Second Read v0.1.0
First release of Second Read: evidence-backed document review for Claude, as an MCP server.
Give it an article, a blog post or a design doc and it returns one report:
- Facts checked against the web. Each claim is researched (search, fetch, read; up to three rounds), and every "this is wrong" comes with the page and passage it relies on. Claims it cannot confirm are listed separately under "Could not verify".
- The strongest counter-case. A devil's advocate builds the best opposing argument from retrieved sources.
- Copy edits that keep your voice, and originality notes for sentences that closely match text online.
Install

Good to know
- Runs on your machine with your own keys. A review of a 700-word article takes about two minutes and roughly 150,000–180,000 tokens.
- On a small test of articles whose errors need looking up, it caught 13 of 19 planted wrong facts with a cited source for each, against 7 of 19 (no sources) for a single prompt. Details in the README.
