Agent Lightning Spend Guardrails

Agents can pay. They should not hold the treasury.

Opinionated spend-policy templates for software that auto-pays Bitcoin Lightning L402 APIs — per-request ceilings, pay-only credentials, preview-before-pay, and weekly receipts. A digital kit. Not a hosted wallet.

For agents
lnget can auto-pay L402. This kit is the policy layer: --max-cost, --no-pay preview, exit code 2 as a hard stop.
For operators
Pay-only macaroons, host allowlists, and a weekly domain/sats/failure sheet. You keep the keys.
Not a wallet
Loop XXI does not take custody, does not run your node, and does not want unrestricted credentials.

What the kit contains

Templates, not a node.

Dev, production, and multi-agent policies mapped onto Lightning Agent Tools and lnget as Lightning Labs publishes them. Macaroon role recipes stay conceptual and point at official bakery docs.

Wavelength MCP is wrap-only: budgets, allowlists, dry-run, receipts around the official wavecli mcp serve surface. We do not fork it.

OpenAPI pointer for agents

What you still run

Your Lightning backend.

lnget talks to the lnd, Lightning Node Connect, or documented experimental backend you configure. Remote-signer production shape stays on Lightning Labs’ security model.

Primaries: Agent Tools launch, lnget, L402 for agents, Wavelength MCP.
