Registry code: 9eae961589ad44c8

api record

Phở Research Tools check scholarly references against Crossref, PubMed and OpenAlex. verify_references checks a reference list, check_retractions looks up retraction and correction notices, search_papers finds real papers with resolvable identifiers, format_citations builds a bibliography, and prisma_flow_diagram draws a PRISMA 2020 diagram. Results are lookups in public databases, not opinions: likely_fabricated means the DOI is not registered or no matching record was found in these databases.

what callers paid

inferred, not observed

Access was read off the card rather than seen on the wire: inferred: the handshake, the tool list and a call without arguments went through with no key and no payment asked; no tool was run

_ what it can do 5 tools

5 never probed 0 of 5 classified

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

search_papers unknown never probed

Search PubMed and OpenAlex for real papers. Every result carries a DOI or PubMed ID that resolves, so nothing returned can be fabricated. Finds sources for a claim or a topic. Filters: publication year range, open-access only, study types, and the number of results. Retracted papers are left out by default. Preprints are included and marked `preprint: true` (not peer reviewed). Results are ranked by the databases' relevance, alternating between the two sources.

check_retractions unknown 39m ago
Check DOIs for retractions, expressions of concern and corrections, using Crossref (which includes Retraction Watch data). Status per DOI: retracted, concern, corrected, other_notice, no_notice (nothing on record), not_in_crossref, invalid_doi, rate_limited or lookup_failed (the DOI could not be checked, which is not a clean result). Works for a single paper or a whole reference list.

format_citations unknown 39m ago

Format references in a citation style (APA 7, MLA 9, Chicago author-date, Harvard, Vancouver, IEEE, AMA) or export them as BibTeX, RIS or CSL-JSON. By default every reference is first verified against Crossref, PubMed and OpenAlex, and verified references are formatted from the database record, so wrong years, pages or author names in the input are corrected. References that could not be verified are formatted exactly as written and flagged in `entries[].warnings`. Returns the bibliography and, for text and html output, the matching in-text citation for each reference.

prisma_flow_diagram unknown 39m ago

Draw a PRISMA 2020 flow diagram for a new systematic review from the record counts, as a PNG image plus an SVG and download links. Give the counts you have; boxes that follow arithmetically from others are filled in and marked as derived. The tool checks that the numbers add up (records identified minus removed equals screened, and so on) and returns a warning naming each box that does not, with the value it should have. The diagram always shows the numbers exactly as given. Add `otherMethods` counts to draw the second column (websites, organisations, citation searching).

verify_references unknown never probed
Check every reference in a list against Crossref, PubMed and OpenAlex and report, for each one, whether the paper really exists and whether the details are right. Works on lists written by a person or generated by an AI model. Input: a pasted reference list in any common style (APA, Vancouver, numbered, mixed), BibTeX, RIS, CSL-JSON, or one DOI per line. Each reference gets exactly one status: verified, verified_with_corrections (real paper, some details wrong; corrected metadata included), likely_fabricated (no such paper exists), not_found (could not be confirmed either way), retracted, or ambiguous (several papers fit). likely_fabricated, not_found and ambiguous mean the reference could not be confirmed as a real paper; retracted means the paper exists but has been withdrawn. At most 50 references per call.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 9eae961589ad44c8.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/9eae961589ad44c8/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

[![measured by brick.blue](https://brick.blue/api/v1/agents/9eae961589ad44c8/badge.svg)](https://brick.blue/agent/9eae961589ad44c8?ref=badge)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we know

card completeness

90%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
