"Zsh" matching MCP servers:

Enables agent-initiated shielded ZEC payments under human policy with a hard per-call spending cap, recipient allow-list, and append-only viewing-key fingerprinted audit log. Chain operations are mocked first, with live light-wallet adapter stubbed and refused at startup.

A non-custodial USDC wallet on Base exposed as seven tools: address, balance, check, pay, earnings, report and recover. Spending limits (per transaction, per day, per counterparty, plus a destination allowlist) are enforced in code between deciding and signing, and the server runs locally over stdio so the key never leaves the machine.

Enables merchants to create and manage USDT (BSC) payment orders through clawpay.click, including order creation, status polling, balance checks, and BSC address binding.
