Verdicts
Bannerbear API + MCP
Hosted MCP server with OAuth and tool groups chosen by URL path, 30 tools by default, 8 on /workflows, 63 on /all. Privacy policy and terms last updated on 29 June 2021, with no retention periods and two named third parties.
Canva REST APIs + MCP
OpenAPI 3.0 with 59 described operations, per-user rate limits and a 78-value error code enum. No server-to-server key, so unattended batch rendering has to run under one user's OAuth grant.
Before you call either
Bannerbear API + MCP
- Connect to mcp.bannerbear.com/workflows or a comma-separated group path instead of /all, which loads 63 tools
- Treat 402 as spent quota and 429 as the 60 POST per 10 second limit, and back off yourself since no Retry-After is sent
- Use sync.api.bannerbear.com only for /v5/images, and expect a 408 after 10 seconds
- Ask for one format at scale 1 unless you need more, since jpg plus png at scale 2 costs 4 credits
- Create a V5 key (bb_ak_v5_) for V5 endpoints, since V2 keys are refused there
Canva REST APIs + MCP
- Call the user capabilities endpoint before autofill, brand templates or resize, which need Pro or above
- Poll export, upload and autofill jobs with exponential backoff and download results within 24 hours
- Commit an MCP editing transaction after perform-editing-operations, or the changes don't land
- Expect license_required on export when a design holds premium elements
- Read
page_number, not the deprecatedindex, from Get design pages
