# Miro API + MCP (slim)

> Miro's REST API v2 reads and writes boards and board items (sticky notes, shapes, connectors, frames, cards, text, images, documents), tags and members, so an agent can lay out diagrams as well as notes.

**B · 65.3/100 · rank #175 of 452 · #2 in Design workspaces & canvases · not agent-ready · confidence medium**


Assessment: REST creates shapes, connectors and frames, so flowcharts and architecture sketches can be drawn directly. Legacy MCP board tools were removed nine days after the deprecation notice.

- Free tier: Free plan with 3 editable boards, REST API and 100 MCP calls a day, no card
- Rate limits: REST up to 100,000 credits a minute, 50 to 2,000 credits a call by level. MCP 100 to 10,000 calls a day by plan
- Auth scopes: OAuth scopes such as boards:read, boards:write, team:read, identity:read
- MCP server: Official, hosted at mcp.miro.com, 18 tools, 10 write and 8 read. Enterprise admins must enable it
- Export formats: REST board export is an Enterprise-only API. MCP reads a board as SVG

- Why: Reliability, incident.io status page with regional dashboards for the EU, US, Australia and Japan, and history (20). · Schema & documentation, OpenAPI spec in miroapp/api-clients per the 30 September check (25). · Agent ergonomics, 18 MCP tools, in the 11 to 30 band, and `canvas_read_as_svg` returns a whole board as SVG, which can be large (15 of 25). · Security & auth, REST uses OAuth 2.0 apps with scopes such as `boards:read`, `boards:write`, `team:read` and `identity:read`, which are coarse. · Payments & pricing, No machine payment protocol (0). · Maintenance & community, Changelog entry on 17 September 2026 (30). · Transparency & trust, Closed service under published terms.

## Before you call it

1. Create shapes first, then connectors with `startItem` and `endItem` ids
2. Put related items in a frame and set `parent` so they move together
3. Watch `X-RateLimit-Remaining`. There's no `Retry-After`, so back off exponentially on 429
4. Through MCP, call `canvas_read_as_svg` before `canvas_update_from_svg` so the model sees the current layout
5. Don't call the legacy MCP board tools. They were removed on 17 September 2026

```bash
curl https://api.miro.com/v2/boards -H "Authorization: Bearer $MIRO_ACCESS_TOKEN"
