Whether each client interface allows connecting a custom MCP server, gated by plan. Voice modes are broken out because they usually don't expose tool calls even when the same account can use MCP in text chat.
Google offers a separate Gemini Enterprise SKU on Google Cloud (distinct from Workspace-with-Gemini) that does support custom MCP servers as Data Store connectors — but it's a developer/cloud product, not a consumer surface. On AI Ultra, Spark connectors are MCP under the hood, but the list is curated by Google BD (Canva, OpenTable, Dropbox, Instacart, Zillow, etc.) with no user-submission path.
Distinct from the VS Code Copilot Chat extension: `npm install -g @github/copilot` installs a standalone headless CLI (`copilot -p "prompt"`) authenticated via OAuth or fine-grained PATs (classic PATs not supported). Same Copilot subscription tiers gate access, but admin policies for the CLI may differ from IDE policies.
Custom remote MCP connectors launched March 13, 2026 for Pro/Max/Enterprise. Enterprise data connectors use the same MCP client surface. Comet Browser and Voice Assistant do not currently expose user MCP servers.
Bring Your Own MCP shipped May 6, 2026 across Web/iOS/Android. ~14 first-party connectors plus custom MCP URL entry at grok.com/connectors. Connectors and BYO MCP require a paid tier (SuperGrok or higher); Free tier does not surface the connectors menu. Voice Agent API Remote MCP is a developer-API capability, not exposed to consumer Voice Mode.
MCP support is uniform across IntelliJ, PyCharm, WebStorm, RubyMine, etc. — IDE differences are about which plan is required to use AI Assistant at all, not MCP itself.
No native MCP support as of Ollama v0.31 (June 2026); tracking issue #7865 is still open and upstream MCP PR #13700 was closed unmerged in May 2026. MCP works only via third-party bridges (mcphost, ollmcp, ollama-mcp-bridge) sitting in front of Ollama's tool-calling API.
