Why the edge:
- Transparency & trust, Zeplin +38: 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.); Zeplin 60 (Closed service under published Terms of Service of 12 January 2026 and Developer Terms of 12 March 2025. The SDK and MCP server are MIT (17 of 30). The Privacy Policy of 29 August 2025 gives a general retention rule, a help article of 24 July 2026 sets two-year deletion periods for inactive data, and the AI terms rule out training on customer data. The security whitepaper of 7 July 2023 says no design data goes to third-party vendors, while the AI terms let third-party model providers process it as sub-processors, and the sub-processor list of 23 February 2024 names no model provider (16 of 30). The versioning page promises a new version for breaking changes, and the Developer Terms promise commercially reasonable efforts at advance notice with no period (8 of 20). The sub-processor list gives each entity's purpose and country, and the whitepaper states AWS hosting in the United States. The list is dated 23 February 2024 (15 of 20). Per the 9 October check, not re-read on 5 November, because Zeplin's Terms of Service bar automated access to its sites and services.)
- Schema & documentation, Zeplin +25: 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.); Zeplin 70 (Each of the 123 operation pages carries an OpenAPI 3.0.2 definition in its Markdown twin. No single downloadable description file was found linked (20 of 25). `llms.txt` and Markdown twins of every docs page (10). Operation descriptions are one line each, such as List all screens of the project, with nothing on when to use an operation (8 of 20). Parameters carry types, patterns, minimums, maximums, defaults, enums and required fields, as in the two operations read (13 of 15). Example responses and per-operation 404 and 422 answers with example messages, plus SDK code samples (11 of 15). The version is in the path with a written compatibility policy, but the changelog stops at 11 May 2021 while the reference now covers variables, flow boards and annotations (8 of 15). Two of the 123 operation pages were read in full. Per the 9 October check, not re-read on 5 November, because Zeplin's Terms of Service bar automated access to its sites and services.)
- Reliability, Zeplin +21: 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.); Zeplin 36 (Read with the hosted lines, because the API is a hosted service. No status page is linked from the home page, pricing page, docs or the help centre articles read, so the page and the incident record score as absent (0 + 0). The limit is published as 200 requests a minute per user (15). A 429 with the message Rate limit exceeded and three `Zeplin-RateLimit-*` headers, the reset time among them, are documented. No `Retry-After`, backoff guidance or idempotency keys were found (8 of 15). The pricing page lists a 24-hour priority support SLA for Enterprise, and the AI terms refer to Service Level Terms that were not found on the pages read (3 of 10). The API is at `v1` and is not marked beta (10). Per the 9 October check, not re-read on 5 November, because Zeplin's Terms of Service bar automated access to its sites and services.)
- Maintenance & community, UX Pilot MCP server +12: 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.); Zeplin 33 (Recency is scored on the last dated change to the API's own surface. The API changelog stops at 11 May 2021, and SDK 1.40.0 of 8 July 2026 is the last release that changed an API model, 120 days before 5 November, the same day as MCP server 1.0.6 (10 of 30). In the 90 days from 7 August, SDK 1.42.0 (15 October, an axios upgrade) and 1.43.0 (26 October, an `npm audit fix` lockfile change) are dependency-only and count half each, one in all (0 of 20). The docs name a Discord server and a developer email. The one issue on the MCP server repository, opened on 28 April 2026, was fixed on 8 July 2026, per the 9 October check (7 of 15). The JavaScript SDK is current, one official SDK (10 of 15). Both repositories keep a lockfile and the SDK took dependency upgrades on 5 and 22 October 2026, with a publish workflow and no test workflow in either (6 of 10).)
- Payments & pricing, Zeplin +10: 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.); Zeplin 30 (No machine payment protocol (0). Plan prices are public, $0, from $13.75 a month and $12 a seat a month on annual billing, with the API included and no per-call price (10 of 20). The Free plan costs $0 for one project, and the pricing page asks for no card for it (20). A person signs up in a browser and creates the token or app in their profile (0). Per the 9 October check, not re-read on 5 November, because Zeplin's Terms of Service bar automated access to its sites and services.)
- Agent ergonomics, Zeplin +9: 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.); Zeplin 55 (Scored for the API. Collections take a `limit` up to 100, with no field selection, and screen versions return whole layer trees. The MCP server trims this with `includeVariants` and `targetLayerName` (15 of 25). `limit` and `offset` pagination on collections, a section filter and a sort order on screens (16 of 20). Errors return `message`, `detail` and `code`, and each operation lists its 404 and 422 cases. No list of error codes was found (12 of 20). No idempotency keys or retry guidance for the create operations, and the four MCP tools set no readOnlyHint or destructiveHint (4 of 20). List calls need only a path ID. One official SDK, for JavaScript and TypeScript (8 of 15). Per the 9 October check, not re-read on 5 November, because Zeplin's Terms of Service bar automated access to its sites and services.)
