//! 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.
//!
//! ## Architecture

//! ```
//!
//! 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 |
