Gemini CLI Orchestrator MCP

# Gemini CLI Orchestrator v2.0 - Sequential Thinking MCP A metaprompting-first MCP server that guides AI agents through intelligent, multi-step codebase analysis using Google's Gemini AI. ## 🧠 Core Philosophy **Don't build intelligence into the system. Build prompts that elicit intelligence from the agent.** This tool doesn't wrap or replace your thinking - it guides you to think more systematically about complex codebase analysis through structured workflows. ## 🚀 Quick Start **Step 1: Install Gemini CLI** ```bash npm install -g @google/gemini-cli ``` **Step 2: Authenticate (one-time setup)** ```bash gemini auth login ``` **Step 3: Install this tool** ```bash npm install ``` **Step 4: Test it works** ```bash node gemini-collaboration-guide.mjs ``` **Step 5: Try your first analysis** (using Claude Code CLI) ```bash # Start with planning a simple analysis gemini_plan_analysis goal="Understand this project's main architecture" # Then craft a specific prompt for the first step gemini_craft_prompt step_description="Analyze package.json and README for project overview" context="Starting fresh analysis" ``` That's it! Authentication is handled automatically by the gemini CLI. ## How It Works Instead of trying to be "smart" about your analysis, this tool provides four simple tools that guide you through systematic analysis: ### 🎯 `gemini_plan_analysis(goal)` Breaks down complex analysis goals into a step-by-step plan. Be specific about what you want to understand and why. **Example:** ```bash gemini_plan_analysis goal="Audit authentication system for security vulnerabilities" ``` ### 🔍 `gemini_craft_prompt(step_description, context)` Helps you write better prompts for Gemini by suggesting effective commands and context for each analysis step. **Example:** ```bash gemini_craft_prompt step_description="Analyze JWT token handling" context="Found 3 auth endpoints, focusing on token security" ``` ### 🔄 `gemini_iterate_analysis(current_understanding, iteration_goal)` Guide iterative analysis using observe-think-act cycles for dynamic problem-solving. **Example:** ```bash gemini_iterate_analysis current_understanding="Found potential SQL injection in login" iteration_goal="Investigate if other endpoints have similar issues" ``` ### 📊 `gemini_synthesize_findings(steps_summary, synthesis_goal)` Combine insights from multiple analysis steps into comprehensive understanding. **Example:** ```bash gemini_synthesize_findings steps_summary="Analyzed auth system, found 2 vulnerabilities, tested 5 endpoints" synthesis_goal="Create security audit report with prioritized fixes" ``` ## Example Workflow Here's how you'd conduct a security audit using the orchestrator: ```bash # 1. Plan the overall analysis gemini_plan_analysis goal="Analyze authentication system for security vulnerabilities" # → Outputs: 5-stage analysis plan with specific steps # 2. Execute each planned step gemini_craft_prompt step_description="Identify authentication mechanisms" context="Security audit of auth system" # → Outputs: Optimized gemini command to analyze auth files # → You run: cat src/auth/**/* | gemini -m gemini-2.5-flash -p "..." # 3. Dive deeper if needed gemini_iterate_analysis current_understanding="Found JWT + session auth" iteration_goal="Check for common auth vulnerabilities" # → Outputs: ReAct loop guidance for systematic vulnerability testing # 4. Synthesize final report gemini_synthesize_findings steps_summary="Analyzed 3 auth mechanisms, found 2 issues" synthesis_goal="Security audit report with fixes" # → Outputs: Comprehensive synthesis strategy for final report ``` ## 🎯 Key Benefits ✅ **Simplified Authentication** - Uses your existing gemini CLI setup ✅ **True Metaprompting** - Guides your intelligence, doesn't replace it ✅ **Multi-Step Analysis** - Break complex problems into manageable steps ✅ **Flexible Workflows** - Adapt your approach based on what you discover ✅ **Direct Gemini Integration** - No wrapper complexity or auth overhead ## 📚 Documentation - **[How It Works](docs/HOW_IT_WORKS.md)** - Deep dive into the architecture and metaprompting philosophy - **[Contributing Guide](docs/CONTRIBUTING.md)** - How to contribute to the project - **[Code of Conduct](CODE_OF_CONDUCT.md)** - Community standards and expectations ## 🤝 Contributing We welcome contributions!

