Kite vs Miro API + MCP

Kite 33

Hosted reading, for the platform and its remote MCP server. No public status page was found. None is linked from the docs or the footer, https://kite.new/status answers 404 and status.kite.new does not resolve (0). No readable incident history, so the floor (5). Limits are published with numbers on the account page, 200 agent actions a day on Free, reset at midnight UTC, unlimited on Pro; 60 new files an hour; 20 comments on one file every 10 minutes; 600 exported layers an hour; 20 keys; file caps of 400 MB and 250,000 layers. auth.md says registration and agent calls are rate-limited without a per-minute figure (12 of 15). 429 is documented in auth.md with 'back off' and no Retry-After, 401 with a refresh-once-then-rediscover rule, and the drawing guide says to edit layers in place rather than redraw; no idempotency key on any write and no safe-retry guidance for layer_draw, so a retried draw adds a second frame (6 of 15). No SLA. The terms (8 September 2026) say Kite is provided as is, uptime is not guaranteed and files may be lost (0). The hosted server carries no beta label and the registry entry is 1.0.0; the product launched on 6 October 2026 and the desktop apps are 0.1.16 (10). 0+5+12+6+0+10 = 33.

Miro API + MCP 73

incident.io status page at status.miro.com with components (Application, Log in ability, MCP server, Web Site, Mail System, Billing) and history (20). In the 90 days from 4 August the history lists intermittent registration and login problems on 31 August and username-and-password sign-in unavailable on 9 September, both login only, and a scheduled CDN maintenance notice on 3 October, with no API, board or MCP incident (20 of 30). REST limits are published as credits, 100,000 a minute with calls costing 50 to 2,000 credits by level, and MCP calls are capped per day by plan (15). 429s return a JSON body with code: tooManyRequests and X-RateLimit-Limit, -Remaining and -Reset headers, and the docs advise exponential backoff. No Retry-After and no idempotency guidance for creates (10 of 15). No SLA found (0). REST v2 is GA. We didn't see a beta label on the MCP tools page, but didn't confirm the server's status either (8 of 10). 20 + 20 + 15 + 10 + 0 + 8 = 73.

Kite 44

Closed service. The terms of use (8 September 2026) run to about 200 words on content, prohibited use, links, availability and changes and name no legal entity, address or governing law, so the contracting party is unknown (8 of 30). The privacy policy (14 October 2026) names eight services, says files are not read, trained on or sold, discloses masked session replays and error replays, gives the agent token's 7-day life renewable to 90 days (matching auth.md and the integration page), the 30-day purge of deleted pages and the one-month deletion of a closed account's files, and the Figma token's handling; no DPA and no retention period for logs beyond the providers' own (20 of 30). No deprecation policy or dated notices; the terms promise email or in-app notice of changes that matter and the changelog dates additions, not removals (4 of 20). Telemetry (PostHog, Sentry) is disclosed with what it excludes and no opt-out beyond product-news emails; service locations are given only for PostHog and Sentry (US) (10 of 20). 8+20+4+10 = 42.

Miro API + MCP 77

Closed service under published terms. The miro-ai plugins and skills are MIT (17 of 30). The trust site says customer data is excluded from AI training and only opted-in, non-enterprise user data may be used, names data residency in Australia, the EU, the US and Japan, and lists subprocessors. We didn't read retention periods (22 of 30). Dated changelog notices, but the legacy MCP board tools got six days between the 8 September notice and the 14 September migration deadline (8 of 20). Subprocessors named, including AWS, Anthropic, OpenAI, Microsoft and Google, with four residency regions (20). 17 + 22 + 8 + 20 = 67.

