# Mockly English for developers and AI agents

> Every machine-readable file Mockly English publishes for AI agents and crawlers: llms.txt, a markdown version of every page, the fact sheet, the endpoint index and an MCP server that lets ChatGPT, Claude and other agents run the Mini Apps and book coaching sessions.

Mockly English is three things:

1. Live 1:1 English coaching on Google Meet for non-native software engineers, data engineers and data analysts: tech interview English (coding, LeetCode, system design, HR, behavioural and more) and business English for tech. Coaches are practising data engineers who also teach English. Free 30-minute trial, no card needed.
2. Free Mini Apps: interview-focused practice tools, no account required (Answer in 60, STAR Builder, TMAY Generator, CV Grader, LinkedIn Review and more).
3. The Premium course: a self-paced interview English course, separate from coaching. It does not include a session.

## MCP server

`https://app.mocklyenglish.com/mcp` is an MCP server (Streamable HTTP). Its tools run the same logic as the free Mini Apps, show coach availability and book sessions. Most tools need no account. Booking tools use OAuth 2.1 (PKCE, dynamic client registration or client ID metadata documents): the student signs in to Mockly once and the assistant books as them. For students, the walkthrough is at [/ai](https://app.mocklyenglish.com/ai).

- `check_cv_english`: Review the English of CV bullet points and rewrite them
- `rewrite_star_story`: Split a behavioural story into STAR and return a spoken script
- `build_tell_me_about_yourself`: Draft a 'tell me about yourself' answer from a CV
- `get_mockly_english_facts`: Checked facts, coaches, prices and the free trial link
- `get_coach_availability`: Free times with coaches Sophie and Tom, no account needed
- `book_session`: Book the free trial or a paid session for the signed-in student (sign-in required)
- `get_my_sessions`: The signed-in student's upcoming sessions and credits (sign-in required)
- `get_booking_link`: A booking-page link with coach and session chosen, for apps without sign-in
- `find_mockly_english_resources`: Find Mini Apps and guides for a topic

**Claude:** Settings → Connectors → Add custom connector, and paste the URL. **ChatGPT:** Settings → Apps & Connectors → Advanced → Developer mode, then Create, paste the URL and choose OAuth. Other clients can use the URL directly. The server card is at [/.well-known/mcp.json](https://app.mocklyenglish.com/.well-known/mcp.json).

OAuth metadata: [/.well-known/oauth-protected-resource/mcp](https://app.mocklyenglish.com/.well-known/oauth-protected-resource/mcp) and [/.well-known/oauth-authorization-server](https://app.mocklyenglish.com/.well-known/oauth-authorization-server). There is no public REST product API or OpenAPI spec. Everything else we publish is read-only content, listed below, which agents can fetch without a key.

## Every page as markdown

Add `.md` to any page URL to get that page as clean markdown, for example [/mini-apps/star-builder-in-english.md](https://app.mocklyenglish.com/mini-apps/star-builder-in-english.md) or [/faq.md](https://app.mocklyenglish.com/faq.md). The homepage is [/index.md](https://app.mocklyenglish.com/index.md). The markdown is made from the same content as the HTML page, and unknown paths return 404.

You can also request a page URL with `Accept: text/markdown`. Each page advertises its markdown version with `<link rel="alternate" type="text/markdown">` and an HTTP `Link` header.

```
curl https://app.mocklyenglish.com/faq.md
curl -H "Accept: text/markdown" https://app.mocklyenglish.com/faq
