## What it does

The skill covers the join between the MCP Python client and DSPy. You open a `ClientSession`, pull the tool list with `list_tools()`, and wrap each entry via `dspy.Tool.from_mcp_tool`. Those tools then go into `dspy.ReAct`, which picks them as it works through a task.

Two runnable examples ship with it: a streamable HTTP server at `http://localhost:8000/mcp` and a local stdio server built from `StdioServerParameters`. Both are asyncio-based, so the agent has to be driven with `acall()` rather than a plain call. The session gets initialized before `list_tools()`.

One thing to watch: DSPy converts tools but leaves connection handling to you. The `ClientSession` has to stay open for as long as the `dspy.Tool` objects derived from it are in use — close it early and the calls fail. Installation pulls the `dspy[mcp]` extra, version 3.2.1 up to 3.3.

## When to use it
- hook an MCP server up to a DSPy agent
- convert MCP tools into `dspy.Tool` objects
- build a ReAct agent on top of MCP tools
- launch a local stdio MCP server from Python
- call async MCP tools through `acall()`

## Example prompts
- Connect the MCP server at `http://localhost:8000/mcp` and wrap its tools as `dspy.Tool`
- Build a ReAct agent with the MCP tools and `max_iters=5`
- Start a local stdio MCP server and hand its tools to DSPy

# DSPy MCP Tool Integration

## Goal

Connect an MCP server with the MCP Python client, convert its tools to `dspy.Tool`, and use them in an async DSPy agent.

## Install

```bash
pip install -U "dspy[mcp]>=3.2.1,<3.3"
```

DSPy converts tools but does not manage MCP connections. Keep the `ClientSession` alive for as long as the DSPy tools are in use.

## Streamable HTTP Server

```python
import asyncio
import dspy
from mcp import ClientSession
from mcp.client.streamable_http import streamablehttp_client

async def main():
    async with streamablehttp_client("http://localhost:8000/mcp") as (read, write):
        async with ClientSession(read, write) as session:
            await session.initialize()
            response = await session.list_tools()
            tools = [dspy.Tool.from_mcp_tool(session, tool) for tool in response.tools]

            agent = dspy.ReAct("task -> result", tools=tools, max_iters=5)
            output = await agent.acall(task="Check the weather in Tokyo")
            print(output.result)

asyncio.run(main())
```

## Local Stdio Server

```python
import asyncio
import dspy
from mcp import ClientSession, StdioServerParameters
from mcp.client.stdio import stdio_client

async def main():
    params = StdioServerParameters(
        command="python3",
        args=["path/to/server.py"],
        env=None,
    )

    async with stdio_client(params) as (read, write):
        async with ClientSession(read, write) as session:
            await session.initialize()
            response = await session.list_tools()
            tools = [dspy.Tool.from_mcp_tool(session, tool) for tool in response.tools]
            agent = dspy.ReAct("question -> answer", tools=tools, max_iters=5)
            print((await agent.acall(question="What is 25 + 17?")).answer)

asyncio.run(main())
```

## Best Practices

1. Use `acall()` because MCP tools are asynchronous.
2. Initialize the session before listing tools.
3. Keep tool descriptions precise at the MCP server boundary.
4. Apply authentication and authorization before exposing sensitive tools.
5. Set a modest `max_iters` and trace tool use in production.
