Weavy MCP Server

MCP server for automating Weavy.ai creative workflows via Playwright browser automation.

What It Does

This server gives Claude Code direct control over Weavy's node-based canvas. It launches a Chromium browser, connects to your Weavy account, and exposes tools for building creative pipelines programmatically.

Tools

Tool	Description
`weavy_screenshot`	Capture current canvas state
`weavy_list_projects`	List all projects from dashboard
`weavy_open_project`	Open existing project or create new
`weavy_add_node`	Add any node type to canvas (models, editing, text, helpers)
`weavy_remove_node`	Remove a node from canvas
`weavy_get_canvas_state`	List all visible nodes with positions
`weavy_set_prompt`	Enter text into a Prompt node
`weavy_configure_node`	Set node parameters (aspect ratio, model settings, etc.)
`weavy_import_file`	Upload a file via Import node
`weavy_connect_nodes`	Connect output of one node to input of another
`weavy_disconnect_nodes`	Remove a connection between nodes
`weavy_run_node`	Execute a generative node and wait for completion
`weavy_export`	Download output via Export node
`weavy_create_app`	Publish workflow as a Design App

Setup

cd ~/.claude/mcp-servers/weavy-mcp
npm install
npx playwright install chromium

Add to ~/.claude/mcp.json:

{
  "mcpServers": {
    "weavy": {
      "command": "node",
      "args": ["/path/to/weavy-mcp/server.js"]
    }
  }
}

Authentication

No API keys needed. The server uses a persistent Chromium profile at .browser-data/. On first use, it opens a browser window — log into Weavy manually once, and the session persists.

Companion Skill

Pair with the weavy-architect skill (~/.claude/skills/weavy-architect/) for guided workflow design with model selection, node graph planning, and credit optimization.
