Zen MCP MCP Server | MCP Server List

The ultimate development partners for your favorite Coding Agent (ClaudeOR Gemini CLI) - a Model Context Protocol server that gives you access to multiple AI models for enhanced code analysis, problem-solving, and collaborative development.

Features true AI orchestration with conversations that continue across workflows- Give Claude a complexworkflowand let it orchestrate between models automatically. Claude stays in control, performs the actual work, but gets perspectives from the best AI for each subtask. With tools like plannerfor breaking down complex projects,analyzefor understanding codebases,codereviewfor audits,refactorfor improving code structure,debugfor solving complex problems, and precommitfor validating changes, Claude can switch between different toolsandmodels mid-conversation, with context carrying forward seamlessly.
- Perform a codereview using gemini pro and o3 and use planner to generate a detailed plan, implement the fixes and do a final precommit check by continuing from the previous codereview
- This triggers a codereviewworkflow where Claude walks the code, looking for all kinds of issues
- After multiple passes, collects relevant code and makes note of issues along the way
- Maintains aconfidencelevel betweenexploring,low,medium,highandcertainto track how confidently it's been able to find and identify issues
- Generates a detailed list of critical -> low issues
- Shares the relevant files, findings, etc withGemini Proto perform a deep dive for a second codereview
- Comes back with a response and next does the same with o3, adding to the prompt if a new discovery comes to light
- When done, Claude takes in all the feedback and combines a single list of all critical -> low issues, including good patterns in your code. The final list includes new findings or revisions in case Claude misunderstood or missed something crucial and one of the other models pointed this out
- It then uses the plannerworkflow to break the work down into simpler steps if a major refactor is required
- Claude then performs the actual work of fixing highlighted issues
- When done, Claude returns to Gemini Pro for a precommitreview

All within a single conversation thread! Gemini Pro in step 11knowswhat was recommended by O3 in step 7! Taking that context and review into consideration to aid with its final pre-commit review.

Think of it as Claude CodeforClaude Code.This MCP isn't magic. It's justsuper-glue.

Remember:Claude stays in full control — butYOUcall the shots. Zen is designed to have Claude engage other models only when needed — and to follow through with meaningful back-and-forth.You'rethe one who crafts the powerful prompt that makes Claude bring in Gemini, Flash, O3 — or fly solo. You're the guide. The prompter. The puppeteer.
