Echo MCP 服务器

echo-mcp-server-for-testing

A simple echo MCP (Model Context Protocol) Server with a simple echo_tool for testing MCP Clients. It is also great as a template for new MCP Servers.

Usage

Install uv and add the server to an MCP config using uvx:

{
    "name": "echo-mcp-server-for-testing",
    "command": "uvx",
    "args": [
        "echo-mcp-server-for-testing"
    ],
    "env": {
        "SECRET_KEY": "123456789"
    }
}

or clone the repo and use uv with a directory:

{
    "name": "echo-mcp-server-for-testing",
    "command": "uv",
    "args": [
        "--directory",
        "path/to/root/dir/",
        "run",
        "main.py"
    ],
    "env": {
        "SECRET_KEY": "123456789"
    }
}

Development

Testing

Clone the repo and use mcp-client-for-testing to test the tools of the server.

uvx mcp-client-for-testing \
    --config '
    [
        {
            "name": "echo-mcp-server-for-testing",
            "command": "uv",
            "args": [
                "--directory", 
                "path/to/root/dir/", 
                "run", 
                "main.py"
            ],
            "env": {
                "SECRET_KEY": "123456789"
            }
        }
    ]
    ' \
    --tool_call '{"name": "echo_tool", "arguments": {"message": "Hello, world!"}}'

Formatting and Linting

The code is formatted and linted with ruff:

uv run ruff format
uv run ruff check --fix

Building with uv

Releasing a New Version

To release a new version of the package to PyPI, create and push a new Git tag:

Checkout the main branch and get the current version:
git checkout main git pull origin main git describe --tags
Create and push a new Git tag:
git tag v0.2.0 git push origin v0.2.0

The GitHub Actions workflow will automatically build and publish the package to PyPI when a new tag is pushed. The python package version number will be derived directly from the Git tag.
