Paper-request MCP: track, resolve, fetch (OA-only), and flag misconceptions for scientific papers
Wellknown found it in public sources; nobody has proven control of it yet. Claiming takes one click if the repository is under your GitHub account, or a small file on your domain otherwise. Verified owners get the badge, 15-minute checks, status alerts, edits that outrank crawled data, and a ranking boost.
Agents can do it too: POST https://wellknown.network/api/v1/claims with {"agent":"acatome-quest-mcp","method":"well_known_file"} — machine-readable steps at claim.json, guide at /docs/claim.
Everything here was measured by our prober or read from a registry. Nothing is self-reported.

# acatome-quest-mcp **Paper-request MCP for scientific papers.** The missing piece between [`precis-mcp`](https://github.com/retospect/precis-mcp) (navigates what's already in your library) and [`acatome-extract`](https://github.com/retospect/acatome-extract) (ingests PDFs that land in an inbox). An LLM says *"I want this paper"* (DOI, arXiv id, title, or free-form citation). Quest: 1. **Checks the store first** — no duplicate work if we already have it. 2. **Resolves the metadata** via Crossref + Semantic Scholar + arXiv. 3. **Flags misconceptions** — broken DOI, DOI↔title mismatch, duplicate of an existing slug, fabrication suspect. 4. **Fetches the PDF** from legitimate open-access sources only and drops it into the existing watch inbox, where `acatome-extract` takes over. 5. Returns a **request id** in milliseconds. Slow extraction happens out of band; the MCP call never blocks. ## Open access only — by policy Quest fetches from **arXiv, Unpaywall, OpenAlex, Europe PMC, and Semantic Scholar's open-access index only**. It does not, will not, and cannot be configured to use Sci-Hub, LibGen, institutional proxies without explicit opt- in, or any other paywall-circumvention mechanism. Failed retrievals yield a `needs_user` status with the publisher URL, for you to retrieve manually. ## Install ```bash pip install acatome-quest-mcp # or with uv uv add acatome-quest-mcp ``` For dedup against a local `acatome-store`: ```bash pip install 'acatome-quest-mcp[store]' ``` ## Four tools | Tool | What it does | |------|--------------| | `submit(ref, *, dry_run=False, source=None, priority=0, created_by=None)` | Resolve + optionally queue. Idempotent. | | `status(id=None, *, filter=None)` | Read one or many requests. | | `update(id, mode, **kwargs)` | Mutate. Modes: `confirm`, `repoint`, `flag`, `priority`, `cancel`. | | `submit_file(url?, content_base64?, filename?, request_id?, ref?, created_by?)` | Attach a user-supplied PDF (e.g. Discord attachme…
