Miro’s relaunched Canvas (debuted at Miro’s “Canvas ‘26” event) is pitched not as a whiteboard but as a cloud-hosted, team-shared context layer that AI agents can read. Instead of each teammate maintaining their own local markdown files, the canvas holds many context types — markdown docs, mermaid diagrams, images, flowcharts, HTML prototypes, code — in one place that every team member’s agent connects to via MCP. You can act on that context with Miro’s own AI “sidekick” or with your own agent (Cursor or Codex) through the Miro MCP, so context stays identical across a team.
Key Takeaways
- The pitch is “one shared brain” instead of per-person markdown. Context lives in the cloud on a collaborative canvas so teammates’ agents all read the same source of truth, rather than each rebuilding context locally.^[inferred — framing synthesized from the video’s thesis]
- Context is multi-modal. A single canvas can hold markdown documents, mermaid diagrams, images, flowcharts, clickable HTML prototypes, and code — not just text files.
- Two agents can act on the canvas: (1) Miro’s built-in AI sidekick, and (2) your own Cursor or Codex agent connected through the Miro MCP / Cursor plugin.
- Demoed workflow: drop a PRD markdown file onto the canvas → ask the sidekick to research onboarding best practice as a new canvas doc → select the PRD + best-practice docs → generate an onboarding-steps document → generate an interactive HTML prototype on the canvas (clickable; preview via Play) → pull that prototype back into a code project via Cursor + Miro MCP to build it.
- Selection-scoping quirk (current limitation): the Miro sidekick only “sees” objects you explicitly select on the canvas; an MCP-connected Cursor/Codex agent can read canvas documents without manual selection.
- Team collaboration feeds the context. Comments and sticky notes added to the canvas become part of what the sidekick reads, so review notes (“change this to six steps”) are picked up as context.
- Cursor integration: install Miro from Cursor’s Customize/plugin marketplace, then type
@miroin the agent chat to read or modify the canvas; the demo built a light-mode prototype variant directly on the canvas from Cursor (using the cheaper “composer 2.5” model). - Maturity caveat: the feature is new and quirky — the sidekick added an unrequested document, and some Cursor-generated prototype output was “not 100% correct.” Expect rough edges.
Try It
- Open a Miro board and drag a markdown PRD onto the canvas; ask the Miro AI sidekick to summarize or expand it into a second document.
- Connect Miro to Cursor: Customize tab → search “Miro” → install the plugin, then
@miroin the agent chat to read and write canvas objects from your own agent. - Test the round-trip: have the sidekick generate an HTML prototype on the canvas, then ask your Cursor/Codex agent to “use Miro to update the app’s [feature] in line with the prototype in Miro.”
- For team context: add comments and sticky notes on canvas objects and confirm the sidekick incorporates them on the next generation.
