Node Version Check MCP Server

The Node Version Check server is a lightweight MCP service that reports the exact Node.js runtime environment in which an MCP server instance is executing. In modern AI assistant workflows, many tools and libraries depend on specific Node.js features or patch levels; knowing the runtime version at any point in time can prevent subtle bugs, compatibility issues, and security vulnerabilities. By exposing this information through the MCP interface, developers can programmatically verify that their AI-driven applications are running on a supported Node.js version without manual inspection of the host machine.

When invoked, the server returns a structured response containing the full Node.js version string (e.g., ), the major, minor, and patch numbers, as well as the runtime’s environment variables that influence module resolution. This data is useful for logging, monitoring, and conditional logic within AI agents: a Claude assistant could query the server before deciding to load a specific tool that only works on Node 16+, or it could trigger an automated rollback if the runtime falls outside a predefined safe range.

Key capabilities of this MCP server include:

• Runtime introspection: Directly queries the Node.js process for its version and environment details.
• Simple interface: Exposes a single, stateless endpoint that requires no authentication or complex payloads.
• Cross‑platform consistency: Works uniformly on Windows, macOS, and Linux environments where Node is installed.
• Extensibility: The response format can be enriched with additional metadata (e.g., installed global packages) in future iterations without breaking existing clients.

Typical use cases span the full AI development lifecycle:

• Continuous integration pipelines can automatically validate that a new build is using the correct Node.js version before deployment.
• Runtime monitoring dashboards may poll the MCP server to surface node version drift across distributed microservices.
• AI assistants that orchestrate multiple MCP tools can gate the use of certain features until the underlying runtime meets prerequisites, thereby reducing failure rates.
• Security compliance teams can audit Node.js versions across an organization’s AI infrastructure to ensure alignment with corporate policy.

By integrating this server into an MCP‑based workflow, developers gain a single source of truth for the runtime environment. It streamlines debugging, enhances reliability, and provides a foundation for automated compliance checks—all without adding complexity to the client side. The Node Version Check MCP server is therefore a valuable building block for any AI‑centric application that relies on Node.js as its runtime backbone.
