## Description
Read-only MCP over an agentic SLR workspace with per-claim citation verification

## Claude Desktop Quick Installation
Heuristic fallback — verify the package name and runner against the repository README before running it. Uses `npx` (confidence: low):

```json
"mcpServers": {
  "thoth": {
    "command": "npx",
    "args": ["-y","thoth"]
  }
}

# Thoth

**Agentic systematic literature reviews — with every citation checked against the source.**

*Named for Thoth, ancient Egypt's ibis-headed god of writing and scribes.*

## What is Thoth?

Systematic literature reviews are slow to write — and when you ask an LLM to write
one, it confidently invents citations and statistics that aren't in any paper.

**Thoth does both halves and checks its own work.** Give it a research question and
it discovers relevant papers, reads them, drafts an evidence-grounded review — then
runs a verification pass (`cite_check`) that compares **every cited claim against the
source paper** and flags anything unsupported *before you read the draft*. The result
is a review with a critic score, a citation-faithfulness percentage, and a per-claim
audit you can trust.

It runs as a polished web app, a public eval dashboard, and an authenticated MCP
server your AI assistant can call directly.

## See it work

**Claude.ai catches 6 fabricated citations in a real draft — using Thoth's audit:**

<div align="center">
<img src="docs/assets/m5-mcp-demo.gif" alt="Claude.ai connected to Thoth via MCP, using get_citation_audit to identify 6 unsupported claims" width="760" />
</div>

> Connected to Thoth via the [official MCP Registry](https://registry.modelcontextprotocol.io/v0/servers?search=io.github.ahmedEid1/thoth), Claude calls `get_citation_audit` on **one deliberately-weak review** (faithfulness 0.13 for that single review) and identifies all 6 unsupported claims — every one citing the same paper, with invented percentages that aren't in the source. This is `cite_check` doing its job: it's a single-review audit sample, not the golden-set aggregate (see [`/evals`](https://thoth-slr.vercel.app/evals)).

**Every claim, scored against its source** — the `/showcase` review (no login needed). The figures on this card (critic 4.2/5, faithfulness 75%, 8/8 citations checked, 2 unsupported) are **this one review's** scores — a worked example, not the aggregate:

<div align="center">
<img src="docs/assets/media/02-showcase.png" alt="A completed Thoth review: critic 4.2/5, citation faithfulness 75%, 8/8 citations checked with 2 unsupported — scores for this single sample review" width="760" />
</div>

**Evaluated in public** — [`/evals`](https://thoth-slr.vercel.app/evals) tracks citation recall / precision / faithfulness / coverage over an 18-question versioned golden set (7 of 18 populated at this commit), regenerated in CI and published with the last-run date, so a regression is a public, falsifiable signal:

<img src="docs/assets/media/03-evals.png" alt="Thoth's public eval dashboard — citation recall, precision, faithfulness, and coverage per golden question" width="760" />
</div>

**You approve every step** — three human-in-the-loop gates (review plan → review discovered papers → approve included papers); nothing runs unattended:

## Key features

- **🔎 `cite_check` — verifiable citations.** Every `[paper_id]` in the draft is
  scored against the cited paper and labelled supported / unsupported / unclear,
  so the LLM can't quietly hallucinate a citation. On the public golden set, the
  citations it *does* surface are accurate — **citation precision 97%, recall 74%**
  — and the verdict report is published per claim, not summarised away. This is the
  core differentiator: the citations are measured, not asserted.
- **🌐 Outbound web search (v2 — under active evaluation).** An outbound
  `discoverer → fetcher → screener` path is wired across **OpenAlex**, **arXiv**, and
  **Exa**: it fetches open-access PDFs, OCRs them, and screens each against your plan,
  so you can run uploaded-only, hybrid, or fully autonomous discovery. The discovery
  and screening axes are **v2 and still being calibrated** — they're tracked openly on
  [`/evals`](https://thoth-slr.vercel.app/evals) (both currently at 0%) rather than
  shipped as a silent claim.
- **🔌 Authenticated, registered MCP server.** OAuth 2.1 + PKCE + Dynamic Client
  Registration via Clerk, SHA-256 audit logging, rate limits — listed in the
  [official MCP Registry](https://registry.modelcontextprotocol.io/v0/servers?search=io.github.ahmedEid1/thoth).
  Most public MCP servers ship with no auth; this one doesn't.
- **📊 Public eval dashboard.** Recall / precision / faithfulness / coverage over a
  versioned golden set, regenerated in CI and stamped with the last-run date, rendered at
  [`/evals`](https://thoth-slr.vercel.app/evals) — an eval regression is a *public*
  signal, not a hidden one.
- **💸 6 LLM providers, $0/mo by default.** Swap providers with one env var; the Mistral
  free tier runs the whole thing, and the entire stack deploys on free tiers for
  **$0/mo**.

## 🚀 Quickstart

cp .env.example .env        # Clerk + Trigger.dev keys + MISTRAL_API_KEY
docker compose up -d        # postgres, minio, langfuse
pnpm install && pnpm prisma migrate dev
pnpm dev                    # Next.js on :3000
pnpm dev:trigger            # Trigger.dev worker (separate terminal)
```
