mcp-cli

Command-line interface for discovering and executing MCP server tools and external integrations. Access MCP servers through the command line. MCP enables interaction with external systems like GitHub, filesystems, databases, and APIs. Add -d to include descriptions (e.g., mcp-cli filesystem -d ) - Five core commands cover server discovery, tool exploration, schema inspection, execution, and grep-based searching across all available tools - Supports JSON input/output for scripting, raw text extraction, and description flags for verbose tool documentation - Handles complex JSON arguments via heredoc, stdin piping, or file input to accommodate special characters and multi-line payloads - Distinguishes exit codes by error type: client errors (1), server/tool failures (2), and network issues (3) for reliable error handling in automation - Discover : mcp-cli → see available servers and tools - Explore : mcp-cli → see tools with parameters - Inspect : mcp-cli / → get full JSON input schema - Execute : mcp-cli / ' ' → run with arguments - 0 : Success - 1 : Client error (bad args, missing config) - 2 : Server error (tool failed) - 3 : Network error
