agtk (Agent Toolkit)

agtk (Agent Toolkit)

• A minimal library to let you focus on building LLM tools. It automatically enables the tools to be used by LLM calls, MCP clients, etc.
• A minimal CLI to install tools and run as MCP server.

Usage

As Package

Develop tools

import agtk

class MinimalFsToolkit(agtk.Toolkit):

    @agtk.tool_def(
        name="read_file",
        description="Read content from a file"
    )
    def read_file(self, file_path: str):
        return open(file_path).read()

    @agtk.tool_def(
        name="write_file",
        description="Write content to a file"
    )
    def write_file(self, file_path: str, content: str):
        with open(file_path, "w") as f:
            f.write(content)

min_fs_toolkit = MinimalFsToolkit()

Use for LLM calls

import litellm
from somewhere import min_fs_toolkit

response = litellm.completion(
    model='openai/gpt-4o-mini',
    messages=[
        { "role": "user",  "content": "hi there, what tools do you have?"}
    ],
    tools=min_fs_toolkit.as_params('openai')
)

Use in MCP server

from mcp import FastMCP
from somewhere import min_fs_toolkit

# Use in mcp
mcp = FastMCP()
min_fs_toolkit.register(mcp)
mcp.run()

As CLI

Standalone as MCP server

# Install a tool (uses pip install under the hood)
agtk install <package_name_or_git_url>

# List installed tools

# List installed tools with details (description and parameters)
agtk list --detail

# Start MCP server with installed tools
agtk mcp

Use with simonw/llm (🚧WIP)
