mcp-fabric 0.1.0

Python-first install and control surface for the MCP-Fabric gateway runtime.

MCP-Fabric Python Package

MCP-Fabric provides a Python-first install and control surface for the local gateway runtime. The gateway remains the existing Node.js implementation; Python starts it, validates it, and talks to its HTTP endpoints.

Installation

pip install mcp-fabric

Runtime Dependency

This first Python packaging slice uses the managed Node runtime fallback. Local gateway use requires Node.js >=20. No manual npm install or npm run ... commands are part of the Python API; the Python package verifies runtime dependencies, runs managed bootstrap when needed, and owns startup, readiness checks, logs, and shutdown.

If Node is missing or too old, LocalFabricGateway reports:

Local MCP-Fabric runtime requires Node.js >=20.
Install Node.js, then rerun your Python program.
No manual npm commands are required.

Local Gateway Usage

from mcp_fabric import LocalFabricGateway

with LocalFabricGateway() as fabric:
    client = fabric.client()
    session = client.initialize(client_id="python-user")
    tools = client.tools_list(session.session_id)
    result = client.tools_call(
        session.session_id,
        name="echo",
        arguments={"message": "hello"},
    )

Remote Gateway Usage

from mcp_fabric import FabricClient

client = FabricClient("https://gateway.example.com")
health = client.health()

Operational Proof
