## 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**: 74/100
  - 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.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - 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**: 64/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 663 tokens (~221/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 10/100
  - Stability observed for 3 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 95/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 86% 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 3 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## Install

### How do I install the Tuper Site Check MCP server?

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-11-04 (score 70, +1)

No change was recorded against any check on this day. Stability & Change Management went from 3 to 7. That category is still filling its 30-day observation window: 1 days of observed history at the previous scan, 2 at this one. The score rises as the window fills, whether or not the server changes.

## MCP tools (3)

### `check_site` (~136 tokens)

Check a website

Run a free Tuper Site Check on a public website (measured in a real browser): returns a 0-100 score, counts by severity, the top 5 problems (what, why it matters, where) and the full report URL. Takes 20-90 s. If still running after wait_seconds, returns status "running" and an id for get_report.

Input parameters:

- `url` (string, required): Public site address, e.g. "example.com" or "https://example.com/pricing"
- `wait_seconds` (integer): How long to wait for the result before returning the id (0 = do not wait)

### `check_agent_ready` (~199 tokens)

Check if AI agents can use a website

Run a free Tuper Agent-Ready Check on a public website: can AI agents reach, read and use it? Checks robots.txt rules for 12 AI bots (answer bots scored, training bots info only), llms.txt (llmstxt.org format), bot walls and captchas on the sign-up/login/contact pages, text only after JavaScript, sitemap, JSON-LD and prices, MCP/A2A cards, OpenAPI. Returns a 0-100 score, a headline per group, every fail and warning with what to change, and the report URL. Takes 5-30 s. How 40 famous sites score: https://check.tuper.app/agent-ready/league/?src=mcp-league

Input parameters:

- `url` (string, required): Public site address, e.g. "example.com"
- `wait_seconds` (integer): How long to wait for the result before returning the id (0 = do not wait)

### `get_report` (~91 tokens)

Get a Site Check report

Read a Site Check report by id (from check_site): status (queued, running, done, error), and when done the score, the top findings (up to 20 with all=true) and the report URL.

Input parameters:

- `all` (boolean): true = up to 20 findings instead of 5
- `id` (string, required): Report id from check_site
- `wait_seconds` (integer)
