ChainMCP

ChainMCP is a .NET-based Model Context Protocol (MCP) server implementation that provides a set of tools for handling simple operations like echoing messages and retrieving the current date and time.

Features

• Built on .NET 9
• Implements Model Context Protocol (MCP) server
• Uses standard I/O for server transport
• Includes two main tools:
  • today_tool: Returns the current date and time
  • echo_day_tool: Echoes back a provided message

Prerequisites

• .NET 9.0 SDK or later
• ModelContextProtocol package (version 0.1.0-preview.12 or compatible)

Installation

ChainMCP can be installed as an MCP server for applications like Claude Desktop or Visual Studio Code.

1. Install the tool globally using the .NET CLI:dotnet tool install --global chainmcp Or if you're installing from a local build:dotnet pack dotnet tool install --global --add-source ./chainmcp/nupkg chainmcp

2. Configure your MCP client (Claude Desktop or VS Code):

   For Claude Desktop

   Add the following to your Claude Desktop MCP configuration: { "tools": { "chainmcp": { "command": "chainmcp" } } }

   For Visual Studio Code

   Add the following to your VS Code MCP configuration: { "mcpServers": { "chainmcp": { "command": "chainmcp" } } } To update the tool to a newer version:dotnet tool update --global chainmcp To uninstall:dotnet tool uninstall --global chainmcp

Usage

The application provides two main tools that can be called from your MCP-enabled application:

Today Tool

Returns the current date and time.

Echo Tool

Echoes back the provided message.

Note: The today_tool must be called before using the echo_day_tool to obtain the correct message to echo.
