mcp-mgccli

mcp-mgccli

MCP-Server für Leseabfragen in der Magalu Cloud via mgc CLI.

Stellt 7 MCP-Tools (eines pro Produkt) bereit, die list- und get-Operationen abdecken. Die gesamte Authentifizierung erfolgt über einen API-Key – keine Anmeldedaten im Code.

Anforderungen

  • Python 3.11+

  • mgc CLI v0.54.0+ im PATH

  • Magalu Cloud API-Key mit Leseberechtigungen

Related MCP server: cloud-chat-assistant

Installation

pip install -e /caminho/para/mcp-mgccli

Konfiguration

Kopieren Sie die Beispieldatei und tragen Sie Ihren API-Key ein:

cp .env.example .env

.env:

MGC_API_KEY=sua-api-key-aqui
MGC_REGION=br-ne1   # opcional — br-ne1 ou br-se1
MGC_TIMEOUT=30      # opcional — timeout em segundos (default: 30)

Integration mit Claude Code

Der Server wird automatisch über start-mcp.sh gestartet, das die .env-Datei lädt. Zur Registrierung:

claude mcp add --scope user mgc /caminho/para/mcp-mgccli/start-mcp.sh

Oder fügen Sie es manuell in ~/.claude.json hinzu:

{
  "mcpServers": {
    "mgc": {
      "command": "/caminho/para/mcp-mgccli/start-mcp.sh"
    }
  }
}

Integration mit Claude Desktop

Bearbeiten Sie ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) oder %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "mgc": {
      "command": "/caminho/para/mcp-mgccli/start-mcp.sh"
    }
  }
}

B3.4/5.0
Behavior3/5

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

With no annotations, the description carries the full burden. It correctly indicates read-only behavior and global scope, but lacks details on pagination, rate limits, or how the optional 'id' parameter affects behavior.

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

Conciseness4/5

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

The description is two sentences and contains no extraneous information. It is well-front-loaded but could add more details without becoming verbose.

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

Completeness3/5

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

Given the existence of an output schema and the tool's simplicity, the description provides the essential scope (read-only, global). However, it lacks guidance on when to use 'list' vs 'get' or the role of 'id', leaving the agent with incomplete context.

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?

Schema description coverage is 0%, so the description must compensate. It partially does by listing the allowed resources, matching the 'resource' enum. However, it does not explain the 'action' or 'id' parameters, which are necessary for correct invocation.

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 it's for consulting Audit events (read-only) and lists the specific resources (events, event-types). This effectively distinguishes it from sibling tools which focus on other cloud services.

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

Usage Guidelines3/5

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

The description mentions it's read-only and global (no region parameter), providing some context. However, it does not explicitly state when to use this tool versus alternatives or provide exclusions, leaving room for ambiguity.

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

D1.7/5.0

Scored across 7 tools

Disambiguation1/5

Six of the seven tools have no descriptions, making it impossible to distinguish their specific functions beyond the generic resource names. Only 'audit' has a description, but the others are ambiguous.

Naming Consistency4/5

All tool names are single-word, lowercase nouns (e.g., 'audit', 'network'), following a consistent pattern. However, they lack verbs, which is unconventional for MCP tool naming.

Tool Count4/5

With 7 tools, the count is reasonable for a cloud service provider's MCP interface, covering several major resource categories without being excessive.

Completeness2/5

The set covers core services like compute, storage, networking, and databases, but without descriptions, it's unclear what operations are available. The lack of detail suggests significant gaps in the tool surface.
