Direct answer

Add Zambo MCP to Gemini CLI

Paste https://zambo.dev/mcp into the Gemini CLI settings and restart the CLI. Open settings.json (in your Gemini config folder, usually ~/.gemini/settings.json), add the Zambo entry below under mcpServers, save, and start a new Gemini CLI session. It then has Zambo: 153 tools in total, 35 on the default surface, and a checkable receipt for every tool call.

The config snippet

Open settings.json in your Gemini config folder. For a project-only setup, the same block works in the project's .gemini/settings.json. Add this entry, keeping any servers you already have:

{
  "mcpServers": {
    "zambo": {
      "httpUrl": "https://zambo.dev/mcp"
    }
  }
}

Note the field name: for a remote HTTP server, Gemini CLI uses httpUrl. There is no command to add, because Zambo is hosted, not run locally.

Verify the connection

Start a new Gemini CLI session and use its MCP listing command (the /mcp command in the session) to see the configured servers. Zambo should show as connected with its tools discovered. If the list is empty, the CLI is reading a different settings file than the one you edited, so check whether you edited the user settings or a project settings file.

Your first tool call

Ask for something small and checkable, for example: ask Gemini CLI to use Zambo to look up a current price or audit a web page. The answer comes back with a receipt link. Open the receipt page, then paste its ID into zambo.dev/verify: the check confirms the saved result was not changed after the fact.

For $0.99, a Day Pass covers 24 hours of full use. Ongoing use is the Zambo Pass at $29 a month or $290 a year, and $19 a month for $ZAMBO holders. Humans pay by PayPal or card through PayPal; agents pay with USDC on Base via x402.

Troubleshooting

Honest limits

A settings entry in the user folder applies to every Gemini CLI session on that machine; a project settings entry applies only inside that project, so pick the scope you actually want. Zambo receipts prove the saved result of a tool call was not changed after the fact. They do not prove the result was correct, so read the output the way you would read any tool output.

Frequently asked questions

How do I add Zambo MCP to Gemini CLI?

Open settings.json in your Gemini config folder, usually ~/.gemini/settings.json, and add a zambo entry under mcpServers with httpUrl set to https://zambo.dev/mcp. Save and start a new Gemini CLI session. Zambo then appears in the MCP list with 153 tools in total and 35 on the default surface.

Why does the Gemini CLI config use httpUrl?

Gemini CLI uses httpUrl for a remote MCP server reached over HTTP, and url fields in some other clients mean the same thing under a different name. Using the wrong field name is the most common reason a saved config produces no server at all. Keep the address itself exactly https://zambo.dev/mcp.

How do I verify Zambo is connected in Gemini CLI?

Run the MCP listing inside a fresh session and look for zambo in a connected state with tools discovered, then run one small call and open the receipt link in the result. Pasting that receipt ID into zambo.dev/verify and getting a match confirms the full path from Gemini CLI to a checkable record is working.

What do I get once Zambo is connected to Gemini CLI?

Gemini CLI gains Zambo tools for prices, web checks, lead work, memory, handover, and more, and every tool call returns a public receipt page. Memory saved through Zambo is stored server-side, so context saved in Gemini CLI can be recalled later in Claude, Cursor, ChatGPT, or Grok when they are connected to the same Zambo account.

How much does Zambo cost in Gemini CLI?

You can start on the free tier. A Day Pass costs $0.99 one time for 24 hours of full use. The Zambo Pass is $29 a month or $290 a year, and $19 a month for $ZAMBO holders. Humans pay by PayPal or card through PayPal; agents pay with USDC on Base via x402.
