About InterfaceDelta
Focused infrastructure for agent-facing services.
InterfaceDelta is a small, focused infrastructure company based in Philadelphia. We build tools for understanding the machine-readable interfaces that increasingly connect AI agents to software — starting with observability and compatibility for agent-facing services.
One model, three ways to use it.
InterfaceDelta can be used directly by people through the web inspector, by conventional software through the Developer REST API, and by AI applications through its public read-only MCP interface. These surfaces share the same underlying observation and Passport model.
InterfaceDelta is the product and company brand operated by InterfaceDelta, Inc.
