Automated README summary
Automatically summarized from the README on 14 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
A Chrome side-panel extension that discovers WebMCP tools on the current page and predicts which tool and arguments match the user's typed input, showing confidence and latency. Built for developers exploring agent-style tool calling in the browser.
How it uses Jev
Jev answers typed questions derived from tool schemas: a Choice over tool names, Choices over enums and small integer ranges, Nouls for booleans and optional fields, and Choices over spans of the user's words for free text. Answers become { name, args, confidence, per-argument detail } used by policy.js to auto-run, confirm, or mark incomplete.
Primitives:choicescorenoul
Technique worth stealing
Convert each tool schema into typed questions (Choice/Score/Noul) so tool selection and argument filling become one parallel prediction, not text generation.
Try it
Load unpacked in chrome://extensions, paste a TypeSafe key in settings, enable on a WebMCP site.
Model judgments from README excerpts
Project signals use repository metadata, an existing summary and the first 700 README characters, not the full project. “Not found” means not detected in that material; it does not establish absence. These are the original judgments with recorded models and dates, not source audits or run results.

Evidence
These signals use repository metadata, an existing summary and at most 700 cleaned README characters. ≥ 0.60 means reported in that excerpt; ≤ 0.40 means not found there. The middle band is inconclusive. None is a source-code audit or a test result. The runnable-tool question excludes research experiments; the recommendation question asks for a learning shortlist, not a quality verdict.
