Use Crunch from Claude

Ask your data questions from Claude Code, Claude Desktop or claude.ai.

If you already work in Claude, you can ask your data questions there instead of switching to Crunch. Crunch is a remote MCP server — MCP is the standard way Claude connects to outside tools — so once you add it, Claude can use Crunch to answer questions like “how’s activation trending?”.

The server URL is:

https://sequoia.bumbleb.co/mcp

What you’ll need

A Crunch account, and Claude Code, Claude Desktop or claude.ai.

Add it to claude.ai and Claude Desktop

On claude.ai, open Settings → Connectors and choose Add custom connector.
Name it Sequoia and enter the URL above.
It appears under + in any conversation. Claude Desktop picks it up from your claude.ai account, so there’s nothing more to do there.

Add it to Claude Code

Run this in your terminal:
```
claude mcp add --transport http sequoia https://sequoia.bumbleb.co/mcp
```
Add --scope user to have it in every project, or --scope project to share it with your team through .mcp.json.
If claude mcp list shows Needs authentication, run /mcp in a session, pick sequoia, choose Authenticate, and approve in the browser.
When you see ✔ Connected, it’s ready.

How to tell it worked

Just ask: “how’s activation trending?”. Claude calls Crunch and answers from your data.

Tip: To skip the permission prompt each time, allow mcp__sequoia__* in .claude/settings.json.

If it doesn’t connect

Run curl -I https://sequoia.bumbleb.co/mcp. A 404 or 405 means the server is up; 401 or 403 means it wants you to sign in; nothing at all means a network problem or a typo.
Check for a stray space in a pasted URL.
If it’s slow to start, run MCP_TIMEOUT=60000 claude.
No MCP servers configured means you are in a different project from the one where you added it.

Ask Crunch about your data — how Crunch answers and shows its counting.
Datasets — the data Crunch reads.
