DSPy

DSPy does not have native MCP support. Bridge AllMCP into DSPy using langchain-mcp-adapters to convert MCP tools into DSPy-compatible functions.

Install

pip install dspy langchain-mcp-adapters langchain-anthropic

Bridge pattern

import asyncio
import dspy
from langchain_mcp_adapters.client import MultiServerMCPClient


async def get_allmcp_tools_as_dspy():
    """Load AllMCP tools and wrap them for DSPy."""
    client = MultiServerMCPClient({
        "allmcp": {
            "url": "https://go.allmcp.co/mcp/",
            "transport": "streamable_http",
            "headers": {"X-API-Key": "YOUR_API_KEY"},
        }
    })
    lc_tools = await client.get_tools()

    dspy_tools = []
    for tool in lc_tools:
        def make_fn(t):
            def fn(**kwargs):
                return t.invoke(kwargs)
            fn.__name__ = t.name
            fn.__doc__ = t.description
            return fn
        dspy_tools.append(dspy.Tool(make_fn(tool)))

    return dspy_tools

Using with ReAct

import asyncio
import dspy


async def main():
    dspy.configure(lm=dspy.LM("anthropic/claude-sonnet-4-6"))

    tools = await get_allmcp_tools_as_dspy()

    react = dspy.ReAct("question -> answer", tools=tools)
    result = react(question="How many open deals are in my Bitrix24 CRM?")
    print(result.answer)


asyncio.run(main())

Filtering to relevant tools

async def get_bitrix24_tools_for_dspy():
    client = MultiServerMCPClient({...})
    lc_tools = await client.get_tools()
    crm_tools = [t for t in lc_tools if t.name.startswith("bitrix24_")]
    return [dspy.Tool(wrap_lc_tool(t)) for t in crm_tools]
