1 human and 5 agent dimensions measured from the pages checked; remaining dimensions are not scored.
## Scores
| Measure | Score |
| --- | --- |
| Humans | 80/100 (1/4 dimensions) |
| Agents | 60/100 (5/6 dimensions) |
| Composite | 70/100 |

The human score is the mean of the measured human dimensions, the agent score the mean of the measured agent dimensions, and the Door Gap the difference between them.
## What the machine actually did
The scanner recorded successful observations for 10 of 15 checks, but could not find an MCP manifest at the standard paths checked. It came up empty on 4 other checks too. 1 check could not be measured; see the report limitations.
- ok      reach the site at all
- ok      find out whether machines are welcome
- ok      ask whether the door opens for requests carrying the AI crawlers' names
- ok      read the site's own guide for language models
- ok      find out what pages exist
- missing find an MCP manifest at the standard paths checked
- missing find an agent plugin manifest
- missing find out whether verified agents are recognised
- ok      read the homepage as data rather than as a page
- missing find a machine readable API spec
- missing read the developer documentation
- ok      read the prices without running JavaScript
- ok      find a comparison page worth citing
- ok      walk the way a visitor would, to a signup form or a product
- ok      read this page during the extended scan

## Top issues
1. **No OpenAPI specification was identified at the 6 standard paths checked.** (programmatic_onboarding)
   - Evidence: No OpenAPI spec at the 6 standard paths checked (/openapi.json, /openapi.yaml, /swagger.json, /api/openapi.json, /api-docs, /.well-known/openapi.json). Documentation links found: https://www.mongodb.com/docs/manual/reference/geojson/, https://www.mongodb.com/docs, https://www.mongodb.com/docs/generative-ai-faq
   - Evidence: Checked directly: /openapi.json, /openapi.yaml, /swagger.json, /api/openapi.json, /api-docs, /.well-known/openapi.json.
   - Evidence: Checked URL: https://www.mongodb.com
   - Fix: Publish the API's OpenAPI document at /openapi.json or /.well-known/openapi.json and link it from the docs.

## Files generated from this scan
- **Machine interfaces: where you stand** at `notes`, 10 minutes, no developer needed. Verify: The next scan finds the interface you published answering at its well-known path, and that check passes.
- **Organization structured data** at `homepage`, 15 minutes, developer. Verify: The next scan reads Organization and WebSite nodes in the homepage JSON-LD and the structured data check passes.
Each file is written from what this scan found on the site. The content is in the JSON once the evidence is opened: https://www.seconddoor.io/api/reports/mongodb-htueg8
## The agent door
- **machine_discoverability** 100/100. No restriction on the tested crawler names was found in robots.txt. On its first visit, our browser read the homepage. No user agent rule refused the tested retrieval crawler names.
- **programmatic_onboarding** 20/100. No API interface was identified through the discovery paths and homepage links checked.
- **pricing_legibility** 93/100. 218 prices are readable without JavaScript, with no tier sent to sales. The plans are published as Offer structured data too.
- **agent_aware_instrumentation** 18/100. No MCP manifest was identified at the discovery paths checked. Pricing.md publishes prices in a form an agent can read directly.
- **machine_fetchable_trust** not measured. Not measured: robots.txt did not permit our scanner to read the required page.
- **commercial_rails** 70/100. Prices are published in raw HTML. A self-serve signup entry was observed from the homepage. Pricing.md is machine readable. The plans are published as Offer structured data.
## The human door
- **steps_to_first_value** 80/100. A signup form was reached in 2 steps from the homepage.
- **required_fields** not measured. Not measured: our scanner could not identify the required evidence on the pages checked.
- **verification_walls** not measured. Not measured: this read-only scan did not submit the form or perform the action needed to test this behavior.
- **error_recovery** not measured. Not measured: this read-only scan did not submit the form or perform the action needed to test this behavior.
