## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Endpoint Security**: 80/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 59/100
  - AI-judged instruction clarity (fair).
  - Tool/resource definitions use about 521 tokens (~104/item across 5 items; 5 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 71/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 13% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 20/100
  - Spec-recency check failed: implements MCP spec 2024-11-05; the latest is 2026-07-28.

## Install

### How do I install the MCP OAuth client-interop conformance server?

## MCP tools (5)

### `conformance_check` (~94 tokens)

MCP OAuth conformance check

run one full client x IdP-shape conformance matrix (the POST /check operation; x402 $0.01 per check unless your account has an active Solo subscription/trial, metered exactly as REST)

Input parameters:

- `apply_shims` (boolean)
- `clients` (array)
- `full_matrix` (boolean)
- `idp_shape` (string)
- `server_config` (object)

### `claim_trial` (~182 tokens)

Claim the free trial month

claim the one-time free first Solo month for your first server (the POST /trial/claim operation; Bearer token required; EIP-191 proof required — first call the REST POST /trial/challenge, sign the returned message with your registered wallet, then pass nonce + signature here, exactly as REST)

Input parameters:

- `apply_shims` (boolean)
- `check` (object)
- `clients` (array)
- `full_matrix` (boolean)
- `idp_shape` (string)
- `nonce` (string): single-use nonce from POST /trial/challenge
- `server_config` (object)
- `server_name` (string)

- `wallet` (string): optional; must equal the account's registered payer wallet

### `subscribe_solo` (~191 tokens)

Subscribe (Solo or Fleet)

activate/extend a subscription via x402 X-PAYMENT header (the POST /subscribe operation; Bearer token required): Solo $9/mo per server by default, or Fleet $29/mo for up to 10 servers with tier=fleet (WO-F-P22-17/RT-20 — the tier parameter is advertised here exactly as in the REST OpenAPI). The embedded check shape (server_config / idp_shape / full_matrix / clients / apply_shims / check) is accepted and stored for hourly re-runs, exactly as REST.

Input parameters:

- `apply_shims` (boolean)
- `check` (object)
- `clients` (array)
- `full_matrix` (boolean)
- `idp_shape` (string)
- `server_config` (object)
- `server_name` (string)
- `servers` (array)
- `tier` (string)

### `run_history` (~29 tokens)

Run history

list only your own account's past matrix runs (the GET /history operation; Bearer token required)

### `subscription_status` (~25 tokens)

Subscription status

your account's subscription status (the GET /subscription operation; Bearer token required)
