"Free image analysis tool" matching MCP connectors:

Social media analytics, video analysis, and competitor intel for any MCP-compatible AI agent.

Generate images and video from any MCP client — Claude Code, Claude Desktop, Cursor, VS Code, Windsurf. Models: Nano Banana 2 / 2 Lite / Pro for images (up to 4K), Veo 3.1 / Fast / Lite for video (4/6/8 s, up to 4K, optional native audio), and Omni Flash (720p with sound). Strictly pay-as-you-go: top up a balance, pay per generated item. Images from $0.03, video from $0.10. No subscription, no seats, no expiring credits — a month with no generations costs $0. Top up with crypto or Telegram Stars; no card required. Built for agents, not just humans. Expensive calls return a cost quote and charge nothing until the agent repeats them with confirm_cost, so an agent cannot run up a surprise bill. Failed generations and content-filter rejections are refunded automatically. Optional daily spend caps per API key. Seven tools, four of them free: list_models, get_account, get_result and list_generations cost nothing; only generate_image, edit_image and generate_video are billed. Nothing to install — hosted remote endpoint, no local runtime, no Google API keys needed. Docs: https://bananabanana.pro/mcp

Free sandbox (Display mode): no PHI, no BAA. Not medical advice.

Design, save, and run outcome-aligned AI workflows and verifiers, with reliable image output.

This tool empowers MCP-compatible clients (like Cursor and Claude Desktop) with professional-grade capabilities for financial data extraction, and report analysis.
