Time MCP

A Model Context Protocol (MCP) server that provides time-related tools for LLM applications.

Features

• Get current UTC time in ISO 8601 format

• Get Unix timestamp

• Support for timezone queries (optional extension)

Requirements

• Node.js 18+

• pnpm

Docker Deployment

🐳 Docker 部署: 查看 DOCKER.md 了解如何使用 Docker 和 Docker Compose 部署 Time MCP 服务器。

快速开始：

docker-compose up -d

Installation

pnpm install

Development

# Run in development mode (Stdio mode)
pnpm dev

# Run in HTTP mode (development)
pnpm dev:http

# Build for production
pnpm build

# Run production build (Stdio mode)
pnpm start

# Run production build (HTTP mode)
pnpm start:http

Transport Modes

This server supports two transport modes:

Stdio Mode (Default)

The server communicates via standard input/output streams. This is the default mode and is suitable for local process communication.

pnpm dev
# or
TRANSPORT=stdio pnpm start

HTTP Mode

The server runs as an HTTP server and can be accessed remotely. Suitable for remote deployment and network communication.

# Development
pnpm dev:http

# Production
TRANSPORT=http PORT=3000 HOST=0.0.0.0 pnpm start

Environment Variables for HTTP Mode:

• TRANSPORT: Transport type (stdio | http), default: stdio

• PORT: HTTP port (HTTP mode), default: 3000

• HOST: HTTP listen address (HTTP mode), default: 0.0.0.0

• MCP_PATH or API_PATH: HTTP API path (HTTP mode), default: /mcp

• LOG_LEVEL: Log level (DEBUG | INFO | WARN | ERROR), default: INFO

Logging

The server includes comprehensive logging for troubleshooting. Logs are output to stderr (following MCP protocol conventions).

Log Levels:

• DEBUG: Detailed debug information (most verbose)

• INFO: General informational messages (default)

• WARN: Warning messages

• ERROR: Error messages only (least verbose)

Setting Log Level:

# Set log level via environment variable
LOG_LEVEL=DEBUG pnpm dev
LOG_LEVEL=ERROR pnpm start:http

What Gets Logged:

• Server startup and shutdown

• Transport creation and connection

• HTTP request/response details (method, path, duration)

• Tool calls (name, arguments, results)

• Errors with stack traces

Usage
