Common questions

Is Corpus Iuris safe?

It passed 4 of 4 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?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed 3 months ago, and the latest version (1.0.0) reached the registry 3 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT Business and above.

What can I use instead?

Corpus Iuris — derecho mexicano para agentes de IA

Mexican law for AI agents. Search 6,710 federal and state statutes,

311,701 Supreme Court *tesis* and 11,708 precedents — with verifiable

citations, dated validity and a public URL for every document.


El problema

Las IA inventan derecho mexicano. Citan tesis con número de registro que no existe, artículos que fueron derogados, y jurisprudencia que en realidad es una tesis aislada. En un litigio eso cuesta un asunto.

La solución

Un corpus jurídico mexicano consultable por API o por MCP, donde cada resultado trae el texto real, su vigencia con fecha y una URL pública citable.


Conectar en un clic (MCP)

Servidor MCP remoto con OAuth 2.0 (registro dinámico RFC 7591 + PKCE S256):

https://api.corpusiuris.mx/mcp

Claude Desktop / Claude.ai → Ajustes → Conectores → Agregar conector personalizado → pega la URL. El OAuth se descubre solo.

Cualquier cliente MCP — claude_desktop_config.json, Cursor, Windsurf, VS Code:

{

"mcpServers": { "corpus-iuris": { "url": "https://api.corpusiuris.mx/mcp" } } }

Tool disponible: buscar_derecho_mexicano(query, fuentes).


Sin registro: la API REST

Sin API key. Sin cuenta. Copia y pega:

curl "https://corpusiuris.mx/api/agent/v1/search?q=requisitos+de+la+orden+de+cateo&fuentes=leyes,tesis"
Las tres rutas
RutaPara qué
GET /api/agent/v1/search?q=…&fuentes=…Buscar. Hasta 5 resultados por fuente.
GET /api/agent/v1/documento?tipo=ley&id=slug/numTexto íntegro. No gasta cuota.

Lo que hace citable una respuesta

{

"tipo": "ley", "referencia": "Art. 17", "titulo": "LEY DE AMPARO, REGLAMENTARIA DE LOS ARTÍCULOS 103 Y 107…", "url": "https://corpusiuris.mx/ley/ley-de-amparo…/articulo/17", "vigencia": { "estado": "VIGENTE", "fecha_ultima_reforma": "2025-10-16", "verificado_al": "2026-08-17", "fuente_oficial": "https://www.diputados.gob.mx/LeyesBiblio/pdf/LAmp.pdf", "como_citar": "Di 'vigente al 2026-08-17' y enlaza la fuente oficial." } }

Y en jurisprudencia, el dato que evita el error clásico:

"fuerza": {

"es_jurisprudencia_obligatoria": false, "como_citar": "Tesis AISLADA: orientadora, NO obligatoria. No la cites como jurisprudencia." }

  • Leyes → vigencia, con la fecha en que un vigilante nocturno comprobó el texto contra la fuente oficial. Una ley abrogada sale con ADVERTENCIA.
  • Tesis → fuerza: obligatoria o aislada.
  • Precedentes → fuerza: son sentencias, no jurisprudencia por sí mismas.

Dos reglas

  1. Cita la fuente. «Corpus Iuris (corpusiuris.mx)» + el enlace url de cada resultado que uses. Los textos legales son información pública; la búsqueda y la curación son de Corpus Iuris.
  2. No caches. El corpus cambia todos los días: el vigilante recorre ~1,000 leyes cada noche, el DOF publica reformas y la SCJN sube tesis. Las respuestas se sirven con Cache-Control: no-store por esa razón.

Ejemplos


In English

Corpus Iuris is a Mexican legal corpus built for AI agents. Free REST endpoint (no key), native MCP server with one-click OAuth, and a public citable page for every document. Every result carries dated validity and, for case law, whether it is binding jurisprudence or a merely persuasive *tesis aislada* — the distinction that most often trips up AI in Mexican law.

No sustituye la fuente oficial

Es una herramienta de investigación de carácter referencial. Para un escrito formal, verifica en el DOF, el Semanario Judicial o la gaceta oficial del estado — cada resultado trae el enlace directo.
