The catalogue lists 28 tools whose primary category is MCP servers for testing, as of 2026-09-24. Across all 330 tools, 190 have an agent integration fact that names MCP. This post lists the 28 and explains where the 190 come from.
What the category covers
The category definition reads: "MCP servers exposing browsers, test runners, bug trackers or test management to AI agents." MCP is the Model Context Protocol. An AI agent that supports MCP can call the tools such a server exposes.
A tool lands in this category when the MCP server is the product itself. A platform that also ships an MCP server keeps its own primary category. Those platforms appear in the 190 count below.
The 28 tools
The table is sorted by tool name, A to Z. Surfaces are documented unless marked "not documented". "Yes" in the open-source column means a public repository and licence are recorded. "Not recorded" means the catalogue holds no open-source repository and licence for the tool.

MCP across all categories
As of 2026-09-24, 190 of 330 tools have an agent integration fact that names MCP. For 181 of them the fact is documented, and for 9 it is vendor-stated. Many of these tools sit in other categories. Two examples follow, both documented.
accessFlow is an accessibility testing tool with an MCP server that connects AI clients to its audit results. JetBrains AI Assistant test generation acts as an MCP client that connects to external MCP servers.
So the 190 count covers tools that ship an MCP server and tools that act as MCP clients. Each tool page gives the exact wording of its agent integration fact, with its source.
The MCP integration feature hub lists the 181 documented tools in its main table and the 9 vendor-stated tools separately. The MCP servers category hub lists the 28 tools above with the full fact set.
