This server now uses the official MCP SDK for JSON-RPC handling and exposes prompts, resources, and tools via both JSON-RPC and legacy HTTP endpoints with bearer token authentication.\n\n## Project Structure\n\nThe codebase is organized into a clean, modular structure:\n\n```\n├── index.ts # Main HTTP entry point\n├── src/\n│ ├── auth/\n│ │ └── auth-manager.ts # Authentication and namespace management\n│ ├── aws/\n│ │ └── clients.ts # AWS client configuration utilities\n│ ├── mcp/\n│ │ ├── handler.ts # Main MCP request handler\n│ │ └── protocol-handlers.ts # MCP protocol-specific handlers (prompts, resources)\n│ ├── storage/\n│ │ ├── kv-store.ts # Namespaced DynamoDB key-value store\n│ │ └── files-store.ts # Namespaced S3 files store\n│ ├── tools/\n│ │ ├── definitions.ts # Tool schema definitions\n│ │ └── handlers/\n│ │ ├── index.ts # Unified tool handlers export\n│ │ ├── kv-tools.ts # Key-value store tool handlers\n│ │ ├── files-tools.ts # Files store tool handlers\n│ │ ├── code-tools.ts # Code execution tool handlers\n│ │ └── system-tools.ts # System tools using Val Town API\n│ └── valtown/\n│ └── client.ts # Val Town API client for project file access\n└── README.md\n```\n\nThis modular structure provides:\n- **Separation of concerns**: Each component has a single responsibility\n- **Easy testing**: Individual components can be tested in isolation\n- **Maintainability**: Changes to one area don't affect others\n- **Extensibility**: New tools and handlers can be easily added\n\n## Features\n\n### JSON-RPC Endpoint (Recommended)\n- **POST /mcp**: Primary JSON-RPC endpoint using MCP SDK for all operations\n- Supports all MCP operations: prompts, resources, and tools\n- Proper JSON-RPC 2.0 protocol compliance\n- Batch request support\n\n### Legacy HTTP Endpoints (Deprecated)\n- **GET /**: Server information and capabilities\n- **GET /health**: Health check endpoint\n- **GET /mcp/prompts**: List available prompts (deprecated)\n- **POST /mcp/prompts/:name**: Get specific prompt content (deprecated)\n- **GET /mcp/resources**: List S3 resources (deprecated, requires auth)\n- **GET /mcp/resources/***: Read specific S3 resource (deprecated, requires auth)\n- **GET /mcp/tools**: List available tools (deprecated)\n- **POST /mcp/tools/:name**: Execute specific tool (deprecated, requires auth)\n\n### Authentication\n\n- Uses Bearer token authentication\n- AWS_SECRET_ACCESS_KEY is passed via `Authorization: Bearer ` header\n- Other AWS credentials are configured via environment variables\n- **User Isolation**: Each bearer token creates an isolated namespace for data storage\n - KV Store operations are automatically namespaced per user\n - Files Store operations are automatically namespaced per user\n - Resources (file listings) are automatically filtered per user namespace\n- **Demo Mode**: Requests without valid authentication use a shared \"demo\" namespace with limited capabilities\n- **System Mode**: When the bearer token matches the AWS_SECRET_ACCESS_KEY environment variable, the system enters \"system mode\" with access to:\n - All regular user tools and operations\n - Special system tools for reading project source code\n - Project structure inspection capabilities\n - Enhanced debugging and administration features\n\n### Prompts\n- **analyze-data**: Analyze data from DynamoDB and S3 resources\n- **data-summary**: Generate a summary of available data sources\n\n### Resources\n- **Files**: Access and read files from your personal file store\n- Automatic MIME type detection\n- File metadata (size, last modified, version information)\n- Namespace isolation per user\n\n### Tools\n\n#### Key-Value Store Operations (Namespaced)\n- **kv-get**: Get a value by key from your personal key-value store\n- **kv-put**: Store a key-value pair in your personal key-value store\n- **kv-delete**: Delete a key-value pair from your personal key-value store\n- **kv-list**: List keys in your personal key-value store with optional