Algorand MCP Interaction
Interact with Algorand blockchain through the Algorand MCP server (126 tools across 15 categories).
Key Characteristics
- Agent-wallet signing — use
wallet_* tools to sign; the MCP server holds the mnemonics in a local SQLite DB and signs on your behalf. Mnemonics are never returned in tool responses.
- Multi-network — supports
mainnet, testnet, and localnet
Calling MCP Tools
MCP tools are deferred — you MUST use ToolSearch to load them before calling:
ToolSearch("+algorand wallet") # Search by keyword — loads matching tools
ToolSearch("select:mcp__algorand-mcp__wallet_get_info") # Load a specific tool by full name
Once loaded, call them normally:
mcp__algorand-mcp__wallet_get_info { "network": "testnet" }
mcp__algorand-mcp__make_payment_txn { "from": "ADDR", "to": "ADDR", "amount": 1000000, "network": "testnet" }
Full tool name pattern: mcp__algorand-mcp__<tool_name>. If you get "tool not found", use ToolSearch("+algorand <keyword>") to load it first.
Session Start Checklist
At EVERY session start:
- Load tools first: Call
ToolSearch("+algorand wallet") to load wallet tools — MCP tools are deferred and MUST be loaded via ToolSearch before use
- Check wallet:
mcp__algorand-mcp__wallet_get_info with target network — verify an account exists and is active
- If no accounts: Guide user to create one with
wallet_add_account (load via ToolSearch first)
- If needs funding: Generate ARC-26 QR with
generate_algorand_qrcode — returns { qr, uri, link, expires_in }. Display the qr text block and shareable link. Or direct to testnet faucet: https://lora.algokit.io/testnet/fund
- If needs USDC funding: Generate ARC-26 QR with
generate_algorand_qrcode — returns { qr, uri, link, expires_in }. Display the qr text block and shareable link. Or direct to testnet faucet: https://faucet.circle.com/
- Confirm network: Always confirm which network (
mainnet, testnet, localnet) before transactions
- Load additional tools as needed: Use
ToolSearch("+algorand <keyword>") to load tools for the task at hand
Network Selection
Every tool that touches the blockchain accepts a network parameter:
| Value | Description |
|---|
mainnet | Algorand mainnet (default) — real value, exercise caution |
testnet | Algorand testnet — safe for development |
localnet | Local dev network (requires ALGORAND_LOCALNET_URL env var) |
Default to testnet during development.
Pre-Transaction Validation
Before ANY transaction:
- MBR Check: Account needs 0.1 ALGO base + 0.1 per asset/app opt-in
- Asset Opt-In: Verify with
api_algod_get_account_asset_info before ASA transfers
- Fees: Every txn costs 0.001 ALGO (1,000 microAlgos) minimum
- Balance Check: Fetch current balance with
wallet_get_info or api_algod_get_account_info
- 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. Use api_pera_asset_verification_status to check verification tier before transacting unknown assets.
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.

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 (enforces limits) |
| 5 | send_raw_transaction | Submit signed transaction to network |
| 6 | Query tools | Verify result on-chain |
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 |
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 |
Best-Price Swap via Haystack Router (DEX Aggregator)
Haystack Router aggregates quotes across multiple Algorand DEXes (Tinyman, Pact, Folks) and LST protocols (tALGO, xALGO) to find the optimal swap route.
| Step | Tool | Purpose |
|---|
| 1 | wallet_get_info | Verify active account, check balance |
| 2 | api_haystack_needs_optin | Check if address needs opt-in for the target asset |
| 3 | wallet_optin_asset | Opt-in if needed |
| 4 | api_haystack_get_swap_quote | Preview best-price quote — show user output, USD values, route, price impact |
| 5 | User confirms | Always confirm before executing |
| 6 | api_haystack_execute_swap | All-in-one: quote + sign via wallet + submit + confirm |
CRITICAL — Swap direction (type parameter):
- "Buy 10 ALGO" → user wants exactly 10 ALGO out →
type: "fixed-output", amount = 10000000
- "Sell/swap 10 ALGO" → user spends exactly 10 ALGO →
type: "fixed-input", amount = 10000000
- "Buy USDC for 10 ALGO" → user spends exactly 10 ALGO →
type: "fixed-input", amount = 10000000
- Rule: "buy X of Y" = fixed-output. "sell/swap/use X of Y" = fixed-input. If ambiguous, ask.

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.

ARC-26 URI (1): generate_algorand_qrcode
Knowledge Base (1): get_knowledge_doc
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 Payment Workflow
Use the two algorand-mcp x402 tools to access x402-protected HTTP resources — the MCP tools handle transaction construction, signing, base64 encoding, and PAYMENT-SIGNATURE assembly internally. You only orchestrate the discover → select → pay flow.
Recommended supervised pattern (default)
-
Probe the endpoint to read what it costs:
x402_discover_payment_requirements {
baseURL: "https://example.x402.goplausible.xyz",
path: "/avm/weather",
method: "GET"
}
-
Inspect the returned accepts[] array. Pick the entry you'll pay with — usually the cheapest Algorand entry on the network you want, within budget. On mainnet, confirm the cost with the user before continuing.
-
Pay and fetch in one call, passing the pre-fetched requirements back so the tool doesn't re-probe:
make_http_request_with_x402 {
baseURL: "https://example.x402.goplausible.xyz",
path: "/avm/weather",
method: "GET",
paymentRequirements: <accepts[] from step 1>,
preferredNetwork: "testnet",
maxAmountPerRequest: 10000
}
Faster unsupervised pattern (testnet, known endpoints)
Skip step 1. Call make_http_request_with_x402 { baseURL, path, method } — it discovers, selects the cheapest affordable Algorand requirement, builds the atomic group, signs the payment leg with the active wallet, retries, and returns the resource. Always pass maxAmountPerRequest as a guardrail; pass preferredNetwork to pin testnet/mainnet.
Bazaar discovery (find paid resources to call)
Three tools query the facilitator's directory of cataloged paid resources:
bazaar_list { network?, method?, merchantId?, limit?, offset?, full? } — browse cataloged resources. Compact summary per item by default (URL, description, Algorand-payable accepts, popularity counters); pass full: true for verbatim records including discoveryInfo.bazaar_search { query, limit?, network?, includeTestnets?, scheme?, maxUsdPrice?, asset?, payTo?, extensions? } — keyword search with budget and asset filters.bazaar_get_resource_details { resource } — fetch a single resource by exact URL.
Then feed the chosen accepts[] (or the resourceUrl) into make_http_request_with_x402.
Always
- Mainnet = real money — confirm cost with the user before mainnet payments. Use
maxAmountPerRequest as a budget cap.
- Amounts are in atomic units. USDC has 6 decimals: 1,000,000 atomic units = $1.00.
preferredNetwork accepts mainnet | testnet | localnet; if omitted, the selector picks the cheapest affordable Algorand entry regardless of which Algorand network it's on.paymentRequirements is an ARRAY OF OBJECTS — preferredNetwork and maxAmountPerRequest are TOP-LEVEL siblings, not array members. The schema rejects malformed inputs with a specific message.

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 — scam tokens use similar names
