Add gaisho to Claude Code.

Or set it up by hand

1. Add the server

   Run this in your terminal. It adds gaisho for every project under your user.

   $claude mcp add --scope user --transport http gaisho https://mcp.gaisho.co/mcp

2. Sign in

   In Claude Code, run this, select gaisho and authenticate. A browser opens: sign in with Google and click Allow. No key is typed anywhere.

   ›/mcp

3. Install the daily shopping skill

   Save the general shopping skill as ~/.claude/skills/gaisho/SKILL.md so Claude Code knows when and how to use gaisho. The setup prompt does this for you and records the verified connection in the skill.

   $mkdir -p ~/.claude/skills/gaisho && curl -fsSL https://mcp.gaisho.co/shopping.md -o ~/.claude/skills/gaisho/SKILL.md

4. Ask a shopping question

   Try “robot vacuum” or a real question. A saved configuration is not proof; a successful answer is.

No sign-in? Use an API key

Use an API key when sign-in is unavailable, or when calls run from a script or sandbox.

Questions

Can Claude Code set this up by itself?

Yes. Paste the setup prompt and it follows the install guide: connects gaisho, asks you only for the sign-in click, installs the daily skill and checks that everything works.

Does gaisho decide what to buy?

No. gaisho returns facts — products, prices and seller signals — never verdicts such as “worth buying”. Your agent judges.

Which stores does it cover?

US online retail.

I already had gaisho under another name or URL.

Rename the connection to gaisho and update it to https://mcp.gaisho.co/mcp instead of adding a second one.
