MCP server for agent payments

Give your AI agent a wallet with a spending limit.

Connect a wallet you already own, set what an agent may spend, and hand it one MCP endpoint. It pays in USDC on Base on its own, never past your limits, never with your keys.

How it decides

Three bands, enforced by the server

Under auto-max

Executes from a capped on-chain allowance you granted. The token contract enforces the cap.

In the ask band

The agent gets a one-time link. You approve in your own wallet. Veyra verifies the receipt.

Over the limits

Blocked, with a reason the agent can relay. Daily caps and the recipient allowlist apply throughout.

Tools

What the agent can call

Tool	Purpose
`get_capabilities`	Rails, networks, assets, limits and allowlist in force right now
`get_budget`	Daily limit, spent today, per-payment limit, auto and ask bands
`list_payment_sources`	Masked sources and whether each can settle unattended
`create_payment`	Create a payment intent; the result says what the policy decided
`get_payment` / `list_payments` / `cancel_payment`	Track and cancel

Trust

Control plane, not custody

Veyra never holds funds. Above your auto-approve limit you sign every transfer yourself. Within it, a capped ERC-20 allowance does the work and you can revoke it any time. A simulated rail lets you wire everything up before touching real money, and it is labelled as simulated everywhere. Read exactly what you are trusting.
