How statuses are assigned

Definition and scope

What this capability means

MCP tools are operations advertised by a Model Context Protocol server and made available for a model or agent to invoke.

This row asks whether the named harness can connect to an MCP server and call its tools. It does not claim support for every MCP transport, authentication flow, protocol primitive, or third-party server. Plan, rollout, and transport restrictions are marked partial when the public documentation states them.

Only the current track is sourced in this first wave. Preview and unreviewed harness cells remain unknown.

Evidence
  1. 1. Evidence checked 2026-08-28: ChatGPT developer mode can scan and invoke tools from custom remote MCP apps on ChatGPT web, but full MCP is a beta rollout limited by plan and workspace controls.
  2. 2. Evidence checked 2026-08-28: Claude web supports tools from custom remote MCP connectors on paid plans, and Anthropic labels the feature beta.
  3. 3. Evidence checked 2026-08-28: Claude Desktop supports local MCP servers through desktop extensions and remote MCP connectors, with beta and administrator controls documented.
  4. 4. Evidence checked 2026-08-28: the Claude Code CLI reference exposes `claude mcp` for configuring MCP servers and documents MCP tools in its permission surface.
  5. 5. Evidence checked 2026-08-28: Cursor documents local and remote MCP transports and automatic use of discovered MCP tools by Agent.
  6. 6. Evidence checked 2026-08-28: OpenAI documents MCP as a Codex CLI tool for connecting the local agent to external systems.
  7. 7. Evidence checked 2026-08-28: Gemini CLI documents configured MCP server discovery and invocation of the tools those servers expose.
  8. 8. Evidence checked 2026-08-28: VS Code documents MCP tools as a supported agent tool type and supports local or remote MCP servers in Copilot agent mode.
  9. 9. Evidence checked 2026-08-28: OpenWork Desktop documents workspace or global custom MCP servers, including an OAuth setup path, for use in agent sessions.
  10. 10. Evidence checked 2026-08-28: xAI documents that Grok Bot connects to tools through plugins and MCP servers, while hosted MCP tool calls are run on the Bot computer's behalf; team MCP policy can disable servers or member-added configurations.
