### Description (declared)

# mcp-tuning

A **script-first** MCP debugging/testing library for Jupyter notebooks and plain Python scripts.

It is designed to help you iterate on MCP servers (implemented in any language) by providing a small, synchronous client API:

- Connect via `stdio` (subprocess), `http`, or `sse`
- Explore: tools / resources / prompts
- Call tools with JSON arguments
- Save/replay input-only cases (tool + args)
- Export logs / history / last result as JSON for repeatable debugging

Start with `examples/notebooks/01_mcp_inspector_demo.ipynb`.

## Requirements

- Python 3.12+
- `uv`

## Install (uv)

```powershell
uv sync
uv sync --extra notebook --extra test
```

## Run (Jupyter)

```powershell
uv run jupyter lab
```

## Quickstart (stdio)

Prefer argv lists for `stdio` servers (avoids shell quoting issues) and make sure the server runs in an environment that has its dependencies installed.

```python
from mcp_tuning import connect_stdio

# Example 1: connect to the built-in mock server (minimal dependencies)
import sys
c = connect_stdio([sys.executable, "src/mcp_tuning/_mock_server.py"])

print(c.server_info())
print([t.name for t in c.tools()])
print(c.call("add", {"a": 1, "b": 2}).result)
c.close()
```

Connect to the FastMCP example server (requires `mcp` installed in the interpreter that runs the server):

```python
from mcp_tuning import connect_stdio

c = connect_stdio([".venv/Scripts/python.exe", "examples/servers/simple_stdio_server.py"])
print([t.name for t in c.tools()])
print(c.call("add", {"a": 1, "b": 2}).result)
c.close()
```

## Public API Reference

The public API is intentionally small and exported at the top-level `mcp_tuning` package.

### Connect functions

- `connect_stdio(command, *, cwd=None, env=None) -> Client`
  - `command`: `list[str]` (recommended) or `str`
  - defaults to running the subprocess with the repo root as `cwd` (more reliable in notebooks)
- `connect_http(rpc_url, *, headers=None) -> Client`
- `connect_sse(*, sse_url, rpc_url, head…
