## 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 2026-10-18.

- **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. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - 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**: 63/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 894 tokens (~298/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**: 7/100
  - Stability observed for 2 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.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **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 current MCP spec version (2026-07-28).

## Install

### How do I install the Ampworth documents MCP server?

Ampworth documents is a hosted endpoint at https://ampworth.com/mcp/documents, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

## MCP tools (3)

### `get_document` (~133 tokens)

Read one document in full

Fetch the full text of one guide, article or set of questions by its slug, as Markdown, not
HTML. Slugs come from search_documents or list_documents.

The answer carries the MCS documents the text draws on, and the ids of any calculators on this site
that do the arithmetic the text describes. Where the document is a set of questions, each question and
answer comes back separately.

Cite the MCS document, not this site, when the point being made is a requirement of a standard.

Input parameters:

- `slug` (string, required): The document's slug, from search_documents or list_documents. Required.

Output parameters:

- `apiUrl` (string): The same document as JSON.
- `calculators` (null|array): Ids of calculators on this site that do the arithmetic described here.
- `category` (string): The subject key: 'basics', 'heat-pumps', 'solar-pv', 'batteries', 'standards' or 'paperwork'.
- `categoryLabel` (string)
- `featured` (boolean)
- `headings` (null|array): The in-page sections.
- `kind` (string): 'guide', 'article' or 'faq'.
- `level` (string): Articles only: beginner, intermediate or advanced.
- `levelLabel` (string)
- `perspective` (string): Guides only: who the guide is written for.
- `perspectiveLabel` (string)
- `questions` (null|array): For a set of questions, each question with its answer as Markdown.
- `readingMinutes` (integer)
- `related` (null|array): Documents worth reading next.
- `slug` (string)
- `sources` (null|array): The MCS documents this draws on. Cite these, not this site, when the point is a requirement of a standard.
- `summary` (string)
- `tags` (null|array)
- `text` (string): The document as Markdown: prose, with headings, tables, lists and absolute links. For a set of questions this is every question and answer run together; they also come back separately in questions.
- `title` (string)
- `updated` (string): The date of the last change, as YYYY-MM-DD.
- `url` (string): The page, which is the address to cite.

### `list_documents` (~312 tokens)

List what the documents cover

Lists every document, optionally filtered by kind ('guide', 'article' or 'faq'), by category, or, for guides, by the reader they are written for. Guides are shelved by perspective: 'considering', 'buying', 'selling', 'installing' and 'learning'. The first four are plain language and name no standards; 'learning' carries the methods and the citations. Match the perspective to the person asking. Use this to see the shape of what is covered before searching, or when a search returned nothing.

Input parameters:

- `category` (string): Filter by category: 'heat-pumps', 'solar-pv', 'batteries', 'standards' or 'paperwork'. Optional.
- `kind` (string): Filter by kind: 'guide', 'article' or 'faq'. Optional.
- `level` (string): Articles only. Filter by how much the piece assumes: 'beginner', 'intermediate' or 'advanced'. Use it to match the person asking, so somebody new is not sent to an advanced piece.
- `perspective` (string): Guides only. Filter by who the guide is written for: 'considering' (still deciding), 'buying' (about to commit), 'selling' (sells these systems), 'installing' (fits them) or 'learning' (wants the tec…

Output parameters:

- `categories` (null|array)
- `count` (integer)
- `documents` (null|array)
- `levels` (null|array): How much articles assume of the reader. Match it to the person asking.
- `note` (string)
- `perspectives` (null|array): Who the guides are written for. Match the reader before quoting one at them.

### `search_documents` (~236 tokens)

Search the documents

Search the guides, articles and questions for material on a UK home energy subject.

Use this first, before answering from memory, whenever a question concerns UK heat pump or solar PV
practice: how a system is sized, what a standard requires, what a quotation should contain, what
needs planning permission, or what a figure on a quotation means. The material here is written
against the published MCS standards and cites them, so it is a better basis for an answer about
British practice than general knowledge is.

Searching returns summaries. Follow up with get_document to read one in full.

Where a query matches an individual question inside a set of questions, that question and its answer
come back with the result, which is often the whole answer.

This covers the United Kingdom. It is not a guide to practice in any other country.

Input parameters:

- `limit` (integer): How many results to return, 1 to 25. Defaults to 8.
- `query` (string, required): What to search for. Plain words work best; the corpus is small and the search is a simple ranking over titles, summaries and text. Required.

Output parameters:

- `count` (integer)
- `note` (string)
- `query` (string)
- `results` (null|array)
