Cursor pagination with limit 1 to 50, status and project filters on tasks, and message parts that admins can trim, though results of tool calls may be truncated without a size control (18 of 20). One error envelope with type, message and requestId, 402 and 403 that name the plan or scope at fault, and a recovery table for each direct-tool failure (18 of 20). Idempotency-Key required on every write that starts work, a 24-hour replay, cancel documented as safe to repeat, and an unknown status that tells the agent to inspect before retrying; deletes need confirmation, but readOnlyHint and destructiveHint annotations were not confirmed since tools/list was not read (16 of 20). Few required parameters, but no official SDK in any language (7 of 15). 23 + 18 + 18 + 16 + 7 = 82.\n- Onshape (46): Document and element endpoints take ids and the list endpoints take limit and offset, with no field selection documented in what we read; the MCP server's tool count is unknown (12 of 25). Pagination and filters on document lists, and revisions page (a paging loop was fixed in rel-1.219) (14 of 20). HTTP codes with 401, 402 and 429 meanings; the error body shape was on the unread response codes page (10 of 20). No idempotency keys; POSTs create microversions on every edit; no readOnlyHint or destructiveHint published for the MCP tools (2 of 20). Every API key request needs a Date header, a nonce and an HMAC-SHA256 signature, and 307 redirects need a new signature; official Go and TypeScript clients handle it (8 of 15). 12 + 14 + 10 + 2 + 8 = 46.\n\n### Reliability: Onshape +25\n\n- Adam (35): Read with the hosted lines. status.adam.new exists and is linked from the docs, but it loads its components and history by script and nothing readable was served, so the page counts for half (10 of 20) and the incident record is unread (5). Rate limits are documented as two refilling buckets reported in RateLimit, RateLimit-Policy and X-RateLimit headers, with no numeric quota published (5 of 15). 429 carries Retry-After, and Idempotency-Key is required on task creation, messages and tool calls and replayed for 24 hours (15). No SLA found (0). The MCP server and the REST API are labelled beta, with breaking changes allowed (0 of 10). 10 + 5 + 5 + 15 + 0 + 0 = 35.\n- Onshape (60): Read with the hosted lines on cad.onshape.com. Atlassian Statuspage at status.onshape.com with regional CAD service components and history feeds (20). The feed holds 18 incidents from 15 August to 30 October 2026, all degraded performance, delayed imports and exports or partial signup blocks, the longest 2 hours 42 minutes of export degradation on 15 September and imports, exports and notifications not working for 1 hour 42 minutes on 11 September; no full outage of the CAD service (18 of 30). Annual API call quotas are published per plan with numbers, while per-endpoint rate limits are said to vary by endpoint with no figure (8 of 15). 429 is documented without a header or backoff timing, 402 marks a spent quota, and no idempotency guidance was found (6 of 15). The terms promise commercially reasonable efforts and no SLA (0). The REST API is generally available; the FeatureScript MCP Server is an early-access Labs feature (8 of 10). 20 + 18 + 8 + 6 + 0 + 8 = 60.\n\n### Maintenance \u0026 community: Onshape +24\n\n- Adam (55): Read for a closed service. The changelog's newest entry is 10 September 2026, 54 days before this check (20). Entries dated 7, 10, 11 and 25 August and 4 to 10 September 2026, more than three in 90 days (20). A public changelog, hello@adam.new, a Discord and the CADAM repository with 26 open issues, which were not read for replies (10 of 15). The manifest follows the registry schema but new.adam/adam is not in the official MCP registry, and there is no official SDK (0 of 15). CADAM was pushed on 15 October 2026 and the service itself has no package to judge (5 of 10). 20 + 20 + 10 + 0 + 5 = 55.\n- Onshape (79): Read for a closed service. API release notes rel-1.223 dated 30 October 2026 (30). Six dated releases from 17 July to 30 October, three weeks apart (20). A public changelog, forum.onshape.com and api-support@onshape.com; response times were not tested (12 of 15). No Onshape-owned server in the official MCP registry, where the only match is io.github.gpambrozio/onshape; the official Go client was pushed on 31 October 2026 and the TypeScript clients in June and September 2025 (12 of 15). The Go client is generated and its CI was not read; the multi-language onshape-clients repository is archived (5 of 10). 30 + 20 + 12 + 12 + 5 = 79.\n\n### Schema \u0026 documentation: Adam +18\n\n- Adam (81): Public OpenAPI 3.1 for the REST API (adam.new/openapi.json and api.adam.new/openapi.json), a site spec for OAuth and MCP endpoints, and an MCP manifest. MCP tool schemas were not read, since tools/list needs a sign-in, though adam_list_task_tools is documented to return input schemas (20 of 25). llms.txt, a docs index at docs.adam.new/llms.txt, Markdown for every page on request through the Accept header, and a starter SKILL.md (10). The direct-tools page gives each MCP tool a purpose and its scopes, and OpenAPI descriptions state conditional requirements such as cron or runAt, but no tool definition says when not to use it (12 of 20). Enums for task status, limit 1 to 50, required fields and multipart file fields are typed; the component schemas past the first 100,000 characters were not read (11 of 15). Every operation documents 400 to 500 responses with one error envelope, and the API introduction carries curl and JSON examples (13 of 15). Versioned /v1 paths, Deprecation and Sunset headers with 90 days' notice, and a dated changelog, though its newest entry is 10 September 2026 (15). 20 + 10 + 12 + 11 + 13 + 15 = 81.\n- Onshape (63): An OpenAPI document backs the Glassworks API Explorer and the generated Go and TypeScript clients, but cad.onshape.com/robots.txt closes the explorer and the document to readers, so the contract was seen only through the clients (18 of 25). No llms.txt and no Markdown twin of the docs (0). Guides per area state what each API does and the API intro explains documents, workspaces, versions and elements; the MCP server's tools are not listed anywhere public (12 of 20). The Go client's breaking-change list shows typed models with BTType mandatory; enums and constraints were not read in the spec itself (10 of 15). Guides carry examples; the response codes page linked from the docs answered 404 and the API limits page gives 429 and 402 meanings (8 of 15). Numbered API versions (v17), dated release notes every three weeks, deprecations marked and an x-deprecated header (15). 18 + 0 + 12 + 10 + 8 + 15 = 63.\n\n### Transparency \u0026 trust: Adam +12\n\n- Adam (72): Closed service under terms of 5 June 2026 that name Adam AI Labs, Inc. but state no governing law, refund or notice terms beyond email; CADAM is GPL-3.0 (13 of 30).

