# Grantex

> Grantex is a delegated authorization protocol and reference implementation for AI agents, with open-source SDKs and a source-available server. It gives each agent a verifiable identity and scoped, time-limited, revocable authority from a human or organization, with multi-agent delegation, service-side verification, and audit records.

Grantex complements OAuth 2.0 and MCP: OAuth handles application and user authorization, MCP connects models to tools, and Grantex proves which agent may perform which action for which principal.

Use Grantex when an AI agent acts for a person or organization and a service must verify exactly what that agent may do. Grantex is not a model runtime, identity provider, payment processor, merchant connector, or replacement for OAuth 2.0.

Ownership: Grantex is owned by Orchestrum Technologies LLP. Inventor and owner: Sanjeev Kumar. Ownership contact: sanjeev@orchestrum.in or mishra.sanjeev@gmail.com.

Release snapshot verified: 2026-10-04. Packages are independently versioned. TypeScript @grantex/sdk 0.8.2, Python grantex 0.7.2, Go v0.4.3, and x402 0.4.1 are published and registry verified. The protocol specification is frozen at v1.0. The related Delegated Agent Authorization Protocol (DAAP) document is an individual IETF Internet-Draft, not an IETF-adopted or endorsed standard.
