🧠 MCP Server Helm Chart

This Helm chart dynamically deploys an MCP (Model Context Protocol) server, accessible remotely via Server-Sent Events (SSE). It allows you to easily expose any existing REST API from your application as tools within the MCP environment, enabling intelligent agents or external clients to query and use them.

🚀 Features

• Deploy an MCP server in a Kubernetes cluster
• Enable remote interaction via SSE
• Dynamically register and expose API endpoints as tools
• Lightweight configuration via values.yaml
• Compatible with FastAPI, Express, Flask, and any REST service

⚙️ Dynamic Configuration

You can define which APIs to expose directly in your values.yaml file using the config.tools section. Here's an example configuration:

config:
  tools: |
    tools:
      get_api_status:
        endpoint: https://api-users.dev.example.com/
        description: Get root message to verify the API is running.

      fetch_user_by_id:
        endpoint: https://api-users.dev.example.com/users/1
        description: Fetch a specific user by ID from the API.

      get_random_user:
        endpoint: https://api-users.dev.example.com/users/random
        description: Retrieve a randomly selected user (for testing/demo).

🔒 Make sure to replace *.dev.example.com with your actual domains.

🧪 Install the Chart

helm install mcp-server ./mcp-server \
  --values values.yaml

🔌 MCP Client Configuration

Once deployed, clients can connect to your MCP server using the following configuration:

{
  "mcp": {
    "servers": {
      "users-api": {
        "url": "https://mcp-server.dev.example.com/sse"
      }
    }
  }
}

🔁 The MCP server uses SSE (/sse) to stream messages in real-time.

🧹 Uninstall

helm uninstall mcp-server

🧠 About MCP

MCP (Model Context Protocol) is a lightweight interaction layer that enables intelligent agents or applications to access domain-specific tools using natural language interfaces or direct API querying.
