You have one MCP server configured: firecrawl. The hang is likely caused by that server failing to start. Let me test it.

The issue is npx -y firecrawl-mcp — it downloads the package every time on startup, causing the hang. The fix is to install it globally so it starts instantly.

Bash Install firecrawl-mcp globally

npm install -g firecrawl-mcp 2>&1

OUT

OUT
/opt/homebrew/bin/firecrawl-mcp
Now update the config to use the global binary directly instead of npx:

Edit [settings.json](vscode-webview://0ajgmlm505hifjk752caao5pkumr1pqngs8iofnusrfffu8tk5em/index.html?id=98cff277-1eb5-4482-b8e4-840f874ba903&parentId=1&origin=dd4e5f64-044c-43f2-b418-fd18a73e9f41&swVersion=4&extensionId=Anthropic.claude-code&platform=electron&vscode-resource-base-authority=vscode-resource.vscode-cdn.net&parentOrigin=vscode-file%3A%2F%2Fvscode-app&session=079c750e-c9dd-4845-ae7d-8e84c574e46b#)
Modified
Done. firecrawl-mcp is now installed globally at /opt/homebrew/bin/firecrawl-mcp and the config points to it directly. Reload the MCP servers panel — it should connect immediately instead of spinning.

The server itself works fine. The extension may need a window reload to pick up the config change, but let me also check if there are other MCP servers configured that might be hanging.

The config change won't take effect until the extension reloads. Try:

Cmd+Shift+P → "Developer: Reload Window"

If it's still spinning after that, check the extension output panel: Cmd+Shift+P → "Claude: Show Output" (or look in the Output panel dropdown for "Claude Code") and share any errors you see there.

i don't see these here
The extension path shows .antigravity — that looks like it might be the Claude desktop app's built-in IDE, not standard VSCode. What editor are you in when you see the "Manage MCP servers" panel?

agent
That's the Claude desktop app. To pick up the config change, you need to fully quit and relaunch the Claude app (Cmd+Q, then reopen it).

If it still spins after that, it may be a built-in issue with the desktop app's agent MCP panel unrelated to firecrawl. Do you see firecrawl listed at all, or is the whole panel just blank and spinning?

Found two relevant errors in the logs:

[warn] Shell environment extraction failed, using process.env
[error] Failed to spawn /usr/bin/sqlite3 (via disclaimer): unable to open database file
The shell env failure means Claude can't read your PATH — which affects MCP server startup. The SQLite error is also preventing project detection.

Let me check if the shell env issue is the root cause:

The shell environment failure means the app has a limited PATH — /opt/homebrew/bin (where firecrawl-mcp lives) isn't in it. Let me fix the config to use the full path:

Edit [settings.json](vscode-webview://0ajgmlm505hifjk752caao5pkumr1pqngs8iofnusrfffu8tk5em/index.html?id=98cff277-1eb5-4482-b8e4-840f874ba903&parentId=1&origin=dd4e5f64-044c-43f2-b418-fd18a73e9f41&swVersion=4&extensionId=Anthropic.claude-code&platform=electron&vscode-resource-base-authority=vscode-resource.vscode-cdn.net&parentOrigin=vscode-file%3A%2F%2Fvscode-app&session=079c750e-c9dd-4845-ae7d-8e84c574e46b#)
Modified
But honestly, the blank/spinning panel looks like it may be a separate issue in the Claude desktop app — the mcp-registry connection failure or the SQLite error might be what's preventing the panel from rendering at all, independent of firecrawl.

Try fully quitting Claude (Cmd+Q) and relaunching. If the panel is still blank after that, it's likely a bug in the app itself (v1.569.0) rather than your config — and worth reporting at github.com/anthropics/claude-code/issues.

settings.json
ok. i'm in antigravity while using claude code
Got it — antigravity is the Claude desktop app's built-in IDE. The MCP panel there reads from the same [.claude/settings.json](vscode-webview://0ajgmlm505hifjk752caao5pkumr1pqngs8iofnusrfffu8tk5em/.claude/settings.json) we already updated.

To pick up the changes, try clicking the refresh/retry button in the "Manage MCP servers" panel (the circular arrow icon next to "Refreshing..."). If that doesn't work, start a new Claude Code session — the MCP server will be initialized fresh with the corrected full path.
