# Sentry: the 360 agent-readiness check

Sentry scores 80 of 100 on Ora's agent-readiness scan, a B, read 9 November 2026. Of the five surfaces an agent acts on, Ora found 3: a public API, OAuth, a command line. WebMCP registered and two agent files that do not validate.

On 9 November 2026 the public site at sentry.io scored 80 of 100 on [Ora's](https://ora.ai/?utm_source=agentmcpdirectory.com&utm_medium=referral&utm_campaign=check) agent-readiness scan, a B, in Ora's Infrastructure category. Ora probes a site the way an agent would: it requests pages with the agents' own user agents, reads robots.txt, looks for the files agents read, and tries the API, MCP and payment surfaces. This check reads the act layer first, because that is what the directory records, then the door, what an agent can read, and whether the company is found and recommended. Ora's one-line summary: Sentry offers strong discovery and developer SDK coverage, but lacks a published OpenAPI specification for agents to integrate against.

## The score

| Layer | Asks | Points | Share |
| --- | --- | --- | --- |
| Usability | Can agents use it | 59.5 of 78 | 76% |
| Access | Can agents read it | 48 of 62 | 77% |
| Discovery | Can agents find and recommend it | 13 of 14 | 93% |
| Payments | Can agents pay | 0 of 0 | none apply |
| Total | Grade B | 80 of 100 | 80% |

## What an agent can do

The surfaces an agent acts on: an API it can find and call, an MCP server, an agent card, OAuth metadata, a command line. This is the layer the directory records, so it comes first.

In the directory, Sentry sign-in required, tools not seen, not counted; the connector run of 4 November 2026 is on [the entry page](https://agentmcpdirectory.com/directory/sentry-io/). Ora's MCP server check for the same domain reads partial; the two look for different things, the directory for a server that answers a handshake and lists tools, Ora for a server it can find from the site.

| Check | Result | Points | What Ora saw |
| --- | --- | --- | --- |

| Check | Result | Points | What Ora saw |

## Payments

The agent payment protocols Ora probes for. A site that sells nothing has nothing here, and Ora scores the layer out of zero when none applies.

## The fixes worth most points

Ora attaches an estimate to each failing or partial check: how many points the site would gain by passing it. These are the 5 with the largest estimates for Sentry, with what Ora observed. The wording of each fix is Ora's; [the 28 checks it runs on an MCP server](https://agentmcpdirectory.com/mcp-checks/) are listed with their layer and tier.

-   OpenAPI spec published: fail, 0 of 7, about 3.8 points to gain. Ora saw: No OpenAPI/Swagger specification found
-   JSON error responses: fail, 0 of 4, about 2.3 points to gain. Ora saw: API does not return JSON error responses (or no API detected)
-   GraphQL typed error model: fail, 0 of 3, about 1.7 points to gain. Ora saw: GraphQL introspection auth-gated and no typed graphql error model documentation found on GraphQL-tagged pages
-   ARD discovery: partial, 0 of 1, about 1.6 points to gain. Ora saw: /.well-known/ard.json exists but is not valid JSON
-   GraphQL versioning / deprecation policy: fail, 0 of 2, about 1.1 points to gain. Ora saw: GraphQL introspection auth-gated and no graphql versioning / deprecation policy documentation found on GraphQL-tagged pages

## Our read

Sentry has done the newer act-layer work and skipped the older: a WebMCP tool is registered in a script bundle, the MCP server at mcp.sentry.dev/mcp answers and requires authentication, it is discoverable at sentry.io/.well-known/mcp.json, OAuth authorization server metadata is on the main domain, @sentry/cli is on npm, SDKs are in four registries, and sentry.io serves an llms.txt and returns markdown on request. The missing piece is an OpenAPI specification, about 4 points, and two published files are broken: the ARD catalog at /.well-known/ard.json is not valid JSON, and the agent skills index has an empty skills array. Endpoints do not answer errors as JSON and the GraphQL introspection is gated. The home page is 15,918 characters at a 4 percent text ratio, just under the target, with two complete Organization blocks. An error-tracking company with two files that would fail its own checks is the sentence the editors could not resist.

## Test your own surfaces

The scan above is free and needs no account: enter a domain at [ora.ai](https://ora.ai/?utm_source=agentmcpdirectory.com&utm_medium=referral&utm_campaign=check) and read the same four layers for your own site. For an MCP server, Ora scans the server URL itself and runs 28 of its 132 public checks on it, which is why it is the check this directory recommends; [the reasons, the limits and the alternatives](https://agentmcpdirectory.com/test-your-mcp-server/) are on their own page. The command below runs the same audit from a terminal and exits with 1 under the score you set, so it can gate a deploy.

```bash
npx ax@0.10 audit https://example.com --min-score 70
