Why the edge:
- Reliability, Melius +54: Melius 69 (Graded on the hosted REST API and MCP server. status.melius.com runs on incident.io with component history for Web app and MCP, though it has no API component (20). Its history listed no incidents from July to 8 October 2026, as far back as the page went. 9 October to 4 November is unread, and a partly unread window keeps its recorded award (30). No rate-limit numbers are published. The docs say only that no plan has a monthly request quota and that bursts can return 429 (0). 429s carry `Retry-After` and a `retryAfterSeconds` body field, and the docs give a bounded retry policy and tell clients to check canvas or run state after a timeout or 5xx on a write. There are no idempotency keys (12 of 15). No SLA found (0). The API and MCP server carry no beta label, but the CLI is at 0.16.2 and Cast and media-URL inputs are marked beta (7 of 10). Per the 8 October check, not re-read on 4 November, because the terms of 30 October 2026 bar automated access to melius.com and its subdomains.); 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, Melius +34: Melius 56 (Closed service under terms effective 30 October 2026, read on 4 November, which name Melius AI, Inc. and Delaware law. The CLI package is MIT with no public repository (15 of 30). The new terms (section 5.6, no training of models on user input or outputs), the privacy policy and the pricing FAQ agree that user input and outputs are not used to train models, and say third-party model providers process content under their own terms without a guarantee from Melius. Retention is described as a reasonable period with no numbers, and no DPA was found (14 of 30). Deprecated models keep working for an unstated grace period with an in-app warning. No API deprecation policy found (5 of 20). No sub-processor list or hosting location found beyond a statement that data is processed in the United States (4 of 20). The privacy policy, deprecation and sub-processor readings are per the 8 October check, not re-read on 4 November.); 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, Melius +25: Melius 70 (Public OpenAPI 3.0.2 spec with 59 operations (25). llms.txt, llms-full.txt and a Markdown copy of every docs page (10). 58 of the 59 operations have a summary and no description. The MCP reference gives each of 75 tools one line, with ordering rules for `get_guide`, `show_presence` and `canvas_plan_layout`, and the tool definitions themselves need a signed-in client, so we didn't read them (8 of 20). Request bodies are typed with 336 enums, ranges, UUID formats and required fields, with 52 open `additionalProperties` objects (13 of 15). 401, 403 and 429 are declared on every operation and 400, 404 and 409 where they apply, but the spec has no examples and most error bodies are a bare `message` (9 of 15). The path is versioned at /api/v1 and the CLI states semantic versioning. No public changelog found (5 of 15). Per the 8 October check, not re-read on 4 November, because the terms of 30 October 2026 bar automated access to melius.com and its subdomains.); 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.)
- Maintenance & community, Melius +11: Melius 56 (The newest dated release is the CLI, 0.16.2 on 10 September 2026 per the 8 October npm reading, 55 days before this check. The vendor's Homebrew tap, whose bot tracks npm hourly, has no version after 0.16.2, and no other dated source could be read (20). Versions 0.15.0 to 0.16.2, eight in all, fall between 7 August and 10 September by the tap's bump commits, which match the 19 versions since 10 July in the 8 October npm reading (20). Closed service with no public changelog or issue tracker. Support is by email at support@melius.com and a Discord server linked from the site (5 of 15). There is no SDK library, though the CLI is on npm and Homebrew (5 of 15). The CLI has three dependencies, needs Node.js 20 and is published from GitHub Actions through npm trusted publishing. Its source is not public (6 of 10).); 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.)
- Agent ergonomics, Melius +5: Melius 51 (The MCP reference lists 75 tools, in the over-30 band, with `get_guide` and `get_docs` loading guidance on demand and 18 Cast tools shown only to teams with access (10 of 25). Four list operations take `limit` and `offset` and three take `search`, canvas content can be narrowed to one node or to media summaries, and the CLI has `--fields` (14 of 20). REST errors carry `statusCode`, `error` and `message`, the CLI adds a `code` and a `suggestion`, and `CANVAS_TOO_LARGE` is documented as not worth retrying. A shortage of credits arrives as a plain 400 (14 of 20). No idempotency keys, and we couldn't read MCP annotations without an account. The docs do give safe-retry guidance (5 of 20). Auto model selection and defaults keep required fields few. There is no SDK library, only the CLI and generated code samples in six languages (8 of 15). Per the 8 October check, not re-read on 4 November, because the terms of 30 October 2026 bar automated access to melius.com and its subdomains.); UX Pilot MCP server 46 (Tool count not published; grouped actions (10). Search by keyword and list calls (10 of 20). No documented errors (3 of 20). 'Nothing is deleted' by the organise tools, and deletes run only once the user confirms (15 of 20). OAuth or a key, no SDKs (8 of 15). 10 + 10 + 3 + 15 + 8 = 46.)