prefix filter\n- **kv-query**: Query key-value pairs by key pattern from your personal key-value store\n\n#### Files Store Operations (Namespaced)\n- **files-get**: Get a file by key from your personal file store (supports versioning)\n- **files-put**: Store a file in your personal file store\n- **files-delete**: Delete a file from your personal file store (supports version-specific deletion)\n- **files-list**: List files in your personal file store with optional prefix filter\n- **files-list-versions**: List all versions of files in your personal file store\n- **files-move**: Move/rename a file within your personal file store\n- **files-copy**: Copy a file within your personal file store\n- **files-exists**: Check if a file exists in your personal file store\n- **files-metadata**: Get metadata for a file in your personal file store (supports versioning)\n\n#### Code Execution\n- **code-exec**: Execute JavaScript/TypeScript code with access to all MCP tools. Code can be provided directly as a string or referenced via files store key\n\n#### Skill Management\n- **register-skill**: Register a stored code file as a reusable skill tool with custom input schema\n- **unregister-skill**: Remove a previously registered skill\n- **list-skills**: List all registered skills for the current user\n- **[user-skills]**: Dynamically registered skills appear as individual tools with their own schemas\n\n#### System Tools (System Mode Only)\n- **system-read-file**: Read a source code file from the project using Val Town API (requires system mode access)\n- **system-list-files**: List all files in the project directory structure using Val Town API (requires system mode access)\n- **system-project-info**: Get project information and structure overview using Val Town API (requires system mode access)\n\n## Code Execution Feature\n\nThe `code-exec` tool allows you to execute JavaScript/TypeScript code with full access to all MCP tools (KV store and Files store operations). This enables powerful automation and data processing workflows.\n\n## Skill Management System\n\nThe skill management system allows you to register stored code files as reusable tools with custom input schemas. Once registered, skills appear as individual tools in the tools list and can be called like any other MCP tool.\n\n### Skill Registration\n\nUse the `register-skill` tool to register a code file as a skill:\n\n```json\n{\n \"name\": \"data-analyzer\",\n \"description\": \"Analyzes data from KV store and generates reports\",\n \"fileKey\": \"skills/data-analyzer.js\",\n \"inputSchema\": {\n \"type\": \"object\",\n \"properties\": {\n \"dataKey\": {\n \"type\": \"string\",\n \"description\": \"Key of data to analyze\"\n },\n \"reportType\": {\n \"type\": \"string\",\n \"enum\": [\"summary\", \"detailed\"],\n \"description\": \"Type of report to generate\"\n }\n },\n \"required\": [\"dataKey\"]\n }\n}\n```\n\n### Skill Management Tools\n\n- **register-skill**: Register a new skill from a files store key\n- **unregister-skill**: Remove a registered skill\n- **list-skills**: List all your registered skills\n\n### Using Registered Skills\n\nOnce registered, skills appear in the tools list and can be called directly:\n\n```json\n{\n \"jsonrpc\": \"2.0\",\n \"method\": \"tools/call\",\n \"params\": {\n \"name\": \"data-analyzer\",\n \"arguments\": {\n \"dataKey\": \"user-data-2024\",\n \"reportType\": \"detailed\"\n }\n },\n \"id\": 1\n}\n```\n\n### Code Requirements\n\nYour code must define an `async execute` function that accepts two parameters:\n- `input`: Object containing input parameters for your script\n- `tools`: Object containing all available MCP tools as callable functions\n\n```javascript\nasync function execute(input, tools) {\n // Your code logic here\n const result = await tools[\"kv-get\"]({key: input.key});\n return { message: \"Processing complete\", data: result };\n}\n```\n\n### Available Tools in Code Context\n\nWithin your executed