MCP across Microsoft surfaces

Model Context Protocol — the open MCP standard from Anthropic — is now wired into multiple Microsoft surfaces: VS Code (agent mode), GitHub Copilot, Copilot Studio (MCP as an action source), the Microsoft 365 Agents Toolkit (scaffolding MCP plugins for M365 Copilot), and Foundry Agent Service. Status differs per surface — some GA, some preview. Pages below are sourced from official Microsoft Learn docs across each surface.
