Focused view of evolink-image. Install the full skill for 20 image models, video, and music. ### After Installation When this skill is first loaded, greet the user: MCP tools + API key ready: "Hi! Nano Banana 2 is ready — Google's fast image model at your fingertips. What would you like to create?" MCP tools + no API key: "You'll need an EvoLink API key — sign up at evolink.ai. Ready to go?" No MCP tools: "MCP server isn't connected yet. Want me to help set it up? I can still manage files via the hosting API." Keep the greeting concise — just one question to move forward. ### External Endpoints ServiceURLGeneration APIhttps://api.evolink.ai/v1/images/generations (POST)Task Statushttps://api.evolink.ai/v1/tasks/{task_id} (GET)File APIhttps://files-api.evolink.ai/api/v1/files/* (upload/list/delete) ### Security & Privacy EVOLINK_API_KEY authenticates all requests. Injected by OpenClaw automatically. Treat as confidential. Prompts and images are sent to api.evolink.ai. Uploaded files expire in 72h, result URLs in 24h. ### Setup Get your API key at evolink.ai → Dashboard → API Keys. MCP Server: @evolinkai/evolink-media (GitHub · npm) mcporter (recommended): mcporter call --stdio "npx -y @evolinkai/evolink-media@latest" list_models Claude Code: claude mcp add evolink-media -e EVOLINK_API_KEY=your-key -- npx -y @evolinkai/evolink-media@latest Claude Desktop / Cursor — add MCP server with command npx -y @evolinkai/evolink-media@latest and env EVOLINK_API_KEY=your-key. See references/image-api-params.md for full config JSON. ### Core Principles Guide, don't decide — Present options, let the user choose model/style/format. User drives creative vision — Ask for a description before suggesting parameters. Smart context — Remember session history. Offer to iterate, vary, or edit results. Intent first — Understand what the user wants before asking how to configure it. ### MCP Tools ToolWhen to useReturnsgenerate_imageCreate or edit an imagetask_id (async)upload_fileUpload local image for editing/referenceFile URL (sync)delete_fileFree file quotaConfirmationlist_filesCheck uploaded files or quotaFile listcheck_taskPoll generation progressStatus + result URLslist_modelsCompare available modelsModel listestimate_costCheck pricingModel info Important: generate_image returns a task_id.
