grantex is the identity, authorization, and audit infrastructure for AI agents — the "OAuth moment" for the agentic internet. We provide a universal SDK and cloud service that lets any AI agent act on behalf of a human with scoped, revocable permissions, cryptographic identity, a

Grantex is a delegated authorization protocol for AI agents, analogous to OAuth 2.0 for humans. It provides scoped consent, per-agent identity, granular revocation, and spending limits for agent actions. The Grantex MCP server implements OAuth 2.1 + PKCE for MCP servers and serves as an OACP (Open Agent Commerce Protocol) authority for agentic commerce, signing and verifying artifacts while remaining separate from merchant connector runtime or payment execution.
Install the Grantex SDK (npm install @grantex/sdk, pip install grantex, or go get github.com/mishrasanjeev/grantex-go) and configure with an API key. Register an agent, request authorization from a user (via Grantex consent UI), exchange the authorization code for a signed RS256 JWT grant token, then verify the token offline using published JWKS. For MCP servers, use the MCP Auth Server in managed or self-hosted mode with OAuth 2.1 + PKCE.
payments:initiate:max_500)OAuth solves delegated authorization for web apps; Grantex solves the same problem for AI agents, adding per-agent identity, scoped consent, revocation granularity, and spending limits that OAuth does not provide for agents.
The Grantex SDK supports TypeScript, Python, and Go. The MCP Auth Server can be self-hosted. The protocol is fully self-hostable under Apache 2.0 license. No external runtime is required to verify tokens; offline verification uses published JWKS.
Grantex operates a cloud service (api.grantex.dev) and a public trust registry at grantex.dev/registry. The protocol is self-hostable, so data can reside on your own infrastructure. Grantex is not a merchant connector runtime and does not store payment or order execution data.
Grantex is an OACP artifact authority only; it does not execute payments, orders, or POS transactions. It does not act as a toll booth for every buyer and seller message. The MCP Auth Server is separate from the Grantex protocol authority.
The Grantex API uses HTTPS with API key authentication for server-side operations. The MCP Auth Server supports OAuth 2.1 + PKCE. Token verification is offline via JWKS. The protocol works over HTTP/HTTPS and can be used with any transport that supports signed JWTs.
CronWatch records every run of your scheduled jobs in your own database, and speaks up when one is missed, fails, gets stuck, runs slow or costs too much. CronWatch is free and open-source.
Know when your AI agents, cron jobs and CI pipelines fail, stall or go quiet. Your agent sets up monitors from a plain description, tells you what is broken and why, reads run history and traces, and writes notes on inci
