For teams shipping health AI

Your AI cites a page.
That page cites a review.
The review rests on a retracted trial.

MoolTrace builds a citation graph in FalkorDB from the answer, through each page and review, down to the trials. It blocks the answer if a source it relies on was retracted, warns on an Expression of Concern, shows you the exact path, and drafts a fix.

A citation check passes all 35 Harvard nutrition pages.

MoolTrace flags 2, and I checked both by hand.

The fix

Harvard reviews the evidence at nutritionsource.hsph.harvard.edu/vitamin-d.

An earlier version of this answer cited the Harvard Nutrition Source page “Vitamin D”, which cites Avenell et al. 2014, which uses data from Ishida et al. 2004, a paper that was retracted in May 2025, so that source was removed.

  1. 1

    You give it an answer

    Paste a draft or the links it cites. Or let your agent call it over MCP.

  2. 2

    It builds the graph

    Every page gets resolved to the papers behind it (Crossref, OpenAlex, PubMed) and stored in FalkorDB as page, review and trial. Retractions and concerns hang off the papers they flag.

  3. 3

    It weighs every link

    A trial the review actually included counts fully. A passing mention barely counts. FalkorDB's shortest path search finds the strongest chain to a flagged paper.

  4. 4

    You get a verdict

    Don't ship, Review, Clear or Not checked. Always with the path and the sentence behind each hop.

  5. 5

    It fixes the answer

    Only the sentence that leaned on the bad source changes. Then it checks the answer again.

Track 01 · Agents that act on connected data

Works where answers get made.

Your agent checks itself.

The model picks the tools. The graph decides. Only tool output ships.

  1. check_answer · don't ship

    Walks page → review → trial in FalkorDB.

  2. explain_path · Harvard → Cochrane → Ishida

    Shows the exact chain and the sentence behind each hop.

  3. rewrite_answer · fixed, clear

    Removes the retracted source, then checks again.

Without MoolTrace · ships as written

Vitamin D helps prevent fractures in older adults. Harvard reviews the evidence at nutritionsource.hsph.harvard.edu/vitamin-d.

With MoolTrace · checked again: clear

Vitamin D helps prevent fractures in older adults (no checked source remains for this claim). An earlier version of this answer cited the Harvard Nutrition Source page “Vitamin D”, which cites Avenell et al. 2014, which uses data from Ishida et al. 2004, a paper that was retracted in May 2025, so that source was removed.
