Onshape
by PTC HTTP API in CAD, engineering & fabrication

PTC Inc. · onshape.com · status page · who's behind it
Onshape is PTC's cloud CAD platform. Its REST API reads and changes documents, Part Studios, assemblies and drawings with API keys or OAuth 2.0, and the FeatureScript MCP Server in Onshape Labs lets an assistant write FeatureScript into a document.
Best for Agents that read or change existing cloud CAD documents, run configurations, pull BOMs and drawings, or write FeatureScript for a team already on Onshape.
Viewed under 500 times in the last 30 days · Claim it, free, to see who finds it
Is this your product? Claim it to see how agents find it: lookups through the API, MCP and letme, the comparisons it's in, and what people search for in CAD. Free, and it never changes the grade. Or verify it, or log in if it's already claimed.
Assessment. 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 Each request needs an HMAC signature and nonce, annual call quotas end in 402, per-endpoint limits are unpublished, and robots.txt closes the OpenAPI explorer's host to readers.

From our research 8 facts checked against the vendor's pages
- Surface listed
- The REST API read from onshape-public.github.io (API intro, OAuth2, API keys, API limits, changelog, help), the go-client README, the FeatureScript MCP Server blog post and tech tip, the Labs page, pricing, terms, data disclosures, the security page, status.onshape.com and the MCP registry on 3 November 2026. cad.onshape.com and ptc.com were not fetched because their robots.txt disallow it. No account was made and no call was signed
- Where it runs
- AWS, with CAD service components for North America (us-west-2), Western Europe, Southeast Asia, Australia and Northeast Asia, and Onshape Government on AWS GovCloud. Enterprise accounts use their own subdomain
- API shape
- URLs follow {base}/{endpoint}/d/{documentId}/{w|v|m}/{id}/e/{elementId}; POST always targets a workspace. Guides cover documents, Part Studios, assemblies, drawings, configurations, materials, metadata, import and export, FeatureScript, release management and response codes
- FeatureScript MCP Server
- Streamable HTTP at fs-mcp.labs.onshape.app/mcp, early access through Onshape Labs, subscribed to in the App Store. The assistant writes FeatureScript into a Feature Studio, checks errors, revises and inspects the geometry; an organisation can route it through the company API allocation. No tool list is published
- Clients
- go-client (MIT, pushed 31 October 2026, generated from the API with breaking changes listed), onshape-ts-client and onshape-ts-drawing-client; the onshape-clients multi-language repository is archived since 2023
- Plans and quotas
- Free $0 (public documents), Standard $1,500 and Professional $2,500 per user per year, Enterprise by quote. API calls per year are 2,500 per user (Free, Standard, EDU Student), 5,000 (Professional) and 10,000 per full user (Enterprise), pro-rated when seats change
- Security
- SOC 2 Type 2 audited annually (report under NDA), AES-256 at rest, TLS 1.2 in transit with HSTS, paid third-party researcher testing, reports to security@onshape.com. No security.txt (404)
- Legal entity
- PTC Inc., acting through its Onshape business unit, per the terms of 15 July 2020. Onshape was founded in 2012 and acquired by PTC in November 2019
Facts verified 3 November 2026 from vendor docs, repositories and package registries. JSON · Markdown
Strengths
- API keys scoped to permissions and revocable, and OAuth 2.0 with 60-minute access tokens and refresh tokens tied to the user's grant
- Versioned API (v17) with dated release notes every three weeks, deprecations marked and an x-deprecated response header
- Official FeatureScript MCP Server over Streamable HTTP, added to Claude Code with one command after an App Store subscription
- Statuspage with regional components and a 90-day record of short degradations, none a full outage
- Free plan for non-commercial use and a Professional trial of up to six months with no card
Weaknesses
- Every API key request must be signed with HMAC-SHA256 over the method, nonce, date, content type, path and query, and 307 redirects need a fresh signature
- Annual API call quotas (2,500 per user on Free and Standard) answer 402 when spent; per-endpoint rate limits are unpublished and 429 carries no documented header
- The Glassworks explorer and OpenAPI document are on cad.onshape.com, which robots.txt closes, and no llms.txt exists
- The MCP server is an early-access Labs feature with no public tool list, and AI agents are listed as coming soon
- The API agreement that governs programmatic use is on the developer portal and was not read; the privacy policy is PTC's
Before you call it notes for agents
- Sign every API key request with a Date header within 5 minutes, a unique 16-character On-Nonce and
Authorization: On <AccessKey>:HmacSHA256:<signature>; prefer OAuth 2.0 bearer tokens and refresh on 401 - 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
- 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
- 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
- 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/mcpand authorise in the browser; use/mcpto re-authenticate

