Pith (pith.science) machine-reviews new scientific papers and publishes for each a verdict, novelty and correctness scores, the core claim, the weakest assumption, and a falsifier: the observation that would settle the claim. For a specific paper, route by the requested information: use analyze_paper_claims for what it asserts, its premises, logical dependencies, argument structure, or reasoning; use get_paper_falsifier for a test or result that could disprove it; use get_review for Pith's overall evaluation, scores, and summary. All three accept an arXiv id or URL, DOI, or Pith Number. For a…

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

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.
record_coverage reads open 1h ago
Sources read and levels run for one paper's record, or the number of stored records by tier. Call before treating an empty result as a finding: an empty list means nothing in the examined scope matched.
{ "type": "object", "title": "record_coverageArguments", "properties": { "arxiv_id": { "type": "string", "title": "Arxiv Id", "default": "", "description": "One paper, or empty for the whole record store." } } }arguments 12 lineslatest_reviews reads open 1h ago
The papers Pith reviewed most recently, newest first. Call this when the user asks what is new, notable, or recently reviewed in a field or overall. days caps how far back to look (max 90).
{ "type": "object", "title": "latest_reviewsArguments", "properties": { "days": { "type": "integer", "title": "Days", "default": 7 }, "limit": { "type": "integer", "title": "Limit", "default": 10 }, "category": { "anyOf": [ { "type": "string" }, { "type": "null" } ], "title": "Category", "default": null, "description": "Field to filter by: an arXiv archive ('cond-mat'), a full category ('cond-mat.str-el'), or a plain field name like 'condensed matter' or 'machine learning'; omit for all fields." } } }arguments 29 linespaper_bridge reads unknown never probed
Whether either paper cites the other, the resolved works both cite (on or off arXiv), and the papers that cite both.
{ "type": "object", "title": "paper_bridgeArguments", "required": [ "a", "b" ], "properties": { "a": { "type": "string", "title": "A", "description": "Any form the user gave: bare arXiv id (2401.00001), arXiv abs/pdf URL, DOI or doi.org URL, or Pith Number." }, "b": { "type": "string", "title": "B", "description": "Any form the user gave: bare arXiv id (2401.00001), arXiv abs/pdf URL, DOI or doi.org URL, or Pith Number." }, "limit": { "type": "integer", "title": "Limit", "default": 12, "maximum": 40, "minimum": 1, "description": "Shared graph neighbors per side. 1 to 40." } } }arguments 28 linesget_review reads unknown never probed
Pith's review of one specific paper, in one call: the verdict, confidence, novelty and correctness scores, one-line summary, weakest assumption, and the paper's argument as short labeled statements (premise, machinery, core claim, falsifier) already extracted, so the paper's premises and logical structure can be stated without reading the PDF. Use this for any question about a specific paper: what it asserts, what it assumes, how the argument runs, how sound it is, or what Pith concluded. Accepts an arXiv id or URL, DOI, or Pith Number.
{ "type": "object", "title": "get_reviewArguments", "required": [ "arxiv_id" ], "properties": { "arxiv_id": { "type": "string", "title": "Arxiv Id", "description": "Any form the user gave: bare arXiv id (2401.00001), arXiv abs/pdf URL, DOI or doi.org URL, or Pith Number." } } }arguments 14 linessearch_papers reads unknown never probed
Search Pith-reviewed papers by title and abstract. Call this when the user names a research topic, phenomenon, method, or paper title without an identifier, or asks whether Pith has reviewed anything on a subject. Each result carries the paper's verdict, summary, and review link.
{ "type": "object", "title": "search_papersArguments", "required": [ "query" ], "properties": { "limit": { "type": "integer", "title": "Limit", "default": 10 }, "query": { "type": "string", "title": "Query", "description": "Topic, phenomenon, method, or paper title in plain words." } } }arguments 19 linesanalyze_paper_claims reads unknown never probed
The structured argument of one specific paper: what it actually asserts, the premises it assumes, the machinery connecting those premises to the claim, and the falsifier, as short labeled statements in argument order (premise, machinery, claim, falsifier). Use this for requests about a paper's claims, premises, assumptions, reasoning, logical dependencies, logical structure, argument structure, or conclusion. Each entry includes its text, role, type, and status.
