Gemini CLI

One command.

gemini mcp add writes the config for you. Prefer editing ~/.gemini/settings.json? Gemini uses httpUrl instead of url.

Step 01

Run one command (or edit settings.json).

terminal, one line

gemini mcp add --scope user --transport http bankbridge https://bankbridge.money/api/mcp
# then run /mcp auth bankbridge in Gemini CLI

~/.gemini/settings.json

{
  "mcpServers": {
    "bankbridge": {
      "httpUrl": "https://bankbridge.money/api/mcp",
      "headers": {
        "Authorization": "Bearer bbk_your_api_key_here"
      }
    }
  }
}

Restart Gemini CLI after editing the config.

Step 02

Verify it works.

Restart Gemini, then ask:

Troubleshooting

Client connects but shows 0 tools.

Usually the client is caching an old config, or you're on a mode that doesn't expose tools (Ask/Edit vs Agent, for example).

Fix: Fully quit + relaunch the host app. In VS Code Copilot, switch to Agent mode.

401 Unauthorized on every call.

The API key is missing, typo'd, or got revoked. Check the Authorization header starts with `Bearer ` (note the space) and ends in a key you still own.

Fix: Paste a fresh key from Settings.

Tools return a NO_CONNECTIONS warning.

You haven't linked a bank yet.

Fix: Visit Connect a bank . The bank-connect flow opens automatically, ~30 seconds.
