HackerRank Work is a platform for coding interviews and technical assessments. It helps teams evaluate developers with real-time collaboration and data-driven hiring.

3 Tools

Introduction

Claude is Anthropic's AI assistant, available on the web, in the desktop app, and on mobile. Cowork is its agent for knowledge work, and it runs on all of those surfaces too. Connected to your apps, Claude can work with your files and services to accomplish complex tasks on your behalf.

This guide walks you through the easiest and most secure way to connect your HackerRank Work account to Claude via Composio Connect, enabling it to schedule a new coding assessment for a candidate, show interview feedback for John Smith, list all pending technical interviews this week, and more such actions on your behalf without compromising your account security.

Setup is the same on Claude Web, Desktop, and Cowork, and you only need to do it once. The connector is tied to your account, so it's available in all three.

3. Connect your HackerRank Work account

Back in Claude, ask it to connect to HackerRank Work or give it any HackerRank Work-related task.

For example, ask Claude to:

  • "Schedule a new coding assessment for a candidate"
  • "Show interview feedback for John Smith"
  • "List all pending technical interviews this week"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Claude, and your HackerRank Work account is ready to use.

What is the HackerRank Work Claude Connector, and what's possible with it?

The HackerRank Work MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your HackerRank Work account. It provides structured and secure access so your agent can perform HackerRank Work operations on your behalf.

Troubleshooting

1. Why does Claude not use the Composio connector for HackerRank Work?

The connector can show as connected, but Claude must use it in each HackerRank Work conversation.

  • Click + at the lower left of the chat, or type /.
  • Hover Connectors.
  • Turn on Composio.
  • Ask Claude to connect to HackerRank Work again.

2. Why does Claude show an MCP server error before HackerRank Work connects?

Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for HackerRank Work.

  • Check that the connector URL is https://connect.composio.dev/mcp.
  • Connectors run from Anthropic's cloud, so your device network is usually not the problem.
  • Add the connector again from Customize > Connectors, then ask Claude to connect HackerRank Work.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the HackerRank Work authorization link not work?

The Composio connector is one server. Your HackerRank Work account connects separately when Claude asks for it.

  • If the browser does not open, or the link expires, ask Claude to retry the HackerRank Work connection.
  • Composio creates a fresh HackerRank Work authorization link.
  • Open that link in your browser and finish the HackerRank Work sign-in.

4. Why do HackerRank Work actions fail after they worked before?

The HackerRank Work connection can expire or lose permission.

  • Ask Claude to inspect the HackerRank Work connection.
  • If the connection is unhealthy, disconnect it when Claude prompts you.
  • Reconnect the HackerRank Work account and retry the action.
  • If Claude shows a permission prompt, approve it before Claude changes data in HackerRank Work.
  • If the action still fails with a permission error, check that the connected account has that permission in HackerRank Work itself.

5. How do I switch to a different HackerRank Work account?

Claude can manage the HackerRank Work connection for you.

  • Ask Claude to disconnect or delete the current HackerRank Work account.
  • Ask Claude to connect HackerRank Work again.
  • Open the new Composio authorization link for HackerRank Work.
  • Sign in with the other HackerRank Work account in the browser.
  • After the account connects, ask Claude to retry the HackerRank Work task.

6. Why is my HackerRank Work connection missing in Claude Desktop or on a Team plan?

The connector belongs to your Claude account, so your HackerRank Work connection works in Claude Web, Desktop, and Cowork.

  • In Claude Desktop, open Customize > Connectors.
  • Next to Composio, click ⋮ and click Clear cache.
  • If HackerRank Work tools still do not appear, click ⋮, disconnect, remove the connector, and add it again.
  • On Team or Enterprise, an Owner or Primary Owner must enable the connector before you can connect HackerRank Work.

FAQ

Frequently asked questions

With a standalone HackerRank Work MCP server, the agents and LLMs can only access a fixed set of HackerRank Work tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from HackerRank Work and many other apps based on the task at hand, all through a single MCP endpoint.

Yes, you can. Claude Cowork fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right HackerRank Work tools.

Yes, absolutely. You can configure which HackerRank Work scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your HackerRank Work data and credentials are handled as safely as possible.
