What is Echo MCP Server?

Echo MCP Server is a lightweight .NET Core server that implements the Model Context Protocol (MCP). It provides a single tool that echoes any message back to the client, making it a simple example of how to build a custom MCP server. It can be deployed locally or as a Docker container.

How to use Echo MCP Server?

Build from source with dotnet build src/echo.sln (requires .NET 9.0) or run a pre-built Docker image. Configure the server via appsettings.json or environment variables, then connect any MCP‑compatible client (e.g., Claude Desktop) and call the echo tool with a required message parameter.

Key features of Echo MCP Server

Echo any message back to the client
Customizable message format through MessageFormat configuration
Built on the Model Context Protocol standard
Deployable directly or as a Docker container

Use cases of Echo MCP Server

Testing and debugging MCP client integrations
Demonstrating a minimal MCP server implementation
Providing a simple echo service for prototyping

FAQ from Echo MCP Server

What prerequisites are needed to run Echo MCP Server?

For local deployment you need .NET 9.0. For container deployment you need Docker.

How can I customize the echoed message format?

Set the MessageFormat in appsettings.json (e.g., "Server says: {message}") or pass it as an environment variable MessageFormat. If not set, the default format is "Echo: {message}".

How do I configure Echo MCP Server with Claude Desktop?

Add an entry to the mcpServers section of your Claude Desktop configuration. For local use, specify command: "dotnet" with args pointing to the DLL. For Docker, set command: "docker" with args including run, --rm, -i, and -e for environment variables.

What is the default message format?

The default format is "Echo: {message}". It can be overridden via the MessageFormat setting.

Can I run Echo MCP Server using Docker?

Yes. Build the Docker image with docker build -f src/Core.Infrastructure.McpServer/Dockerfile -t echo-mcp-server:latest src/ and run it with docker run -d --name echo-mcp echo-mcp-server:latest. You can also customize the message format via environment variables or mount a custom appsettings.json.
