axio-tools-mcp 0.4.0

MCP tools loader for Axio

axio-tools-mcp

Model Context Protocol (MCP) bridge for axio.

Connect any MCP server to your axio agent. Tools exposed by MCP servers are discovered at runtime and become first-class axio Tool instances — no manual wiring required.

Features

• Dynamic tool discovery — connects to MCP servers and converts their tools into axio Tool instances automatically
• Multiple servers — configure and run several MCP servers simultaneously
• Lifecycle management — handles server startup, shutdown, and reconnection
• TUI integration — ships a settings screen for managing MCP server configuration from within axio-tui

Installation

pip install axio-tools-mcp

Usage

With axio-tui (recommended)

pip install "axio-tui[mcp]"
uv run axio   # MCP Servers section appears in settings

Standalone

from axio_tools_mcp.registry import MCPRegistry
from axio import Agent
from axio.context import MemoryContextStore
from axio_transport_openai import OpenAITransport

async def main() -> None:
    registry = MCPRegistry()
    await registry.init(config=None)

    tools = registry.all_tools   # list[axio.Tool]
    print(f"Loaded {len(tools)} tools from MCP servers")

    agent = Agent(
        system="You are a helpful assistant.",
        tools=tools,
        transport=OpenAITransport(api_key="sk-...", model="gpt-4o"),
    )
    result = await agent.run("Use the available tools to help me", MemoryContextStore())
    print(result)

    await registry.close()

MCP server configuration

MCP servers are configured via the axio-tui settings UI or programmatically:

{
  "servers": [
    {
      "name": "filesystem",
      "command": ["npx", "-y", "@modelcontextprotocol/server-filesystem", "/tmp"]
    },
    {
      "name": "github",
      "command": ["npx", "-y", "@modelcontextprotocol/server-github"],
      "env": {"GITHUB_PERSONAL_ACCESS_TOKEN": "ghp_..."}
    }
  ]
}
