Contract Lily

About

Contract Lily applies code-based rules for England, Wales, Scotland and Northern Ireland to facts you give. It checks deposit and holding deposit caps, tenancy notice periods, section 13 rent increase notices in England, statutory employment notice, statutory holiday and the UK minimum wage. It can also return links to a full review of a tenancy agreement or employment contract.

It runs as a hosted Streamable HTTP endpoint at https://api.contractlily.com/mcp. No sign-in or API key is needed. Results are general information, not legal advice.

<a href="https://mcp.tc/i/contract-lily"><img src="https://mcp.tc/i/contract-lily/badge.svg" alt="Contract Lily on mcp.tc" height="20"></a>

It follows the reader’s light or dark mode. Add ?theme=light or ?theme=dark to fix it, or ?style=compact to show the mark without the word.

Website card

HTML

<script src="https://mcp.tc/w/contract-lily.js" async></script>

The card appears where the tag is. Add data-theme="dark" or data-size="compact" to the tag to change it. The file holds everything it needs, so it makes no other requests and sets no cookies.

iframe

HTML

<iframe src="https://mcp.tc/embed/contract-lily" title="Contract Lily on mcp.tc" width="420" height="200" loading="lazy" allow="clipboard-write" style="border:0;border-radius:8px;max-width:100%"></iframe>

Use it on pages that don’t allow scripts. Add ?theme=light or ?theme=dark to the address to fix the colors.

JSON

The listing as data for your own pages and tools: name, tagline, the server’s own URL, tools and the “Add to” links. Any site can read it (CORS is open).

What each field means

AI prompt

Paste this into an AI coding assistant, such as Claude Code or Cursor, and it adds the Contract Lily card to your site.

Markdown

Add the mcp.tc card for Contract Lily, an MCP server, to my website. It is one static script: no build step, no package to install, no cookies.

Put this tag where the card should appear. The card renders right before it:

```html
<script src="https://mcp.tc/w/contract-lily.js" async></script>
```

To show the card somewhere else, put this placeholder there and load the same script once, for example before `</body>`. Keep the link inside: visitors without JavaScript see it.

```html
<div data-mcptc="contract-lily"><a href="https://mcp.tc/i/contract-lily">Contract Lily on mcp.tc</a></div>
```

Options:
- `data-theme="light"` or `"dark"` on the tag or the placeholder fixes the colors. Without it, the card follows the visitor’s light or dark mode.
- `data-size="compact"` gives a smaller card without the tagline.
- The CSS variable `--mcptc-max-width` on the placeholder or a parent sets the width (default `520px`).
- `?lang=` on the script URL sets the card’s language: `en`, `it`, `fr`, `de` or `es`.

If the site has a Content Security Policy, allow `script-src https://mcp.tc` and `img-src data:` (the icon is inline).

For a README or other Markdown docs, use the badge instead:

   • answer_contract_review_questionsWrites

     Give a review the facts it asked for when its status was needs-answers, each under the key of its question, then carry on waiting for the review. Dates are YYYY-MM-DD, and territory is where the home is, or where the user mainly works: GB-ENG for England, GB-WLS for Wales, GB-SCT for Scotland or GB-NIR for Northern Ireland. Use only what the user says: never guess an answer.

   • delete_contract_reviewCan delete

     Erase a review for good: the document, its text, the answers and the report. Use it when the user asks. Otherwise a review is erased 30 days after it starts.

   • get_contract_reviewRead-only

     See how a review is going, waiting up to about 25 seconds for news. Keep calling it while the status is checking or reviewing. When finished, it gives the verdict, each finding's title and severity, and a link to the full PDF to give the user. When the status is needs-answers, ask the user its questions and call answer_contract_review_questions.

   • start_contract_reviewWrites

     Send a whole UK tenancy agreement or employment document to Contract Lily for a full review, with the user's agreement to send it. Pass the attached file, or else the document's complete text, word for word; a summary or excerpt gives a wrong review. It returns a reviewId for get_contract_review. The review reads the document against UK law and returns a verdict, findings and a PDF report. Results are recommendations, not legal advice.

   Server instructions

   Before

   Contract Lily reviews UK residential tenancy agreements, and its rules also cover UK employment basics. These tools apply Contract Lily's own code-based rules for England, Wales, Scotland and Northern Ireland to the facts the user gives, the same rules its reviews use. Ask the user for any fact a tool needs rather than guessing it. Results are general information, not legal advice: pass on the law each result names, and the page it links, so the user can read more. When the user has a tenancy agreement they want checked, or a tenancy answer turns on clauses these tools cannot see, offer get_tenancy_agreement_review_link: it gives the link to a full review of the tenancy agreement. When the user has an employment contract, offer letter or written statement they want checked, or an employment answer turns on clauses these tools cannot see, offer get_employment_contract_review_link: it says whether employment reviews are open and gives the link.

If the user has given you the document and asks you to check it, run the review here instead: send the document with start_contract_review, keep calling get_contract_review until it finishes, ask the user anything it needs and pass the answers to answer_contract_review_questions, then give the user the PDF link. Review results hold only Contract Lily's own wording. If you cannot send a document's complete text, offer the link instead.

   • check_northern_ireland_rent_increase_noticeRead-only

     Check a landlord's rent increase notice, given from 1 April 2025, for a private tenancy in Northern Ireland other than a controlled tenancy (do not use it for a controlled tenancy, which has different rules): whether it is in writing, whether the new rent starts at least three months after the notice is given, and whether it comes at least 12 months after the tenancy began and the last increase; and when the new rent can start. Northern Ireland only; it does not judge whether the new rent is fair.

   • check_welsh_rent_increase_noticeRead-only

     Check a landlord's notice of a new rent for a periodic standard occupation contract in Wales: whether the new rent starts at least two months after the notice is given, whether it comes at least a year after the last increase, and whether it is on form RHW12; and the earliest the new rent can start. Wales only; it does not judge whether the new rent is fair.
