Glean

Verification notes: Re-checked this pass. MCP support remains extensively documented, now organized under a dedicated MCP Gateway that lets a server be registered once and distributed to Claude, ChatGPT, Cursor, Gemini, Microsoft Copilot, and Claude Code from a single catalog, with tools resolving against Glean's permission-aware Knowledge Graph rather than exposing siloed native MCP servers. Glean's own benchmarking blog claims Glean-routed tools were preferred roughly 2.5x as often as off-the-shelf MCP tools and used 30% fewer tokens in Claude Cowork specifically — that's Glean's own comparative claim, not independently reproduced here. Remote MCP servers are documented as still in beta. No A2A support confirmed. Re-checked this pass: MCP Gateway and remote MCP server support (beta) unchanged; no material change to flags this pass.
