Microsoft Unveils MCP Interviewer for Reliable Agent Collaboration

Microsoft Research has introduced MCP Interviewer, an open-source tool designed to ensure reliable operation of Model Context Protocol (MCP) servers across diverse agentic clients. The tool, released as a command-line interface (CLI), automates compatibility checks and evaluates agent readiness.

MCP Interviewer is built to anticipate a future 'society of agents' where agents from different developers must collaborate. It generates human-readable reports in Markdown and JSON, summarising constraint violations, statistics, and qualitative assessments.

The tool uses large language model agents to create and execute test plans, exercising server tools interactively with detailed logging. However, it acknowledges that large agent tool spaces can lower performance for some models by up to 85% due to overwhelming the LLM's context window.

MCP Interviewer, developed and maintained by Microsoft, is a valuable resource for developers building and maintaining MCP servers. It automates inspections, functional testing, and agentic evaluation, helping to avoid deployment pitfalls and ensuring reliable server operation across diverse clients.