Deprecations are marked in dated release notes and flagged with an x-deprecated header, but no notice period is stated (12 of 20). Subprocessors are named and the status page lists hosting regions by continent; no formal data location statement was read (14 of 20). 15 + 12 + 12 + 14 = 53.\n\n### Security \u0026 auth: Adam +11\n\n- Adam (74): OAuth 2.1 authorisation code with PKCE S256, automatic client registration, RFC 8707 resource indicators, refresh tokens, a revocation endpoint and 11 scopes, or a personal key minted for one workspace with chosen scopes and shown once; bearer header only, no query-string option (30).

The MCP server and API are beta, numeric rate limits and plan prices are not published, and native CAD edits need a connected desktop application.\n\n**Onshape.** Scoped API keys, OAuth 2.0 and versioned release notes every three weeks give an agent a stable REST surface over documents, parts, assemblies and drawings, and the Labs MCP server writes FeatureScript. Each request needs an HMAC signature and nonce, annual call quotas end in 402, per-endpoint limits are unpublished, and robots.txt closes the OpenAPI explorer's host to readers.\n\n## Before you call either\n\n### Adam\n\n1. Call adam_get_context first and check the scopes; client-driven tool calls need `tasks:read`, `tasks:write` and `tools:execute`, which an admin may have blocked\n2. Send a fresh UUID as Idempotency-Key on every task, message and tool call, reuse it on a retry, and on status unknown inspect the task before retrying with a new key\n3. Poll adam_get_tool_call for queued or running calls; creating an external task starts no inference, but executing tools spends the workspace's usage\n4. Treat 402 as a plan or usage limit for the person to resolve, and on 429 wait for Retry-After\n5. Expect only Adam-stored models to export without a desktop; ask the person to connect Onshape, Fusion or SOLIDWORKS before native edits\n\n### Onshape\n\n1. Sign every API key request with a Date header within 5 minutes, a unique 16-character On-Nonce and `Authorization: On \u003cAccessKey\u003e:HmacSHA256:\u003csignature\u003e`; prefer OAuth 2.0 bearer tokens and refresh on 401\n2. Count calls against the plan's annual quota (2,500 per user on Free) and treat 402 as quota exhausted, not a payment request; 4xx and 5xx responses do not count\n3. Put the API version in the path (api/v17) and pin it, since unversioned calls use v0 and unknown versions fall back to the newest\n4. On 429 back off and reduce redundant calls; no Retry-After or numeric limit is published, and imports and exports were the component most often delayed in the 90-day record\n5. For FeatureScript work, subscribe to the FeatureScript MCP Server in the App Store first, then `claude mcp add --transport http onshape https://fs-mcp.labs.onshape.app/mcp` and authorise in the browser; use `/mcp` to re-authenticate\n\n## Questions\n\n### Which is better for AI agents, Adam or Onshape?\n\nAdam scores 59.4 (C) on agent readiness against Onshape's 55.7 (C), and leads in 4 of 7 scored categories. Onshape leads on reliability, payments \u0026 pricing and maintenance \u0026 community.\n\n### Do Adam and Onshape need an API key?\n\nBoth take an API key or an OAuth sign-in.\n\n### Can an agent call Adam and Onshape without installing anything?\n\nYes. Adam has a hosted endpoint at https://adam.new/mcp and Onshape at https://fs-mcp.labs.onshape.app/mcp.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/adam-cad-vs-onshape.json, and with the fewest tokens: https://www.anchorterminal.com/compare/adam-cad-vs-onshape.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"adam-cad\", \"b\": \"onshape\"}`.