Terms and privacy, as read
Terms of service gives no date, states 5 of 7, 5 to know
TL;DR Gives no date. States 5 of the 7 things a reader expects, and we didn't find how changes are announced. To know before relying on it, limits on automated access, limits on benchmarking, changes without notice, cut-off without notice or for any reason and arbitration or a class action waiver.
Restricts automated accesscosts points
Use any robot, spider, scraper or other automated means to access the Service, or use any data mining, data gathering or extraction method;
A rule against bots, scrapers or automated means can cover an agent, depending on how the vendor reads it.
Restricts benchmarking or competitive usecosts points
Analyze the Service, Software or Documentation for purposes competitive to Onshape, or access or otherwise use the Service, Software or Documentation in order to build a similar or competitive service offering;
A clause against publishing test results or using the service to build something that competes.
Says the terms or the service can change without noticecosts points
We reserve the right in our sole and absolute discretion to make changes from time to time and without notice in how we offer and operate our service.
A customer may not hear about a change before it applies.
Says access can be ended without notice or for any reason
Onshape shall be entitled to suspend, terminate, or limit your access to the Service at any time, with or without notice, if you breach any term of this Agreement, or if you facilitate or encourage any violation of this Agreement.
The vendor can suspend or close an account without warning, which would stop an agent mid-task.
Requires arbitration or waives class actions
THIS AGREEMENT INCLUDES A CLASS ACTION WAIVER AND REQUIRES BINDING ARBITRATION ON AN INDIVIDUAL BASIS TO RESOLVE DISPUTES, RATHER THAN JURY TRIALS.
Disputes go to an arbitrator, or a customer gives up joining a class action or a jury trial.
Gives the date it was last updated
Not found in the text.
Without a date nobody can tell which version they agreed to.
Names the governing law or courts The law of the Commonwealth of Massachusetts
Governing Law: This Agreement and any action related thereto will be governed and interpreted by and under the laws of the Commonwealth of Massachusetts, consistent with the Federal Arbitration Act, without giving effect to any principles that provide for the application of the law of another jurisdiction.

States a limit on its liability Capped at the fees paid in the 12 months before the claim
THE COLLECTIVE AND AGGREGATE LIABILITY OF APPLICATION DEVELOPER AND ONSHAPE TO YOU FOR ALL CLAIMS ARISING FROM OR RELATED TO THE APPLICATION IS LIMITED TO THE GREATER OF: (A) THE AMOUNT OF FEES ACTUALLY RECEIVED BY SUCH PARTY DURING THE LAST 12 MONTHS FROM YOUR PURCHASE OF SUCH APPLICATION;
Says the most the vendor would owe if the service causes a loss.
Says how the agreement or account can be ended
Suspension of Service: Your access to, and use of, the Service may be suspended temporarily for the duration of any scheduled maintenance or unscheduled downtime or unavailability of any portion, or all, of the Service for any reason, including as a result of power outages, system, or Internet failures or other interr…
Says when the vendor can cut off access and what notice it gives.
Says how changes to the terms are announced
Not found in the text.
Says whether a customer hears about a change before it binds them.
Lists what users may not do
IF YOU DO NOT AGREE TO THE FOREGOING, YOU MAY NOT ACCESS OR USE THE SOFTWARE.
The acceptable-use rules an agent acting for a user has to stay inside.
Refers to a service level or uptime commitment
In addition, we continually test various aspects of the Service, including Onshape’s website, user interfaces, service levels, plans, promotional features, delivery and pricing.
Says whether availability is promised and where the promise is written.
Access through anything other than an unmodified Onshape web or mobile client is also subject to Onshape's separate API Agreement, shown at the developer portal.
IF YOU ACCESS THE SERVICE THROUGH ANY MEANS OTHER THAN AN UNMODIFIED ONSHAPE MOBILE OR WEB CLIENT, THEN IN ADDITION TO THIS AGREEMENT YOU ALSO ARE SUBJECT TO THE TERMS AND CONDITIONS OF ONSHAPE’S API AGREEMENT (AS AMENDED FROM TIME TO TIME).

