mcp-powershell-exec
Provides an MCP server that accepts PowerShell scripts as strings, executes them, and returns the execution output to the caller/agent in real time.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
README indicates arbitrary PowerShell script execution, which is effectively remote code execution within the host environment. No authentication, authorization, scoping/allowlisting, sandboxing, TLS requirements, auditing, or secret-handling/logging protections are documented in the provided content. Treat as high-risk unless the implementation enforces strict controls (not evidenced here).
⚡ Reliability
Best When
Used in a controlled, self-hosted environment where the agent can only run approved commands/scripts and operators can inspect/limit impact.
Avoid When
Avoid when the MCP server is reachable by untrusted users or when script inputs are not sanitized/validated and execution is not constrained.
Use Cases
- • Enable AI assistants/agents to run PowerShell commands for automation
- • Globus of infrastructure automation tasks where PowerShell is the execution language
- • Local or self-hosted ops workflows controlled via MCP tool calls
Not For
- • Executing untrusted or user-supplied scripts without strong sandboxing/allowlisting
- • Production environments requiring strict auditing, least-privilege, and hardened execution controls (as documentation does not show these)
- • Use as a general-purpose remote code execution service exposed broadly
Interface
Authentication
No authentication/authorization mechanism is described in the provided README content; MCP servers are typically configured locally, but security properties are not documented here.
Pricing
Open-source (MIT) with no pricing details provided.
Agent Metadata
Known Gotchas
- ⚠ Free-form script execution is inherently risky; agents may unintentionally run destructive commands.
- ⚠ Output size/streaming and timeouts are not documented in the provided content; long-running scripts may cause failures or hangs.
- ⚠ No documented allowlist/denylist or sandboxing guidance—agents need operational guardrails outside the tool.
