OpenAI Agents SDK

Scope-enforced FunctionTool wrappers for the OpenAI Agents SDK.

Install

pip install grantex-openai-agents

OpenAI Agents SDK is a peer dependency:

pip install openai-agents

Quick Start

from grantex_openai_agents import create_grantex_tool

tool = create_grantex_tool(
    name="read_calendar",
    description="Read upcoming calendar events",
    grant_token=grant_token,       # JWT from Grantex authorization flow
    required_scope="calendar:read",
    func=get_calendar_events,
)

# Use with any OpenAI Agents SDK agent
from agents import Agent
agent = Agent(name="assistant", tools=[tool])

If the grant token doesn’t include the required scope, create_grantex_tool raises a PermissionError immediately — the tool is never created.
