## 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 2026-10-17.

- **Supply Chain Security**: 100/100
  - No malware found by supply-chain analysis.
  - No known CVEs affecting this package version or its production dependencies.
  - No install/post-install scripts declared.
  - No production dependencies, so there is no dependency health to assess.
- **Provenance & Transparency**: 45/100
  - 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).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 40/100
  - 0% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (fair).
  - Tool/resource definitions use about 480 tokens (~96/item across 5 items; 4 tools + 1 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**: 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 4 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 6 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.

**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.

### 2026-10-11 (score 39)

First indexed and scored.

## MCP tools (4)

### `get_block_reference` (~32 tokens)

Template format reference

The template format: block types and their properties, layout, colors, variables. Read this before writing a template.

### `list_templates` (~52 tokens)

List starter templates

Lists the starter email templates (welcome, newsletter, order confirmation, password reset, …) and the built-in header/footer ids usable in build_email.

Input parameters:

- `category` (string): Only list starter templates in this category

### `get_template` (~66 tokens)

Get a starter template

Returns a starter template to adapt. "tree" (default) is the nested format build_email accepts; "document" is the flat editor JSON.

Input parameters:

- `format` (string): Default: tree
- `name` (string, required): Template name from list_templates, e.g. "welcome"

### `build_email` (~252 tokens)

Build email

Validates a template, renders the final email HTML, lists its variables, and returns a preview link that opens the email in the Easy Email Builder visual editor (where it can be edited and exported). Accepts the tree format ({ layout, header, footer, blocks }) or a flat editor document. On validation errors nothing is rendered; fix them and call again. "warnings" also flags things that break in Outlook or Gmail (nested columns, oversized images, unsupported CSS in raw HTML, clipping); fix those too unless the user accepts them.

Input parameters:

- `documentOutputPath` (string): Also write the flat editor document (JSON) to this file path
- `htmlOutputPath` (string): Also write the HTML to this file path
- `include` (array): What to return besides the preview link and variables. Default: ["html"]. "document" is the flat JSON for the EmailBuilder React component.
- `template` (object, required): The template: { layout?, header?, footer?, blocks: [...] } (see get_block_reference) or a flat editor document
- `variables` (object): Fallback values for contact variables used in the template, e.g. { "first_name": "there" }
