Portkey MCP Server: Bridging AI Applications with Model Context Protocol

Overview: What is Portkey MCP Server?

The Portkey MCP Server is an implementation of the Model Context Protocol (MCP), which serves as a bridge for connecting various AI tools and services to the Portkey platform. By adhering to the MCP standard, this server enables seamless integration between different AI applications and data sources, facilitating a more unified and versatile environment for AI development.

🔧 Core Features & MCP Capabilities

Portkey MCP Server supports a range of core features that enable it to function as a robust gateway in the Model Context Protocol ecosystem. Key among these is its ability to handle multiple transport protocols such as stdio (Standard Input/Output) and sse (Server-Sent Events), which cater to different use cases ranging from command-line interfaces to high-velocity data streams.

The server also supports advanced features like tool initialization and invocation through the MCP protocol, ensuring that AI applications can seamlessly interact with external tools and data sources. By supporting a wide array of capabilities, Portkey MCP Server ensures compatibility and flexibility in various development scenarios, making it an invaluable tool for developers building robust AI solutions.

⚙️ MCP Architecture & Protocol Implementation

The architecture of the Portkey MCP Server is designed to align closely with the MCP protocol's structure, ensuring seamless interoperability. At its core, the server operates as a middleware component that facilitates communication between AI applications and external tools/services by adhering to specific message formats and invocation patterns defined in the protocol.

MCP messages are structured according to JSON-RPC standards, allowing for clear and explicit interaction between client and server. The protocol flow can be visualized using the following Mermaid diagram:

This diagram illustrates how MCP clients can interact with the server and subsequently access external data sources or tools, ensuring a cohesive communication flow throughout the system.

🚀 Getting Started with Installation

To get started with Portkey MCP Server, follow these installation steps:

Local Development

For developers working locally, ensure that git hooks are installed in your repository to enforce mock regeneration before commits. Execute the following command:

cd <root-of-repo>
make install-hooks

If you encounter linting issues after this setup, use make lint-clear-cache to clear the cache.

Configuration

Portkey MCP Server supports multiple transport configurations, including stdio and sse. These configurations are typically managed via environment variables at startup. For detailed configuration information, refer to the provided .env.example file or the config package. Note that while these files serve as references, the source-of-truth remains in the config package.

To configure external deployment settings, create a .env file based on the expected variables from the config package. For Docker deployments, ensure to set environment variables appropriately through other means or use the Docker commands directly.

Running the App

Direct Go Execution

Run the Portkey MCP Server locally using:

cd <root-of-repo>
go run -ldflags="-X main.appVersion=$(git rev-parse --short HEAD)" cmd/portkey-mcp-server/main.go

This command ensures that you have the correct version information embedded in your local execution.

Binary Execution

Alternatively, build a binary for ease of use:

make build

The resulting portkey-mcp-server binary can be executed directly from the root directory without needing to recompile each time.

Running with Docker

Utilize the provided Make commands to build and run Portkey MCP Server via Docker. The following commands outline how you can start your server inside a container:

# Build the Docker image
make docker-build

# Run the container (requires PORTKEY_API_KEY)
make docker-run PORTKEY_API_KEY=your-api-key

# Additional settings for customizing port, transport mode, etc.
make docker-run PORT=9000 TRANSPORT=sse PORTKEY_API_KEY=your-api-key

You can also run it directly using Docker commands:

# Build the Docker image
docker build --build-arg APP_VERSION=$(git rev-parse --short HEAD) -t portkey-mcp-server .

# Run in SSE mode (HTTP server)
docker run -p 8080:8080 \
  -e TRANSPORT=sse \
  -e TRANSPORT_SSE_ADDRESS=:8080 \
  -e PORTKEY_API_KEY=your-api-key \
  portkey-mcp-server

💡 Key Use Cases in AI Workflows

Real-world Scenario 1: Chat Application Integration

When integrating an AI chat application with external tools and services, Portkey MCP Server ensures that the chat engine can fetch dynamic prompts from a database or other storage system. The server facilitates this by handling tool calls through the MCP protocol, ensuring the chat app has access to relevant information in real-time.

Example Workflow:

1. Chat App sends a prompt initialization request.
2. Server processes and retrieves the correct prompt based on user input.
3. Server returns the prompt back to the chat app, allowing it to render and display the message.

Real-world Scenario 2: Code Editor Integration

For an AI code editor, Portkey MCP Server serves as a bridge for fetching or modifying source code snippets from external data sources. The server ensures that the code editor can receive updated snippets seamlessly without any integration complexities.

Example Workflow:

1. Code Editor sends a request to fetch a specific code snippet.
2. Server queries the corresponding tool/database and returns the requested code snippet back to the editor's interface.
3. The code editor updates its display to show the fetched code snippet, enhancing user productivity.

🔌 Integration with MCP Clients

Portkey MCP Server supports a variety of MCP clients through its robust API integration capabilities. Here are some key integrations:

• Claude Desktop: Full support for tools and prompts.
• Continue: Full support for tools and prompts.
• Cursor: Limited support; mainly data sources and tools without prompt handling.

The following .cursor/mcp.json configuration allows you to integrate Portkey MCP Server with Cursor IDE using SSE mode:

{
  "mcpServers": {
    "Portkey": {
      "url": "http://localhost:8080/sse"
    }
  }
}

For integration via Docker, you can modify the configuration as follows:

{
  "mcpServers": {
    "Portkey": {
      "command": "docker",
      "args": [
        "run",
        "-p",
        "8080:8080",
        "--rm",
        "-e",
        "TRANSPORT",
        "-e",
        "TRANSPORT_SSE_ADDRESS",
        "-e",
        "PORTKEY_API_KEY",
        "portkey-mcp-server:latest"
      ],
      "env": {
        "TRANSPORT": "sse",
        "TRANSPORT_SSE_ADDRESS": ":8080",
        "PORTKEY_API_KEY": "your-api-key"
