Crate stygian_mcp 

Unified MCP (Model Context Protocol) aggregator for Stygian.

Merges the tool surfaces of stygian-graph, stygian-browser, and stygian-proxy into a single MCP server. An LLM agent connecting to this server can scrape URLs, run pipeline DAGs, automate browsers, manage proxy pools, and combine all three capabilities — without needing to connect to three separate processes.

Tools are prefixed by crate: graph_scrape, browser_acquire, proxy_add. The aggregator itself adds two cross-crate tools:

Tool	Description
scrape_proxied	HTTP scrape routed through the proxy pool
browser_proxied	Browser session with proxy from the pool
