tx402-mcp

tx402 MCP

Use tx402 from any MCP-compatible AI client to explain Algorand transactions, complete atomic groups, transaction batches, and recent account activity.

Tools:

• explain_algorand_transaction
• explain_algorand_atomic_group
• explain_algorand_transaction_batch
• summarize_algorand_account_activity

Run

npx tx402-mcp

The safe default does not spend funds. When the paid API returns HTTP 402, the tool returns the payment requirements to the agent.

To let the MCP client pay from a local wallet, configure a funded Algorand wallet file and explicitly enable Mainnet spending:

$env:TX402_MCP_ENABLE_PAYMENTS="1"
$env:BUYER_WALLET_FILE="C:\path\to\buyer-wallet.json"
$env:CONFIRM_MAINNET_PAYMENT="1"
npx tx402-mcp

The wallet file stays local. tx402 never receives its mnemonic or private key; the MCP process signs the x402 payment client-side.
