AI evaluation toolkit — measure inter-rater agreement across multiple LLM providers
Documentation
ConKurrence
One command. Find out if your AI agrees with itself.
ConKurrence is a statistically validated consensus measurement toolkit for AI evaluation pipelines. It uses multiple AI models as independent raters, measures inter-rater reliability with Fleiss' kappa and bootstrap confidence intervals, and routes contested items to human experts.
Install
npm install -g conkurrenceMCP Server
Use ConKurrence as an MCP server in Claude Desktop or any MCP-compatible client:
npx conkurrence mcpClaude Desktop Configuration
Add to your `claude_desktop_config.json`:
{
"mcpServers": {
"conkurrence": {
"command": "npx",
"args": ["-y", "conkurrence", "mcp"]
}
}

/plugin marketplace add AlligatorC0der/conkurrenceFeatures
- Multi-model evaluation — Run your schema against Bedrock, OpenAI, and Gemini models simultaneously
- Statistical rigor — Fleiss' kappa with bootstrap confidence intervals, Kendall's W for validity
- Self-consistency mode — No API keys needed; uses the host model via MCP Sampling
- Schema suggestion — AI-powered schema design from your data
- Trend tracking — Compare runs over time, detect agreement degradation
- Cost estimation — Know the cost before running
