Levirge Search — web research your agent can actually reach

Levirge Search — web research your agent can actually reach

Search the web and read the sources, with citations.

Levirge Search is a hosted MCP server for research: unfilteredweb search, and a URL fetch where pages that need JavaScript or refuse plain requests are opened ina full browser — so your agent can open the original source and cite it.

Install (2 minutes)

Claude Code:

claude plugin marketplace add levirge/search
claude plugin install levirge-search@levirge-search

Then run /mcp in a session and sign in.

Codex CLI:

codex plugin add levirge/search

Any other MCP client — point it at https://search.levirge.com/mcp. It answers a standard OAuthchallenge, so clients that speak MCP authorization discover sign-in on their own; no token to paste.

Update

plugin install won't upgrade, and the desktop "Update" button stays greyed out until the app'smarketplace cache is refreshed (the dialog has no refresh button). From the CLI — it shares the samestore as the desktop app:

claude plugin marketplace update levirge-search
claude plugin update levirge-search@levirge-search

Then restart the client — the plugin registry and MCP tool schemas are cached at startup, so newcommands and tool params don't appear until then.

What you get

• Search that isn't a summary — search runs SearXNG across engines and returns real resultsets, not one provider's ranking.
• Fetch that opens the page — fetch takes any URL, including agent-constructed API endpoints;pages that need JavaScript or refuse plain requests are opened in a full browser. One tool, bothroutes.
• Background scans — fetch_async queues up to 200 URLs through the same routing and paces themper-domain; collect with fetch_results instead of blocking.
• A stealth registry that learns — domains that needed the full browser are remembered pertenant, so the second visit skips the retry (/levirge-search:stealth).
• A failure queue worth reading — stealth_failures lists domains where the stealth browseritself got blocked, including regressions on domains that used to work.
• A skill that fires on refusal — web-fetch-fallback teaches the agent to reach for this whenits primary fetch says "blocked", instead of silently falling back to search.
