OAHelper tools (8)

write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

  • oahelper_company

    List one OAHelper set page by slug or URL, e.g. "kickdrum-mcq24sep" or https://www.oahelper.in/company-questions/kickdrum-mcq24sep. Returns question refs for oahelper_question. For a company by name, use oahelper_search or oahelper_sync.

  • oahelper_interviews

    Interview experiences for a company from OAHelper (12 per page, most relevant first). Saves each full write-up to library/<company>/interviews/ and returns a short list; read the saved files for the full text.

  • oahelper_offline

    What is saved offline. No network call. With no company, lists every company in the library; with a company, returns its index (sets, interviews, counts).

  • oahelper_question

    Read one OAHelper question: full statement, MCQ answers with explanations (for MCQ sets), any saved official solution, and optionally community solutions and images. Saves it to the offline library.

  • oahelper_search

    Find a company's OA question sets on OAHelper by name (e.g. "Amazon", "Kickdrum").

  • oahelper_solution

    Fetch OAHelper's official solution for one coding question (language: cpp, python, java). Each new fetch uses one of the account's limited daily solution requests, so only call this when the user asks for the official solution. Saved solutions are free.

  • oahelper_status

    Session and usage status. online=true also checks Pro status with the site (one request); by default no network call is made.

  • oahelper_sync

    Download one company's OAHelper content into the offline library, newest sets first: set lists, every question statement, MCQ answers, and interview experiences.

oahelper-mcp

Built by Sirjan Singh

An MCP server that lets Claude Code, Claude Desktop, Cursor, Codex or any other MCP client read your own OAHelper Pro account: company OA question sets, full problem statements, MCQ answer keys, official solutions and interview experiences. Everything it fetches is also saved as plain markdown on your disk, so you can prep offline, in Obsidian, or with an agent that never touches the network again.

It also ships 9 skills for mock OAs, MCQ drills, hint-based coaching, interview briefs, study plans and spaced revision.

The server is one small Python package with a single dependency (the official mcp SDK). HTTP is the standard library.

<!-- mcp-name: io.github.SirjanSingh/oahelper-mcp -->

Quick install

The Claude Code plugin asks for your OAHelper cookie when you enable it and keeps it in secure storage. Its skills show up as /oahelper:oa-mock, /oahelper:mcq-drill and so on.

Read this first. OAHelper's Terms of Service forbid automated access and scraping,

and the penalty can be losing your Pro account. This tool is built to be used the way

a person uses the site: one company at a time, only when you ask, 2 seconds between

requests, a hard daily cap (300 by default), and a disk cache so nothing is fetched

twice. It uses your own logged-in browser session, ships no content, and gives you

nothing your plan does not already include. Whether to run it is your decision and

your risk. Do not use it to crawl the site, and never publish or share what it saves.
