MCP Server

Añade verificación de citas académicas a Claude Desktop, Cursor o cualquier cliente MCP compatible.

@citetrue/mcp-servernpx -y @citetrue/mcp-server

Qué obtienes

Dos herramientas que envuelven la API REST de CiteTrue. Mismos créditos, misma precisión — solo vía MCP en lugar de HTTP.

Herramienta	Propósito	Créditos / llamada
verify	Split a text blob into references and verify each against real sources.	1 per ref; tricky ones up to 5
get_credits	Devuelve el saldo de créditos de la cuenta.	0

Inicio rápido

Ir a Panel → Claves API y hacer clic en Nueva clave API. Copiar la clave que empieza con sk_.
Abrir la configuración del cliente MCP (ver Configuración del cliente) y añadir el bloque citetrue.
Reiniciar el cliente MCP — no solo el chat, la app entera.
Pedir al asistente "Verifica estas citas: [pegar]". Llamará verify y resumirá.

Configuración del cliente

Cualquier cliente MCP por stdio sirve. A continuación los tres más comunes; otros usan la misma estructura.

Claude Desktop

Recomendado

Instala CiteTrue como extensión de Claude Desktop — sin editar JSON ni configurar Node. El servidor empaquetado se ejecuta con el Node que incluye Claude Desktop.

Descargar para Claude Desktop

Haz doble clic en el archivo descargado (o arrástralo a Ajustes → Extensions) y pega tu clave API cuando se te solicite — se guarda de forma segura en el llavero de tu sistema.

Importante: tras instalar, asegúrate de que la extensión esté habilitada (activada) en Ajustes → Extensions y reinicia Claude Desktop — eso es lo que activa sus herramientas.

O configurar manualmente

Editar ~/Library/Application Support/Claude/claude_desktop_config.json en macOS, %APPDATA%\Claude\claude_desktop_config.json en Windows:

{
  "mcpServers": {
    "citetrue": {
      "command": "npx",
      "args": ["-y", "@citetrue/mcp-server"],
      "env": {
        "CITETRUE_API_KEY": "sk_..."
      }
    }
  }
}

Cursor

En Settings → MCP → Add new MCP server, usar la misma estructura command/args/env que el JSON de Claude Desktop abajo.

Windsurf, Zed, otros

Cualquier cliente MCP stdio funciona — sea cual sea la ruta de config, los tres mismos campos (command, args, env).

Configuración

Variable de entorno	Predeterminado	Notas
CITETRUE_API_KEY	— (Requerido)	Token Bearer del dashboard.
CITETRUE_API_URL	`https://api.citetrue.com`	Sobrescribir para despliegues self-hosted.

Herramientas

verify

Split a free-form text blob into individual references and verify each against real sources. Every reference goes through the same flow, and each one in the result reports what it cost.

Parámetros

Supply exactly one of text or taskHash:

text string — raw text containing one or more references: numbered / bulleted / blank-line-separated lists, BibTeX, or prose with in-text author-year citations. Max 10MB.
taskHash string — resume a task started by an earlier call (the taskHash it returned). Finished results are replayed without charging again; citations that still need checking are completed and billed as usual.
force bool, optional — ignore cached results and check the text again from scratch (billed like a new check). Only applies with text.

Salida

{
  "taskHash": "...",
  "refs": [
    {
      "hash": "a1b2c3...",
      "text": "[1] Vaswani, A., Shazeer, N., Parmar (2017)...",
      "assessment": "authentic",
      "value": {
        "type": "citation",
        "title": "Attention is all you need",
        "authors": ["A Vaswani", "N Shazeer", "N Parmar"],
        "year": 2017,
        "url": "https://..."
      },
      "note": "",
      "notices": [],
      "confidence": 0.97,
      "cost": 1
    }
  ],
  "cost": 2,
  "balance": 248
}

Each ref's cost is what the task has charged for that citation: 1 for most citations, up to 5 for tricky ones that needed more data sources and more analysis, 0 if it was already paid for in another task. Resuming a task with taskHash reports the same per-ref numbers again — they are not new charges. The top-level cost is what this call newly charged (0 when a finished task is simply replayed), and balance is what's left afterwards — it can be negative (see Billing). note is a free-form one-line natural-language explanation in English (intended for end-user display); for programmatic checks, match on notices[] instead.

Assessment values

authentic — paper exists and is the one cited; value contains the matched paper.
unsure — found something but can't confirm; notices and confidence describe why.
inauthentic — definitively not found / fabricated / unrelated.
invalid — input wasn't a citation; pipeline refused to search.
error — verification failed on this ref; errors[] lists tokens.
exceeded — credits ran out before this ref ran.

Facturación

Same credits as the REST API. Most citations cost 1 credit. Tricky ones that need more data sources and more analysis can cost up to 5. If you run out of credits mid-check, citations already in progress still finish; the overage is deducted at your next credit reset, so balance can be negative. Citations that couldn't start for lack of credits come back as exceeded. get_credits is free.

Solución de problemas

If the server fails to start, ensure npx is on PATH and CITETRUE_API_KEY is set.