{ "type": "object", "title": "analyze_paper_claimsArguments", "required": [ "arxiv_id" ], "properties": { "arxiv_id": { "type": "string", "title": "Arxiv Id", "description": "Any form the user gave: bare arXiv id (2401.00001), arXiv abs/pdf URL, DOI or doi.org URL, or Pith Number." } } }arguments 14 linesget_claims reads unknown never probed
Alias of analyze_paper_claims: the same ledger of what the paper asserts, its premises, machinery, and falsifier, in argument order.
{ "type": "object", "title": "get_claimsArguments", "required": [ "arxiv_id" ], "properties": { "arxiv_id": { "type": "string", "title": "Arxiv Id", "description": "Any form the user gave: bare arXiv id (2401.00001), arXiv abs/pdf URL, DOI or doi.org URL, or Pith Number." } } }arguments 14 linessearch_claims reads unknown never probed
Full-text search over every scientific claim Pith has extracted, across all reviewed papers. Call this when the user asks who claims something, whether a claim appears in the recent literature, or what evidence bears on a statement. Returns each matching claim with its paper, verdict, and review link.
{ "type": "object", "title": "search_claimsArguments", "required": [ "query" ], "properties": { "limit": { "type": "integer", "title": "Limit", "default": 10 }, "query": { "type": "string", "title": "Query", "description": "The claim or statement to look for, in plain words." } } }arguments 19 linesget_paper_falsifier reads unknown never probed
The falsifier for one specific paper's core claim: the concrete observation, experiment, or computation that would settle or disprove it, plus how many people are watching for that result. Use this when the user asks what would falsify the paper, prove it wrong, test its central claim, settle the claim, or show that the conclusion fails.
{ "type": "object", "title": "get_paper_falsifierArguments", "required": [ "arxiv_id" ], "properties": { "arxiv_id": { "type": "string", "title": "Arxiv Id", "description": "Any form the user gave: bare arXiv id (2401.00001), arXiv abs/pdf URL, DOI or doi.org URL, or Pith Number." } } }arguments 14 linesget_falsifier reads unknown never probed
Alias of get_paper_falsifier: the same falsifier and watcher count.
{ "type": "object", "title": "get_falsifierArguments", "required": [ "arxiv_id" ], "properties": { "arxiv_id": { "type": "string", "title": "Arxiv Id", "description": "Any form the user gave: bare arXiv id (2401.00001), arXiv abs/pdf URL, DOI or doi.org URL, or Pith Number." } } }arguments 14 linesget_signed_reviews reads unknown never probed
Published human signed reviews of one paper: reviewer identity, axis deltas against the machine review, claim verdicts, defects, predictions, and who paid. Call this when the user asks what human experts said about a paper, on top of the machine review.
{ "type": "object", "title": "get_signed_reviewsArguments", "required": [ "arxiv_id" ], "properties": { "arxiv_id": { "type": "string", "title": "Arxiv Id", "description": "Any form the user gave: bare arXiv id (2401.00001), arXiv abs/pdf URL, DOI or doi.org URL, or Pith Number." } } }arguments 14 linesget_reviewer_record reads unknown never probed
A reviewer's published signed reviews and, when present, their calibration record (Brier score, open predictions, positivity skew). Call this when the user asks about a named Pith reviewer or how trustworthy a reviewer's track record is.
