MCP clients - verified

MCP client support matrix

24 MCP clients, from coding agents and editors to desktop apps and SDKs, checked against their own docs. All 24 document calling server tools. 22 of 24 document the Streamable HTTP transport, 19 document OAuth sign-in for remote servers and 13 document elicitation, while only 2 (VS Code (GitHub Copilot agent mode) and GitHub Copilot CLI) document sampling.

Method

How to read this matrix

Values come from each client's own docs and the official MCP clients pages on modelcontextprotocol.io, read on and re-checked independently. Clients ship weekly; check the linked source before you rely on a feature.

Yes, No, Not stated
Yes and No appear only when the client's own docs, or the official MCP pages, say so, and each links to the page that says it. Not stated means the docs neither claim nor rule out the feature; it is not a No.
Config copied verbatim
Config examples come from the page linked under each one, unchanged, including the placeholder names the docs use. A client whose docs publish no example gets none here.
Not a ranking
Nothing here measures quality or speed. The matrix lists documented support only, and the order follows the data file.

Which MCP clients support sampling?

2 of 24 MCP clients document sampling, where a server asks the client's model for a completion: VS Code (GitHub Copilot agent mode) and GitHub Copilot CLI. Claude Desktop / claude.ai, Zed, goose, LangChain MCP adapters and Mastra document that they do not. The docs of Claude Code, Claude Agent SDK, OpenAI Codex CLI, ChatGPT (apps / connectors), OpenAI Agents SDK, Cursor, Windsurf, JetBrains AI Assistant, Cline, Gemini CLI, Kiro, opencode, Continue, LM Studio, Microsoft Copilot Studio, Vercel AI SDK and Raycast do not say.

Which MCP clients can run local stdio servers?

22 of 24 MCP clients document the stdio transport, which starts a local server as a subprocess: Claude Code, Claude Desktop / claude.ai, Claude Agent SDK, OpenAI Codex CLI, ChatGPT (apps / connectors), OpenAI Agents SDK, Cursor, VS Code (GitHub Copilot agent mode), Windsurf, Zed, JetBrains AI Assistant, Cline, Gemini CLI, GitHub Copilot CLI, Kiro, goose, opencode, Continue, Vercel AI SDK, LangChain MCP adapters, Mastra and Raycast. The docs of LM Studio and Microsoft Copilot Studio do not say.

What does "Not stated" mean in the matrix?

That the client's official docs, read on October 18, 2026, neither claim nor rule out the feature. It is not a No: the feature may work without being documented. Yes and No appear only when the docs say so, and each links to the page that says it.

Where do these values come from?

From each client's own documentation and the official MCP pages on modelcontextprotocol.io, read on October 18, 2026 and re-checked independently. Config examples are copied verbatim from the page linked under each one. Nothing here is a benchmark or a ranking; the order follows the data file.
