gaisho

Integration · Cursor

Add gaisho to Cursor.

One config entry, a Google sign-in, no API key. Cursor gets product search, price checks and seller vetting across US online retail.

Or set it up by hand

  1. Add the server

    Add this entry under mcpServers in ~/.cursor/mcp.json (every project) or the project's .cursor/mcp.json. Merge it into the existing file; never overwrite it. Leave key and header fields out: the server tells Cursor where to sign in.

    "gaisho": {"url": "https://mcp.gaisho.co/mcp"}

  2. Sign in

    In Cursor's MCP settings, click the gaisho server's login button. A browser opens: sign in with Google and click Allow. No key is typed anywhere.

  3. Install the daily shopping skill

    Save the general shopping skill (shopping.md, linked from the install guide) as SKILL.md in the host's skill location, or in its persistent instructions if it has no skills, so the agent knows when and how to use gaisho. The setup prompt does this for you and records the verified connection in the skill.

  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 fails, or when calls run from a script or sandbox.

  1. Create a key

    In the console, open API Keys and create one. It starts with gsk_ and is shown once. Set it as the environment variable GAISHO_API_KEY, or in the host's secret settings; never paste it into a chat or commit it.

  2. Send the key as a header

    Add the server with the header Authorization: Bearer ${GAISHO_API_KEY}, written in the host's own syntax for environment variables.

Questions

Can Cursor's agent set this up by itself?
Yes. Paste the setup prompt and it follows the install guide: adds gaisho to mcp.json, asks you only for the login 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 belong to an organization. Whose usage is it?
The sign-in page asks whether usage counts toward you or your organization. You choose.
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.
