Ora's one-line summary: GM.com offers developer resource discoverability, but lacks an OpenAPI specification.
What an assistant meets at the door
Before an assistant can read, compare or buy, it has to get in. These rows are the door: whether the bot shield lets the main agents through, what robots.txt tells the search, training and user-triggered agents, and whether the home page has text without running JavaScript.
| Check | Result | What Ora saw |
|---|---|---|
| Not blocked by bot detection | Partial, 0 of 2 | Bot management challenged GPTBot, ClaudeBot, ChatGPT-User, PerplexityBot, Applebot-Extended. A challenge is an identity check that verified crawlers pass. |
| Agent crawler reachability | Partial, 0 of 2 | Bot management challenged ChatGPT-User, ClaudeBot, DeepSeekBot - a challenge is an identity check verified crawlers pass, so reachability is undetermined rather than blocked (ChatGPT-User: challenged). |
| robots.txt AI crawler policy | Did not apply, 0 of 2 | Cannot verify robots.txt permission for training and search crawlers: WAF/bot challenge (HTTP 403) |
| robots.txt agent-user policy | Did not apply, 0 of 2 | Cannot verify robots.txt permission for user-triggered agents: WAF/bot challenge (HTTP 403) |
| Content without JavaScript | Partial, 0 of 3 | Homepage blocked by WAF/security challenge - content not accessible to agents |
What it can read, and what it can do
The reading layer is what an assistant takes away from the pages: a text file written for it, markdown on request, structured data about the company, a sitemap. The act layer is whether it can do anything through a published interface rather than by clicking through the site.
| Check | Result | What Ora saw |
|---|---|---|
| llms.txt exists | Fail, 0 of 1 | No llms.txt found at /llms.txt or /.well-known/llms.txt. |
| llms.txt formatting | Fail, 0 of 2 | No llms.txt found to evaluate quality |
| Markdown agent docs | Fail, 0 of 1 | Missing markdown content negotiation. Homepage returned text/html when probed with Accept: text/markdown (expected text/markdown), and none of the well-known root paths (/llms.md, /auth.md, /agents.md, /developers.md). |
| Bot-UA markdown serving | Did not apply, 0 of 1 | Site is behind a WAF/bot wall - cannot probe bot-UA serving |
| JSON-LD structured data | Partial, 0 of 4 | Homepage blocked by WAF - cannot check structured data |
| Organization schema completeness | Partial, 0 of 2 | Homepage blocked by WAF - cannot check Organization schema |
| Sitemap exists | Fail, 0 of 2 | No sitemap found |
| Metadata completeness | Partial, 0 of 2 | Homepage blocked by WAF - cannot check metadata |
| Page token budget | Did not apply, 0 of 1 | Nothing sampled to measure |
| Check | Result | What Ora saw |
|---|---|---|
| MCP server / manifest | Fail, 0 of 6 | No MCP server or manifest found |
| MCP well-known discovery | Partial, 1 of 2 | MCP server at https://developer.gm.com/mcp - consider adding /.well-known/mcp for standard discovery |
| Public API with reachable endpoints | Pass, 7 of 7 | GraphQL endpoint at https://gm.com/graphql is reachable; introspection requires authentication (API key / OAuth), which is expected for agent access. Best-of-protocols score: 7/7. |
| Public API/docs linked from homepage | Partial, 0 of 3 | Homepage blocked by WAF - cannot check for docs links |
| OpenAPI spec published | Fail, 0 of 7 | No OpenAPI/Swagger specification found |
| Developer portal | Fail, 0 of 6 | No developer portal found |
| OAuth 2.0 support | Fail, 0 of 5 | No OAuth 2.0 or OpenID Connect support detected |
| Scoped permissions | Fail, 0 of 5 | No declared OAuth scopes, security schemes, or scoped-permission documentation found |
| Multi-language SDK packages | Fail, 0 of 3 | No SDK packages found across language ecosystems |
| CLI tool available | Fail, 0 of 3 | No CLI tool found |
| WebMCP support | Fail, 0 of 5 | No WebMCP support detected - no tool-attribute forms and no document.modelContext / navigator.modelContext usage found |
| Check | Result | What Ora saw |
|---|---|---|
| Wikipedia / Wikidata entity presence | Partial, 2 of 4 | Wikipedia "GM Ecotec engine" verified - create a Wikidata item with P856 (official website) = gm.com to complete knowledge graph coverage |
| Brand name discoverability | Pass, 3 of 3 | gm.com appears at position #1 in a clean brand-name search for "gm" (1 total match) |
| Category share of voice | Did not apply, 0 of 6 | Category share of voice is in beta. It measures whether agents surface you for capability and use-case searches (not just your name). |
| Developer resource discoverability | Pass, 3 of 3 | Agent discovered 1 developer-resource type by name (developer portal) across 1 page |

Three fixes to hand to the web team
Ora estimates how many points each open check would return. These are the largest on this read, in Ora's words where it gave them, so a leader can hand the list over without translating it.
- MCP server / manifest, worth about 4.6 points by Ora's estimate: No MCP server or manifest found.
- OpenAPI spec published, worth about 4.6 points by Ora's estimate: No OpenAPI/Swagger specification found.
- Developer portal, worth about 3.9 points by Ora's estimate: No developer portal found.
Our read
General Motors challenges the agents and leaves them one endpoint. Bot management challenged GPTBot, ClaudeBot, ChatGPT-User, PerplexityBot and Applebot-Extended, robots.txt answered with a 403 challenge and the home page came back as a security page, so the door, content, policy, structured-data and metadata rows are unverified rather than failed, and the Access layer reads 1 of 51. There is no sitemap and no llms.txt. What Ora could reach is a GraphQL endpoint at gm.com/graphql with introspection gated behind authentication; it found no developer portal, no OpenAPI specification, and neither an MCP server nor OAuth discovery, so the Usability layer reads 11 of 58. The Discovery layer is the one in order, 8 of 10: gm.com sits first in a clean search for gm, and Wikipedia confirms the company, though the article matched is the one for the Ecotec engine and no Wikidata item points at the domain. An F built on a 403 is a policy, and the first row to change is the one that issues it.
