NASA-MCP-server

The server uses `dotenv` for environment variable management and `zod` for robust input validation, which are good security practices. API keys are expected via environment variables or command-line arguments, preventing hardcoding. External API requests include timeouts. Dynamic module imports for handlers are used but appear to be constrained by a predefined set of tool names, reducing the risk of arbitrary code execution. Minor concerns exist regarding the direct manipulation of the global object for registering MCP tools, although the naming convention (`mcp__nasa...`) limits potential collisions. Overall, solid security hygiene for an API proxy.
