Preguntas frecuentes

¿Es seguro Phở Research Tools?

Superó 2 de 3 revisiones básicas aplicables. No hemos leído el código. Antes de agregar una clave o un token, revisa qué acceso pide el servidor y usa una clave que tenga solo los permisos que necesitas.

¿Qué claves o códigos necesita?

El registro no indica ninguna clave obligatoria, aunque algunos servidores te piden iniciar sesión la primera vez que los usas.

¿Se ejecuta en mi computadora o en la nube?

Se ejecuta en la nube del creador. Te conectas por internet sin instalar nada, pero lo que envías pasa por los servidores del creador.

¿Sigue en mantenimiento?

El repo de GitHub cambió por última vez –, y la última versión (1.1.0) llegó al registro hace 17 días.

¿Qué apps pueden usarlo?

Las apps compatibles con MCP, como Claude Desktop, Claude Code, Cursor y VS Code. Se conecta por URL, así que también funcionan las apps que aceptan servidores MCP remotos, como ChatGPT en modo desarrollador.

Phở Research Tools

An open-source MCP server that lets any AI assistant check its own references. It verifies citations, flags retractions, finds the strongest evidence for a claim, formats bibliographies, runs PRISMA 2020 screening and finds open datasets and research software, using only open databases: Crossref, PubMed, OpenAlex, Europe PMC, DataCite, bio.tools and others.

AI models invent references. This server gives Claude, ChatGPT, Cursor or any MCP client a way to look each one up in a public database before you trust it.

ToolWhat it does
verify_referencesChecks each reference: verified, real but with wrong details (with the corrected record), likely fabricated, not found, retracted, or ambiguous.
check_retractionsRetraction, expression-of-concern and correction notices for a list of DOIs.
search_papersSearches OpenAlex and PubMed. Every result has a DOI or PMID; retracted papers are left out and preprints are labelled.
format_citationsAPA 7, MLA 9, Chicago, Harvard, Vancouver, IEEE or AMA, or BibTeX, RIS and CSL-JSON, formatted from the real record.
prisma_flow_diagramA PRISMA 2020 flow diagram (PNG + SVG) with a check that the counts add up.
find_evidenceThe strongest evidence on a claim, ordered by level of evidence (guideline, meta-analysis, RCT and down), each with its conclusion quoted verbatim.
screening_logTurns screening decisions into PRISMA counts, a diagram and a CSV log, and lists the problems a reviewer would catch.
find_datasetsOpen datasets for a research question, with licence verdicts, verified source papers and a shareable brief.
find_toolsResearch software for a task from the bio.tools registry, with licence verdicts, verified papers, maintenance labels and install lines.

All nine tools are read-only. Results are database lookups, not model opinions: likely_fabricated means the DOI is not registered or no matching record exists, and find_evidence never says whether a paper supports a claim; its quoted conclusion does.

Use the hosted server (no install)

Add this URL as a custom connector / MCP server in your client:

https://mcp.pho.chat/mcp
  • Claude Code: claude mcp add --transport http pho-research https://mcp.pho.chat/mcp
  • Claude (web, desktop): Settings → Connectors → Add custom connector.
  • ChatGPT: Settings → Apps & Connectors → Developer mode → Create.
  • Cursor, VS Code, others: see apps/mcp/README.md.

No account is needed. Anonymous use has a daily allowance; a free account at pho.chat raises it. Prefer a web page? The same tools run at pho.chat/tools.

Hand a whole research question to Phở's agent

With a Phở API key (pho_sk_…, from pho.chat/settings → API keys) sent as the header X-Pho-Api-Key, the same server adds run_research, get_research_run and cancel_research_run: your agent starts a full Phở research run (several rounds of PubMed search, retraction checks, evidence grading, a cited report), follows it, and gets the report back as Markdown. It runs on your Phở account (Pro or Founder plan; 0 credits when you saved your own model provider key in Phở).

claude mcp add --transport http pho-research https://mcp.pho.chat/mcp --header "X-Pho-Api-Key: $PHO_API_KEY"

Setup for Claude Code, Codex, Cursor, the OpenAI Agents SDK, LangGraph and plain REST: apps/mcp/examples/agents/.

Verified Citations skill

This repository also ships Verified Citations, an Agent Skill that makes an assistant use the tools above on every reference it writes: find sources with search_papers instead of recalling them, run verify_references before showing anything, format with format_citations, and say which references were corrected, retracted or removed.

Claude Code (plugin: skill + MCP server in one step)
claude plugin marketplace add thaohienhomes/pho-research-tools

claude plugin install verified-citations@pho-research-tools

The plugin adds the skill and connects the pho-research MCP server. Run /mcp to check the server shows as connected. From a local checkout, pass the folder path to marketplace add instead.

Cursor (Agent Plugin: skill + MCP server in one step)

The repository root is an Agent Plugin: plugin.json names the plugin, skills/ holds the skill, and mcp.json connects the pho-research server at https://mcp.pho.chat/mcp. Cursor loads it as-is:

  • Teams and Enterprise: Dashboard → Plugins & MCPs → Add Marketplace → Import from Repo, and paste https://github.com/thaohienhomes/pho-research-tools.
  • Local: clone or copy this repository to ~/.cursor/plugins/local/verified-citations, run Developer: Reload Window, and check under Customize that the plugin and the pho-research MCP server are listed.

The plugin logo is assets/logo.svg. Support: support@pho.chat.

skills.sh (Claude Code, Cursor, Codex, Gemini CLI and other agents)
npx skills add thaohienhomes/pho-research-tools --skill verified-citations

This installs the skill only. Connect the MCP server in your agent too, for example in Claude Code:

claude mcp add --transport http pho-research https://mcp.pho.chat/mcp
ClawHub (OpenClaw)
clawhub install verified-citations

Then add https://mcp.pho.chat/mcp as a remote MCP server in OpenClaw.

Claude.ai, ChatGPT and others

Add https://mcp.pho.chat/mcp as a custom connector; step-by-step instructions for each app are at https://pho.chat/tools/mcp/. Without the connector, paste a reference list into the free checker at https://pho.chat/tools/citation-checker/.

Run it yourself

Requires Node 22+ and pnpm 9.

pnpm install

pnpm dev # http://localhost:8787/mcp

Every setting is optional for a local run; see apps/mcp/.env.example. A Dockerfile is in apps/mcp/ (docker build -f apps/mcp/Dockerfile -t pho-mcp .).
