kubbi

Kubbi provides a specialized infrastructure solution for developers building agentic workflows and autonomous systems. It addresses the common challenge of passing large or sensitive data payloads between AI agents through standard communication channels like webhooks, message queues, or Model Context Protocol tools. By implementing the claim-check pattern, the platform allows developers to offload data storage while passing a secure, temporary URL through the primary message channel. This approach helps bypass size limitations often found in standard messaging protocols and prevents sensitive information from being permanently stored in communication logs. The service is designed with security and automation in mind, offering server-enforced features such as burn-after-read functionality and customizable expiration timers. Every payload is encrypted at rest using AES-256-GCM, ensuring that data remains protected throughout the handoff process. Additionally, a manifest preview feature allows receiving agents or systems to inspect metadata like file names and types before fully retrieving the content, which preserves retrieval limits. By centralizing the management of temporary data payloads, Kubbi simplifies the plumbing required for complex agent-to-agent interactions, allowing engineers to focus on the logic of their autonomous applications.
