Deliberation
Pull structured second opinions from GPT, Gemini, Grok, and hundreds of OpenRouter models while you stay in Claude Code or another MCP host.
Overview
Deliberation MCP is a MCP server for the Ship phase that delivers second opinions from GPT, Gemini, Grok, and 400+ OpenRouter models inside Claude Code and other MCP hosts.
What is this MCP server?
- stdio npm package @antonbabenko/deliberation-mcp at catalog version 3.5.3
- Routes deliberation requests through OpenRouter to GPT, Gemini, Grok, and 400+ other models
- Works inside Claude Code and any MCP-capable host as a second-opinion sidecar
- Useful before merging risky changes, refactors, or infra edits you only validated with one model
- Keeps your primary session in one agent while alternate models challenge assumptions
- Package @antonbabenko/deliberation-mcp version 3.5.3
- Transport: stdio via npm registry
- OpenRouter access to 400+ models including GPT, Gemini, and Grok families
What problem does it solve?
Relying on a single model for review lets consistent blind spots slip into merges because you never cross-check with a different reasoning style.
Who is it for?
Solo builders in Claude Code who want fast multi-model critique on plans, diffs, and runbooks without leaving MCP.
Skip if: Builders who cannot use OpenRouter, need guaranteed offline review, or want a fully automated CI gate with no API cost.
What do I get? / Deliverables
After you wire Deliberation MCP, you can query alternate models from the same session and incorporate dissenting views before you ship.
- Cross-model answers to focused technical questions from the active IDE session
- Documented dissent or agreement you can paste into PR description or plan
- Repeatable deliberation workflow without switching chat products
Recommended MCP Servers
Journey fit
Ship review is the canonical shelf for pre-release judgment calls—architecture, security, and diff quality—where an extra model pass reduces blind spots before you merge or deploy. Review subphase captures cross-model critique and deliberation that complements your primary coding agent without replacing your repo workflow.
How it compares
MCP multi-model deliberation layer, not a single-vendor chat skill or static linter.
Common Questions / FAQ
Who is Deliberation MCP for?
Developers using Claude Code, Cursor, or generic MCP hosts who want GPT, Gemini, Grok, or other OpenRouter models as a second opinion on technical decisions.
When should I use Deliberation MCP?
Use it during Ship review when a change is hard to unwind—security-sensitive edits, architecture shifts, or ambiguous requirements—before merge or deploy.
How do I add Deliberation MCP to my agent?
Install @antonbabenko/deliberation-mcp from npm, register the stdio server in your MCP host config, and provide OpenRouter API access per the package README.
