ActOnce Spend Gateway

Project Summary

ActOnce Spend Gateway is an open-source spending control layer for AI agents, built to help developers give agents purchasing power without handing over unchecked financial freedom. Designed for OpenClaw, Hermes, MCP-compatible agents, and Stripe Link for Agents, the site clearly explains a fast-emerging problem in the agent economy: prompts are not proper controls.

The website positions ActOnce Spend Gateway as a practical safety layer for agentic commerce, helping users define spend policies, block duplicate purchases, require human approval, and keep clear audit trails. It speaks directly to builders, agencies, and technical teams who want agents to take useful action while staying inside trusted financial guardrails.

Special Features

• ✓Policy-Driven Spending Controls: Users can define rules for spending limits, approved merchants, blocked categories, business hours, and duplicate purchase windows.
• ✓Local-First Open-Source Tooling: The free version runs locally, keeps policy files and logs on the user's machine, and is released under an MIT licence on GitHub.
• ✓MCP-Native Integration: Built for MCP-compatible agents, including OpenClaw, Hermes, Claude Code, Cursor, and other agent frameworks.
• ✓Human-in-the-Loop Approvals: Higher-risk purchases can be paused for approval, with support for Telegram alerts and approval workflows.
• ✓Duplicate Purchase Protection: SQLite-backed deduplication helps stop agents from making the same purchase twice within a configurable time window.
• ✓Zero Credential Exposure: The gateway does not handle payment credentials. It only returns clear decisions such as approved, rejected, or requires approval.
