Servidor Bruno MCP

insignia de herrería

Un servidor MCP (Protocolo de Contexto de Modelo) que permite ejecutar colecciones de Bruno. Este servidor permite a los LLM ejecutar pruebas de API con Bruno y obtener resultados detallados mediante una interfaz estandarizada.

Características

  • Ejecutar colecciones de Bruno mediante la CLI de Bruno

  • Soporte para archivos de entorno

  • Soporte para variables de entorno

  • Resultados detallados de las pruebas que incluyen:

    • Estado general de éxito/fracaso

    • Resumen de la prueba (total, aprobado, reprobado)

    • Información detallada sobre fallos

    • Tiempos de ejecución

Related MCP server: bruno-mcp

Instalación

Instalación mediante herrería

Para instalar Bruno MCP Server para Claude Desktop automáticamente a través de Smithery :

npx -y @smithery/cli install @hungthai1401/bruno-mcp --client claude

Instalación manual

# Install dependencies
npm install

# Build the project
npm run build

Configuración

Agregue el servidor a su archivo de configuración de escritorio Claude en ~/Library/Application Support/Claude/claude_desktop_config.json :

{
  "mcpServers": {
    "bruno-runner": {
      "command": "npx",
      "args": ["-y", "bruno-mcp"],
    }
  }
}

Herramientas disponibles

colección de carreras

Ejecuta una colección de Bruno y devuelve los resultados de la prueba.

Parámetros:

  • collection (obligatorio): Ruta a la colección Bruno

  • environment (opcional): Ruta al archivo de entorno

  • variables (opcional): Variables de entorno como pares clave-valor

Ejemplo de respuesta:

{
  "success": true,
  "summary": {
    "total": 5,
    "failed": 0,
    "passed": 5
  },
  "failures": [],
  "timings": {
    "started": "2024-03-14T10:00:00.000Z",
    "completed": "2024-03-14T10:00:01.000Z",
    "duration": 1000
  }
}

Ejemplo de uso en Claude

Puedes usar el servidor en Claude pidiéndole que ejecute una colección de Bruno:

Ejecute la colección Bruno en /path/to/collection.bru y dígame si se aprobaron todas las pruebas.

Claude querrá:

  1. Utilice la herramienta de recopilación de ejecuciones

  2. Analizar los resultados de las pruebas

  3. Proporcionar un resumen comprensible de la ejecución.

C2.9/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden of behavioral disclosure. It mentions 'Run' which implies execution, but fails to describe critical behaviors like whether it's read-only/destructive, requires specific permissions, has side effects (e.g., file changes), or handles errors. This leaves significant gaps for an execution tool.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, efficient sentence with zero wasted words. It's appropriately sized and front-loaded, clearly stating the core action without unnecessary elaboration.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the complexity of running a collection (an execution tool with potential side effects), no annotations, and no output schema, the description is incomplete. It lacks details on behavior, output format, error handling, or dependencies, making it inadequate for safe and effective use by an AI agent.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema description coverage is 100%, so the schema already documents all parameters (collection path, optional environment file, optional variables). The description adds no additional meaning beyond what the schema provides, such as format examples or usage context, meeting the baseline for high coverage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb ('Run') and resource ('a Bruno Collection using Bruno CLI'), making the purpose understandable. However, it doesn't differentiate from siblings since there are none, so it can't achieve the full 5 points for sibling differentiation.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool, such as prerequisites (e.g., Bruno CLI installation), alternatives, or specific contexts. It only states what the tool does without usage instructions.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Disambiguation5/5

With only one tool, there is no possibility of confusion or overlap between tools. The tool 'run-collection' has a single, clearly defined purpose that cannot be misselected against other tools.

Naming Consistency5/5

Since there is only one tool, naming consistency is inherently perfect. The tool name 'run-collection' follows a verb-noun pattern, and there are no other tools to compare it against for inconsistency.

Tool Count2/5

A single tool is generally too few for most server purposes, as it limits functionality and may indicate an incomplete or overly narrow scope. While it could be appropriate for a very specific task, it often feels thin and lacks the breadth needed for typical agent workflows.

Completeness1/5

With only one tool, the surface is severely incomplete. There are obvious gaps, such as the inability to create, list, update, or delete collections, which are typical operations in a collection management domain. This will likely cause agent failures when trying to perform basic tasks beyond running a collection.
