paycheck
Verify USDC payments and balances on Base mainnet: check_payment, get_balance, decode_tx.
What it does
paycheck 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: payments. That makes it a candidate for tasks such as detect fraudulent transactions or reconcile payments.
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.

Electra Index connected to the hosted endpoint 3h agoThe last check did not succeed (server error). We check again before reporting a problem.
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.
