Optimizely Mark in Google Gemini Enterprise
Mark (Optimizely Agent Platform) is available in Google Cloud's Gemini Enterprise. Mark can leverage the Agent-to-Agent (A2A) protocol, which lets Mark exchange structured messages with other AI agents to coordinate complex, multi-step work inside a single workflow across vendors and frameworks.
Note
A2A is an emerging interoperability standard. Partners and capabilities can change. Expect rapid iteration across the ecosystem.
What you can do
- Interoperate across vendors – Connect Mark to third-party agents that implement A2A without building bespoke tool integrations.
- Compose multi-agent workflows – Orchestrate tasks across Mark agents and external agents to handle scenarios no single agent can manage alone.
- Keep security boundaries – Use protocol-level authentication and scoped credentials so each agent only accesses what it needs.
How it works
Gemini Enterprise exposes vendor-neutral A2A endpoints. Mark sends requests that include intent, inputs, and context, and the partner agent returns a typed response. Each request and response pair is a contract. Both sides agree on the message schema, auth method, and timeouts.
Requirements
- Gemini Enterprise access – A Gemini Enterprise project with A2A enabled. Contact your Gemini Enterprise administrator.
- Mark permissions – Access to configure agents and workflows in Mark.
- Credentials – A2A authentication details from the partner agent (for example, token or service account).
Configuration
See the Browse agents with Agents gallery article in the Google documentation for information on adding Mark to Gemini Enterprise. Or see Mark chat for Gemini Enterprise to install the Mark agent directly.
Limits and notes
- Ecosystem maturity – Not every vendor supports A2A yet; capabilities may vary.
- Rate limits – Partners may enforce quotas. Design workflows that queue or degrade gracefully.
- Tool compatibility – You can combine A2A with traditional tool integrations. Use A2A when a partner agent exists, and use tools when you need direct API control.
Note
If you use Opti ID, administrators can turn off generative AI in the Opti ID Admin Center. See Turn generative AI off across Optimizely applications.
