## 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**: 63/100
  - 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 enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement.
  - 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**: 74/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 281 tokens (~140/item across 2 items; 2 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**: 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 2 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 2 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

### `estimate_cost` (~251 tokens)

Estimate email & SMS marketing cost

Estimated monthly list price (USD, before tax, monthly billing) of email marketing platforms for a given number of contacts and emails per month, optionally with SMS to one destination country. Computed from a fixed table of prices collected from each vendor's official pricing page; each row has the check date, the official source URL and a status (verified/unverified). Only verified prices are used for "cheapest". No feature requirements are applied. Use when the user asks how much an email/newsletter or SMS marketing tool costs for their list size, or wants to compare prices between Mailchimp, Klaviyo, Brevo, MailerLite, Kit (ConvertKit), beehiiv, Substack, Omnisend, GetResponse, ActiveCampaign and HubSpot Marketing Hub.

Input parameters:

- `contacts` (integer, required): Number of contacts/subscribers.
- `emails_per_month` (integer, required): Total emails sent per month (all contacts combined). At most 1000 per contact.
- `sms_country` (string): Optional. SMS destination country (exact name from the list).
- `sms_per_month` (integer): Optional. SMS messages per month (1 SMS = 1 segment). Requires sms_country when above 0.

### `list_vendors` (~30 tokens)

List vendors and pricing sources

Vendors covered by the estimate, with the date their pricing data was checked and the official pricing page URLs.
