Compatible with every major AI agent and IDE
What is the Qualified.io MCP Server?
Connect your Qualified.io account to any AI agent to streamline your technical recruitment and engineering assessment workflows through natural conversation.
What you can do
- Assessment Management — List, create, and manage the lifecycle of your coding assessments, including publishing and archiving.
- Candidate Invitations — Send assessment invitations to candidates and manage active invites directly through the API.
- Result Tracking — Retrieve detailed assessment results and streamlined exhibits to evaluate candidate performance instantly.
- Lifecycle Control — Terminate active results or schedule retries for candidates who need another attempt.
- Cohort Analysis — List and organize assessment cohorts to manage groups of candidates effectively.
How it works
- Subscribe to this server
- Enter your Qualified.io API Key
- Start managing your technical hiring pipeline from Claude, Cursor, or any MCP-compatible client
No more jumping between your ATS and assessment platform to check if a candidate has finished their test. Your AI acts as a technical recruiting coordinator.
Who is this for?
- Engineering Managers — quickly review candidate scores and code exhibits without leaving the dev environment.
- Technical Recruiters — automate the process of inviting candidates and checking status updates.
- Talent Operations — manage large cohorts and assessment versions with simple natural language commands.

How Vinkius secures
Qualified.io for LangChain
Every tool call from LangChain to the Qualified.io MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
Frequently asked questions
Can I see a summary of a candidate's test performance without pulling the full raw data?
Yes. Use the get_assessment_result_exhibit tool. It provides a streamlined view of the candidate's performance, making it easier for your AI to summarize the results for you.
How do I invite multiple candidates to a specific assessment at once?
You can use the invite_candidates tool. Simply provide the assessment ID and the candidate data payload, and the server will handle the invitations through the Qualified.io API.
Is it possible to reopen a test for a candidate who had technical issues?
Yes, you can use the schedule_retry_assessment_result tool with the specific Result ID to allow the candidate to retake or continue their assessment.
How does LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
