Pipe-MCP MCP Server: Building Blocks for Versatile AI Application Integrations

Overview: What is Pipe-MCP MCP Server?

Pipe-MCP is a lightweight, yet powerful Model Context Protocol (MCP) server implementation designed to facilitate seamless integration of specialized tools with AI applications like Claude Desktop, Continue, Cursor, and custom applications. This document details the core features, architecture, installation process, various use cases, configuration options, and advanced setup instructions for developers looking to enhance their AI workflows.

🔧 Core Features & MCP Capabilities

Pipe-MCP offers a robust set of features that integrate well with MCP-compatible clients:

• Simple MCP Server Implementation: Built using FastMCP, making it easy to deploy and manage.
• Context Management: Efficient handling of context during the lifecycle of tool interactions.
• Diverse Transport Modes: Supports both SSE (web) and stdio (CLI) transports.
• Integrated Pipedrive CRM API Tools: Seamless integration with Pipedrive for CRM operations.

⚙️ MCP Architecture & Protocol Implementation

The Pipe-MCP server is structured to follow the Model Context Protocol (MCP), which acts as a universal adapter for AI applications. The core components include:

1. Server Core: Handles incoming requests and manages tool execution.
2. Tool Definitions: Registers tools within the server using decorators, allowing dynamic addition of custom tool functions.
3. Context Handling: Manages session state to ensure context continuity during interactions.

The protocol flow diagram illustrates how AI applications, through MCP clients, interact with Pipe-MCP server:

🚀 Getting Started with Installation

Using Local Development with uv

# Clone the repository
git clone https://github.com/yourusername/pipe-mcp.git
cd pipe-mcp

# Install dependencies using uv
uv pip install -e .

# Configure environment variables
cp .env.example .env  # Create and edit this file with your settings

Using Docker for Deployment

# Clone the repository
git clone https://github.com/yourusername/pipe-mcp.git
cd pipe-mcp

# Build the Docker image
docker build -t pipe-mcp .

# Configure environment variables in .env

💡 Key Use Cases in AI Workflows

Real-time Data Integration with Pipedrive CRM

For applications needing real-time access to customer data, Pipe-MCP enables interaction with Pipedrive through REST API calls. The server supports tools like pipedrive_get_deals and pipedrive_create_person, enriching the application’s capabilities to manage leads and contacts dynamically.

Command-Line Interface (CLI) Integration

For applications using a CLI interface, such as an AI assistant for developers, Pipe-MCP provides stdio transport, allowing seamless integration with tools written in any language. This enables complex tasks like code generation or continuous integration setup directly from the command line.

🔌 Integration with MCP Clients

SSE Configuration

Ensure your MC client is set up to connect using the following configuration:

Local Development Configuration (.mcp.json)

{
  "mcpServers": {
    "pipe-mcp": {
      "transport": "sse",
      "url": "http://localhost:8151/sse"
    }
  }
}

Python and Docker Integration

For Python and other CLI-based clients, use the following server configuration:

Python Configuration Example

{
  "mcpServers": {
    "pipe-mcp": {
      "command": "path/to/python",
      "args": ["path/to/pipe-mcp/src/main.py"],
      "env": {
        "TRANSPORT": "stdio"
      }
    }
  }
}

Docker Configuration Example

{
  "mcpServers": {
    "pipe-mcp": {
      "command": "docker",
      "args": ["run", "--rm", "-i", "pipe-mcp"],
      "env": {
        "TRANSPORT": "stdio",
        "PIPEDRIVE_API_TOKEN": "your_pipedrive_api_token"
      }
    }
  }
}

🛠️ Advanced Configuration & Security

Environmental Variables

• HOST: IP address or hostname of the server (default: 0.0.0.0).
• PORT: Port for the TCP connection.
• TRANSPORT: Specifies the transport mode, either "sse" or "stdio".
• PIPEDRIVE_API_TOKEN: API token required for Pipedrive integration.

Running the Server

To run the server using the default CLI configuration:

uv run src/server.py

For development purposes, you can also use a Docker container with this command:

docker run -d --name pipe-mcp -p 8151:8151 \
  -e HOST=0.0.0.0 \
  -e PORT=8151 \
  -e TRANSPORT=sse \
  -e PIPEDRIVE_API_TOKEN=your_pipedrive_api_token \
  pipe-mcp

❓ Frequently Asked Questions (FAQ)

Q1: Which MCP clients are compatible with Pipe-MCP?

A: Currently, Pipe-MCP is fully supported by McAfee Desktop and Continue. Cursor supports tool integration only.

Q2: Can I use Pipe-MCP server with custom protocols?

A: Yes, Pipe-MCP can be extended to support additional protocols beyond SSE and stdio through modifications in the source code.

Q3: How do I add my own tools to Pipe-MCP?

A: Define your tool functions in src/tool.py and use the @mcp.tool() decorator to register them. Ensure the context dataclass is updated as needed for new requirements.

Q4: What are the security considerations when integrating Pipedrive CRM using Pipe-MCP?

A: Always pass sensitive information like API tokens through environment variables instead of including them in the Docker image for better security practices.

Q5: Can I integrate multiple MCP clients with a single Pipe-MCP server?

A: Yes, you can define and register multiple MCP servers within one Pipe-MCP instance by specifying different host/port configurations or using unique environment variable settings.