{ "type": "object", "title": "get_reviewer_recordArguments", "required": [ "handle" ], "properties": { "handle": { "type": "string", "title": "Handle" } } }arguments 13 linesget_record reads unknown never probed
The compiled record of one paper: the authors' own sentences, arranged with typed labels. It carries the main claim in the authors' words, each abstract sentence's role, results with the qualifications the authors state beside them, the conditions of the study, measurements with where they appear, the arXiv listing abstract compared with the manuscript's abstract, resources including what is not stated, the authors' own limitations, how the paper uses its references, and what was and was not examined. No sentence in it was written by a model; every label carries its probability. Use this for what a paper states and under what conditions, including papers Pith has not reviewed, where get_review reports no review. Accepts an arXiv id or URL, DOI, or Pith Number.
{ "type": "object", "title": "get_recordArguments", "required": [ "arxiv_id" ], "properties": { "arxiv_id": { "type": "string", "title": "Arxiv Id", "description": "Any form the user gave: bare arXiv id (2401.00001), arXiv abs/pdf URL, DOI or doi.org URL, or Pith Number." } } }arguments 14 linesresolve_paper reads unknown never probed
Turn a pasted arXiv id, arXiv URL, DOI, or Pith Number into the arXiv id the other tools key on. ``resolved`` is false when the input did not become an arXiv id.
{ "type": "object", "title": "resolve_paperArguments", "required": [ "reference" ], "properties": { "reference": { "type": "string", "title": "Reference", "description": "Any form the user gave: bare arXiv id (2401.00001), arXiv abs/pdf URL, DOI or doi.org URL, or Pith Number." } } }arguments 14 linespaper_packet reads unknown never probed
One paper's compiled record, small enough to hold beside others: the main claim and contribution in the authors' words, each abstract sentence with its role and probability, paper-level labels, and, for full-text records, conditions, measurements, results and limitations, with totals so a capped list is not mistaken for the whole paper.
{ "type": "object", "title": "paper_packetArguments", "required": [ "arxiv_id" ], "properties": { "limit": { "type": "integer", "title": "Limit", "default": 8, "maximum": 20, "minimum": 1, "description": "Items per list. 1 to 20." }, "arxiv_id": { "type": "string", "title": "Arxiv Id", "description": "Any form the user gave: bare arXiv id (2401.00001), arXiv abs/pdf URL, DOI or doi.org URL, or Pith Number." } } }arguments 22 linescitation_neighbors reads unknown never probed
One hop from a paper: every reference entry with its resolved work identity, the papers that cite it, and, where a record exists, the citing sentences with their labeled intent. An edge means the paper names the other work, not that the work supports the citing claim.
{ "type": "object", "title": "citation_neighborsArguments", "required": [ "arxiv_id" ], "properties": { "limit": { "type": "integer", "title": "Limit", "default": 12, "maximum": 40, "minimum": 1, "description": "Graph rows per side. 1 to 40." }, "arxiv_id": { "type": "string", "title": "Arxiv Id", "description": "Any form the user gave: bare arXiv id (2401.00001), arXiv abs/pdf URL, DOI or doi.org URL, or Pith Number." }, "direction": { "type": "string", "title": "Direction", "default": "both", "description": "out: works this paper cites. in: papers that cite it. both." } } }arguments 28 linesfind_passages reads unknown never probed
Author sentences Jev labeled with one role, across every stored record, each with its probability and paper. Abstract-tier records cover limitation, result and main_claim; full-text records add condition, citation and measurement.
{ "type": "object", "title": "find_passagesArguments", "required": [ "role" ], "properties": { "role": { "type": "string", "title": "Role", "description": "limitation, condition, result, main_claim, citation, or measurement." }, "limit": { "type": "integer", "title": "Limit", "default": 20, "maximum": 50, "minimum": 1, "description": "1 to 50." }, "query": { "type": "string", "title": "Query", "default": "", "description": "Words to match in the author's sentence. Empty returns the role." }, "arxiv_id": { "type": "string", "title": "Arxiv Id", "default": "", "description": "One paper, or empty for every stored record." } } }arguments 34 lines
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.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.
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.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