code, you have access to all MCP tools via the `tools` object:\n- `tools[\"kv-get\"](args)` - Get from your personal key-value store\n- `tools[\"kv-put\"](args)` - Put to your personal key-value store \n- `tools[\"kv-delete\"](args)` - Delete from your personal key-value store\n- `tools[\"kv-list\"](args)` - List keys in your personal key-value store\n- `tools[\"kv-query\"](args)` - Query your personal key-value store\n- `tools[\"files-get\"](args)` - Get file from your personal file store\n- `tools[\"files-put\"](args)` - Put file to your personal file store\n- `tools[\"files-delete\"](args)` - Delete file from your personal file store\n- `tools[\"files-list\"](args)` - List files in your personal file store\n- `tools[\"files-list-versions\"](args)` - List file versions in your personal file store\n- `tools[\"files-move\"](args)` - Move file in your personal file store\n- `tools[\"files-copy\"](args)` - Copy file in your personal file store\n- `tools[\"files-exists\"](args)` - Check if file exists in your personal file store\n- `tools[\"files-metadata\"](args)` - Get file metadata from your personal file store\n\n### Two Execution Modes\n\n#### 1. Direct Code Execution\nProvide the code directly in the request:\n\n```json\n{\n \"code\": \"async function execute(input, tools) { /* your code */ }\",\n \"input\": { \"param1\": \"value1\" }\n}\n```\n\n#### 2. Files Store Code Execution \nStore your code in your personal file store and reference it by key:\n\n```json\n{\n \"key\": \"scripts/my-processor.js\",\n \"input\": { \"param1\": \"value1\" }\n}\n```\n\nThis approach is ideal for:\n- Reusable scripts and workflows\n- Version control of automation code (files store supports versioning)\n- Sharing scripts across different executions\n- Complex multi-function scripts\n- Personal script libraries isolated per user\n\n### Security Considerations\n\n- Code execution runs in a sandboxed environment\n- No access to global objects or external network calls\n- Only MCP tools are available for external operations\n- All AWS operations use the same authentication as other MCP tools\n\n## Setup\n\n### Environment Variables\n\nSet the following environment variables on your Val Town:\n\n```bash\nAWS_REGION=us-east-1\nAWS_ACCESS_KEY_ID=your-access-key-id\nS3_BUCKET=your-bucket-name\nDYNAMODB_TABLE=your-table-name\nMCP_SERVER_NAME=aws-mcp-server\nMCP_SERVER_VERSION=1.0.0\n```\n\n**Note**: `AWS_SECRET_ACCESS_KEY` is NOT set as an environment variable. Instead, it's passed via the Authorization header for security.\n\n### DynamoDB Table Schema\n\nThe KV Store requires a DynamoDB table with the following schema:\n\n**Table Configuration:**\n- **Partition Key**: `pk` (String) - Contains the user namespace\n- **Sort Key**: `sk` (String) - Contains the user's key\n- **Billing Mode**: On-demand or Provisioned (your choice)\n- **TTL**: Optional - Set TTL attribute to `ttl` if you want automatic expiration\n\n**Example AWS CLI command to create the table:**\n```bash\naws dynamodb create-table \\\n --table-name your-table-name \\\n --attribute-definitions \\\n AttributeName=pk,AttributeType=S \\\n AttributeName=sk,AttributeType=S \\\n --key-schema \\\n AttributeName=pk,KeyType=HASH \\\n AttributeName=sk,KeyType=RANGE \\\n --billing-mode PAY_PER_REQUEST\n```\n\n**Example CloudFormation template:**\n```yaml\nDynamoDBTable:\n Type: AWS::DynamoDB::Table\n Properties:\n TableName: your-table-name\n AttributeDefinitions:\n - AttributeName: pk\n AttributeType: S\n - AttributeName: sk\n AttributeType: S\n KeySchema:\n - AttributeName: pk\n KeyType: HASH\n - AttributeName: sk\n KeyType: RANGE\n BillingMode: PAY_PER_REQUEST\n TimeToLiveSpecification:\n AttributeName: ttl\n Enabled: true\n```\n\n**Data Structure:**\nEach item in the table has the following structure:\n- `pk` (String): User namespace (e.g., \"user123\", \"demo\")\n- `sk` (String): User's key (e.g., \"settings\", \"config-app\")\n- `data` (Any): The actual value stored by the user\n- `created` (String): ISO timestamp when item was created\n- `updated` (String): ISO timestamp when item was last updated\n- `ttl` (Number, Optional): Unix timestamp for automatic expiration\n\n### Deployment\n\n1. Deploy to Val Town as an HTTP val\n2. Set the required environment variables\n3. The server will be available at your Val Town URL\n\n## Usage Examples\n\n### JSON-RPC Endpoint (Recommended)\n\nAll MCP operations should now use the JSON-RPC endpoint at `POST /mcp`. This provides proper MCP protocol compliance and better error handling.