Kontra Mcp
Stress-test product, pricing, and launch decisions with structured devil’s-advocate analysis inside your coding agent.
Overview
Kontra MCP is an MCP server for the Validate phase that runs Tenth Man–style contrarian analysis (counter, probe, red team, pre-mortem) on decisions you describe to your agent.
What is this MCP server?
- Tenth Man Protocol: mandated opposing viewpoint on plans and assumptions
- Four analysis modes: counter, probe, redteam, and premortem via KONTRA_DEFAULT_MODE
- stdio MCP server (npm kontra-mcp v0.1.2) for Claude Code, Cursor, and compatible agents
- Configurable log verbosity (debug|info|warn|error) for local debugging
- Decision-maker focused output—not generic chat opinions
- 4 analysis modes: counter, probe, redteam, premortem
- Package version 0.1.2 on npm (kontra-mcp)
- stdio transport via Model Context Protocol

What problem does it solve?
You keep green-lighting ideas because your AI assistant agrees with everything and nobody argues the downside before you build.
Who is it for?
Indie founders and solo builders who want a formal devil’s advocate pass on roadmap, pricing, or launch decisions inside MCP-enabled agents.
Skip if: Teams that already run formal red-team reviews with humans, or builders who only need factual research without decision framing.
What do I get? / Deliverables
You get documented opposing scenarios, probes, and pre-mortem risks so scope and launch calls reflect structured dissent—not groupthink.
- Structured contrarian analysis in the agent thread for a stated decision
- Mode-specific critique (counter, probe, redteam, or premortem)
- Repeatable decision ritual you can invoke before scope lock
Recommended MCP Servers
Journey fit
Canonical shelf is validate because solo builders need contrarian review while scoping commitments, before they over-build. Scope is where tradeoffs, roadmaps, and go/no-go calls get locked; Kontra is built for that decision layer.
How it compares
Structured decision-analysis MCP, not a web search or analytics dashboard skill.
Common Questions / FAQ
Who is kontra-mcp for?
Solo builders and decision-makers using Claude Code, Cursor, or other MCP clients who want mandatory contrarian takes before committing to a plan.
When should I use kontra-mcp?
Use it when scoping a feature, validating pricing, or prepping a launch—especially when every stakeholder (including your agent) seems aligned.
How do I add kontra-mcp to my agent?
Add the npm package kontra-mcp as a stdio MCP server in your client config, set KONTRA_DEFAULT_MODE if desired, and restart the agent session.