Kite 62

MCP reading, since the MCP server is the only surface an outside agent reaches. No tool input schemas were read. The server card at /.well-known/mcp/server-card.json declares tools without listing them, and llms-full.txt describes every tool in prose with argument names in the skill, so typed inputs are the vendor's to show and were not seen (10 of 25). llms.txt, llms-full.txt, skill.md, auth.md and pricing.md are served as text and Markdown (10). Descriptions say what each tool does and when to use it, such as file_search over file_list when the user describes a file, layer_edit rather than redrawing, never base64 in HTML, never a picture of a design, guide_read's six topics, and the view-only rule (16 of 20). Inputs named in the docs are typed in prose, with enumerations for audience (link, restricted), export formats (svg, react, tailwind, html), sticky colours, shader bases and guide topics, and bounds for videos (100 MB) and fonts (4 MB), but the main write tool takes one HTML string and layer_edit a free CSS object (8 of 15). Worked HTML examples in skill.md, a prompt per client page, and auth.md's 401, 400 and 429 responses; no example tool call or response and no MCP error shape (8 of 15). A dated changelog with 15 entries from 6 October to 1 November 2026 that names agent-facing changes (page, version, comment and export tools on 25 October), server version 1.0.0; no versioned tool surface or deprecation policy (10 of 15). 10+10+16+8+8+10 = 62.

Miro API + MCP 85

OpenAPI spec in miroapp/api-clients, v2.0 with 114 paths and 197 operations, last updated 22 April 2026 (25). llms.txt at developers.miro.com, and every docs page has a Markdown twin (10). The MCP tools page (updated 28 October 2026) lists 52 tools with one-line descriptions, and a canvas_get_canvas_composer_skill tool hands the model drawing guidance, but the server is closed and we couldn't read its tool definitions (12 of 20). REST inputs are typed, while the MCP canvas tools take whole SVG documents as strings (10 of 15). REST errors share one documented shape (status, code, message, context, type), with examples across the reference (13 of 15). Dated changelog with an RSS feed and a versioned v2 API (15). 25 + 10 + 12 + 10 + 13 + 15 = 85.

Kite 50

OAuth 2.1 with the authorization code flow, PKCE S256, dynamic registration of public clients, 7-day access tokens, 90-day refresh tokens that rotate on every use and revoke the connection if replayed, a revocation endpoint, bearer in the header only, and per-connection disconnect in Settings; one scope, pages, with the agent working under the user's full rights, and API keys that are per tool and revocable but unscoped (24 of 30). Least privilege comes from the file, not the token. A file shared view-only lets an agent read and comment but not draw, comment and download settings apply to agents, an agent cannot delete a file for good or touch the account, workspace or people, and each Mac-run request reaches only its file; no read-only mode on the hosted server and no confirmation for layer_remove, page_remove or version_restore (12 of 20). Comments, skills written by any editor, captured web pages and Figma pastes reach the model. The skill says a file's skills apply to that file only and never to sharing or people, and the Mac docs keep Agents Run Any Tool off by default because an agent reads comments and web pages and one could try to trick it; no guidance for the hosted server's own tools (8 of 15). Settings, Agents lists each connected app and key with when it connected and was last used, the board shows the agent's name while it works, and version history records agent saves; no per-call log for the operator (6 of 15). No security.txt (404), disclosure policy, bug bounty, SOC 2 or ISO 27001; SSO and SAML on Team (0 of 20). 24+12+8+6+0 = 50.

Miro API + MCP 67

REST uses OAuth 2.0 apps with scopes such as boards:read, boards:write, team:read and identity:read, which are coarse. The MCP server uses OAuth 2.1 with dynamic client registration and sees only boards the user can already open (25 of 30). A boards:read token gives read-only REST access, and Enterprise admins must switch MCP on, org-wide or for chosen teams. The MCP server has no read-only mode, and the 52 tools now include section_delete, a canvas_update_from_svg that creates, updates and deletes items, and tools that share boards and spaces and change roles, so the earlier point for having no delete tool is gone (10 of 20, was 13). Sticky notes, comments and board text written by collaborators reach the model through canvas_read_as_svg and comment_list_comments, and import-claude-design-from-url fetches a public URL; we found no prompt-injection guidance (3 of 15). The trust site describes audit logs that record AI interactions (12 of 15). ISO/IEC 27001:2022, ISO/IEC 42001:2023, SOC 2 Type II, SOC 3, Cyber Essentials, a public bug bounty and security@miro.com on the trust site. No security.txt (miro.com/.well-known/security.txt answers 404) (17 of 20). 25 + 10 + 3 + 12 + 17 = 67.