\n\n#### Authentication\n\nAll authenticated requests require the Authorization header:\n\n```bash\nAuthorization: Bearer your-aws-secret-access-key\n```\n\n#### List Prompts\n\n```bash\ncurl -X POST https://your-val-town-url.web.val.run/mcp \\\n -H \"Content-Type: application/json\" \\\n -d '{\n \"jsonrpc\": \"2.0\",\n \"method\": \"prompts/list\",\n \"params\": {},\n \"id\": 1\n }'\n```\n\n#### Get Prompt Content\n\n```bash\ncurl -X POST https://your-val-town-url.web.val.run/mcp \\\n -H \"Content-Type:

Here's an example configuration:\n\n```json\n{\n \"mcpServers\": {\n \"aws-http-mcp-server\": {\n \"command\": \"node\",\n \"args\": [\"mcp-http-client.js\"],\n \"env\": {\n \"MCP_SERVER_URL\": \"https://your-val-town-url.web.val.run\",\n \"AWS_SECRET_ACCESS_KEY\": \"${AWS_SECRET_ACCESS_KEY}\"\n }\n }\n }\n}\n```\n\n## JSON-RPC Response Format\n\n### Success Response\n```json\n{\n \"jsonrpc\": \"2.0\",\n \"result\": {\n \"content\": [\n {\n \"type\": \"text\",\n \"text\": \"Response content here\"\n }\n ]\n },\n \"id\": 1\n}\n```\n\n### Error Response\n```json\n{\n \"jsonrpc\": \"2.0\",\n \"error\": {\n \"code\": -32603,\n \"message\": \"Error message description\"\n },\n \"id\": 1\n}\n```\n\n## JSON-RPC Error Codes\n\n- `-32700`: Parse error (Invalid JSON)\n- `-32600`: Invalid Request\n- `-32601`: Method not found\n- `-32602`: Invalid params\n- `-32603`: Internal error\n- `-32001`: Authentication error (custom)\n\n## Security Considerations\n\n- **Bearer Token Authentication**: AWS_SECRET_ACCESS_KEY is passed via Authorization header, not stored in environment variables\n- **HTTPS Only**: Always use HTTPS in production to protect the bearer token\n- **IAM Permissions**: Use IAM roles with minimal required permissions\n- **Token Rotation**: Regularly rotate your AWS secret access keys\n- **Rate Limiting**: Consider implementing rate limiting for production use\n\n## Required AWS Permissions\n\n### S3 Permissions\n```json\n{\n \"Version\": \"2012-10-17\",\n \"Statement\": [\n {\n \"Effect\": \"Allow\",\n \"Action\": [\n \"s3:GetObject\",\n \"s3:PutObject\",\n \"s3:DeleteObject\",\n \"s3:ListBucket\"\n ],\n \"Resource\": [\n \"arn:aws:s3:::your-bucket-name\",\n \"arn:aws:s3:::your-bucket-name/*\"\n ]\n }\n ]\n}\n```\n\n### DynamoDB Permissions\n```json\n{\n \"Version\": \"2012-10-17\",\n \"Statement\": [\n {\n \"Effect\": \"Allow\",\n \"Action\": [\n \"dynamodb:GetItem\",\n \"dynamodb:PutItem\",\n \"dynamodb:DeleteItem\",\n \"dynamodb:Query\"\n ],\n \"Resource\": \"arn:aws:dynamodb:region:account:table/your-table-name\"\n }\n ]\n}\n```\n\n**Note**: The KV Store uses DynamoDB Query operations with a composite key structure (partition key + sort key) for efficient namespace isolation and prefix matching. Scan operations are not required.\n\n## Error Handling\n\nThe server includes comprehensive error handling for:\n- Missing or invalid Authorization headers\n- AWS service errors\n- Invalid parameters\n- Network connectivity issues\n- JSON-RPC protocol errors\n\n### JSON-RPC Errors\nAll JSON-RPC errors follow the standard format with appropriate error codes.\n\n### Legacy HTTP Errors\nLegacy endpoints return errors with HTTP status codes:\n- `401`: Authentication errors\n- `400`: Bad request (invalid parameters)\n- `404`: Resource or tool not found\n- `500`: Server errors (AWS service errors, etc.)