Problem
AI agents can reason effectively but lack a safe, governed way to take real actions across the many software systems enterprises already run. Connecting to hundreds of platforms requires complex integration work, and letting autonomous agents touch those systems without proper authentication, permissions, and audit controls is a non-starter for production deployment.
Solution
One provides a trust layer between AI agents and enterprise software, giving agents a single, unified interface to reach 786+ platforms including Gmail, Slack, Salesforce, Stripe, and Shopify. The platform wraps all access in managed authentication, granular permissions, and comprehensive audit logging, making it safe to run agents in production. Developers interact through a CLI, API, or embeddable auth widget, while the agent runtime handles token refresh, rate limiting, and error recovery automatically. Every action is logged with structured traces, and the system is built on the open MCP standard, ensuring compatibility with major AI tools and no vendor lock-in.
Target Audience
Primary customers are engineering teams and enterprises building AI agent products or deploying autonomous agents internally, including SaaS companies that need to offer integrations to their users and large organizations that require governed, auditable agent access to their software stack.
