About Test MCP
Test MCP is a minimal Python MCP server example for developers building or testing MCP projects. It includes a fuller test implementation and a smaller example, and can be run in development mode.
Key features
- 01Minimal Python MCP server example
- 02Separate full and minimal implementations
- 03Development server via `uv run fastmcp dev`
Use cases
- 01Testing MCP tool calls during development
- 02Using the examples as a starting point for MCP projects
MCP support
It is an MCP server intended for use with MCP clients. The README lists Claude Desktop, Visual Studio Code, Cline, Roo Code, Kilo Code, and Jan as clients.
Configuration
Local server config is the same for every client. Copy it into your client’s MCP config file.
We haven’t collected a package or remote endpoint for this server. Follow the instructions in the project README.
Tools
Local servers expose tools only once running on your machine, and the maintainer has not provided a tool list.

Requirements
Note: OpenRouter has many free models available that you can use for testing.
Development
For testing you can run a development server and manually run tool calls:
uv run fastmcp dev
The fully example is implemented in test-mcp.py, a minimal example you can use in your own projects is in minimal-mcp.py.
Installation
To install your MCP server you need to configure an MCP.json that looks something like this:
{
"mcpServers": {
"test-mcp": {
"command": "uv",
"args": [
"--directory",
"/Users/admin/Projects/test-mcp",
"run",
"test-mcp.py"
],
"timeout": 600
}
}
}
For Claude Desktop there is a detailed guide available.

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
