BananaBanana MCP Server

An MCP server for image, video, and speech generation — Google Nano Banana, Veo, Omni, and Gemini TTS models — that lets any MCP client (Claude Code, Claude Desktop, Cursor, and more) create media pay-as-you-go with crypto payments and no subscription.

Endpoint: https://bananabanana.pro/api/mcp (streamable HTTP)
Auth: OAuth 2.1 (sign in — nothing to copy) or Authorization: Bearer bb_live_… — create a key
Website: https://bananabanana.pro/?utm_source=mcp_readme&utm_medium=mcp_catalog · Docs & live example: https://bananabanana.pro/mcp?utm_source=mcp_readme&utm_medium=mcp_catalog

Generate images from $0.03, videos from $0.10, and speech for $0.01 per started 200 transcript characters, billed from an account balance you top up with crypto. Cost quotes before every expensive call, automatic refunds on failure, and one shared image/video history with the website.

Quick Start

OAuth is the primary connection path. API keys remain available for clients without OAuth and for scripts or CI:

OAuth 2.1 (claude.ai, Claude Desktop, Claude mobile, Claude Code, MCP Inspector): add a custom connector with the URL above, press Connect and approve access. No key to copy. See docs/authentication.md.
API key (Cursor, VS Code, Windsurf, Codex, scripts, CI): create a key in your profile — https://bananabanana.pro/profile?utm_source=mcp_readme&utm_medium=mcp_catalog, API Keys section — and put it in the client config as shown below.

claude.ai / Claude Desktop / mobile (OAuth)

Settings → Connectors → Add custom connector
URL: https://bananabanana.pro/api/mcp
→ Add → Connect → approve access on bananabanana.pro

Claude Code

# OAuth — no key; run /mcp inside Claude Code and choose "Authenticate"
claude mcp add --transport http bananabanana https://bananabanana.pro/api/mcp

# API-key fallback for non-interactive use
claude mcp add --transport http bananabanana https://bananabanana.pro/api/mcp \
  --header "Authorization: Bearer bb_live_YOUR_KEY"

Claude Desktop

Use Settings → Connectors → Add custom connector and enter https://bananabanana.pro/api/mcp, then press Connect and approve access. If your Desktop build uses claude_desktop_config.json, the OAuth-capable mcp-remote bridge requires Node.js:

{
  "mcpServers": {
    "bananabanana": {
      "command": "npx",
      "args": [
        "-y", "mcp-remote", "https://bananabanana.pro/api/mcp"
      ]
    }
  }
}

The bridge opens the OAuth sign-in flow on first use. See docs/authentication.md for the API-key fallback.

Other clients (Cursor, VS Code, Windsurf)

Cursor — ~/.cursor/mcp.json (global) or .cursor/mcp.json (project):

{
  "mcpServers": {
    "bananabanana": {
      "url": "https://bananabanana.pro/api/mcp",
      "headers": { "Authorization": "Bearer bb_live_YOUR_KEY" }
    }
  }
}

VS Code — .vscode/mcp.json (stores the key as an encrypted prompt):

{
  "servers": {
    "bananabanana": {
      "type": "http",
      "url": "https://bananabanana.pro/api/mcp",
      "headers": { "Authorization": "Bearer ${input:bb-api-key}" }
    }
  },
  "inputs": [
    { "type": "promptString", "id": "bb-api-key", "description": "BananaBanana API key (bb_live_…)", "password": true }
  ]
}

Windsurf — ~/.codeium/windsurf/mcp_config.json:

{
  "mcpServers": {
    "bananabanana": {
      "serverUrl": "https://bananabanana.pro/api/mcp",
      "headers": { "Authorization": "Bearer bb_live_YOUR_KEY" }
    }
  }
}

Ready-to-copy configs live in examples/. Once connected, ask your agent to run list_models (free) — it returns the live model list and prices. An OAuth user can also ask the agent to call top_up; the returned browser link grants deposit-only access without exposing the full profile.

No MCP client? The server is plain JSON-RPC over HTTPS — call it from curl, Python or TypeScript with no SDK: examples/no-sdk.md (runnable scripts: generate.py, generate.mjs).

Tools

Ten tools; the read-only and account-access tools are free. Full reference in docs/tools.md.

