**: Guide user to create one with `wallet_add_account` (sets nickname)
3. **If needs funding**: Generate ARC-26 QR with `generate_algorand_qrcode` or direct to testnet faucet: https://lora.algokit.io/testnet/fund
4. **If needs USDC funding**: Generate ARC-26 QR with `generate_algorand_qrcode` or direct to testnet faucet: https://faucet.circle.com/
5. **Confirm network**: Always confirm which network (`mainnet`, `testnet`, `localnet`) before transactions

## Network Selection

Every tool that touches the blockchain accepts a `network` parameter:

| Value | Description |
|-------|-------------|
| `testnet` | Algorand testnet — **default if omitted** (algorand-mcp 4.2.5+), safe for development |
| `mainnet` | Algorand mainnet — **real value, exercise caution**. Pass only when the user explicitly names mainnet |
| `localnet` | Local dev network (requires `ALGORAND_LOCALNET_URL` env var) |

Mainnet is never implicit. If the user does not name a network, use testnet. Switch to mainnet only on an explicit user instruction, and confirm the full action (amount, asset, sender, receiver, network) before signing.

## Pre-Transaction Validation

Before ANY transaction:

1. **MBR Check**: Account needs 0.1 ALGO base + 0.1 per asset/app opt-in
2. **Asset Opt-In**: Verify with `api_algod_get_account_asset_info` before ASA transfers
3. **Fees**: Every txn costs 0.001 ALGO (1,000 microAlgos) minimum
4. **Balance Check**: Fetch current balance with `wallet_get_info` or `api_algod_get_account_info`
5. **Order**: Fund account with ALGO first, then asset transactions

## Common Mainnet Assets

| Asset | ASA ID | Decimals |
|-------|--------|----------|
| ALGO | native | 6 |
| USDC | 31566704 | 6 |
| USDT | 312769 | 6 |
| goETH | 386192725 | 8 |
| goBTC | 386195940 | 8 |

> Always verify asset IDs on-chain — scam tokens use similar names.

## Amounts and Decimals

| Asset | Unit | 1 Whole Token = |
|-------|------|-----------------|
| ALGO | microAlgos | 1,000,000 |
| USDC (ASA 31566704) | micro-units | 1,000,000 (6 decimals) |
| Custom ASAs | base units | Depends on `decimals` field |

Always check asset's `decimals` field with `api_algod_get_asset_by_id` before computing amounts.

## Transaction Types

- **pay**: ALGO transfers → `make_payment_txn`
- **axfer**: Asset transfers, opt-in, clawback → `make_asset_transfer_txn`
- **acfg**: Asset create/configure/destroy → `make_asset_create_txn`, `make_asset_config_txn`, `make_asset_destroy_txn`
- **afrz**: Asset freeze/unfreeze → `make_asset_freeze_txn`
- **appl**: Smart contract calls → `make_app_create_txn`, `make_app_call_txn`, `make_app_update_txn`, `make_app_delete_txn`, `make_app_optin_txn`, `make_app_closeout_txn`, `make_app_clear_txn`
- **keyreg**: Consensus key registration → `make_keyreg_txn`

## Wallet Transaction Workflow (Recommended)

| Step | Tool | Purpose |
|------|------|---------|
| 1 | `wallet_get_info` | Verify active account, check balance |
| 2 | Query tools | Get blockchain data (account info, asset info, etc.) |
| 3 | `make_*_txn` | Build the transaction |
| 4 | `wallet_sign_transaction` | Sign with active wallet account |
| 5 | `send_raw_transaction` | Submit signed transaction to network |
| 6 | **Present txID** | Show transaction ID with explorer link (see below) |

### Post-Transaction: Deliver Transaction ID

**ALWAYS** present the transaction ID to the user after any successful transaction submission. Use the correct explorer link based on the network:

| Network | Explorer Link Template |
|---------|----------------------|
| `mainnet` | `https://allo.info/tx/{txId}` |
| `testnet` | `https://lora.algokit.io/testnet/transaction/{txId}` |

Example output after a testnet transaction:
> Transaction confirmed! `TXID123...`
> View on explorer: https://lora.algokit.io/testnet/transaction/TXID123...

Example output after a mainnet transaction:
> Transaction confirmed! `TXID456...`
> View on explorer: https://allo.info/tx/TXID456...

This applies to ALL transaction types: payments, asset transfers, opt-ins, app calls, atomic groups, and any other operation that yields a transaction ID.

