GemSuite (Google Gemini) MCP server for AI agents

GemSuite MCP is a server that provides comprehensive Gemini API integration with Model Context Protocol (MCP), intelligently selecting the appropriate Gemini models based on tasks while optimizing performance and token usage. It offers specialized tools for search, reasoning, processing, and analysis, with advanced file handling capabilities.

Installation

Option 1: Using Smithery.ai (Recommended)

# Install directly via Smithery CLI
npx -y @smithery/cli@latest install @PV-Bhat/gemsuite-mcp --client claude

Option 2: Manual Installation

# Clone the repository
git clone https://github.com/PV-Bhat/gemsuite-mcp.git
cd gemsuite-mcp

# Install dependencies
npm install

# Set your Gemini API key
echo "GEMINI_API_KEY=your_api_key_here" > .env

# Build the project
npm run build

# Start the server
npm start

API Key Setup

Obtain a Gemini API key from Google AI Studio

Set it as an environment variable:

export GEMINI_API_KEY=your_api_key_here

Or create a .env file in the project root:

GEMINI_API_KEY=your_api_key_here

Using GemSuite MCP

When using GemSuite MCP with Claude or other MCP-compatible hosts, you'll have access to four specialized tools:

gem_search: For factual questions requiring search integration
gem_reason: For complex problems requiring step-by-step reasoning
gem_process: For efficient processing of text or files (most token-efficient)
gem_analyze: For detailed analysis of files with automatic model selection

Processing Files

// Summarize a document
const response = await gem_process({
  file_path: "/path/to/your/large_document.pdf",
  operation: "summarize"
});

// Extract specific information
const response = await gem_process({
  file_path: "/path/to/your/report.docx",
  operation: "extract",
  content: "Extract all financial data and metrics from this document."
});

Analyzing Files

// Analyze an image
const response = await gem_analyze({
  file_path: "/path/to/your/image.jpg",
  instruction: "Describe what you see in this image in detail."
});

// Analyze code
const response = await gem_analyze({
  file_path: "/path/to/your/code.py",
  instruction: "Identify potential bugs and suggest optimizations."
});

Complex Reasoning

// Solve a complex problem with step-by-step reasoning
const response = await gem_reason({
  problem: "Analyze this code and suggest improvements:",
  file_path: "/path/to/your/code.js",
  show_steps: true
});

// Mathematical problem solving
const response = await gem_reason({
  problem: "Solve this differential equation: dy/dx = 2xy with y(0) = 1",
  show_steps: true
});

Searching with Files

// Answer questions about a document with search integration
const response = await gem_search({
  query: "What companies are mentioned in this document?",
  file_path: "/path/to/your/document.pdf"
});

// Factual questions with search
const response = await gem_search({
  query: "What are the latest developments in quantum computing?",
  enable_thinking: true
});

Workflow Examples

Document Analysis Workflow

// 1. Get a high-level summary (most efficient)
const summary = await gem_process({
  file_path: "/path/to/large_document.pdf",
  operation: "summarize"
});

// 2. Extract specific information
const keyPoints = await gem_process({
  file_path: "/path/to/large_document.pdf",
  operation: "extract",
  content: "Extract the key findings and recommendations"
});

// 3. Answer specific questions with search integration
const answers = await gem_search({
  query: "Based on this document, what are the implications for market growth?",
  file_path: "/path/to/large_document.pdf"
});

Code Review Workflow

// 1. Get code overview
const overview = await gem_analyze({
  file_path: "/path/to/code.js",
  instruction: "Provide an overview of this code's structure and purpose"
});

// 2. Identify potential issues
const issues = await gem_reason({
  problem: "Analyze this code for bugs, security vulnerabilities, and performance issues",
  file_path: "/path/to/code.js",
  show_steps: true
});

// 3. Generate improvements
const improvements = await gem_reason({
  problem: "Suggest specific improvements to make this code more efficient and maintainable",
  file_path: "/path/to/code.js",
  show_steps: true
});

Advanced Configuration

Custom Model Selection

You can override the automatic model selection:

// Force the use of Gemini Flash Thinking for a processing task
const response = await gem_process({
  file_path: "/path/to/document.pdf",
  operation: "analyze",
  model_id: "models/gemini-2.0-flash-thinking"
});

Available Operations for gem_process

summarize: Create a concise summary
extract: Extract specific information
restructure: Reorganize content into a more useful format
simplify: Make complex content easier to understand
expand: Add detail or context to content
critique: Provide critical analysis
feedback: Offer constructive feedback
analyze: General analysis of content

How to add this MCP server to Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > MCP and click "Add new global MCP server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "cursor-rules-mcp": {
            "command": "npx",
            "args": [
                "-y",
                "cursor-rules-mcp"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explictly ask the agent to use the tool by mentioning the tool name and describing what the function does.
