README
up-law-argleg-mcp
Servidor MCP que expone el corpus legal de la base up_law_argleg_db (legislacion
nacional argentina + jurisprudencia CSJN + tratados internacionales de
Cancilleria) a Claude, con proveniencia
verificable en cada respuesta: el abogado puede rastrear cada texto al
documento oficial capturado (sha256 + fecha + URL de InfoLEG) y auditar
cualquier cita textual con el tool verificar_cita.
Requisitos
- Docker Desktop (Postgres 16 + pgvector via docker compose del proyecto infoleg)
- Python >= 3.12 y uv
- La base
up_law_argleg_dbcargada (ver proyecto hermano../infoleg)
Instalacion (macOS / Windows)
# 1. base con pgvector (en el proyecto infoleg)
cd ../infoleg && docker compose up -d
# 2. dependencias
cd ../mcp-v2 && uv sync
# 3. schema mcp + roles (idempotente)
uv run up-law-argleg-mcp setup-db
# 4. embeddings (primera vez: 2-4 h; incrementales: minutos)
uv run up-law-argleg-mcp index
# 5. smoke
uv run up-law-argleg-mcp status
Claude Desktop
Agregar a claude_desktop_config.json
(macOS: ~/Library/Application Support/Claude/,
Windows: %APPDATA%\Claude\):
{
"mcpServers": {
"up_law_argleg": {
"command": "uv",
"args": ["run", "--directory", "/RUTA/ABSOLUTA/a/mcp-v2", "up-law-argleg-mcp", "serve"]
}
}
}
En Windows la ruta usa barras invertidas escapadas: C:\\Users\\...\\mcp-v2.
Operacion
- Tras cada sync mensual del ETL infoleg:
uv run up-law-argleg-mcp index. uv run up-law-argleg-mcp statusmuestra frescura y cobertura.- Tests:
uv run pytest(unit) |uv run pytest -m live(requiere base) |uv run pytest -m model(carga el modelo de embeddings).
Garantia de fidelidad
- El servidor se conecta con un rol de solo lectura (
mcp_reader). - Los tools devuelven texto verbatim; el servidor jamas resume.
- Cada texto viaja con bloque
fuente(sha256 del documento oficial, fecha de captura, URL, offsets). verificar_citaconfirma si una cita existe literalmente en el corpus, y detecta citas casi-correctas mostrando el diff contra el texto real.- La base no determina vigencia: expone el grafo de modificaciones y las observaciones de InfoLEG; el analisis juridico es del profesional.
