Overview

Description from the maker (original English)

Open watchdog for retracted & problematic citations: Retraction Watch, OpenAlex, Crossref.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs on your computer
  • Transport: stdio
  • Category: Other
  • You need to fill in: OPENALEX_API_KEY

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • You fill in yourself: OPENALEX_API_KEY, CITEGUARD_MAILTO

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

  • PyPIPython’s uv installed (for the uvx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "retractguard": {
      "command": "uvx",
      "args": [
        "retractguard"
      ],
      "env": {
        "OPENALEX_API_KEY": "your-value",
        "CITEGUARD_MAILTO": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add retractguard --env OPENALEX_API_KEY=your-value --env CITEGUARD_MAILTO=your-value -- uvx retractguard

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "retractguard": {
      "command": "uvx",
      "args": [
        "retractguard"
      ],
      "env": {
        "OPENALEX_API_KEY": "your-value",
        "CITEGUARD_MAILTO": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "retractguard": {
      "type": "stdio",
      "command": "uvx",
      "args": [
        "retractguard"
      ],
      "env": {
        "OPENALEX_API_KEY": "your-value",
        "CITEGUARD_MAILTO": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

Common questions

Is CiteGuard safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: OPENALEX_API_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.2) reached the registry 4 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

What can I use instead?

CiteGuard

The free, open, OpenAlex-native watchdog for retracted and problematic citations.

CiteGuard tells you — and keeps telling you — when your references, your authors, or your institution's papers cite research the community has flagged as retracted, corrected, or subject to an expression of concern.

It exists because the existing options each fall short: scite is proprietary and paywalled, RetractoBot had to license Scopus (no open citation database existed at the time), and OpenAlex collapses all editorial status into a single is_retracted boolean that can't tell a retraction from a correction — and has produced false positives in the past.

Now that the Retraction Watch dataset is open (via Crossref) and the OpenAlex citation graph is CC0, CiteGuard can do this fully in the open, for free.

Status: early development. Building the MVP. See GOAL.md for the mission and

CLAUDE.md for the build guide.

What it does

  • Check a reference list. Paste a DOI or upload a .bib file → get a per-reference status: retracted, corrected, expression of concern, hijacked-journal, or clean.
  • Nuanced status, not a boolean. Every flag carries its source (Retraction Watch / OpenAlex / Crossref), an evidence link, a date, and a confidence note. When sources disagree, CiteGuard surfaces the conflict instead of silently guessing.
  • Watch an institution. Point it at a ROR ID → get a digest when any of that institution's works cites (or becomes) a newly-flagged paper.
  • Use it from an AI agent. An MCP server exposes the same logic as tools (check_references, get_editorial_status, watch_institution) for Claude, Cursor, and any MCP-compatible client.

Why it's trustworthy

Integrity tooling can do real harm if it's wrong — a false "retracted" flag damages a real author. CiteGuard is conservative by design: it corroborates before flagging, prefers the documented editorial notice, and marks a work UNKNOWN rather than guess. Every core capability ships with a published eval reporting precision and recall on a gold set.

Who it's for

  • Research-integrity officers and journal editors screening submissions
  • Academic librarians at OpenAlex-adopting institutions
  • Systematic reviewers (one retracted included study can invalidate a review)
  • Developers and meta-scientists building on the MCP server
  • Authors checking their own bibliography before submission

Architecture

One core, two surfaces.

                 ┌─────────────────────────────┐

OpenAlex ─────▶ │ (CC0 graph) │ editorial-status model │──▶ MCP server │ + resolution logic │ (check_references, Retraction ──▶│ (conservative) │ get_editorial_status, Watch (open) │ │ watch_institution) │ │──▶ reference-list checker Crossref ─────▶ │ (DOI / .bib → statuses, (DOI norm.) └─────────────────────────────┘ thin web UI)

Repository layout:

src/citeguard/

openalex.py # keyed, rate-aware, ID-lookup-first OpenAlex client retractionwatch.py # ingest + normalize the Retraction Watch dump status.py # the EditorialStatus model + resolution logic (core) checker.py # reference-list checker (DOI / .bib -> statuses) mcp_server.py # MCP server exposing the three tools tests/ # pytest unit + functional tests evals/ # gold sets + precision/recall harness data/ # local RW dump + cached lookups (gitignored)

Design constraints (important)

  • Free-tier-aware. OpenAlex API keys are required (since Feb 13, 2026); the free tier is small and search costs ~10× a record lookup. CiteGuard resolves to IDs first and looks up by ID; bulk work uses the free monthly snapshot, and the live API is reserved for incremental checks.
  • Open and reproducible. CC0 ethos, with proper attribution to Retraction Watch and OpenAlex, thorough docs, and a Zenodo DOI.

Getting started (dev)

Requires Python 3.11+ and uv.

uv sync                                   # install dependencies

export OPENALEX_API_KEY=... # your OpenAlex key export CITEGUARD_MAILTO=you@example.org # polite-pool contact

uv run pytest # run tests uv run python -m evals.run # run the eval harness (precision/recall) uv run python -m citeguard.mcp_server # launch the MCP server locally

Connect it as an MCP server

CiteGuard exposes get_editorial_status, check_references, and watch_institution to any MCP client. After pip install retractguard (or uv tool install retractguard), the retractguard-mcp command launches the stdio server.

Claude Desktop — add to claude_desktop_config.json:

{

"mcpServers": { "retractguard": { "command": "retractguard-mcp", "env": { "OPENALEX_API_KEY": "your-key", "CITEGUARD_MAILTO": "you@example.org" } } } }

Cursor / other clients — point them at the same retractguard-mcp command (stdio transport). Running from a checkout instead of an install? Use "command": "uv", "args": ["run", "retractguard-mcp"] with "cwd" set to the repo.

On first call the server downloads the Retraction Watch dump (~65 MB, free) into CITEGUARD_DATA_DIR (default ./data). Editorial-notice lookups (Retraction Watch, Crossref) need no key; OpenAlex corroboration and watch_institution do.

The web checker

A thin web UI for people who don't live in an editor — paste DOIs or drop a .bib file, get a per-reference status table.

retractguard-web            # then open http://127.0.0.1:8000

or from a checkout: uv run python -m citeguard.web

Add Accept: application/json to POST /check to get the results as JSON instead of a table. It reuses the same conservative resolution logic as the MCP server — no separate code path, no separate trust model.

Roadmap (MVP)

  1. status.py — the normalized editorial-status model (foundation)
  2. retractionwatch.py — ingest + normalize the Retraction Watch dump
  3. openalex.py — keyed, ID-first client
  4. checker.py — DOI / .bib → statuses
  5. mcp_server.py — expose the three tools
  6. evals/ — gold set + precision/recall harness (running from step 2 onward)

Credits & data

  • OpenAlex — CC0 scholarly metadata and citation graph.
  • Retraction Watch — retraction database, made openly available via Crossref.
  • Crossref — DOI infrastructure.

CiteGuard is independent and not affiliated with these projects; it builds on their open data with gratitude.

License

MIT (see LICENSE) — permissive and maximally reusable, in keeping with the open-science ethos in GOAL.md.

The code is CiteGuard's. The data it builds on is not and carries its own terms: Retraction Watch (via Crossref) and OpenAlex/Crossref metadata. CiteGuard redistributes only a tiny evaluation extract (see evals/fixtures/ATTRIBUTION.md); anything at scale should be fetched from the upstream sources under their licenses.
