Spending limits for AI agents. Create budgets, enforce limits, track spend across x402, cards, MPP, or any payment rail.

MCP services for agent security preflight, source scanning, injection screening, proof-of-work policy rehearsal, carbon accounting, climate disclosure and regulatory monitoring. Use each hosted endpoint in the README. Inspect a free quote before buyer-authorized x402/USDC payment. Includes free trust and settlement tools. Maxwell rehearsal does not activate runtime protection.

MCP Server for the LINE Shopping API, enabling AI agents and tools to interact with LINE Shopping data and operations via the Model Context Protocol.

MCP server that verifies storefront merchants before AI agents make payments, checking if the merchant is a real legal entity bound to the domain, and returning a PROCEED, ABORT, or REVIEW decision to prevent payment to clones or fraudulent stores.

Enables configuring and running StableOps Agent Payments while keeping secrets user-controlled, with wallet-pairing via user signatures and runtime payments through a user-operated signer sidecar.
