Let autonomous AI agents prepare checkouts and verify invoices without unchecked spending.
XPayr Agent Guardrails enforce per-transaction limits, daily rolling budgets, auto-approval thresholds, and chain whitelists across all 21 MCP tools.
AI Agent Guardrails mean an autonomous agent using @xpayr/mcp-server or POST https://xpayr.com/api/mcp operates strictly inside merchant-defined spending policies. Intents exceeding the auto-approval threshold are routed to the human approval queue before any wallet signature occurs.
01
Merchant defines per-tx cap, daily rolling limit, auto-approval threshold, and allowed networks.
02
AI agent submits a payment or settlement intent via MCP or REST API v1 (/api/v1/agent-intents).
03
XPayr policy engine evaluates the intent against active guardrails in real time.
04
Approved intents proceed to non-custodial execution; over-threshold intents enter the human approval queue.
Who pays gas?
MCP tool calls and policy evaluations are off-chain JSON-RPC 2.0 requests and consume zero blockchain gas.
Operational limit
XPayr never holds agent private keys or executes unlimited autonomous mainnet transfers without merchant policy authorization.
