  • Your OpenAI account has access to the models you plan to use (for example gpt-4.1, gpt-4o, or o1).
  • You have access to a Vijil team and permission to manage Keys and Agents.

Enterprises

If your organization uses enterprise-only features with Vijil:
  1. Add an MCP server URL so the agent can access MCP tools exposed by that server.
  2. Add an A2A Agent Card URL so this agent can participate in agent-to-agent workflows defined in your enterprise.