Kite 78

Closed service with a dated changelog. The latest entry is 1 November 2026 (30). 15 dated entries between 6 October and 1 November 2026, including Pro on 18 October, Windows, shaders and website design systems on 23 October and the agent page, version, comment and export tools on 25 October (20). Support is hello@kite.new, a Support link in the docs, 'your feedback first in line' on Pro and dedicated support on Team; no community channel, forum or issue tracker, and the plugin repository has no issues (8 of 15). new.kite/kite 1.0.0 is in the official MCP registry under a DNS-verified namespace since 21 October 2026 (15). No packages to judge; the MIT plugin repository was pushed once on 7 October 2026 and the desktop apps update themselves (5 of 10). 30+20+8+15+5 = 78.

Miro API + MCP 67

The newest changelog entry is 17 September 2026, 46 days before 2 November, so the recency line is in the within-90-days band (20 of 30, was 30, cause time). Four dated entries since 4 August, on 12 and 19 August and 8 and 17 September; the MCP registry entry (1.0.2, 6 March 2026) and the Node client (2.2.4, February 2025) add nothing in the window (20). Closed service with a public changelog and a developer community. The miro-ai repository of plugins and skills last had commits on 16 and 17 September (10 of 15). io.github.miroapp/mcp-server is in the official registry under a GitHub-verified namespace, latest 1.0.2, but the Node client hasn't had a release since February 2025 (13 of 15). Node client stale for 21 months; the api-clients repository gets only dependency bumps (4 of 10). 20 + 20 + 10 + 13 + 4 = 67.

Kite 44

MCP reading. 59 tools (61 through the Mac app) with no toolsets, read-only subset or dynamic loading; guide_read moves the long instructions out of tool descriptions into on-demand reads, but tools/list still carries 59 definitions (5 of 25). Output is sized by asking for one page in file_outline, one node in layer_source and layer_render, layer_search by name, words or type, file_search over content, comment_list with unread_only and include_resolved, request_list per file; file_list is newest-first with no documented paging (14 of 20). OAuth errors are documented with recovery steps, web_capture says when a page was cut short and an unknown shader base is refused, but a picture Kite cannot fetch is left out silently and no tool error shape is documented (9 of 20). No readOnlyHint or destructiveHint documented and no idempotency keys; version_save before a big change and version_restore undoable both ways, file_archive reversible and no permanent delete, layer_draw's replace argument for swapping a node (7 of 20). Few required parameters (file_new takes a title, layer_draw a file and HTML, finish_working a file), defaults in the drawing guide, and an MIT plugin repository for Claude Code, Codex, Cursor and Grok Bot; no SDK, since the vendor points at the official MCP SDKs (9 of 15). 5+14+9+7+9 = 44.

Miro API + MCP 53

The MCP tools page now lists 52 tools (24 read, 28 write), up from 18 on 1 October, which is the more-than-30 band. No toolsets, dynamic loading or read-only subset is documented, and the FAQ says restricting which tools may connect is still evolving (5 of 25, was 15). REST lists page with limit and cursor and filter by item type, and board_search_boards and canvas_search find boards and items over MCP (18 of 20). Errors carry a machine code and message (16 of 20). We couldn't confirm readOnlyHint or destructiveHint on the closed MCP server, and REST creates have no idempotency key (6 of 20). The official Node client, @mirohq/miro-api 2.2.4, was last released on 5 February 2025 (8 of 15). 5 + 18 + 16 + 6 + 8 = 53.
