Why the edge

Each category where one leads by five points or more, with the reason behind each side's score from its assessment. The numbers are in the table below; this is what they stand for.

Reliability Miro API + MCP +58

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.

UX Pilot MCP server 15

No status page found (0). No history (5). No limits found (0). No retry guidance (0). No SLA (0). Not labelled beta (10). 0 + 5 + 0 + 0 + 0 + 10 = 15.

Transparency & trust Miro API + MCP +55

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.

UX Pilot MCP server 22

Terms and privacy render with script and weren't readable (0). Data handling not read (0). A tool that maps old tool names to new calls eased the 3.0 change, no dates (5 of 20). Subprocessors not found (0). 0 + 0 + 5 + 0 = 5.

Schema & documentation Miro API + MCP +40

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.

UX Pilot MCP server 45

Schemas not read without sign-in (15 of 25). No llms.txt read (0). Tools grouped by job (find, organise, delete, import, review, React), with a help tool that maps old names to new calls (14 of 20). Inputs not verifiable (5 of 15). A tool that returns any action's fields with an example (8 of 15). Registry 3.0.0 on 4 November; no changelog (3 of 15). 15 + 0 + 14 + 5 + 8 + 3 = 45.

Security & auth Miro API + MCP +28

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.

UX Pilot MCP server 39

OAuth or a bearer key; scopes not published (20 of 30). Organise tools never delete, and deletes need confirmation (14 of 20). Imported AI output and comments are third-party text; no injection guidance (3 of 15). No audit log (0). No security programme found (2 of 20). 20 + 14 + 3 + 0 + 2 = 39.

Maintenance & community Miro API + MCP +22

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.

UX Pilot MCP server 45

Registry 3.0.0 and repository on 4 November 2026 (30). Dated releases not found (0). Issues not read (0). Official registry entry ai.uxpilot/uxpilot (15). README-only repository (0). 30 + 0 + 0 + 15 + 0 = 45. Registry presence read from Anchor Terminal's own daily import of the official MCP registry (/api/v1/registry.json, 6 November 2026), not the registry's API.

Payments & pricing Miro API + MCP +10

Miro API + MCP 30

No machine payment protocol (0). Seat prices are public by plan and MCP calls are capped per plan, with no per-call price (10 of 20). Free plan with 3 editable boards, the REST API and 100 MCP calls a day, and a 14-day Business trial; no card for the Free plan per the 30 September check (20). A person creates the OAuth app or approves the MCP sign-in in a browser (0). 0 + 10 + 20 + 0 = 30.

UX Pilot MCP server 20

No machine payment protocol (0). Pricing behind script, not read (0). Free tier (20). A person signs up (0). 0 + 0 + 20 + 0 = 20.

How the scores have moved

Verdicts

Miro API + MCP

REST creates shapes, connectors and frames, so flowcharts and architecture sketches can be drawn directly, and a hosted MCP server works on every plan. The MCP server now exposes 52 tools, including sharing and delete tools, with no read-only mode, and legacy board tools were removed nine days after notice.

UX Pilot MCP server

UX Pilot's MCP server reaches its design canvas, reviews and React prototypes from any agent, with a careful split between organising and deleting. Little else is public, no status page, limits, errors or readable legal pages.

Before you call either

Miro API + MCP

  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; an update applies a diff and can delete items missing from your SVG
  5. Ask before calling board_share, space_share, role updates or section_delete, which change who can see work or remove it

UX Pilot MCP server

  1. Ask the help tool for an action's fields before calling it
  2. Delete only after the user confirms
  3. Treat imported AI output and comments as untrusted

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
