## 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. Nothing on it is marked destructive, but we can't show that an anonymous caller can only read: full credit needs the server to list at least one tool and every tool to be verifiably read-only. We use a best-effort check of tool names and descriptions to tell read-only tools from tools that change things, so some genuinely read-only tools may not get full credit. Names that start with a read verb (get, list, read, search and similar) and accurate readOnlyHint annotations help. Meet that to earn full credit, or require authorisation.
  - 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**: 80/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 559 tokens (~139/item across 4 items; 3 tools + 1 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 3/100
  - Stability observed for 1 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% 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 5 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.
  - Supports UI / widget rendering.

## MCP tools (3)

### `check_site_email_security` (~108 tokens)

Check email authentication and site security

Checks whether a domain's email is likely to reach the inbox (SPF, DKIM and DMARC records, mail servers) and whether the website has basic security in place (HTTPS, security headers, WordPress exposure, Lovable/Supabase setup). Reads only public DNS records and the public home page. The report is written in Portuguese.

Input parameters:

- `url` (string, required): Public address of the site to check, e.g. 'example.com' or 'https://example.com'.

### `check_ai_built_app` (~175 tokens)

Check an app built with AI tools

Reads the public pages and public JavaScript of a web app (typically built with Lovable, Bolt, v0, Replit or similar) and reports exposed API keys, public source maps, missing security headers, stale deploys, missing error monitoring and AI model calls made from the browser. Passive check: it never logs in, submits forms or probes private routes.

Input parameters:

- `language` (string): Language of the report: 'pt' (Portuguese) or 'es' (Spanish). Use the user's language; default 'pt'.
- `sends_user_data_to_ai` (string): Optional. Whether the user says the app sends its users' data to an AI model.
- `url` (string, required): Public address of the site to check, e.g. 'example.com' or 'https://example.com'.

### `diagnose_shopify_store` (~114 tokens)

Diagnose a Shopify store

Reads the public pages of a Shopify store and reports whether it offers social login and a wishlist, how many products show as sold out, and whether it runs storefronts for several countries. Reads only public pages.

Input parameters:

- `language` (string): Language of the report: 'pt' (Portuguese) or 'es' (Spanish). Use the user's language; default 'pt'.
- `url` (string, required): Public address of the site to check, e.g. 'example.com' or 'https://example.com'.

## Common questions

### What is the RealMarket Site Check MCP server?

RealMarket Site Check is an MCP server listed in the public MCP registry as com.realmarketlabs.tools/site-check. Passive checks of a public website: email authentication (SPF, DKIM, DMARC) and basic security. This page covers its hosted endpoint (https://tools.realmarketlabs.com/mcp/site-check).

### Is the RealMarket Site Check MCP server safe to use?

RealMarket Site Check scores 72 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the RealMarket Site Check MCP server expose?

RealMarket Site Check exposes 3 tools: check_site_email_security, check_ai_built_app, diagnose_shopify_store. Their descriptions and schemas cost roughly 397 tokens of context every time the server is loaded.

### Does the RealMarket Site Check MCP server require authentication?

No. We connected to RealMarket Site Check without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the RealMarket Site Check MCP server still maintained?

RealMarket Site Check is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What did VerifyMCP test on the RealMarket Site Check MCP server?

VerifyMCP ran 14 checks on RealMarket Site Check, covering TLS certificate, Authorization, HTTPS, HSTS header and 10 more. Supply Chain Security and Provenance & Transparency do not apply to a hosted endpoint, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
