      const { stdout, stderr } = await execAsync(`powershell -Command "${command.replace(/"/g, '\\"')}"`);

      if (stderr) {
        return {
          isError: true,
          content: [
            {
              type: "text" as const,
              text: `Error in my_ps_tool: ${stderr}`,
            },
          ],
        };
      }

            text: stdout,
          },
        ],
      };
    } catch (error) {
      return {
        isError: true,
        content: [
          {
            type: "text" as const,
            text: `Error in my_ps_tool: ${(error as Error).message}`,

Consideraciones de seguridad

  • Este servidor ejecuta comandos de PowerShell directamente en su sistema

  • Los comandos se ejecutan con los mismos privilegios que el proceso que ejecuta el servidor MCP

  • Tenga cuidado al exponerse a operaciones destructivas

  • Considere implementar una validación adicional para comandos sensibles

Solución de problemas

Problemas comunes

  1. Restricciones de la política de ejecución de PowerShell

    • Es posible que necesite ajustar su política de ejecución de PowerShell para permitir la ejecución de scripts

    • Utilice Set-ExecutionPolicy RemoteSigned -Scope CurrentUser para permitir scripts locales

  2. Errores de ruta no encontrada

    • Asegúrese de que las rutas de archivo sean absolutas o relativas al directorio de trabajo

    • Utilice separadores de ruta adecuados para su sistema operativo

  3. Errores de comando no encontrado

    • Algunos comandos pueden requerir la instalación de módulos específicos

    • Utilice Install-Module ModuleName para instalar los módulos necesarios

TDQS

D1/5.0
Behavior1/5

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

Tool has no description.

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

Conciseness1/5

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

Tool has no description.

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

Completeness1/5

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

Tool has no description.

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

Parameters1/5

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

Tool has no description.

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

Purpose1/5

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

Tool has no description.

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

Usage Guidelines1/5

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

Tool has no description.

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

TDQS

C2/5.0

Scored across 6 tools

Disambiguation5/5

Each tool has a clearly distinct purpose with no overlap: execute_ps runs commands, find_commands searches for commands, get_command_help provides documentation, get_system_info retrieves system data, list_modules shows available modules, and run_script executes script files. The verbs and nouns clearly differentiate their functions.

Naming Consistency5/5

All tool names follow a consistent snake_case verb_noun pattern (e.g., execute_ps, find_commands, get_command_help). The naming is uniform throughout with no deviations in style or convention.

Tool Count4/5

With 6 tools, the count is reasonable for a PowerShell server, covering core operations like command execution, help, and system info. It might benefit from additional tools for more advanced PowerShell features, but it's well-scoped for basic functionality.

Completeness3/5

The tools cover essential PowerShell operations like executing commands, getting help, and listing modules, but there are notable gaps such as no tools for managing processes, services, or files, which are common in PowerShell workflows. The surface is functional but incomplete for full domain coverage.
