🔧 Integration Approaches

VoluteMCP offers flexible integration options for different use cases:

🌐 Cloud Integration (Serverless/Web Apps)

Best for: AWS Lambda, Vercel, Netlify, cloud-deployed AI agents

# Ultra-simple SDK integration
from volutemcp.sdk import VoluteMCPCloudClient

class MyAIAgent:
    def __init__(self):
        self.volute = VoluteMCPCloudClient()
    
    async def process_calculation(self, expression):
        return await self.volute.calculate(expression)

# Works in FastAPI, Flask, Express.js, Next.js, etc.

🖥️ Local MCP Integration (Desktop Apps)

Best for: Claude Desktop, local AI applications, PowerPoint integration, multimodal AI workflows

{
  "volutemcp-local": {
    "command": "python",
    "args": ["-m", "volutemcp.server_local", "--transport", "stdio"],
    "env": {}
  }
}

🔄 Hybrid Architecture (Best of Both)

Best for: Comprehensive AI systems needing both cloud and local capabilities, multimodal AI workflows

# Use both cloud and local servers
from volutemcp.sdk import VoluteMCPCloudClient

class HybridAIAgent:
    def __init__(self):
        self.cloud = VoluteMCPCloudClient()  # For general tools
        # Local MCP for PowerPoint (via separate config)
    
    async def process_request(self, user_input):
        # Use cloud for calculations
        if "calculate" in user_input:
            return await self.cloud.calculate("2 + 3")
        # Use local for PowerPoint (via MCP client)
        # ...

Usage Examples

Using with MCP Clients

The server can be used with any MCP-compatible client. Here are some examples:

Call a Tool

# Using an MCP client library
result = client.call_tool("calculate", {"expression": "2 + 3 * 4"})
print(result)  # 14.0

Access a Resource

# Get server config
config = client.read_resource("config://server")
print(config)

# Get specific user
user = client.read_resource("users://1")
print(user)

Use a Prompt

# Generate analysis prompt
prompt = client.get_prompt("analyze_data", {
    "data_description": "Sales data for Q1 2024",
    "analysis_type": "trends"
})

PowerPoint Analysis

# Extract comprehensive metadata from a presentation
result = client.call_tool("extract_powerpoint_metadata", {
    "presentation_path": "./presentation.pptx",
    "include_slide_content": True,
    "output_format": "json"
})

# Get a quick summary of the presentation
summary = client.call_tool("get_powerpoint_summary", {
    "presentation_path": "./presentation.pptx"
})

# Analyze specific slides only
content = client.call_tool("analyze_powerpoint_content", {
    "presentation_path": "./presentation.pptx",
    "slide_numbers": [1, 3, 5],
    "extract_text_only": True
})

# Validate a PowerPoint file
validation = client.call_tool("validate_powerpoint_file", {
    "presentation_path": "./presentation.pptx"
})

# 🆕 Capture slide images for multimodal AI analysis
slide_images = client.call_tool("capture_powerpoint_slides", {
    "presentation_path": "./presentation.pptx",
    "slide_numbers": [1, 3, 5],  # Specific slides or omit for all
    "max_slides": 10,           # Safety limit
    "image_width": 1024,        # Optional: control image size
    "image_height": 768
})
# Returns base64 PNG data URLs perfect for vision-capable AI models

Adding New Components

Add a Tool

# In tools.py
@mcp.tool(tags={"custom", "utility"})
def my_custom_tool(input_data: str) -> str:
    """My custom tool description."""
    return f"Processed: {input_data}"

Add a Resource

# In resources.py
@mcp.resource("custom://my-data")
def my_custom_resource() -> dict:
    """My custom resource description."""
    return {"data": "value"}

Add a Resource Template

# In resources.py
@mcp.resource("items://{item_id}")
def get_item(item_id: int) -> dict:
    """Get item by ID."""
    return {"id": item_id, "name": f"Item {item_id}"}

Configuration

The server uses Pydantic for configuration management. Settings can be provided via:

1. Environment variables (prefixed with VOLUTE_)
2. .env file
3. Default values in config.py

Available Settings

Setting	Default	Description
VOLUTE_NAME	VoluteMCP	Server name
VOLUTE_HOST	127.0.0.1	Server host
VOLUTE_PORT	8000	Server port
VOLUTE_LOG_LEVEL	INFO	Logging level
VOLUTE_API_KEY	None	Optional API key

Tag-Based Filtering

Filter components by tags when creating the server:

# Only expose utility tools
mcp = FastMCP(include_tags={"utility"})

# Hide internal tools
mcp = FastMCP(exclude_tags={"internal"})

# Combine filters
mcp = FastMCP(include_tags={"public"}, exclude_tags={"deprecated"})

Advanced Usage

Server Composition

from fastmcp import FastMCP
from tools import register_tools

# Create modular servers
tools_server = FastMCP("ToolsOnly")
register_tools(tools_server)

# Mount into main server
main_server = FastMCP("Main")
main_server.mount(tools_server, prefix="tools")

Custom Serialization

import yaml

def yaml_serializer(data):
    return yaml.dump(data, sort_keys=False)

mcp = FastMCP(tool_serializer=yaml_serializer)

Deployment

Docker

FROM python:3.11-slim

WORKDIR /app
COPY requirements.txt .
RUN pip install -r requirements.txt

COPY . .
