Is Alumnium Worth It?
Alumnium is a free ai agent infrastructure tool that offers 5 key features including Three high-level MCP tools — do(), get(), check() — instead of raw browser primitives, Keeps accessibility trees and screenshots out of the main agent's context window, 98.5% on WebVoyager with Claude Code and Selenium, above the prior 97.1% SOTA. Alumnium is an open-source MCP server that gives a general-purpose coding agent high-level browsing rather than raw browser primitives, and it has the benchmark result to argue the design is right. Used with Claude Code and Selenium it scores 98.5% on WebVoyager, above the previous published state of the art of 97.1%, and because the project is open source it publishes the full evidence — session transcripts, screenshots and evaluator responses at webvoyager.alumnium.ai — plus a fork of the benchmark with the code to reproduce it. The architectural argument is the useful part for anyone choosing a browser tool. One approach is a fully autonomous browser agent that takes a goal and returns an answer as a black box, separate from whatever else your agent is doing. The other is exposing raw click, type and navigate primitives, which gives the agent full control but floods the context window with accessibility trees and screenshots on every state change, derailing the main agent from its actual job and triggering compaction. Alumnium sits between the two: it exposes a small set of high-level tools — do(), get() and check() — that compress the knowledge of how to browse into three calls, so the main agent keeps its context for the task it was actually given. It works with Selenium and integrates as an MCP server.
