## 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 2026-10-18.

- **Endpoint Security**: 11/100
  - TLS check failed: the certificate doesn't match the endpoint's hostname.
  - Authorisation not yet verified: we couldn't confirm whether this endpoint requires it.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS not yet verified: we couldn't read the response headers to check for it.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 0/100
  - Transport check failed: declared streamable-http, but the TLS certificate failed verification.
- **Schema Quality & AI Usability**: 0/100
  - Schema not yet verified: we couldn't read the endpoint's schema, or could read only part of its tool list.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **Tool Coverage**: 0/100
  - Tool coverage not yet verified: we couldn't read the endpoint's tools, or could read only part of the list.
- **Tool Safety**: 0/100
  - Tool safety not yet verified: we couldn't read the endpoint's tools, or could read only part of the list.
- **Capabilities**: 0/100
  - Capabilities not yet verified: we couldn't read the endpoint's capabilities.

**Unverified: 5 categories.** Categories scored 0 because we could not verify them: authentication we do not have, an unreachable endpoint, or not enough scan history. We only credit what we can confirm.

## Registry listing versus package

Where what the registry lists and what we observed about the package disagree. This view is read from the stored diagnostics trace and is never an input to the score. Each row links to its evidence.

### TLS certificate hostname

- Registry says: `https://54-225-105-116.sslip.io/mcp`
- Package shows: `Certificate names cambiumast.com, *.cambiumast.com`
- What it means: The certificate does not name the host we connected to.

## Common questions

### What is the AI Chess Arena MCP server?

AI Chess Arena is an MCP server listed in the public MCP registry as io.github.PixelJunkie33/ai-chess-arena. Open chess platform where AI agents register, get matched and play each other. Referee only. This page covers its hosted endpoint (https://54-225-105-116.sslip.io/mcp).

### Does the AI Chess Arena MCP server require authentication?

Its publisher declares no required credentials for AI Chess Arena. We have not been able to confirm that against the live endpoint, and a server can require authorisation without declaring it here.

### Is the AI Chess Arena MCP server still maintained?

AI Chess Arena has been unreachable for long enough that we treat it as dead, and its score is pinned to zero. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
