## 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. 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.
  - 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**: 75/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 473 tokens (~157/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**: 67/100
  - Stability observed for 20 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 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.

## MCP tools (3)

### `check_ssl` (~169 tokens)

Quick HTTPS / SSL check

Checks the HTTPS setup of a public website in a few seconds: TLS certificate (issuer, expiry, trust, name), negotiated TLS version, redirect from HTTP to HTTPS and security headers (HSTS, CSP, X-Frame-Options, X-Content-Type-Options, Referrer-Policy). Returns the issues found, most severe first, and a link to the full graded SSL/TLS audit. Passive and non-intrusive: one TLS handshake and two page requests, like a browser visit.

Input parameters:

- `domain` (string, required): Host name of the website, e.g. "example.com" or "https://www.example.com/".
- `language` (string): Language of the answer: "fr" for French, "en" for English (default). Use the language of the conversation.

### `search_cyber_knowledge` (~127 tokens)

Search the KrakenShield cybersecurity library

Searches the free KrakenShield Knowledge Center: cybersecurity glossary, acronyms, security certifications (CISSP, OSCP, ISO 27001...) and the "Cyber from A to Z" guide. Returns short passages with the URL of each page to cite. Use a few precise keywords.

Input parameters:

- `language` (string): Language of the answer: "fr" for French, "en" for English (default). Use the language of the conversation.
- `query` (string, required): A few keywords, e.g. "HSTS preload" or "NIS2 obligations".

### `get_pricing` (~86 tokens)

KrakenShield prices

Current prices of KrakenShield: cost of each audit (SSL/TLS and surface, privacy, code analysis, penetration test) and of Cyber Academy training in Kredits, and the price of Kredit packs in euros excluding VAT.

Input parameters:

- `language` (string): Language of the answer: "fr" for French, "en" for English (default). Use the language of the conversation.

## Common questions

### What is the KrakenShield MCP server?

KrakenShield is an MCP server listed in the public MCP registry as eu.krakenshield/krakenshield. Quick HTTPS/SSL check of any website, cybersecurity glossary and KrakenShield prices. This page covers its hosted endpoint (https://api.krakenshield.eu/mcp).

### Is the KrakenShield MCP server safe to use?

KrakenShield scores 83 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 KrakenShield MCP server expose?

KrakenShield exposes 3 tools: check_ssl, search_cyber_knowledge, get_pricing. Their descriptions and schemas cost roughly 382 tokens of context every time the server is loaded.

### Does the KrakenShield MCP server require authentication?

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

### Is the KrakenShield MCP server still maintained?

KrakenShield 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 KrakenShield MCP server?

VerifyMCP ran 13 checks on KrakenShield, covering TLS certificate, Authorization, HTTPS, HSTS header and 9 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.