Tool	What it does	Key parameters
`list_models`	List models with live USD prices, resolutions, durations, constraints. Free.	—
`get_account`	Balance, key name, daily cap, spend today. Free.	—
`top_up`	Return a balance top-up link. OAuth gets a one-time deposit-only link; API-key users get the profile URL. Free.	—
`generate_image`	Text-to-image (Nano Banana 2 Lite / 2 / Pro), up to 4K, 1–4 variants. Lite is the default; choose Nano Banana 2 for resolutions above 1024. Returns a `job_id`.	`prompt`, `model`, `aspect_ratio`, `resolution`, `number_of_images`, `confirm_cost`
`edit_image`	Multi-turn edit of a finished image by text instruction.	`source_generation_id`, `prompt`, `model`, `resolution`
`generate_video`	Video (Veo 3.1 family or Omni Flash), optionally from a start frame and reference images. Always quotes first. Returns a `job_id`.	`prompt`, `model`, `duration`, `resolution`, `with_audio`, `first_frame`, `reference_images`, `confirm_cost`
`edit_video`	Video-to-video editing on Omni Flash: restyle, replace objects, relight an existing clip. Always quotes first.	`prompt`, `source_generation_id` or `video_url`, `duration`, `audio_prompt`, `confirm_cost`
`generate_speech`	Gemini 3.1 Flash TTS speech: one speaker or a two-speaker dialogue. Returns a hosted WAV URL synchronously.	`text`, `voice`, `language_code`, `style`, `speakers`
`get_result`	Poll a job; returns hosted media URLs (24 h) + cost/balance. Free.	`job_id`, `wait_seconds`
`list_generations`	Recent account history (shared with the website). Free.	`limit`, `type`, `status`

Image and video generation is async: generation/editing calls return a job_id; poll get_result for the media. generate_speech is synchronous and returns its WAV URL directly. generate_video, edit_video and multi-image generate_image quote first and charge nothing until you repeat the call with confirm_cost.

Pricing

Pay-as-you-go in USD: per image, per Veo clip, per second for Omni Flash, and per started 200 transcript characters for speech. Live numbers come from list_models; full tables in docs/pricing.md.

Model	Type	Price
`nano-banana-2-lite`	Image (1024)	$0.03
`nano-banana-2`	Image (512→4096)	$0.03 – $0.13
`nano-banana-pro`	Image (1024→4096)	$0.11 – $0.20
`veo-3.1-lite`	Video (720p/1080p; 4, 6 or 8 s)	$0.10 – $0.56
`veo-3.1-fast`	Video (up to 4K; 4, 6 or 8 s)	$0.35 – $2.60
`veo-3.1`	Video (up to 4K; 4, 6 or 8 s)	$0.70 – $4.40
`omni-flash`	Video (720p, sound, 3–10 s)	$0.10 / s ($0.30 – $1.00)
`gemini-3.1-flash-tts-preview`	Speech (WAV)	$0.01 / started 200 transcript characters

Images cost $0.03–$0.20 each; video costs $0.10–$4.40 per clip, with Omni Flash billed at $0.10/s. Veo generation accepts 4, 6 or 8 seconds; the 7-second prices returned by list_models are for extension jobs, not a selectable generate_video duration. Free tools: list_models, get_account, top_up, get_result, list_generations. Failed and content-filtered generations are refunded automatically.

Top-up bonuses can lower the effective cost: deposits of $50+ receive 5% extra balance, deposits of $100+ receive 10%, and an active partner promo code adds another 10%. Bonuses stack. The table shows nominal generation charges; effective out-of-pocket cost depends on the top-up bonus. Promo codes require a normal signed-in profile and are intentionally unavailable in an OAuth deposit-only session.

Why this instead of a subscription service

You pay for what you generate — nothing else. No monthly fee, no seats, no credits that expire. A quiet month costs $0; the balance you top up is the only spend.
The agent sees the price before it spends. list_models returns live prices, and video / batch calls return a quote and charge nothing until confirmed — so an agent can't run up a surprise bill.
Failures don't cost you. Upstream errors and content-filter rejections are refunded automatically; optional per-key daily caps and idempotency_key bound the downside further.
Crypto top-ups, no card required. Deposits of $50+ / $100+ receive 5% / 10% extra balance, and an active partner promo code adds another 10%. One balance and one image/video history are shared between MCP and the website.
