Endpoint report / Metadata only
Linear MCP
A dated endpoint inspection. Metadata and any separately recorded tool call have their own evidence, scope and limitations.
What this establishes
The anonymous initialization request returned HTTP 401. No tool catalog was observed; authenticated behavior remains untested. This is an access boundary, not a quality failure.
Account access and a scoped test identity are needed for further evaluation.

Recorded checks
These checks cover the metadata inspection. They are separate from the tool-call result above, when present.
protocol-negotiation
Authentication is required. This anonymous inspection did not test protected metadata or OAuth login.
initialized-notification
Initialization notification was not sent.
tool-catalog
The tool catalog was not inspected.
tool-metadata-shape
Basic metadata shape was not inspected; this is not complete JSON Schema validation.
oauth-login
OAuth discovery, login, token refresh and authenticated access are outside this anonymous inspection.

What this report does not establish
These observations do not establish general task success, security, OAuth behavior or ChatGPT and Claude compatibility. Read the limits of each recorded test.
- Metadata-only anonymous inspection. No tools/call, OAuth flow, API model calls, host UI or publication review was executed. No global quality or safety score is produced.
- Annotations are server declarations, not verified behavior. Metadata success does not establish task success, security, usefulness or ChatGPT/Claude compatibility.
- Only active exact HTTPS endpoints in the reviewed source registry are accepted. Redirects, supplied credentials, arbitrary endpoints and OAuth URL fetching are disabled. DNS/TLS use the local runtime: this is not a hardened multi-tenant SSRF sandbox and must not be exposed as a public scanner.
- Session identifiers are used only in memory. Request/response headers, raw error messages, raw descriptions and schemas are excluded from artifacts. Tool names and aggregate metadata remain untrusted server input.
- Only the recorded protocol versions and bounded catalog prefix are supported. Reaching a bound or lacking access means unknown, not a failed server or a passing full audit.
