llm-mcp 0.0.2

llm implementation of MCP for clients and servers.

llm-mcp

llm plugin for creating MCP clients and servers.

Installation

pip install llm-mcp

MCP Servers

This package provides a bridge between MCP servers and the llm package, allowing you to use MCP tools with LLM models. The bridge supports both stdio and HTTP-based MCP servers and provides a synchronous interface that's safe to use in any context, including Jupyter notebooks, FastAPI applications, and more.

Command Line Usage

(todo)

Programmatic Usage

For programmatic usage, you can wrap MCP tools as llm.Tool objects:

import os

from llm import get_model
from llm_mcp import wrap_stdio, stdio

# convert stdio tool to llm tools
tools = wrap_stdio(stdio.ServerParameters(
    command="npx",
    args=["-y", "@wonderwhy-er/desktop-commander"],
))

# wrap_mcp(command string) equivalent to wrap_stdio(stdio.ServerParameters)
# from llm_mcp import wrap_mcp
# tools = wrap_mcp("npx -y @wonderwhy-er/desktop-commander")

# Use the tools with a model
model = get_model("gpt-4.1-nano")
response = model.chain(
    f"Display the text found in the secret.txt file in {os.getcwd()}",
    tools=tools,
)
print(response.text())

Output:

The text found in the secret.txt file is: "Why don't pelicans like to tip waiters?"

HTTP Servers

For HTTP-based MCP servers, use the HTTP bridge instead:

from llm import get_model

from llm_mcp import wrap_http, http

tools = wrap_http(http.ServerParameters("https://gitmcp.io/simonw/llm"))

# wrap_mcp(url) is equivalent to wrap_http(http.ServerParameters)
# from llm_mcp import wrap_mcp
# tools = wrap_mcp("https://gitmcp.io/simonw/llm")

model = get_model("gpt-4.1-nano")

response = model.chain(
    "Search llm github for CHANGELOG and display 1 sentence summary of the latest entry.",
    tools=tools,
)
print(response.text())

Output:

The latest entry in the changelog (version 0.26a0, dated 2025-05-13) introduces alpha support for tools in LLM, allowing models with tool capability (including the default OpenAI models) to execute Python functions as part of responding to a prompt, with usage available in both the command-line interface and Python API, and support for defining new tools via plugin hooks.