A reading by a fixed set of rules, each answered with the vendor's own sentence. It isn't legal advice, a rule can miss a clause or misread one, and the document itself is what binds. How it's read and scored.
PTC Inc., acting through its Onshape business unit, is named in the Onshape Product Terms of Use effective 15 July 2020, under Massachusetts law.
Section 4(b)(ix) of the terms forbids any robot, spider, scraper or other automated means to access the Service, and section 1 puts API use under a separate API agreement on the developer portal, which was not read. Recorded as facts.
www.onshape.com/robots.txt disallows many marketing paths (enterprise, landing pages, the free product pages); the legal, pricing, blog and tech-tip pages read are not among them. cad.onshape.com/robots.txt disallows everything except /help and /FsDoc, and www.ptc.com/robots.txt answered 403, so the privacy policy at the URL above was not read.
www.onshape.com/.well-known/security.txt answered 404.
The MCP endpoint is on labs.onshape.app, an Onshape domain; the API is on cad.onshape.com.

Live data comes from our pollers, trackers and scrapers and doesn't change the score until a benchmark run. What we watch · /api/v1/live/onshape.json
Notable
- The REST API lives at https://cad.onshape.com/api with a version in the path (api/v17 since rel-1.220 of 28 August 2026); calls without a version use v0, and an unrecognised version falls back to the newest source
- cad.onshape.com/robots.txt disallows every path except /help and /FsDoc, so the Glassworks API Explorer and the OpenAPI document it serves were not read; the generated Go client (v1.206, BTType mandatory) and TypeScript client stand in for it source
- Annual API call quotas by plan (2,500 to 10,000 per user) with 402 when spent, and per-endpoint rate limits that "vary by endpoint" with 429 and no numbers or headers source
- The FeatureScript MCP Server launched through Onshape Labs, an early-access program, is subscribed to in the App Store and added with
claude mcp add --transport http onshape https://fs-mcp.labs.onshape.app/mcp; the Labs page lists AI agents and automation as coming soon source - Dated API release notes every three weeks (rel-1.218 of 17 July to rel-1.223 of 30 October 2026), deprecations marked in the notes and an x-deprecated header on calls to deprecated endpoints source
- Atlassian Statuspage with 18 incidents between 15 August and 30 October 2026, all degraded performance or delayed imports and exports, the longest 2 hours 42 minutes source
- The terms of 15 July 2020 name PTC Inc. acting through its Onshape business unit, forbid robots, spiders and scrapers, and put API use under a separate API agreement on the developer portal, which was not read source
- The official MCP registry holds only a third-party server, io.github.gpambrozio/onshape 0.3.0 of 28 October 2026 source

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).

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).

Fix list 19 items, the biggest gain first
Everything this grade says the listing lacks, from the reasons above, the checklist, the provenance checks, the deductions, what we couldn't check and what the review panel asked for, with the steps, ready to paste into a coding agent working on Onshape. A fix counts at the next check, once it's public.
You're lucky. As part of the beta, your first month is free.
What we couldn't check
- unchecked: the OpenAPI document and Glassworks API Explorer on cad.onshape.com, whose robots.txt disallows every path except /help and /FsDoc; the contract was read through the generated Go and TypeScript clients
- unchecked: the Onshape API agreement on the developer portal, which the terms say governs API use
- unchecked: the privacy policy, which has moved to ptc.com; www.ptc.com/robots.txt answered 403
- unchecked: the FeatureScript MCP Server's tool list, annotations and plan requirements, and its App Store listing; appstore.onshape.com answered a bare 301 to robots.txt
- unchecked: whether the Free plan asks for a card at sign-up, and the price of additional API calls
- firstReleased is left empty. Wikipedia dates the company to 2012 and the PTC purchase to November 2019 for $470 million, but no first-hand page for the API's first release was read
- Judgement call on slug and name. Kept as onshape, the audit's slug; the vendor is PTC and the listing name is Onshape, the product's own name

Tell us where it is
We read it once now and again every week. If the link is missing two weeks in a row the listing says so, and a later check puts it back.
Agents send the same to POST /api/v1/verify as {"slug": "onshape", "url": "…"}, or call the verify_listing tool at /mcp. Ten checks an hour from one address. What we check. To announce the listing, get sharing assets for social media.
Share this listing
For the vendorGet sharing assets for social media. Two images say Onshape is listed on Anchor Terminal, with your logo and this page's address, one for a dark feed and one for a light one. They carry no grade or score, so they stay right when a score moves.
Link the post to https://www.anchorterminal.com/tools/onshape. The logo is the one on this listing. If it's wrong or out of date, send us the right one.
