MCP as a Judge ⚖️

mcp-name: io.github.OtherVibes/mcp-as-a-judge

MCP as a Judge acts as a validation layer between AI coding assistants and LLMs, helping ensure safer and higher-quality code.

MCP as a Judge is a behavioral MCP that strengthens AI coding assistants by requiring explicit LLM evaluations for:

  • Research, system design, and planning
  • Code changes, testing, and task-completion verification

It enforces evidence-based research, reuse over reinvention, and human-in-the-loop decisions.

If your IDE has rules/agents (Copilot, Cursor, Claude Code), keep using them—this Judge adds enforceable approval gates on plan, code diffs, and tests.

Key problems with AI coding assistants and LLMs

  • Treat LLM output as ground truth; skip research and use outdated information
  • Reinvent the wheel instead of reusing libraries and existing code
  • Cut corners: code below engineering standards and weak tests
  • Make unilateral decisions when requirements are ambiguous or plans change
  • Security blind spots: missing input validation, injection risks/attack vectors, least‑privilege violations, and weak defensive programming

Vibe coding doesn’t have to be frustrating

What it enforces

  • Evidence‑based research and reuse (best practices, libraries, existing code)
  • Plan‑first delivery aligned to user requirements
  • Human‑in‑the‑loop decisions for ambiguity and blockers
  • Quality gates on code and tests (security, performance, maintainability)

Key capabilities

  • Intelligent code evaluation via MCP sampling; enforces software‑engineering standards and flags security/performance/maintainability risks
  • Comprehensive plan/design review: validates architecture, research depth, requirements fit, and implementation approach
  • User‑driven decisions via MCP elicitation: clarifies requirements, resolves obstacles, and keeps choices transparent
  • Security validation in system design and code changes
