Open-source MCP server Shadow Web turns local browsers into 20+ agent tools
A Reddit post introduces Shadow Web, a Python MCP server for AI agents that can browse pages, interact with elements, and extract structured data without relying on cloud APIs.
What it does
- Runs locally with Playwright
- Flattens Shadow DOM into an Action Map
- Uses SchemaSnap to turn tables, forms, and lists into JSON
- Builds token-aware content outlines for long pages
- Includes web search, click/fill, snapshot, form-filling, and page-compression tools
Claimed gains
- Wikipedia page: 99K tokens → 16K
- GitHub Trending: 168K tokens → 38K
The author says the tool was built for competitor monitoring and data extraction, but asks what other agent workflows could benefit from a no-cloud browser stack.
