Amazon VPC Lattice MCP Server

A Model Context Protocol (MCP) server for source listing, providing tools for accessing and managing AWS VPC Lattice resources and related documentation.

Features

The server provides five main tools:

list_sources: Lists all available sources with their URLs and sample prompts
get_source_prompts: Gets sample prompts for a specific source
list_amazon_vpc_lattice_prompts: Lists all available prompt templates
get_amazon_vpc_lattice_prompts: Gets details of a specific prompt template
vpc_lattice_cli: Execute AWS CLI VPC Lattice commands for managing VPC Lattice resources

Installation

This project is built with TypeScript and uses ES modules. Note that installing github-mcp-server is also strongly recommended to assist with development prompts.

Clone the repository:

git clone https://github.com/awslabs/amazon-vpc-lattice-mcp-server.git
cd amazon-vpc-lattice-mcp-server

Install dependencies:

npm install

Build the server:

npm run build

The build script will compile the TypeScript code and set the appropriate executable permissions.

Configuration

Add the server to your MCP settings file (located at ~/Library/Application Support/Code/User/globalStorage/asbx.amzn-cline/settings/cline_mcp_settings.json):

{
  "mcpServers": {
    "amazon-vpc-lattice": {
      "command": "node",
      "args": ["/path/to/amazon-vpc-lattice-mcp-server/build/index.js"],
      "disabled": false,
      "autoApprove": [],
      "env": {}
    }
  }
}

Usage

Once configured, you can use the MCP tools in your conversations. Note that you should use list_amazon_vpc_lattice_prompts to discover available prompts as these are not automatically discoverable like tools.

List Sources

use_mcp_tool({
  server_name: "amazon-vpc-lattice",
  tool_name: "list_sources",
  arguments: {}
})

Get Source Prompts

use_mcp_tool({
  server_name: "amazon-vpc-lattice",
  tool_name: "get_source_prompts",
  arguments: {
    source_name: "AWS Documentation"
  }
})

List Amazon VPC Lattice Prompts

use_mcp_tool({
  server_name: "amazon-vpc-lattice",
  tool_name: "list_amazon_vpc_lattice_prompts",
  arguments: {}
})

Get Amazon VPC Lattice Prompt Details

use_mcp_tool({
  server_name: "amazon-vpc-lattice",
  tool_name: "get_amazon_vpc_lattice_prompts",
  arguments: {
    prompt_name: "setup_eks_controller"
  }
})

VPC Lattice CLI

The vpc_lattice_cli tool provides a programmatic interface to AWS VPC Lattice operations through the AWS CLI.

Features

Supports all major VPC Lattice CLI operations
Accepts command arguments as JavaScript objects
Automatically converts camelCase parameters to CLI-style kebab-case
Handles boolean flags, arrays, and complex values
Supports AWS profiles and region configuration
Returns parsed JSON responses

Available Commands

Service Network: create-service-network, delete-service-network, get-service-network, list-service-networks, update-service-network
Service: create-service, delete-service, get-service, list-services, update-service
Listener: create-listener, delete-listener, get-listener, list-listeners, update-listener
Rule: create-rule, delete-rule, get-rule, list-rules, update-rule

Examples

List service networks:

use_mcp_tool({
  server_name: "amazon-vpc-lattice",
  tool_name: "vpc_lattice_cli",
  arguments: {
    command: "list-service-networks",
    region: "us-west-2"
  }
})

Create a service network:

use_mcp_tool({
  server_name: "amazon-vpc-lattice",
  tool_name: "vpc_lattice_cli",
  arguments: {
    command: "create-service-network",
    args: {
      name: "my-network",
      authType: "NONE"
    }
  }
})

Create a service with tags:

use_mcp_tool({
  server_name: "amazon-vpc-lattice",
  tool_name: "vpc_lattice_cli",
  arguments: {
    command: "create-service",
    args: {
      name: "my-service",
      serviceNetworkIdentifier: "sn-12345",
      tags: [
        { key: "Environment", value: "Production" }
      ]
    }
  }
})

Create a target group:

use_mcp_tool({
  server_name: "amazon-vpc-lattice",
  tool_name: "vpc_lattice_cli",
  arguments: {
    command: "create-target-group",
    args: {
      name: "my-target-group",
      type: "INSTANCE",
      config: {
        port: 80,
        protocol: "HTTP",
        healthCheck: {
          enabled: true,
          protocol: "HTTP",
          path: "/health"
        }
      }
    }
  }
})

Development

Project Structure

The project is organized as follows:

src/index.ts: Main server setup and initialization
src/tools.ts: Tool definitions and handlers
src/data/: Data files
- prompts.ts: Prompt templates and parameters
- sources.ts: Source definitions and their prompts
package.json: Project configuration and dependencies
tsconfig.json: TypeScript configuration
.gitignore: Git ignore rules
build/: Compiled JavaScript output

Adding New Sources

To add new sources, modify the sources array in src/data/sources.ts:

export const sources = [
  {
    name: 'Your Source',
    url: 'https://your-source-url.com',
    prompts: [
      'Sample prompt 1 {placeholder}',
      'Sample prompt 2 {placeholder}'
    ]
  }
  // ... existing sources
];

Adding New Prompts

To add new prompt templates, modify the prompts array in src/data/prompts.ts:

export const prompts = [
  {
    name: 'Your Prompt Template',
    description: 'Description of what the prompt does',
    template: 'Your prompt template with {parameter} placeholders',
    parameters: ['parameter']
  }
  // ... existing prompts
];

Scripts

npm run build: Build the server and set executable permissions
npm run watch: Watch mode for development
npm test: Run tests (currently not implemented)
