Palantir and Zeta Global announce strategic partnership.Read News
Recently, I spoke with a marketing director who had invested heavily in a legacy cloud platform, only for it to become obsolete within months.
Her story isn’t unique. New AI innovations are becoming table stakes at a pace that leaves many marketers feeling constantly behind. At Zeta, we recognized this challenge early and decided to architect our platform with flexibility and adaptability at the core.
Following the launch of our AI Agent Studio, we’ve continued to push forward by integrating both Model Control Protocol (MCP) and Google’s Agent-to-Agent (A2A) framework. But unlike many vendors who anchor their systems to a single standard, we’ve chosen to build a protocol-agnostic infrastructure from the ground up.
Think about furnishing your first apartment. You could commission custom furniture tailored to a specific layout, or you could buy well-designed modular furniture that adapts when you inevitably move. Our protocol-agnostic approach follows that second philosophy.
In practical terms, this means your marketing systems won’t become obsolete when new AI standards emerge. Your team can integrate new tools and models without scrapping existing investments or starting from scratch. The platform you buy today grows with you tomorrow without requiring a complete replacement.
Many people mistakenly view protocols like MCP and A2A as competing standards when they actually complement one another.
MCP creates standardized connections between language models and external tools through a JSON-RPC interface. This lets AI agents perform actions like pulling data directly from your databases, interacting with your cloud services, and executing commands based on real-time information.
A2A allows multiple AI agents to coordinate their activities. With A2A, agents can delegate specialized tasks, collaborate with one another, and streamline complex workflows to unlock more sophisticated automation scenarios.
The result is an expanded set of use cases that lets marketers do more without worrying about what’s around the next corner.
Let’s look at a few practical examples of how MCP and A2A can work together to solve problems for marketers.
A CPG brand is preparing a back-to-school campaign. An orchestrating agent, coordinated via A2A, first taps into historical transaction data using MCP-connected platforms like Snowflake or the ZMP.
Next, it triggers a forecasting agent that runs a predictive model to pinpoint the most profitable segments. Finally, another agent automatically fine-tunes media buys and creative targeting, focusing on segments predicted to deliver the highest returns.
This automated approach replaces weeks of manual data crunching and segment selection.
A performance marketing team needs to adjust their budget allocations across paid search, email, and connected TV (CTV). Using MCP, a forecasting agent pulls real-time internal performance data and feeds it into an econometric Marketing Mix Model (MMM).
An explainability agent translates the model’s results into straightforward budget recommendations—like reallocating 12% of the paid search budget to CTV in specific regions, transforming marketing mix modeling from a slow quarterly chore into an agile, daily practice.
A retailer needs to quickly launch a flash sale via email, SMS, and their website. An A2A kicks of the agent sequence by using a content generation agent to draft persuasive promotional copy through MCP-connected LLM services like OpenAI or Claude.
Then another agent identifies the ideal audience segments using the ZMP API data, also accessed through MCP. Finally an activation agent deploys the campaign across selected channels.
A travel company needs to provide immediate personalized offers to users who share minimal data. Upon form submission or session initiation, an agent uses MCP to enrich user profiles by pulling internal user history, querying third-party enrichment services (like Clearbit or FullContact), and accessing interest-based recommendation models.
This enriched data powers real-time personalized experiences across the website or via email, without any manual delays.
A B2B SaaS company needs an efficient way to score leads from multiple sources and automatically direct them to the appropriate next steps. An inference agent, using MCP, quickly pulls structured lead data, enriches it, and runs it through a predictive scoring model. An explanation agent then highlights key insights behind the scores, like identifying high-intent fintech prospects requesting demos.
Finally, a coordinating A2A agent routes the leads. Top-scoring leads go straight to sales calls while medium scores enter email nurture sequences.
We built every capability in Zeta with secure API endpoints that connect directly to your existing data environment. AI models work together across workflows with proper authentication and access controls protecting every interaction.
This approach lets you start small with focused applications and expand naturally as needs change. You avoid the common trap of buying something that solves today’s problem but creates tomorrow’s limitation.
Hundreds of MCP servers already exist for popular systems like PostgreSQL, Snowflake, Slack, Docker, Kubernetes, and Todoist. But new standards will emerge and inevitably replace or extend what exists today.
When that happens, Zeta’s modular architecture will allow us to integrate new innovations without a major pivot. This means that your marketing operations maintain continuity without disruptive migrations. We’re focused on business outcomes rather than specific technologies which means we prioritize what marketers need to accomplish rather than dictating which tools they need to use.
Zeta lets you leverage models that work best for your specific needs, connect to data sources you already maintain, deploy anywhere that meets your requirements, and scale as your business grows.
No one knows exactly what marketing technology will look like in five years. The only certainty is change. The best way to keep pace is to build systems ready to evolve.
We’ve seen too many marketing teams trapped with rigid platforms that can’t keep pace with new developments. Our protocol-agnostic approach ensures your tools evolve alongside new standards without painful transitions. You spend less time and money on system migrations, adapt more quickly to market shifts, and gain advantages over competitors locked into inflexible systems
