Category & Scope
Tools & Capabilities Breakdown
Aethyn Browser Mcp Tools (10)
aethyn_launch_browser
Launch a local Chromium routed through a residential proxy exit in a chosen country (and city/state on the Elite tier). Returns a session_id the other aethyn_* tools use. Each session is one sticky identity — a pinned exit IP for the whole task.
aethyn_navigate
Navigate the session's browser to a URL and wait for load. Returns the HTTP status, final URL, and page title — read the page with aethyn_get_content to judge the response yourself. Public data only — respect robots.txt, rate limits, and each site's terms.
aethyn_get_content
Return the current page's content cleaned for reading (markdown by default). Use after navigating to extract data.
aethyn_snapshot
Return a structured accessibility snapshot (roles, names, and [ref=..] handles) of the page. Pass those refs to aethyn_click / aethyn_type. No screenshots needed.
aethyn_click
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Aethyn Browser Mcp is categorized under Browser Automation and uses a local stdio subprocess. In contrast, Intercept Mcp belongs to Browser Automation using local stdio subprocess. Select Aethyn Browser Mcp when you need capabilities focused on browser automation and Intercept Mcp when you require tools for browser automation.
Click an element. Prefer a 'ref' from aethyn_snapshot (e.g. 'e12'); or pass a 'selector' (CSS, or Playwright role=/text= engine).
aethyn_type
Type text into an input. Prefer a 'ref' from aethyn_snapshot; or a 'selector'. Set submit:true to press Enter after.
aethyn_check_exit_ip
Fetch IP info THROUGH the session's proxy so you can verify the exit country/city actually landed before trusting the page. Returns ip, country, city, org/ASN, and a best-effort is_residential flag.
aethyn_new_identity
Rotate the session to a fresh residential exit (new IP, same country) and clear cookies. Use between independent tasks or after a soft-block.
aethyn_close
Close the session's browser context and free memory. Call this when a task is done.
aethyn_list_countries
List available exit countries (and Elite-tier cities where known). Discover geo options at runtime before launching.
Intercept Mcp Tools (5)
fetch
Fetch a URL and return its content as clean markdown. Handles Twitter/X tweets, YouTube videos (with transcripts), arXiv papers, PDFs, Wikipedia articles, and GitHub repos/files/issues/PRs/releases directly. Direct image URLs (png/jpeg/gif/webp) are returned as an image block for vision. Otherwise checks a shared cache, then falls back through a multi-tier chain: Jina Reader, web archives (Wayback, archive.ph, Arquivo.pt), raw fetch, RSS, CrossRef, Semantic Scholar, HackerNews, Reddit, OG meta. Long pages are truncated at maxLength characters — paginate with startIndex. Results are cached for the session; pass noCache to force a live fetch.
fetch_batch
Fetch up to 10 URLs in parallel and return each as clean markdown. Same handler/fallback chain as the fetch tool, with a smaller per-URL length budget. Use after a search to pull several sources in one call.
research
Search the web and fetch the content of the top results in one call. Returns the full content of each result as markdown, ready to summarize or compare. Use this instead of separate search + fetch calls when researching a topic.
search
Search the web and return results. Uses Brave Search API if BRAVE_API_KEY is set, otherwise falls back to SearXNG and then DuckDuckGo. Supports domain filtering (site), freshness, and pagination (page).
extract
Extract specific values from a web page as JSON instead of markdown prose. Provide CSS selectors to pull named fields (text or an attribute, first match or all), and/or set tables:true to convert every HTML table to arrays of row objects. Use this when you need particular data (prices, lists, specs, tabular data) rather than the whole page. Honors per-domain auth and proxies.
