## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, 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 2026-08-20.

- **Supply Chain Security**: 100/100
  - No malware found by supply-chain analysis.
  - No known CVEs affecting this package version or its production dependencies.
  - Runs hatchling.build at install time, a recognised native-build step with no shell scripting around it.
  - 1 of 30 dependencies flagged as unhealthy.
- **Provenance & Transparency**: 48/100
  - Source repository is publicly reachable at the declared URL.
  - Provenance check failed: no build-provenance attestation is published.
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 5 days ago).
  - Publishes a security disclosure policy (SECURITY.md).
- **Schema Quality & AI Usability**: 70/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 619 tokens (~56/item across 11 items; 11 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **Tool Coverage**: 67/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% of tool parameters carry a description.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

**Unverified: 1 category.** A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

First indexed and scored.

## MCP tools (11)

### `preview_email` (~137 tokens)

Validate and render an email WITHOUT sending it. Returns the exact
payload that would go to SendGrid plus a single-use confirm_token
(valid 10 minutes). Sending requires passing that token to send_email —
there is no direct-send path. BCC is not accepted by design.

Input parameters:

- `body_html` (string)
- `body_text` (string)
- `cc`
- `from_email` (string, required)
- `from_name` (string)
- `reply_to` (string)
- `subject` (string)
- `template_data`
- `template_id` (string)
- `to` (array, required)

### `send_email` (~71 tokens)

Send the email previously rendered by preview_email. Accepts ONLY a
confirm token — the payload cannot be altered between preview and send.
Tokens are single-use and expire after 10 minutes. In dry-run mode
(the default) this simulates and audits but sends nothing.

Input parameters:

- `confirm_token` (string, required)

### `add_suppression` (~54 tokens)

Add an address to a suppression list (default: global unsubscribes).
Suppressing is the SAFE direction — it stops future sends to the address.

Input parameters:

- `email` (string, required)
- `kind` (string)

### `remove_suppression` (~80 tokens)

Remove an address from a suppression list. DANGEROUS direction — it
re-enables sending to someone who bounced or unsubscribed, which can be a
compliance violation. Requires confirm=true, is rate-limited, and audited.

Input parameters:

- `confirm` (boolean)
- `email` (string, required)
- `kind` (string, required)

### `list_templates` (~17 tokens)

List transactional email templates (dynamic + legacy).

### `get_template` (~28 tokens)

Fetch one template with its versions (subject + content preview).

Input parameters:

- `template_id` (string, required)

### `get_email_stats` (~68 tokens)

Global email stats (requests/delivered/opens/clicks/bounces/spam)
from start_date (YYYY-MM-DD). aggregated_by: day|week|month.

Input parameters:

- `aggregated_by` (string)
- `end_date` (string)
- `start_date` (string, required)

### `list_suppressions` (~45 tokens)

List a suppression list: unsubscribes|bounces|blocks|spam_reports|invalid_emails.

Input parameters:

- `kind` (string)
- `limit` (integer)

### `check_suppression` (~49 tokens)

Check whether an address appears on any suppression list. Run this
before drafting mail to someone — sending to suppressed addresses hurts
deliverability and may violate consent.

Input parameters:

- `email` (string, required)

### `get_domain_auth` (~29 tokens)

List authenticated sending domains and their DNS validity — the
first thing to check when deliverability drops.

### `server_status` (~41 tokens)

This server's security posture: mode, rate-limit remaining, allowlist,
caps, audit-log path, and whether an API key is present (never the key).
