As AI becomes more tightly integrated into developer tools and platforms, companies like Canva are faced with a critical decision: how to support external developers in a way that’s scalable, responsive, and secure. While many platforms are leaning into autonomous AI agents, Canva took a different route — and chose an MCP (Multi-Channel Processing) server instead.
According to Canva’s head of ecosystem, the decision was driven not by limitations in AI, but by the specific needs of Canva’s growing developer base and the realities of building within a design-centric environment.
The Developer Experience at the Core
Canva has seen explosive growth in its third-party app ecosystem, which includes plugins for image editing, publishing, workflow automation, and more. As developers seek to build richer, context-aware apps inside Canva, the company needed an infrastructure that could:
- Handle multi-step requests efficiently
- Support dynamic front-end integrations
- Maintain consistent uptime and predictable responses
- Scale with real-time collaborative usage
While AI agents are great at decision-making and conversational logic, they tend to operate best in user-facing workflows, not necessarily backend infrastructure. The MCP server, by contrast, gave Canva more **direct control, visibility, and speed** in handling developer app requests.
What Is an MCP Server?
An MCP (Multi-Channel Processing) server acts as an orchestrator between Canva’s core services and external developer applications. It enables apps to receive structured requests, execute logic (locally or externally), and return data — all while preserving the performance, latency, and experience users expect from Canva’s interface.
Unlike AI agents, which are often unpredictable in how they interpret instructions or handle ambiguity, an MCP server can be tightly governed by:
- Strict input/output validation
- Defined schemas for app interaction
- Role-based authentication and throttling
Why Not an AI Agent?
While Canva does use AI in other areas — such as design suggestions, Magic Write, and image generation — using AI agents to interface directly with developer-built apps posed several concerns:
- Lack of determinism: Agents may respond inconsistently depending on training data or user phrasing
- Debugging difficulty: Developers need clear logs and predictable behavior during development
- Security and scope control: AI agents sometimes overstep intended roles if not properly sandboxed
Canva’s ecosystem team needed infrastructure that behaved like a traditional API gateway — but with added flexibility to support UI components, workflows, and developer-defined business logic. MCP checked all those boxes.
The Result: More Reliable Developer Integration
With the MCP server in place, Canva developers now have a robust way to connect their services, validate user input, and respond in real time inside the Canva UI — without sacrificing control or risking unexpected AI behavior.
This architecture also enables better support for:
- Collaborative app sessions in real time
- Structured multi-step flows like image editing + publishing
- Third-party data governance and rate-limiting
Final Thoughts
AI agents are powerful tools — but they’re not always the right ones for the job. In Canva’s case, the goal wasn’t to create an AI-driven assistant for developers, but to build a **reliable, transparent, and extensible platform** for app creation inside the Canva experience.
By choosing an MCP server over a conversational AI agent, Canva has given developers a fast, consistent, and controlled environment — one that scales with creativity, not complexity.
