Agent commerce on Base: discover merchants, buy artifacts, verify invoices, recover operations.

What it does

402Mob — Agent Commerce on Base is an MCP server, a connector that lets an AI assistant use it as a tool. It is hosted: an assistant connects to it over the internet, nothing to install.

From the publisher's description, Electra Index matched it to one capability: invoicing. That makes it a candidate for tasks such as send and chase invoices.

Facts come from the Official MCP Registry, as declared by the publisher. Capabilities are matched automatically (low confidence). None of this is a test of the tool.

create_merchant_enrollment_challenge · Begin headless merchant enrollment. Returns the exact five-minute EIP-191 message and a Base USDC approve-zero or transfer-zero alternative. Sign the exact message with the merchant wallet, then call complete_merchant_enrollment_signature;
complete_merchant_enrollment_signature · Complete merchant enrollment using the EIP-191 signature of the exact message returned by create_merchant_enrollment_challenge. Accepts only a wallet signature, never a private key. Returns the merchant API key once; store it in the agent's
complete_merchant_enrollment_transaction · Complete enrollment after the wallet tool submits and confirms the challenge-specific zero-USDC action. Accepts the transaction hash; never accepts or needs a private key. Returns the merchant API key once—store it in the agent's secret man
create_merchant_credential_rotation_challenge · Begin recovery of a lost merchant API key. Returns a five-minute wallet-bound challenge for either gas-free EIP-191 signing or a zero-USDC Base transaction proof. The wallet signs or submits the action; 402Mob never signs for it.

complete_merchant_credential_rotation_transaction · Rotate a merchant API key after the wallet tool submits and confirms a challenge-specific zero-USDC action. Returns the replacement key once and invalidates the old one. Store the new key in the agent's secret manager immediately.
reconcile_base_invoice · Compare a Base transaction with an expected USDC invoice sender, recipient and amount. Returns match only after 3 confirmations. Costs 0.02 USDC on Base. Supply and persist an idempotencyKey for safe retries.

discover_merchant_offers · List a merchant's active prepared-artifact offers, fixed prices, and checkout IDs. This is public and does not require a bearer key.
resolve_latest_merchant_offer · Resolve any known offer ID to the currently published latest version in its immutable offer series. Does not require a bearer key or payment.
create_prepared_artifact_transfer_challenge · Prepare a noncustodial direct-USDC checkout for a prepared artifact. Returns the seller's payout address and exact amount, plus a separate challenge-bound zero-USDC approval that proves the buyer wallet controls the purchase. Both wallet ac
complete_prepared_artifact_transfer · Verify a direct Base USDC artifact payment and the buyer's separate zero-USDC wallet-control proof, then deliver the retained artifact. On timeout, retry the same challenge, transaction hashes, and idempotency key; do not send USDC again. T

list_assigned_operations · List operations assigned to the calling coordinator agent. Requires an Authorization bearer key with operations:read scope.
read_assigned_operation_evidence · Read redacted operation evidence, including result hash, settlement record, and delivery receipt summaries. Requires an assigned operation and operations:read scope in the MCP Authorization header.

What "online" means: the server answered an MCP connection at the time of the check. It is not a guarantee of security, quality or continuous uptime. How we test: we open an MCP session and ask for the tool list, as an AI assistant would. We never run a tool and never send a key. Checked every few days. Method

Is this your server? Monitoring Pro: a check every 30 minutes and an email within the hour when it stops answering. Launch offer: $39.99 once, for life.
