yotsuda/PowerShell.MCP — The universal MCP server for Claude Code and other MCP-compatible clients.

Description and use

**Brief summary (2‑3 sentences)**
PowerShell.MCP is a universal Model‑Context‑Protocol (MCP) server that lets Claude Code and any MCP‑compatible AI client invoke over 10 000 PowerShell modules and arbitrary CLI tools from a shared console. It works on Windows, Linux and macOS, enabling a transparent, bidirectional collaboration between a human and an AI assistant. The project is written in C# and is actively maintained as of June 2026.

**Value**

• **Real‑world tool access:** By exposing the full PowerShell ecosystem (and any installed CLI), the server gives LLMs concrete, up‑to‑date capabilities instead of relying on static knowledge bases.
• **Standardised integration:** MCP is a vendor‑agnostic protocol, so the same server can serve Claude, other LLMs, or custom agents without code changes.
• **Cross‑platform consistency:** A single installation works on Windows, Linux and macOS, simplifying ops for mixed‑environment teams.

**Practical adoption path**

1. **Prototype:** Clone the repo, run the provided Docker image or binary, and point your MCP‑compatible client (e.g., Claude Code) at the server’s endpoint. Verify that the AI can list, import, and execute a few PowerShell modules.
2. **Secure the surface:** Add authentication (e.g., API‑key or mutual TLS), restrict the allowed modules/CLI tools, and enable audit logging.
3. **Integrate into CI/CD:** Package the server as a container or a system service, configure environment‑specific module sets, and expose the endpoint to your internal AI orchestration layer.
4. **Scale & monitor:** Deploy multiple replicas behind a load balancer, use Prometheus metrics (if instrumented) for health, and establish alerts for abnormal command patterns.

**Production readiness**

• **Maturity:** Medium. The project has recent commits, a modest star count (≈74) and basic documentation, making it suitable for internal prototypes and controlled production use.
• **Dependencies:** Relies on the host’s PowerShell installation and any external CLI tools you expose; these must be vetted and kept up‑to‑date.
• **Risks:** No formal security review or enterprise‑grade hardening is included; licensing and maintainer activity need confirmation before a public‑facing rollout. With proper sandboxing, authentication, and monitoring, PowerShell.MCP can be safely promoted to production for internal workflows.

Problem

yotsuda/PowerShell.MCP helps connect AI assistants to real tools and data through a standard protocol.

Outcome

Medium: useful for prototypes or internal workflows, with dependency and maintenance checks before production.

Workflow

• connect AI agents to tools
• ship Model Context Protocol servers
• standardize integrations

Evidence

The universal MCP server for Claude Code and other MCP-compatible clients. One installation gives AI access to 10,000+ PowerShell modules and any CLI tool. You and AI collaborate in the same console with full transparency. Supports Windows, Linux, and macOS.
