Tetrad
Run a four-model consensus pass on a code change so Codex, Gemini, and Qwen critiques surface agreement and disagreements before you merge.
Overview
Tetrad is a MCP server for the Ship phase that runs quadruple consensus code validation using Codex, Gemini, and Qwen.
What is this MCP server?
- Quadruple consensus validation across Codex, Gemini, and Qwen model backends
- Published as npm package @samoradc/tetrad v0.1.12 with stdio MCP transport
- MCP server purpose-built for code validation, not generic chat
- Fits pre-merge and PR-review workflows inside agent-driven development
- Open source on GitHub at SamoraDC/Tetrad
- Server version 0.1.12
- 1 npm package @samoradc/tetrad
- 4-model consensus positioning (quadruple consensus with Codex, Gemini, and Qwen)
Community signal: 1 GitHub stars.
What problem does it solve?
One coding agent can approve flawed logic because a single model miss is easy to trust when you are shipping under time pressure.
Who is it for?
Indie developers who already use multiple LLM APIs and want an MCP-native ensemble review step on critical patches.
Skip if: Teams that only want linting and CI, or builders who cannot configure access to the Codex, Gemini, and Qwen backends Tetrad orchestrates.
What do I get? / Deliverables
After registration, you can invoke consensus validation from your agent and compare multi-model findings before you merge or release.
- Consensus-oriented validation output aggregating multiple model perspectives on submitted code
- Stdio MCP integration for agent-triggered review sessions
- Repeatable multi-model critique workflow without manual copy-paste across chats
Recommended MCP Servers
Journey fit
Multi-model validation belongs in Ship when you are hardening changes and want an extra review gate beyond a single LLM opinion. Review is the right shelf because Tetrad orchestrates parallel model judgments on code rather than authoring features or deploying binaries.
How it compares
Multi-LLM consensus MCP validator, not a unit-test runner or static analyzer skill.
Common Questions / FAQ
Who is Tetrad for?
Tetrad is for solo builders and small teams who want several large models to independently judge the same code change through one MCP server.
When should I use Tetrad?
Use it in the ship and review step when a change is merge-ready but you want extra model diversity on correctness, safety, or API misuse before you commit.
How do I add Tetrad to my agent?
Install @samoradc/tetrad from npm, configure provider credentials per the GitHub repo, and register the stdio MCP server in Claude Code, Cursor, or your MCP client.
