Grantex

Grantex is an open-source delegated authorization protocol and reference implementation tailored for AI agents, focusing on verifiable agent identity, scoped and revocable authority, multi-agent delegation, and detailed audit records. Targeted at organizations developing or managing agentic AI systems, Grantex supports advanced authorization scenarios, including prepaid wallets, cross-wallet policies, and integration with both OAuth and Model Context Protocol workflows. It is intended for developers, infrastructure providers, and enterprise teams building secure agent-to-application and agent-to-agent delegation ecosystems.
