ONES vs Plane

ONES 25

Graded as a hosted service on ONES.com Cloud's Open API and MCP server. No status page is linked from ones.com, the trust centre or the docs, and status.ones.com did not resolve (0). With no readable history the incident line scores 5. No rate limit with numbers was found in the developer docs index or the terms, which only reserve the right to restrict excessive traffic (0). No 429, backoff or idempotency guidance found (0). The pricing page states 99.9% uptime on Business and 99.95% on Enterprise (10). The MCP server has been in the release notes since 6.42.0 on 26 August 2025 and carries no beta label (10). 0 + 5 + 0 + 0 + 10 + 10 = 25.

Plane 89

Graded on the hosted MCP server and the Plane Cloud REST API, with the hosted lines. Status page at status.plane.so on incident.io with six components, API among them. The MCP server is not a component (20). Re-read on 1 November 2026, the page's 90-day window lists no incident and every component at 100 per cent. The one event is a payment-system maintenance window on 11 October, posted on 9 October and complete the same morning (30). API v1 is limited to 60 requests a minute per key. API v2 has per-token buckets with no number published, and no MCP limit was found (12 of 15). v2 returns 429 rate_limited with Retry-After and tells clients to wait that long, and v1 sends X-RateLimit-Remaining and X-RateLimit-Reset. No idempotency keys found (10 of 15). The SLA of 9 April 2026 sets 99.5 per cent monthly uptime with credits on Business and Enterprise (10). Neither surface is marked beta, but the MCP server is at 0.3.x and replaced its whole tool list in 0.3.0 on 14 August 2026 (7 of 10).

ONES 40

Scored on the MCP server and the Open API together. 67 MCP tools load by default (5), and a client granted fewer scope groups is limited to fewer tools (5 back). Lists take limit and cursor with project and issue type filters, and query_issues_by_onesql runs a filtered query (15 of 20). Error status codes are documented per endpoint with response schemas, but no error code catalogue was found (8 of 20). No idempotency keys or MCP annotations found (0). One official SDK, @ones-open/node-sdk, aimed at ONES Apps, and the MCP setup is one mcp-remote line (7 of 15). 10 + 15 + 8 + 0 + 7 = 40.

Plane 78

30 MCP tools, about 67,000 characters by the repository's count, down from 177 before 0.3.0 (15). No toolsets or read-only subset, though list and retrieve actions take fields and per_page (2 more, 17 of 25). Cursor pagination, PQL filters, order_by, ?fields= and ?expand= on both API versions and on MCP list actions (20). v2 errors are problem+json with a stable code and per-field entries, and the MCP server names missing arguments and plan-gated functions. v1 errors are plain status codes (17 of 20). readOnlyHint and destructiveHint are set per tool from its actions, so a tool with one delete action is marked destructive as a whole and idempotentHint is false throughout. No idempotency keys (10 of 20). workitem create needs only project_id and name, and there are official Python and Node SDKs (14 of 15).

ONES 55

No downloadable OpenAPI file was found. The reference is rendered pages, and the MCP docs list tool names and one-line descriptions without input schemas (0). llms.txt with sized indexes and a Markdown copy of every page (10). Endpoint and tool descriptions state what each does in one line, with version history per endpoint but little on when not to use one (10 of 20). Parameters are typed with defaults, limits (limit at most 100) and required marks (10 of 15). Each endpoint lists 200, 401, 403, 404 and 500 responses with schemas and examples (10 of 15). API version 2.0, a History table per endpoint and dated release notes (15). 0 + 10 + 10 + 10 + 10 + 15 = 55.

Plane 80

Every MCP tool is typed in the open repository, with action as a closed list. For the REST API the v2 docs say an OpenAPI document is served at /api/v2/schema/, but api.plane.so's robots.txt disallows every path, so we didn't read it, and the 8 October reading of that host is struck. v1's spec is off by default on self-hosted installs (20 of 25). llms.txt and a Markdown copy of every docs page (10). Each tool description lists its actions with required and optional parameters, a get_pql_reference tool explains the query language, server instructions cover epics, and each v2 endpoint page names its scopes and error codes. Guidance on when not to use a tool is thin (16 of 20). Enumerated values other than action are plain strings checked at call time, and optional parameters default to empty strings, per the repository's own conventions file (9 of 15). v2 pages carry cURL, Python and JavaScript examples and a full error code table, and the MCP docs have a troubleshooting table (13 of 15). API versions sit in the path, the MCP server has tagged releases with an upgrade guide, and the product changelog is dated. No developer changelog for the API was found (12 of 15).

ONES 62

Closed service under terms naming The Beautiful ONES Technology PTE. LTD. and Singapore law (15 of 30). The privacy policy of 7 January 2026 deletes business data 30 days after a service ends with no login for 365 days, and honours deletion requests within 30 days, but no DPA or subprocessor list is public (12 of 30). Endpoint version histories record changes, with no deprecation policy (5 of 20). The privacy policy names AWS, Oracle cloud and OpenAI and says data is transferred mostly to the US, China and Singapore, with no subprocessor list or regions (6 of 20). 15 + 12 + 5 + 6 = 38.

Plane 76

The MCP server and both SDKs are MIT and the Community Edition is AGPL-3.0. Plane Cloud and the Commercial Edition run under the Terms of Service of 9 April 2026 (26 of 30). The privacy policy, the DPA and the terms agree. Customer data is exportable for 30 days after termination and deleted within a further 60, raw logs are kept up to 12 months, breaches are notified within 72 hours, and customer data is not used to train general-purpose models (26 of 30). No deprecation policy with dates was found. The docs mark v1 webhooks, the SSE endpoint and the npm MCP package as deprecated without removal dates, and say API v1 remains available (8 of 20). The sub-processor list of 9 April 2026 names 21 companies with locations and promises 30 days' notice. Hosting is on AWS, with the region not stated on the pages read (17 of 20).

ONES 68

Latest dated release notes are 7.33.0 on 30 September 2026, 37 days before this check. The registry entry moved to 1.0.3 on 8 October with no release note behind it, so it doesn't set recency (20). Nine dated releases since 8 August, several adding Open API endpoints or MCP capabilities (7.23.0, 7.26.0, 7.27.0, 7.29.0) (20). Closed service with a public changelog and support by email, with no public issue tracker (8 of 15). Verified com.ones/ones namespace in the official MCP registry (15). One official SDK for apps, with package health not checked (5 of 10). 20 + 20 + 8 + 15 + 5 = 68.

Plane 80

Core release v1.4.3 was tagged on 28 October 2026 and the product changelog has an entry on 21 October. MCP server v0.3.5 (22 October) only updates certificate bundles and dependencies, so it doesn't set recency (30). In the 90 days from 3 August, six MCP server releases from 0.3.0 (14 August) to 0.3.5 (the last dependency-only, counted half), core v1.4.2 and v1.4.3, and product changelog entries about twice a month (20). The server repository had 38 open issues and pull requests on 8 October, most of the 30 newest with at least one reply, but several self-hosted bug reports from June and July 2026 open. Not re-read on 1 November because GitHub's pages refuse our reader (15 of 25). plane-sdk 0.3.2 (22 October, a certificate-bundle update) and @makeplane/plane-node-sdk 0.3.1 (22 September, per the 8 October check) are current. Plane's server isn't in the official MCP registry, searched on 1 November (10 of 15). Dependencies are pinned to recent versions of mcp and fastmcp and the repository has a test suite, but the public workflows only build the Docker image and publish to PyPI, per the 8 October check (5 of 10).
