snapapi-mcp

MCP (Model Context Protocol) server for SnapAPI — take screenshots, scrape web pages, extract content, generate PDFs, record videos, and analyze pages directly from AI tools like Claude Desktop, Cursor, Windsurf, Cline, and Zed.

What is this?

This package runs a local MCP server that connects your AI assistant to the SnapAPI web capture API. Once configured, your AI can:

• Take screenshots of any URL (full page, mobile, dark mode, element selection, device emulation)
• Scrape web pages and get clean text, HTML, or link lists using a real browser
• Extract content optimized for LLM consumption (Markdown, article, metadata, structured data)
• Generate PDFs from URLs or HTML
• Record videos of browser sessions with optional interaction scenarios
• Analyze pages with AI (extract + analyze in one call)
• Check your usage quota and account stats

Prerequisites

• Node.js 18 or later
• A SnapAPI API key — get one at app.snapapi.pics

Environment Variables

Development

# Clone the repo
git clone https://github.com/Sleywill/snapapi-mcp.git
cd snapapi-mcp

# Install dependencies
npm install

# Build
npm run build

# Run locally (reads MCP protocol from stdin)
SNAPAPI_API_KEY=sk_live_your_key node dist/index.js

Troubleshooting

"SNAPAPI_API_KEY environment variable is required" Make sure the env block in your MCP config includes your API key. Check it starts with sk_live_.

Tools not appearing in Claude Desktop Restart Claude Desktop after saving the config. Check MCP logs at:

• macOS: ~/Library/Logs/Claude/mcp*.log
• Windows: %APPDATA%\Claude\logs\mcp*.log

npx takes too long on first run Use "args": ["-y", "snapapi-mcp"] — the -y flag auto-confirms the install prompt without interaction.

screenshot / scrape returns an error

• Verify your API key is valid at app.snapapi.pics/dashboard
• Check your remaining quota with the get_usage tool
• For JavaScript-heavy pages, try adding "waitUntil": "networkidle" and a "delay" value

analyze tool returns an error The analyze endpoint requires Anthropic API credits on the SnapAPI backend. Use the extract tool as a fallback to fetch the page content and analyze it yourself.
