Kontra Mcp
Connects Claude to structured adversarial analysis via four modes: counter (default tenth man protocol that attacks your decision), probe (pointed questions across motivation/evidence/alternatives/stakes/timing), redteam (ranked failure scenarios with likelihood and cascades), and premortem (writes the postmortem from 12 months in the future). Takes a decision statement plus optional context, returns engineered prompts that your LLM processes locally. No API keys, no external calls. Useful when you need to stress test architecture choices, strategy pivots, launch plans, or hiring decisions before consequences surface. Works through a single analyze tool with mode parameter. Quality scales with your model's capability since it's doing prompt construction, not execution.

Kontra
The Tenth Man Protocol
"If nine agree, I disagree."
An MCP tool that stress-tests your decisions with structured contrarian analysis — so blind spots surface before consequences do.
What You Get
You say:
"Use kontra to challenge this: We should rewrite our backend from Node.js to Rust. Context: Current stack is Node.js, team of 3, shipping weekly."
Kontra returns:
BLIND SPOTS
- You're measuring the cost of rewriting but not the cost of pausing. A team of 3 shipping weekly has momentum. The rewrite doesn't just cost engineering hours — it costs 3-6 months of feature development, customer feedback loops, and market positioning that your competitors won't pause for.
