APIs are no longer just powering applications — they’re powering AI agents. Gartner’s new Market Overview for API and MCP Testing Tools sizes this market at $582 million in 2026, forecasting growth to approximately $760 million by 2029 as enterprises scale AI agent and Model Context Protocol (MCP) integrations. Qyrus is listed among the example vendors profiled in the report.
What’s Inside the Report
- Market sizing and growth trajectory for API and MCP testing tools through 2029
- Why Gartner sees AI agents and MCP as new integration surfaces that traditional API testing wasn’t built to validate
- The four vendor categories shaping this market — pure-play API testing, software testing platforms, API management, and open source — and the trade-offs of each
- Gartner’s mandatory and optional capability set for evaluating tools, including protocol coverage, contract testing, service virtualization, and AI-assisted test generation
- A directory of example vendors in the space, including Qyrus
Why This Matters for Your Team
Gartner’s research notes that MCP adoption is outpacing the maturity of commercial testing capabilities — only 14% of software engineering leaders say they haven’t incorporated MCP into their architecture at all. That gap is exactly where unified platforms need to prove themselves: supporting REST, GraphQL, and SOAP testing today while building out validation for MCP servers and agent-driven workflows.
Qyrus platform takes the same unified approach — functional, process, and performance testing for REST, SOAP, and GraphQL APIs, backed by AI-assisted test generation (Nova AI) and no-code test building — so teams aren’t stitching together separate tools as MCP and agent testing requirements mature.
Backed by Independent Recognition
Qyrus was also named a Leader in The Forrester Wave™: Autonomous Testing Platforms, Q4 2025, earning a perfect 5.0 score across six evaluation criteria, and delivers a documented 213% ROI with payback in under six months, per a Forrester Total Economic Impact™ study commissioned by Qyrus.
