Add to opencode.json.

(Or create a project-local opencode.json — project overrides global.)

{
  "$schema": "https://opencode.ai/config.json",
  "mcp": {
    "bankbridge": {
      "type": "remote",
      "url": "https://bankbridge.money/api/mcp",
      "enabled": true,
      "oauth": false,
      "headers": {
        "Authorization": "Bearer ldgr_your_api_key_here"
      }
    }
  }
}

Replace ldgr_your_api_key_here with a real key from your keys page. The "oauth": false line tells opencode not to attempt an OAuth browser flow on 401 — we use a static bearer token.

Start or restart opencode. Run opencode mcp list to confirm bankbridge is listed and ready.
