Mcp Chaining

This is a reference implementation for chaining multiple MCP tools in sequence with graceful degradation. It wires together five tools (nia for docs, ast-grep for code patterns, morph for fast search, qlty for linting, git for status) into a research-to-implementation pipeline where each step can fail independently without breaking the whole flow. The real value is seeing how to handle tool availability checks, pass environment variables correctly to subprocesses (there's a critical fix for API keys), and structure error handling so your pipeline doesn't explode when one service is down. If you're building anything that chains MCP calls, this shows the plumbing you need.