\n\n## Legacy API Response Format (Deprecated)\n\n### Success Response\n```json\n{\n \"content\": [\n {\n \"type\": \"text\",\n \"text\": \"Response content here\"\n }\n ]\n}\n```\n\n### Error Response\n```json\n{\n \"error\": \"Error message description\"\n}\n```\n\n## Health Check\n\nThe server provides a health check endpoint:\n\n```bash\ncurl https://your-val-town-url.web.val.run/health\n```\n\nResponse:\n```json\n{\n \"status\": \"healthy\",\n \"timestamp\": \"2024-01-01T00:00:00.000Z\"\n}\n```\n\n## System Mode Tools\n\nWhen the bearer token matches the AWS_SECRET_ACCESS_KEY environment variable, the system enters \"system mode\" and provides additional tools for project inspection and debugging using the Val Town API:\n\n### System Tools Usage Examples\n\n```bash\n# Read a project source file using Val Town API\ncurl -X POST https://your-val-town-url.web.val.run/mcp \\\n -H \"Content-Type: application/json\" \\\n -H \"Authorization: Bearer your-aws-secret-access-key\" \\\n -d '{\n \"jsonrpc\": \"2.0\",\n \"method\": \"tools/call\",\n \"params\": {\n \"name\": \"system-read-file\",\n \"arguments\": {\n \"path\": \"src/auth/auth-manager.ts\"\n }\n },\n \"id\": 1\n }'\n\n# List project files recursively using Val Town API\ncurl -X POST https://your-val-town-url.web.val.run/mcp \\\n -H \"Content-Type: application/json\" \\\n -H \"Authorization: Bearer your-aws-secret-access-key\" \\\n -d '{\n \"jsonrpc\": \"2.0\",\n \"method\": \"tools/call\",\n \"params\": {\n \"name\": \"system-list-files\",\n \"arguments\": {\n \"path\": \"/src\",\n \"recursive\": true\n }\n },\n \"id\": 1\n }'\n\n# Get comprehensive project information using Val Town API\ncurl -X POST https://your-val-town-url.web.val.run/mcp \\\n -H \"Content-Type: application/json\" \\\n -H \"Authorization: Bearer your-aws-secret-access-key\" \\\n -d '{\n \"jsonrpc\": \"2.0\",\n \"method\": \"tools/call\",\n \"params\": {\n \"name\": \"system-project-info\",\n \"arguments\": {}\n },\n \"id\": 1\n }'\n```\n\n### System Mode Security\n\n- System mode is only activated when the bearer token exactly matches the AWS_SECRET_ACCESS_KEY environment variable\n- System tools provide read-only access to project files and structure via Val Town API\n- No write operations are permitted through system tools\n- System mode enables debugging and administration without compromising user data isolation\n- All file access is handled through Val Town's secure API infrastructure\n```",[],[356],{"_104":366,"_95":99,"_153":367,"_155":-5,"_156":138,"_157":368,"_159":22,"_106":369,"_100":370,"_162":371,"_164":372,"_165":22,"_166":-5,"_167":373,"_98":374},"4dc7517a-4907-11f0-8846-76b3cceeab13","6e010d7c-45d4-11f0-a0c9-76b3cceeab13",311,["D",1749895616689],40,"http","/**\n * Remote HTTP Model Context Protocol (MCP) Server\n * Uses streamable HTTP transport with raw Web API\n * Exposes prompts, S3 resources, and tools for DynamoDB/S3 operations\n */\n\nimport { AuthManager, ExtendedAuthContext } from \"./src/auth/auth-manager.ts\";\nimport { MCPHandler } from \"./src/mcp/handler.ts\";\n\n// Environment variables\nconst MCP_SERVER_NAME = Deno.env.get(\"MCP_SERVER_NAME\") || \"aws-mcp-server\";\nconst MCP_SERVER_VERSION = Deno.env.get(\"MCP_SERVER_VERSION\") || \"1.0.0\";\n\nconst mcpHandler = new MCPHandler();\nconst authManager = new AuthManager();\n\n// Authentication function for MCP requests\nfunction authenticateRequest(request: Request): string | null {\n const authHeader = request.headers.get(\"Authorization\");\n\n if (!authHeader || !authHeader.startsWith(\"Bearer \")) {\n return null;\n }\n\n const awsSecretAccessKey = authHeader.substring(7); // Remove \"Bearer \" prefix\n\n if (!awsSecretAccessKey) {\n return null;\n }\n\n return awsSecretAccessKey;\n}\n\n// Create JSON-RPC error response\nfunction createErrorResponse(id: any, code: number, message: string): Response {\n return new Response(\n JSON.stringify({\n jsonrpc: \"2.0\",\n id,\n error: {\n code,\n message,\n },\n }),\n {\n status: code === -32001 ?
