A high-precision powered exoskeleton for AI coding. Cuts 90%+ context waste via MCP: surgical AST tools, persistent Metro Map architecture, and sandboxed execution.
yubinbin32-ops/ContextOS is an MCP server distributed on github, maintained by yubinbin32-ops, tracked here since September 2026. It has shipped 20 releases and exposes 31 tools. Tools include architecture_connect, architecture_link_suggest, block_seal, chain_code_stream, change_set_revert, changes_since, and 25 more. Its composite risk grade is A — an inferred review prompt computed from observed signals, not a verdict.
Reading the source raised one review prompt — dangerous code — each a pattern worth a human look rather than a finding of fault.