The filename was renamed to `gemini-collaboration-guide.mjs` for clarity. **See "Handling Previous Installations" below** if you encounter setup issues. ### Claude Code CLI (Recommended) The easiest and most reliable way to configure the MCP server: ```bash # Add the server using Claude Code's built-in command claude mcp add gemini-collaboration-guide node /path/to/your/gemini-cli-orchestrator/gemini-collaboration-guide.mjs # Verify it was added claude mcp list # Test it's working in Claude Code /mcp ``` **Important:** - Use the full absolute path to the `gemini-collaboration-guide.mjs` file - The server name must be exactly `gemini-collaboration-guide` - Restart Claude Code after adding the server ### Handling Previous Installations / Filename Changes If you previously configured this MCP server or encounter issues like "Status: ✘ failed", follow these steps: ```bash # 1. Remove any old configurations claude mcp remove gemini-cli-orchestrator # Old name claude mcp remove gemini-orchestrator # Another old name claude mcp remove gemini-collaboration-guide # Clean slate # 2. Verify clean state claude mcp list # 3. Add with correct filename (use YOUR actual path) claude mcp add gemini-collaboration-guide node /Users/dannynguyen/gemini-cli-orchestrator/gemini-collaboration-guide.mjs # 4. Restart Claude Code completely # 5. Test it works /mcp ``` ### Manual Configuration (Alternative) If you prefer manual JSON configuration: **Claude Desktop** - Config file: `~/Library/Application Support/Claude/claude_desktop_config.json` ```json { "mcpServers": { "gemini-collaboration-guide": { "command": "node", "args": ["/absolute/path/to/your/gemini-cli-orchestrator/gemini-collaboration-guide.mjs"] } } } ``` **Cursor IDE** - Config file: `.cursor/mcp.json` ```json { "mcpServers": { "gemini-collaboration-guide": { "command": "node", "args": ["/absolute/path/to/your/gemini-cli-orchestrator/gemini-collaboration-guide.mjs"] } } } ``` **Windsurf IDE** - Config file: `windsurf_config.json` ```json { "mcpServers": { "gemini-collaboration-guide": { "command": "node", "args": ["/absolute/path/to/your/gemini-cli-orchestrator/gemini-collaboration-guide.mjs"], "disabled": false, "alwaysAllow": [] } } } ``` ### Troubleshooting **If `/mcp` shows "No MCP servers configured" or tools aren't available:** 1. **Check for filename/configuration conflicts** (Most Common Issue) - Follow the "Handling Previous Installations" section above - The file was renamed from `gemini-orchestrator.mjs` to `gemini-collaboration-guide.mjs` 2. **Clean setup process**: ```bash # Remove all old configurations claude mcp remove gemini-cli-orchestrator claude mcp remove gemini-orchestrator claude mcp remove gemini-collaboration-guide # Add with correct filename claude mcp add gemini-collaboration-guide node /absolute/path/to/gemini-collaboration-guide.mjs ``` 3. **Verify the file exists**: ```bash ls -la /path/to/your/gemini-cli-orchestrator/gemini-collaboration-guide.mjs ``` 4. **Test the server can start**: ```bash node /path/to/your/gemini-cli-orchestrator/gemini-collaboration-guide.mjs --help ``` 5. **Restart Claude Code** completely after any configuration changes 6. **Verify success**: ```bash claude mcp list # Should show: gemini-collaboration-guide /mcp # Should show the four tools ``` **Common Errors:** - `Status: ✘ failed` → Usually wrong filename (use `gemini-collaboration-guide.mjs`) - `File does not exist` → Check absolute path is correct - Tools not appearing → Restart Claude Code after configuration ## Advanced Usage Examples ### Security Audit Workflow ``` 1.
