One governed integration layer connecting your SaaS product and AI agents to every tool they need
Embed a single connect card in your product so customers link and configure their own apps without your engineers doing bespoke work.
Expose connected apps through one consistent schema, so your product and your customers work with the same data model.
Give agents scoped, audited tool access through the Model Context Protocol, with the same permissions and full logging.
Monitoring, retries, and automated fixes handle API changes and rotated credentials so maintenance does not land on your team.

One normalized API connects your product to hundreds of HRIS, payroll, ATS, CRM, accounting, ticketing, and file storage systems with read and write access.
Give agents secure, authenticated access to thousands of pre-built tools across third-party services, with scoped permissions and audit logs.
Route every model through one API with automatic failover, pre-built or custom routing rules, and spend and performance controls.
Distribute approved MCP connectors, models, and skills to employee AI tools with per-team budgets, DLP scanning, and audit logging.
