Mcp_server

What is Mcp_server?

Mcp_server is a MCP (Model Context Protocol) server configuration reference that demonstrates how to run MCP services using uv/uvx and connect clients via stdio, SSE, or streamable HTTP transports. It provides example configurations for multiple MCP tools such as math, weather, 12306-mcp, sequentialthinking, quickchart-server, and excel-mcp-server.

How to use Mcp_server?

Run the MCP service with uv run --with mcp[cli] mcp run path/to/mcp.py or uvx --with pillow --with mcp[cli] fastmcp run path/to/mcp.py. The service listens on port 8000 by default, offering SSE at /sse and streamable HTTP at /mcp. Configure your MCP client with one of the three transport modes (stdio, SSE, streamable HTTP) and the appropriate URL or command/args.

Key features of Mcp_server

• Supports uv/uvx for Python environment management
• Offers SSE and streamable HTTP URL modes
• Provides configuration examples for multiple MCP tools
• Supports stdio, SSE, and streamable HTTP transports
• Includes environment variable configuration for excel-mcp-server
• Uses Bearer token authentication for remote MCP services

Use cases of Mcp_server

• Run a local MCP service and connect a client via stdio
• Access the service from a Docker container using host.docker.internal
• Configure multiple MCP tools (math, weather, 12306, sequential thinking, charting, Excel) in one client
• Set environment variables like cache, log path, and retention for an Excel MCP server
• Connect to remote MCP services using SSE with Bearer token authentication

FAQ from Mcp_server

How do I start the MCP service?

Use uv run --with mcp[cli] mcp run path/to/mcp.py or uvx --with pillow --with mcp[cli] fastmcp run path/to/mcp.py.

What transport modes are supported?

The service supports stdio, SSE (Server-Sent Events), and streamable HTTP modes.

How do I configure a stdio‑based MCP client?

Use uv as the command with --directory pointing to the project root and run main.py as arguments.

Can I set environment variables for MCP tools?

Yes. The excel-mcp-server example shows variables such as LOG_PATH, CACHE_MAX_AGE, CACHE_CLEANUP_INTERVAL, LOG_RETENTION_DAYS, and LOG_CLEANUP_INTERVAL.

How do I authenticate with remote MCP services?

The sequentialthinking example uses an Authorization header with a Bearer token in the client configuration.
