Unmeasured means there is not enough evidence to decide. How these checks work
Start using OpenRepro ledger
Choose your client, copy the configuration, then enable the server in your client’s MCP settings.
Run this command in your terminal, then restart Claude Code.

Look up one paper in the OpenRepro ledger and return its re-run outcome with its qualifiers (such as a broad bound or a check that missed), how many agent-designated controls were excluded and how many gates the test had (when it has any), how many headline claims held, the assurance level, and links to the report and evidence. Matches arXiv IDs, DOIs, URLs, titles, short names and aliases. With no exact match it returns close matches when there are any, and says the paper is not in the ledger only when there are none.
DiscoveredThe full public record for one paper: outcome and qualifiers, summary, assurance, the attempt history (released and superseded versions with reasons), every claim checked with the published value, the re-run value, the registered tolerance, the check kind and the verdict, plus evidence links.
DiscoveredThe log's final hash, the downloadable evidence bundle, the report's SHA-256 from the release manifest, and the one command that checks the bundle with only Python. The verifier checks log and artifact integrity and that the report names the log's head hash; it does not check the report's contents against the log.
DiscoveredFor a paper not yet in the ledger: returns a ready-to-send email link to OpenRepro with the request filled in. Nothing is sent or stored by this tool; the user sends the email if they want to.
DiscoveredSearch published re-runs by words in the title, authors, venue or field, optionally filtered by outcome or field. With no query, lists the whole ledger.
