- name: ai.openarx/openarx
- version: 0.3.2
- connection class: R2 (oauth_consent_once)
- trust: 63/100 flags: unreachable
- quality: 83/100 (good)

**An agent can connect after a one-time OAuth consent by a human.** Remote endpoint behind OAuth 2. Tokens stay with the agent; the registry only exposes the authorization metadata.

## Connection (mcpServers)

```json
{
  "mcpServers": {
    "openarx": {
      "type": "http",
      "url": "https://mcp.openarx.ai/researcher/mcp"
    }

## Trust

- hygiene: 100
- liveness: 0
- freshness: 85
- provenance: 85
- drivers: +repository +dns-namespace +website -unreachable(5 failures) ~updated-83d-ago
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 83/100 (good)

### protocol: n/a (weight 25)

- n/a `protocol.modern`, `protocol.stateless`, `protocol.transport`, `protocol.list_ttl`: no remote answered a protocol handshake (not probed yet, unreachable, or local-only)

### authorization: 83 (weight 15)

- pass `auth.prm`: Protected Resource Metadata (RFC 9728) published
- pass `auth.as_metadata`: authorization server metadata reachable
- warn `auth.cimd`: only Dynamic Client Registration, deprecated in 2026-07-28 in favour of CIMD
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: n/a (weight 30)

- n/a `tools.descriptions`, `tools.description_length`, `tools.schemas`, `tools.annotations`, `tools.directory_hints`, `tools.token_cost`, `tools.api_dump`: tool list unknown (behind auth, not probed, or empty)

### stability: n/a (weight 15)

- n/a `stability.changes`, `stability.rug_pull`: tool list unknown

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: unknown
- badge: [![protogrid quality](https://protogrid.dev/badge/ai.openarx/openarx.svg)](https://protogrid.dev/servers/ai.openarx/openarx)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.
