MCP SSH is a production-grade Model Context Protocol server that provides SSH capabilities and enterprise-grade tooling. It enables executing SSH commands, transferring files, listing configured hosts, and interactive guidance via an MCP prompt. The server exposes capabilities for background execution with process tracking, chunked output retrieval, command status queries, and graceful termination. File transfers use SCP with progress reporting, while security information can be retrieved to audit configuration. It emphasizes structured JSON output for programmatic integration, and supports speed and reliability improvements through connection reuse and optimized output management. Security is configurable with modes (blacklist/whitelist/disabled) and regex-based patterns for blocked or allowed commands, enabling strict policy enforcement. Timeout and timeout-related environment variables protect against hanging operations across connection, command execution, transfers, and read operations. The stack provides host discovery via ssh://hosts and interactive help via ssh_help, and is backed by a comprehensive test suite (107 tests, extensive QA). Development and deployment tooling rely on uv, with production-ready validation and performance optimizations.
