VSCode extension does not surface claude.ai account connectors (MCP) that the CLI exposes — same version 2.1.156

What's Wrong?

claude.ai account-scoped remote connectors (Canva, POSCAKE, Webcake, Google Drive — namespace mcp__claude_ai_) do not surface inside the Claude Code VSCode extension. The /mcp panel lists only the project-scoped stdio server (playwright), and ToolSearch / deferred-tool resolution returns nothing for mcp__claude_ai_Canva__.

The CLI of the exact same version (2.1.156), on the same machine and same account, lists all of these connectors as "✓ Connected" via claude mcp list. Per the docs, claude.ai connectors load when the active auth is the claude.ai subscription — which it is (verified via /usage → Auth method: Claude AI, plan: Max).

What Should Happen?

The VSCode extension should surface the same claude.ai account-scoped connectors that the CLI does (Canva, POSCAKE, Webcake, Google Drive). They should appear in /mcp and be resolvable via ToolSearch as mcp__claude_ai_* tools, since they are account-scoped and the active auth is the claude.ai subscription.

Error Messages/Logs

No error is shown — the connectors are silently absent from the extension session.

CLI `claude mcp list` (same machine, same version 2.1.156) returns:
claude.ai POSCAKE LEO: https://mcp-pos.pancake.biz/mcp - ✓ Connected
claude.ai Webcake Leo: https://mcp.toolvn.io.vn/mcp - ✓ Connected
claude.ai WordPress.com: https://public-api.wordpress.com/wpcom/v2/mcp/v1 - ! Needs authentication
claude.ai Canva: https://mcp.canva.com/mcp - ✓ Connected
claude.ai Google Drive: https://drivemcp.googleapis.com/mcp/v1 - ✓ Connected
playwright: - ✓ Connected

In the VSCode extension, /mcp shows ONLY:
playwright - ✓ Connected

Steps to Reproduce

1. Sign in to the Claude Code VSCode extension with a claude.ai subscription account (Max plan).
2. Enable one or more claude.ai connectors (e.g. Canva) at claude.ai → Settings → Connectors.
3. In the extension, open /mcp → only project-scoped stdio servers appear (playwright); no claude.ai connectors.
4. Open a terminal on the same machine and run claude mcp list → all claude.ai connectors appear as "✓ Connected".

Tried and did NOT resolve it: reconnect in claude.ai Settings → Connectors; fresh session; "Developer: Reload Window"; full Sign Out + Sign In + Reload.

Additional Information

Ruled out as a user-config issue:

• ANTHROPIC_API_KEY, ANTHROPIC_AUTH_TOKEN, CLAUDE_CODE_OAUTH_TOKEN: empty at Windows User, Machine, and Process scopes.
• No disableClaudeAiConnectors and no apiKeyHelper in settings.
• Auth confirmed = claude.ai subscription (Max) via /usage.
• The connectors are listed in ~/.claude.json under claudeAiMcpEverConnected.

Since the same-version CLI surfaces all connectors while the VSCode extension surfaces none, this appears specific to the VSCode extension's bridging of claude.ai account connectors.
