概览

What is mcp-python-sdk-inmemory-server-tests?

It is an example repository with code and tests for developing robust MCP tools. It demonstrates how unit tests on individual functions can miss asynchronous pitfalls like asyncio.run in tools, and showcases a more reliable testing approach using in-memory client sessions.

How to use mcp-python-sdk-inmemory-server-tests?

Set up the environment with Node.js via Volta and uv, then run npm install and uv sync --frozen. Execute tests with uv run pytest tests/.. Debug mcpserver.py using the MCP Inspector with uv run mcp dev mcpserver.py. Format code with uv run ruff format . and uv run ruff check --select I --fix ..

常见问题

What problem does this project address?

It shows that unit tests on individual functions can miss asynchronous pitfalls like `asyncio.run` in MCP tools, and provides a better testing strategy using in-memory client sessions.

How do I run the tests?

After setup, execute `uv run pytest tests/.` in the repository root.

What is the MCP Inspector and how is it used?

The MCP Inspector is a debugging tool for MCP servers. Run `uv run mcp dev mcpserver.py` to start it and test `mcpserver.py`.

What dependencies are required?

Node.js (installed via Volta), npm, and uv (installed via shell script). After that, run `npm install` and `uv sync --frozen`.
