Katzilla

Más de 300 fuentes de datos públicos y gubernamentales gratuitas bajo una sola clave API: la API de datos para agentes de IA.

Katzilla agrega datos públicos de fuentes primarias (gobierno federal de EE. UU., jurisprudencia, salud, riesgos, economía, más de 17 portales de datos abiertos internacionales, Eurostat, BCE, OMS, OCDE, FMI, Banco Mundial y más) detrás de una única API REST y un servidor MCP. Cada respuesta incluye metadatos de citation estructurados (fuente, licencia, URL, frecuencia de actualización) y puntuación de quality (actualidad, tiempo de actividad, integridad, confianza).

Servidor MCP

La forma más rápida de usar Katzilla es como servidor MCP en Claude Desktop, Cursor, Windsurf, Continue o cualquier cliente MCP stdio.

Claude Desktop

Edite claude_desktop_config.json:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json
Linux: ~/.config/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "katzilla": {
      "command": "npx",
      "args": ["-y", "@katzilla/mcp"],
      "env": {
        "KATZILLA_API_KEY": "kz_your_key_here"
      }
    }
  }
}

Cursor

Añada a ~/.cursor/mcp.json (o al archivo .cursor/mcp.json local del proyecto):

{
  "mcpServers": {
    "katzilla": {
      "command": "npx",
      "args": ["-y", "@katzilla/mcp"],
      "env": {

TDQS

A4.2/5.0

Scored 2026-04-15 03:35 across 274 tools

Disambiguation5/5

Each tool is clearly distinct, targeting a specific data source or API within a well-defined domain (e.g., agriculture__usda-nass for crop statistics vs. agriculture__usda-fooddata for nutrient info). The naming convention with double underscores separates domains and sources, preventing overlap and making tool purposes unambiguous. An agent can easily differentiate between tools like 'crime__fbi-most-wanted' and 'crime__recap-docket' based on their descriptions.

Naming Consistency5/5

All 274 tools follow a strict and consistent naming pattern: 'domain__source-description' using snake_case throughout (e.g., 'economic__fred-series', 'environment__noaa-cdo'). This pattern is uniformly applied across all tools, with no deviations in style or structure, making the set highly predictable and readable.

Tool Count2/5

With 274 tools, the count is excessive for a single server's scope, even though the server aims to aggregate many data sources. This volume overwhelms typical agent workflows and exceeds reasonable scoping (25+ tools is considered heavy). While each tool is valuable individually, the collective size makes the server feel like a bundle of many mini-servers rather than a coherent set.

Completeness5/5

The tool set is exceptionally complete for its intended purpose of providing access to diverse public data APIs. It covers a wide range of domains (agriculture, crime, economics, health, etc.) with comprehensive coverage within each, including search, retrieval, and query operations. There are no apparent gaps; each tool serves a specific data source, and the set collectively supports extensive data access workflows without dead ends.