### One-Step Asset Opt-In

For asset opt-ins, use the shortcut:
```
wallet_optin_asset { assetId: 31566704, network: "testnet" }
```

## External Key Transaction Workflow

When the user provides their own secret key (not using the wallet):

| Step | Tool | Purpose |
|------|------|---------|
| 1 | `make_*_txn` | Build the transaction |
| 2 | `sign_transaction` | Sign with provided secret key hex |
| 3 | `send_raw_transaction` | Submit signed transaction |
| 4 | **Present txID** | Show transaction ID with explorer link |

## Atomic Group Transaction Workflow

For atomic (all-or-nothing) multi-transaction groups:

| Step | Tool | Purpose |
|------|------|---------|
| 1 | `make_*_txn` (multiple) | Build each transaction |
| 2 | `assign_group_id` | Assign group ID to all transactions |
| 3 | `wallet_sign_transaction_group` | Sign all transactions in group with wallet |
| 4 | `send_raw_transaction` | Submit all signed transactions |
| 5 | **Present txIDs** | Show all transaction IDs with explorer links |

## Pagination

API responses are paginated. All API tools accept optional `itemsPerPage` (default 10) and `pageToken` parameters. Pass `pageToken` from a previous response to fetch the next page.

## x402 Payments & Bazaar Discovery — load the dedicated skill

For paid HTTP resources (HTTP 402 responses), Bazaar discovery, and any workflow involving the five x402 tools (`x402_discover_payment_requirements`, `make_http_request_with_x402`, `bazaar_list`, `bazaar_search`, `bazaar_get_resource_details`), **load the dedicated `algorand-x402-payment` skill**. It covers:

- The three payment patterns (fire-and-forget, inspect-then-pay, Bazaar-then-pay)
- Tool argument cheatsheet for all five x402/Bazaar tools
- Mainnet-confirmation discipline and `maxAmountPerRequest` as a budget cap
- Common pitfalls (the `paymentRequirements[N] must be an OBJECT` schema failure, etc.)
- Wallet prerequisites (USDC opt-in, balance)
- Protocol-level reference (PaymentRequired V2 schema, fee-payer abstraction, CAIP-2 mapping, V1 vs V2 differences)

**Trigger to load**: any time you encounter an HTTP 402 response, the user mentions x402 / paid APIs / paid resources / Bazaar / "find me a paid X", or you need to call any of the five tools listed above.

## Alpha Arcade Prediction Markets

Trade on-chain prediction markets (YES/NO outcomes) denominated in USDC via the Alpha Arcade integration (14 tools).

| Step | Tool | Purpose |
|------|------|---------|
| 1 | `wallet_get_info` | Verify active account, check ALGO + USDC balance |
| 2 | `alpha_get_live_markets` | Browse available markets |
| 3 | `alpha_get_orderbook` | Check liquidity and prices for a market |
| 4 | `alpha_create_market_order` or `alpha_create_limit_order` | Place an order |
| 5 | `alpha_get_positions` / `alpha_get_open_orders` | Check portfolio |

All prices and quantities use **microunits** (1,000,000 = $1.00 or 1 share). Orders require both ALGO (~0.957 per escrow) and USDC collateral.

> For detailed Alpha Arcade workflows (orderbook mechanics, multi-choice markets, split/merge shares, claiming, collateral model), load the `alpha-arcade-interaction` skill.

## QR Code Display (ARC-26 URI)

`generate_algorand_qrcode` generates an Algorand payment URI and QR code per ARC-26 specification via QRClaw service.

**Parameters:**
| Parameter | Required | Description |
|-----------|----------|-------------|
| `address` | Yes | Receiver Algorand address |
| `label` | No | Payment label |
| `amount` | No | Amount in microunits (e.g. 1000000 = 1 ALGO or 1 USDC) |
| `asset` | No | ASA ID for asset transfers; omit or 0 for ALGO |
| `note` | No | Payment note |
| `xnote` | No | Exclusive immutable note |

**Returns:**
- `qr` — UTF-8 text QR code (terminal-friendly)
- `uri` — the `algorand://` URI string
- `link` — shareable hosted QR URL (via QRClaw service)
- `expires_in` — link validity period

**Channel-Aware Output:**

After calling `generate_algorand_qrcode`, tailor output to the channel:

**TUI / Web channels** (terminal, web UI, canvas):
1. **UTF-8 QR block** — paste the Unicode block characters from `qr` inside a code fence
2. **URI string** — the `algorand://` URI for wallet deep links
3. **Shareable link** — the hosted QR URL from `link`

Example:
```
[paste UTF-8 QR here]
```
URI: `algorand://...`
Shareable QR: [link URL]

**Social channels** (Telegram, Discord, WhatsApp, Signal, Slack, IRC, etc.):
- **Skip** the UTF-8 QR block — too bulky for chat
- Show only:
  - **URI string** — for wallet deep links
  - **Shareable link** — renders nicely in-app as a clickable QR image

## NFD Important Note

When using NFD (`.algo` names), always use the `depositAccount` field from the NFD response for transactions, NOT other address fields.

## Security

- **Mainnet = real value** — always confirm with user before mainnet transactions
- Never log, display, or store mnemonics or secret keys — use `wallet_*` tools for signing
- Verify recipient addresses with `validate_address` — transactions are irreversible
- Verify asset IDs on-chain and check verification tier with `api_pera_asset_verification_status` — scam tokens use similar names
